How to create RESTful Web Service with Spring Boot and Apache Camel?

I'm learning Apache Camel in Spring Boot project and I try to create a Retful Webservice and the service is starting but the problem is that I get 404 when I call the endpoint.
#Component
#RequiredArgsConstructor
public class RestJavaDsl extends RouteBuilder {
private final WeatherDataProvider weatherDataProvider;
#Override
public void configure() throws Exception {
from("rest:get:javadsl/weather/{city}?produces=application/json")
.outputType(WeatherDto.class)
.process(this::getWeatherData);
}
private void getWeatherData(Exchange exchange) {
String city = exchange.getMessage().getHeader("city", String.class);
WeatherDto currentWeather = weatherDataProvider.getCurrentWeather(city);
Message message = new DefaultMessage(exchange.getContext());
message.setBody(currentWeather);
exchange.setMessage(message);
}
}
I created this class to hardcode some data:
#Component
public class WeatherDataProvider {
private static Map<String, WeatherDto> weatherData = new HashMap<>();
public WeatherDataProvider() {
WeatherDto dto = WeatherDto.builder().city("London").temp("10").unit("C").receivedTime(new Date().toString()).id(1).build();
weatherData.put("LONDON", dto);
}
public WeatherDto getCurrentWeather(String city) {
return weatherData.get(city.toUpperCase());
}
public void setCurrentWeather(WeatherDto dto) {
dto.setReceivedTime(new Date().toString());
weatherData.put(dto.getCity().toUpperCase(), dto);
}
}
#Data
#NoArgsConstructor
#AllArgsConstructor
#Builder
public class WeatherDto implements Serializable {
static int counter = 1;
private int id = counter++;
private String city;
private String temp;
private String unit;
private String receivedTime;
}

But when I try to call the endpoint http://localhost:8080/services/javadsl/weather/london
It looks like this endpoint doesn't exist, the rest isn't created. I used debugger and the method getWeatherData() isn't called.
And I think this log is not ok: Started route1 (rest://get:javadsl/weather/%7Bcity%7D), it should be something like that: route1 started and consuming from servlet:/javadsl/weather/%7Bcity%7D
And the tutorial is from here: https://www.youtube.com/watch?v=spDjbC8mZf0&t=433s
Thank you in advance!

You can start by creating example project using official camel-archetype-spring-boot maven archetype. You can generate project based on the archetype using your IDE or from command-line using following maven command.
mvn archetype:generate -DarchetypeArtifactId="camel-archetype-spring-boot" -DarchetypeGroupId="org.apache.camel.archetypes" -DarchetypeVersion="3.14.0"
Now in the maven project file pom.xml add following block to the dependencies
<dependency>
<groupId>org.apache.camel.springboot</groupId>
<artifactId>camel-jetty-starter</artifactId>
</dependency>
Note that version doesn't need to be specified as it is provided by camel-spring-boot-dependencies BOM (bill of materials) in dependencyManagement section.
After that you can create new file ConfigureCamelContext.java where we can configure our CamelContext and provide it with RestConfiguration. We can do this by implementing CamelContextConfiguration and #Component annotation.
The annotation tells spring-framework that it should create instance of the class and inject it to objects that request it based on its class-type or interface. Camel is configured to automatically ask spring-framework for these RestConfiguration instances which it will proceed to use configure CamelContext.
package com.example;
import org.apache.camel.CamelContext;
import org.apache.camel.spi.RestConfiguration;
import org.apache.camel.spring.boot.CamelContextConfiguration;
import org.springframework.stereotype.Component;
#Component
public class ConfigureCamelContext implements CamelContextConfiguration {
#Override
public void beforeApplicationStart(CamelContext camelContext) {
RestConfiguration restConfiguration = new RestConfiguration();
restConfiguration.setApiComponent("jetty");
restConfiguration.setApiHost("localhost");
restConfiguration.setPort(8081);
camelContext.setRestConfiguration(restConfiguration);
}
#Override
public void afterApplicationStart(CamelContext camelContext) {
}
}
This should work with RestDSL and rest-component.
Edit MySpringBootRouter.java to something like this:
package com.example;
import org.apache.camel.Exchange;
import org.apache.camel.builder.RouteBuilder;
import org.springframework.stereotype.Component;
#Component
public class MySpringBootRouter extends RouteBuilder {
static final String CONTET_TYPE_TEXT = "text/plain";
#Override
public void configure() {
rest()
.get("/hello/")
.route()
.setHeader(Exchange.CONTENT_TYPE, constant(CONTET_TYPE_TEXT))
.setBody().constant("Hello world")
.end()
.endRest()
.get("/hello/{name}")
.route()
.setHeader(Exchange.CONTENT_TYPE, constant(CONTET_TYPE_TEXT))
.setBody().simple("Hello ${headers.name}")
.end()
.endRest();
from("rest:get:test?produces=plain/text")
.setBody().constant("Hello from JavaDSL");
}
}
Comment out the class under src/test/java/<grouId>/ as the example test provided by the archetype is not applicable for for MySpringBootRouter and will interrupt build.
To run the project you can use command
mvn spring-boot:run
Now you should be able to open up localhost:8081/hello, localhost:8081/hello/<Name> or localhost:8081/test get response in plain text.

How to fix 'Attribute "default-dependency-check" must be declared for element type "beans".' error in Spring 5

I tried to upgrade Spring from version 4 to version 5 (spring-boot 1.5.x to 2.x.x) in a REST spring boot application. When parsing a config/bean definition file from one of the libraries an error occurs Attribute "default-dependency-check" must be declared for element type "beans"., but that happens only if mentioned attribute - default-dependency-check - is present in the file.
Please note that this config file comes from library that I have no control over, therefore I cannot change the version of spring beans dtd, or simply modify the contents of the file, the processing of the file also happens inside the library and seems to be crucial for the application.
This problem did not occur with spring-boot 1.5.x.
How can I fix/work around this error? Can I make spring ignore the dtd version used in the file?

Spring boot web app not running on tomcat 9

My web App works fine on Eclipse Photon STS, java 8 and Spring Boot 2.02 with the embeded tomcat using endpoint:
http://localhost:8081/DataViewer/tspsPatentSearch
But when I compile the code into DataViewer.war file (using mvn package) and run it on Tomcat 9 on Linux
with endpoint:
http://myserver.com:8081/DataViewer/tspsPatentSearch
I get the infamous:
Whitelabel Error Page
There was an unexpected error (type=Not Found, status=404).

In application.properties I have:

My MainController.java has:
#GetMapping("/tspsPatentSearch")
public String tspsPatentSearch(Model model) {
model.addAttribute("tspsPatent", new TspsPatent());
return "tspsPatentSearch";
}
The war file unpacks fine and there are no errors. In catalina.out we have:
2018-10-04 12:09:09.954 INFO 12950 --- [ main] s.w.s.m.m.a.RequestMappingHandlerMapping : Mapped "{[/tspsPatentSearch],methods=[POST]}" onto public java.lang.String com.clarivate.dataviewer.controller.MainController.tspsPatentSearch(com.clarivate.dataviewer.model.TspsPatent,org.springframework.ui.Model,org.springframework.validation.BindingResult)
and no errors. I've tried this ie my package structure is correct and this ie my jsp's are in the correct location (data_viewer\src\main\webapp\WEB-INF\jsp)
and i'm now running short of ideas. Any help much appreciated
Edit: If I copy tspsPatentSearch.jsp into the war file top directory then tomcat finds it. So it looks like tomcat is ignoring:
spring.mvc.view.prefix=/WEB-INF/jsp/
or not finding application.properties at all.

Add this to your application.properties:
server.servlet.contextPath=/
I've taken your sample code and, assuming you annotated your MainController simply as #Controller, put a deployment together. I changed a few things around, but I believe this was the bit that did it. I haven't been able to find any references explaining why it might be required by Tomcat, but I intend to keep looking. I'll update you if I find anything.
Edit:
I noticed some duplicate logging in Spring 2.0.2 related to this issue: https://github.com/spring-projects/spring-boot/issues/13470
The problem appeared fixed in 2.0.4 therefore I upgraded.
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.0.4.RELEASE</version>
<relativePath /> <!-- lookup parent from repository -->
</parent>
Additionally, I removed the server.servlet.contextPath=/ entry and tada I still can reach the Hello World jsp I set up. If upgrading is possible for you, maybe you could try that before adding something to application.properties which could be considered duplicated functionality. At least I can promise you a better logging experience.
Edit #2:
No smoking gun, so far, but these (from 2.0.4) could be related:
Provide a consistent way to discover the primary DispatcherServlet's path
Dispatcher servlets with a custom servlet name are not found by the mappings endpoint
Nothing looked likely on a surface scan of 2.0.3. I'm going to give it a rest for now and give you a chance to try some stuff. Good luck!
Edit #3:
I'm sorry to continue suggesting you switch environment stuff around, but one difference I noted between what I tested and what you're working with is that you seem to be using Tomcat-9.0.0.M20 where as I was testing with 9.0.12.
Whether you want to upgrade or not, a few things to note and/or do:
1) Update your question with what you've got now if it's different than before. Include the server.servlet.contextPath=/ in your application.properties just so anyone else looking can see what you've done.
2) The exclusion you have for spring-boot-starter-tomcat under spring-boot-starter-web doesn't appear to do anything - you can verify by comparing the output from running mvn dependency:tree before and after removal.
3) I'm not sure that your spring-web dependency is needed either, as that's brought in by default under the spring-boot-starter.
4) Now to your output. Spring Boot is coming up (note the banner) and your classes are being found and acted upon.

And I do indeed note the mapping to /error that's returned for your request at 09:32:11.
I find this strange:
2018-10-12 09:32:11.758 DEBUG 55745 --- [nio-8081-exec-1] o.s.web.servlet.DispatcherServlet : DispatcherServlet with name 'dispatcherServlet' processing GET request for [/DataViewer/DataViewer/error]
And it's different in DS.log:
2018-10-12 08:36:56.136 DEBUG 6992 --- [nio-8081-exec-1] o.s.web.servlet.DispatcherServlet : DispatcherServlet with name 'dispatcherServlet' processing GET request for [/DataViewer /error]
Specifically /DataViewer/DataViewer/error - have you tried requesting http://localhost:8081/DataViewer/DataViewer/tspsPatentSearch
In general this appears as though everything is coming up but there is a misconfiguration somewhere that isn't allowing a request to map to the handler.

To confirm.
Tomcat adds the war file name to the end point, so if we create DataViewerX.war and set :
server.servlet.path=/DataViewer
then the end point when running on an external tomcat is:
myServer.com/DataViewerX/DataViewer/tspsPatentSearch
but when we run on Eclispe, using the source code, then the end point is:
http://localhost:8081/DataViewer/tspsPatentSearch
which is a bit annoying but not a major problem. A way round this is to call the war file ROOT.war, then tomcat ignores the war file name and the 2 end points are the same, but I have multiple war files in the webapps dir so this solution isn't acceptable for me.
If anyone know's a way to allow the 2 end points to be the same then please say so, but it's not that important.

Spring cloud config cannot load native config file unless the filename is application

Something strange happened to me. I have no idea about how to solve it that the spring cloud config cannot load native or cloud config file unless it's filename is 'application.yml/application.properties'.
The below code is my configuration:
pom.xml:

The shared folder structor:
resources
-- shared
-- -- application-dev.yml
-- -- sms-dev.yml
It looks good and run well with no errors, but when I visit http://127.0.0.1:8000/configCenter/dev/master, it only shows the application property source.
The response:

All above shows the 'application.yml' file only worked.
Can someone help me? Thanks very much!

The external config can help you that. The detail is here: http://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-external-config.html
You can change this default application config to the external one by command like in the guide line:
If you don’t like application.properties as the configuration file
name you can switch to another by specifying a spring.config.name
environment property. You can also refer to an explicit location using
the spring.config.location environment property (comma-separated list
of directory locations, or file paths).
$ java -jar myproject.jar --spring.config.name=myproject or
$ java -jar myproject.jar
--spring.config.location=classpath:/default.properties,classpath:/override.properties
Or in your code you can put it like:
new SpringApplicationBuilder(Application.class)
.properties("spring.config.name:YOUR_EXTERNAL_CONFIG_FILE")
.build()
.run(args);
}
Hope this help.

As #spencergibb said, if I want to load sms-dev.yml, I should rename application.name to sms.

Spring-Boot and MySql unable to connect

I am trying to connect to mysql database, but it's not working. I took a course from udemy and followed all steps, but i am getting always the same error, then I followed the steps from this and this guides, but doesn't work.
Things i tried so far:
new IDE
clean & rebuild project
deleting property spring.datasource.driverClassName = com.mysql.jdbc.Driver from application.properties
tried to add Mysql Connector manually
I've ran out of ideas. Need some assistance

User Entity
#Entity
public class User {
private String name;
private String surname;
private String password;
#Id
#GeneratedValue (strategy= GenerationType.AUTO)
private String userId;
private String email;
private String phoneNo;
private String PIN;
private List<Appointment> appointmentList;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
//getter and setter
UserDaoRepository
#RepositoryRestResource(collectionResourceRel = "user", path = "user")
public interface UserDaoRepository extends JpaRepository<User, Long>{
User findByName(#Param("name") String name);
User findByEmail(#Param("email") String email);
}

Try adding this to your maven project file:
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>5.1.6</version>
</dependency>
Your application.properties file is just telling spring what jpa provider to use. You still have to include the jdbc provider implementation files.

You need to define the ORM association for this field :
private List<Appointment> appointmentList;
For example if a User may have multiple Appointment and an Appointment may be related to zero or one User, you could define the Appointment relationship in this way in the User entity :
#Entity
public class User{
...
#OneToMany(mappedBy="user")
private List<Appointment> appointmentList;
}
And in the Appointment entity you could define this relationship :
#Entity
public class Appointment{
...
#ManyToOne
private User user;
...
}
If you encounter other mapping errors, I advise you to understand the Hibernate/JPA basics.
Here is the actual documentation of Hibernate (v 5): http://docs.jboss.org/hibernate/orm/5.2/userguide/html_single/Hibernate_User_Guide.html
Here is the documentation part on the relationships definition between entities :
