Spring Boot 2 Actuator endpoints inaccessible with Jersey

Spring Boot 2 Actuator endpoints inaccessible with Jersey - java

I have a very simple demo application using the Spring Boot 2.0.x.RELEASE
In my POM I have:
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.0.4.RELEASE</version>

My main application just looks like:
#SpringBootApplication
public class DemoApplication {
public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
}
#Bean
ResourceConfig getJerseyConfig() {
final HashMap<String, Object> jerseyProperties = new HashMap<>();
jerseyProperties.put(ServerProperties.MEDIA_TYPE_MAPPINGS, "json : application/json");
ResourceConfig resourceConfig = new ResourceConfig()
.register(TestEndpoints.class);
resourceConfig = resourceConfig.setProperties(jerseyProperties);
return resourceConfig;
}
}
When I then try and hit an actuator endpoint such as /actuator I receive a 404, but I can hit the endpoints in TestEndpoints.java with no problem. I had this working with Spring Boot 1.5.x, but now it seems that Jersey is not allowing the actuator endpoints through. If I remove the ResourceConfig bean completely, then I can hit the actuator endpoints. Is there some configuration I have to add to allow the actuator endpoints through jersey?

It's because by default Jersey will use the url mapping /*, which will hog up all requests, including those to the actuator endpoints, which it will not find. There are two solutions; you can either change the base URL for Jersey to something else, e.g. /api/* or you can configure Jersey as a filter (instead of the default servlet) and set a property to make Jersey forward all requests it doesn't know down to the servlet container. Both examples can be found in this post.

Springboot Actuator Refresh does not reload #Value properties in #ConfigurationProperties

I have a springboot application that ingests an application.properties via #ConfigurationProperties and #PropertySource("classpath:application.properties"). My desire is to reload these properties on the fly for the purposes of support. When I POST to http://localhost:8080/actuator/refresh I get a 200 OK response but the body is empty, which I think implies no #RefreshScopes have been refreshed but I'm not sure. I have read and viewed most docs and SO while trying various things but haven't managed to reload a new value.
Here is my app:
application.properties:
# suppress inspection "UnusedProperty" for whole file

public void onRefresh(RefreshScopeRefreshedEvent event) {

System.out.println(this.ClientAPIEndpoint);
}
}
The event listener fires without issue too and it will successfully print the value from application.properties. I have debugged main below and all values are populated without issue.
I suspect the issue is here but I'm not sure what I'm doing wrong in main()

public static void main(String[] args) throws Exception {

ConfigurableApplicationContext appContext = SpringApplication.run(Integration.class, args);
// Get ApplicationProperties
ApplicationProperties properties = appContext.getBean(ApplicationProperties.class);
SERVER_ADDR = (Objects.equals(properties.getEnv(), "DEV")) ? "0.0.0.0" : "localhost";
// Start Camel Context Engine
context = new DefaultCamelContext();
// Feed Camel our defined routes & start
RouteBuilderAutoLoader.loadRoutes(context);
context.start();
}
}
The last thing I'm unsure of is if I have the necessary dependencies or if I'm missing something here.

Edit 12/04/2022
Completely redid my classes with #ConfigurationProperties
So when I post to refresh the values in propertySource for AWS automatically update. So eg I change cobaltdlt to cobaltdlttest below, hit refresh, and then I can see the change when I query GET http://localhost:8080/actuator/env
So the refresh is working but it's not reflective in the #Component beans even though the propertySource is updating. In fact the only beans it is working with are the AWS beans.

Have you tried a PropertiesConfiguration bean? See here: https://www.baeldung.com/spring-reloading-properties.
Once configured correctly, it should automatically read changes to your properties file and reload them. Also, there are some limitations that are mentioned in that article that you should be aware of.

#I2obiN. As you have mentioned that ApplicationProperties is getting refreshed by Refresh Scopes, therefore actuator refresh is working properly.
But I noticed that you are using RefreshScope on main application class. IMO this actuator management/refresh will not restart application. You can try to create an extra method that reinitializes Camel Context.
Hope this helps!!
https://www.baeldung.com/java-restart-spring-boot-app#actuators-restart-endpoint

You can invoke the refresh Actuator endpoint by sending an empty HTTP POST to the client's refresh endpoint: http://localhost:8080/actuator/refresh . Then you can confirm it worked by visiting the http://localhost:8080/message endpoint.
And once you refresh, try to rebind immediately by calling the POST endpoint http://localhost:8080/actuator/env
This worked on a spring boot I tried and it reloads the values and you can see it in the stack trace.
I tried doing a field in spring data source with the given payload to Rebind and it reloads Example as the value.
Payload:
{"name":"spring.datasource.userName", "value":"Example"}
In the application.properties, add the following
management.endpoint.env.post.enabled=true
management.endpoint.restart.enabled=true
endpoints.sensitive=true
endpoints.actuator.enabled=true
management.security.enabled=false
management.endpoints.web.exposure.include=*

Java app working when running spring boot but not with Apache

I created an app using https://start.spring.io/ so when I run ./mvnw spring-boot:run the apps work great. But then in order to be able to debug my app (as I always did with others) I select "Debug On Server" and the server compile successfully with the message INFORMACIÓN: Server startup in 4288 ms
But when I try to access to the app I get 404 error.

Thhis is my controller:
#RestController
#RequestMapping(
value = "/api/products",
consumes = MediaType.APPLICATION_JSON_VALUE,
produces = MediaType.APPLICATION_JSON_VALUE
)
public class ProductController {
#Autowired
ProductService productService;
#GetMapping("")
#ResponseStatus(HttpStatus.OK)
public String getAllProducts() {
return this.productService.initCrawler();
}
}
And the URL I'm pointing is:
http://localhost:8080/app/api/products
And the response is HTTP 404
Also eclipse after the build open the explorer in http://localhost:8080/app but it gets also 404.
When running directly with ./mvnw spring-boot:run the URL that works fine is http://localhost:8080/api/products which is not working neither when I use Run as Server
And in the logs doesn't say anything...

I understood your question this way. You have created a spring boot application from Spring Initializr and the application run successfully from command line but not when you are trying to deployed in server and start the server in debug mode.
You should know that Spring Initializr created a spring boot application which is stand-alone, production-grade Spring based Applications that you can "just run". With stand-alone meaning the the server is incorporated as dependency in spring boot app and you don't need to deployed in server.
If you want to deploy in server , you need to make Spring Boot Application #SpringBootApplication class extend the SpringBootServletInitializer class.
#SpringBootApplication
public class DemoApplication extends SpringBootServletInitializer {
#Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(DemoApplication.class);
}
public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
}
}
You should specify in maven the main class that is going to run and change the packaging from jar to war.
<packaging>war</packaging>
<start-class>com.tutorialspoint.demo.DemoApplication</start-class>
For more information how to make you spring boot application to be deployed in server, check the link : https://www.tutorialspoint.com/spring_boot/spring_boot_tomcat_deployment.htm
If you don't need the application to run on the server , you just want to debug the code. I would suggest to use eclipse or intellij. You include spring boot dashboard in perspective and start the spring boot application in debug mode. Check this link to understand how to include and use spring boot dashboard : https://medium.com/danielpadua/java-spring-boot-eclipse-744454468670

Problem hitting REST endpoint in Spring Boot 2.2.0 application

I try to create a Spring Boot REST application with GraphQL and MongoeDB (I start from that article https://medium.com/oril/spring-boot-graphql-mongodb-8733002b728a). The application start but I got 404 error when I try to post something to a endpoint.
I read also that #PostConstruct is not supported anymore with 2.2.0 (it's another problem I'll try to figure out later, I try to preload the database during startup).

My main application file look like this (nothing very special!):
#SpringBootApplication
public class DemoApplication {
public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
}
}
MainController.java
#RestController
#RequestMapping(path = "/query")
public class MainController {
private GraphQL graphQL;
private GraphQlUtility graphQlUtility;
#Autowired
MainController(GraphQlUtility graphQlUtility) throws IOException {
this.graphQlUtility = graphQlUtility;
graphQL = graphQlUtility.createGraphQlObject();
}
#PostMapping(path= "/")
public ResponseEntity query(#RequestBody String query){
ExecutionResult result = graphQL.execute(query);
System.out.println("errors: "+result.getErrors());
return ResponseEntity.ok(result.getData());
}
}
When I post on http://localhost:8080/query, I got this error:
{
"timestamp": "2019-10-19T16:10:19.136+0000",
"status": 404,
"error": "Not Found",
"message": "No message available",
"path": "/query"
}

It will match /query/ only but not /query . If you want to match both /query and /query/ , you can just leave path of the #PostMapping in the query method as the default.
#RestController
#RequestMapping(path = "/query")
public class MainController {
#PostMapping
public ResponseEntity query(#RequestBody String query){
}
}

There could be a reason for this error that Spring boot is not scanning this class. Please try to add ComponentScan annotation on Spring boot main class with the package where you keep your controllers as given below.
#ComponentScan(basePackages= {"com.example"})

Check the port on which your Spring Server is running, According to the medium post they have configured it to run on :8000 while you're hitting on :8080.
The error states the same that it cannot find any controller mapped to this api-endpoint.
http://localhost:8000/query/

Spring boot Configuration :
Springboot configuration file
#Configuration
public class WebConfiguration {
#Bean
ServletRegistrationBean h2servletRegistration(){
ServletRegistrationBean registrationBean = new ServletRegistrationBean( new WebServlet());
registrationBean.addUrlMappings("/console/*");
return registrationBean;
}
}

to use the H2 console you need to configure it in your .properties file
spring.h2.console.enabled=true
spring.h2.console.path=/h2console/
where /h2console/ is the path you want to use on the browser so you can change it to anything. Also if you have security enabled you might want to add it to the permitted paths
also add this to your HttpSecurity configuration http.headers().frameOptions().disable();
Edit
change your security configuration i'm pretty sure you might have spring security in your pom so use this instead, if not it should work
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
#Configuration
public class WebConfiguration extends WebSecurityConfigurerAdapter {
#Override
protected void configure(HttpSecurity httpSecurity) throws Exception {
httpSecurity.authorizeRequests().antMatchers("/").permitAll().and()
.authorizeRequests().antMatchers("/console/**").permitAll();
httpSecurity.csrf().disable();
httpSecurity.headers().frameOptions().disable();
}
}

If have included spring-boot-starter-security artifact in your pom then by default basic authentication is enabled. Hence, to access your console either you disable the basic authentication by adding security.basic.enabled=false in your application.properties or allow the access in your configure method as below:
#Configuration
public class SecurityConfig extends WebSecurityConfigurerAdapter {
#Override
protected void configure(HttpSecurity httpSecurity) throws Exception {
httpSecurity.csrf().disable().authorizeRequests().antMatchers("/").permitAll().and().authorizeRequests()
.antMatchers("/console/**").permitAll();
httpSecurity.headers().frameOptions().disable();
}
}

Thank you all for your generous help.The application class (Springboot) was in a separate package and it was not scanning other packages.Also I modified my Pom.xml a bit which finally helped me to access the console.Attached is my new Pom.xml.

rebuild your project

this might help folks , all the configuration above is correct
Note - if you are not using any security then adding spring security is not required
Actualy problem is - when you open this url in chrome
http://localhost:8080/h2 chrome makes it --> https://localhost:8080/h2
To get rid of this issue - Below reference will help -
Google Chrome redirecting localhost to https

You might have face 2 situation including following errors:
localhost refused to connect
Double check the URL. Chrome automatically try to change http:// to https://
Check spring.h2.console.path (Path at witch the console avilible) to get your URL:
Default: /h2-console --> URL: http://localhost:8080/h2-console/
If you running IDE (e.g. IntelliJ Idea), make sure your app is running witch means your H2 data base is running!
You face 404 Error:
In this case your H2 Data base is correctly running on Port 8080 and you already have the connection with it.
Check spring.h2.console.path (Path at witch the console avilible) to get your URL:
Default: /h2-console --> URL: http://localhost:8080/h2-console/
Enable H2 Console
spring.h2.console.enabled=true

The issue might be also be caused by adding server.servlet.context-path to properties. The new url will be composed of server.servlet.context-path plus spring.h2.console.path

If you have renamed the h2 path in the application.properties to "console" you've to add it in your antMatcher like .antMatcher("/console/**") with two asterisks after the "console" because there are much more appendings.

If none of the above solution works, try below one, this worked for me :
Add below property in your application.propertiesfollowing
spring.data.jpa.repositories.bootstrap-mode=default
Open console in browser using this URL : http://localhost:8080/h2-console
On a login page make sure that you use jdbc:h2:mem:testdb as JDBC URL.

As h2 database console is mapped to "h2-console".
Use this:
http.csrf().disable().authorizeRequests()
.antMatchers("/h2-console/**").permitAll()
.anyRequest().authenticated();
// disable frame options
http.headers().frameOptions().disable();
`
You don't need permit root access:
.antMatchers("/") * NOT NEEDED *

Unable to access and use static resources in Spring Boot Application

I have been fighting with getting resources to work for quite sometime now, and I know there are thousands of similar questions.. Anyway, my condition is this
I will start with my pom.. I might have missed something here?

Here are the errors I am dealing with
And in the terminal I see this
Looking up handler method for path /css/bootstrap/css/bootstrap.min.css
Did not find handler method for [/css/bootstrap/css/bootstrap.min.css]
Request method 'GET' not supported
What does this mean?
I have a correct structure and doing it by the convention
But no luck what so ever. I tried changing to public/ and tried using webjars. All in vain. What are the norms for this and how do I get this set up so it wont be breaking! Thanks!
EDIT:: Configuration Files
Here is my application file that is provided with the spring boot
#SpringBootApplication
#EnableAutoConfiguration(exclude = {
org.springframework.boot.autoconfigure.security.SecurityAutoConfiguration.class,
org.springframework.boot.actuate.autoconfigure.ManagementSecurityAutoConfiguration.class})
#ComponentScan(basePackages = {"webapp"})
#EnableJpaRepositories
public class SpringDemoApplication {
public static void main(String[] args) {
ApplicationContext ctx = SpringApplication.run(SpringDemoApplication.class, args);
}
}
And I have a WebConfig file which is mostly empty, but I tried adding the #Overide on addResourceHandlers, with no improvements
#Configuration
#EnableWebMvc
#ComponentScan(basePackages = {"webapp"})
public class WebConfig extends WebMvcConfigurerAdapter {
#Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("/resources/**").addResourceLocations("classpath:/resources/static/").setCachePeriod(31556926);
}
}
EDIT
After further examining the application, I have found this
It says that the request it allows is PUT, but why? From what I can understand is that something is blocking my request to the resource files, is that right?
Desperate to get this fixed, it's really bothering to configure Spring, even with Spring Boot!

Found a problem that I was facing with not being able to access static resources.
For those who experience the same:
This behaviour (405 error) signifies that something is blocking the path to your static resources. This doesn't have to be /static or /public. It wont do anything.
In my case the problem was that a controller was blocking the /css path. To fix this a #RequestMapping(value = "/Somepath") annotation on the class lvl is needed to release the path for the static resources.
This worked for me and now I can access my static resources without any issues.
This can be a very annoying problem and someone can spend hours and days trying to figure this out. Hope this helps others to save their time
If there are alternative or other methods of preventing this behaviour that please mention in the comments

If you are trying to configure resource mapping through configuration class as you mentioned in comment, then it should be like this:
#EnableWebMvc
#ComponentScan(basePackages = {"org.company.yourpackage"})
#Configuration
public class AppConfig extends WebMvcConfigurerAdapter {
#Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("/resources/**").addResourceLocations("classpath:/resources/static/").setCachePeriod(31556926);
}
}
this post also may help.

I was having the exact same issue, What helped me was adding:
enter code here
<servlet-mapping>
<servlet-name>default</servlet-name>
<url-pattern>*.js</url-pattern>
</servlet-mapping>
OR
<servlet-mapping>
<servlet-name>default</servlet-name>
<url-pattern>/js/*</url-pattern>
</servlet-mapping>
from this post
servlet for serving static content here
