UnsatisfiedDependencyException with springboot - java

I'm with difficulties on SpringBoot. I'm following a course class, my code it's exactly equals of my professor but my code give me this error(I've tried to fix this with many solutions like creating a bean in another .xml, annoting in the main class with #EntityScan and #ComponentScan, nothing worked for me):

Solved: Added #EnableJpaRepositories(basePackages = "my.package.*") in the Main class above or below #SpringBootApplication and adding the dependency on pom.xml like Jacob and Hussain said, thanks guys!


Above exception/error is thrown because java class loader unable to find the class "PersistenceAnnotationBeanPostProcessor" which is available under the artifact "spring-orm".
Issue should get resolved by adding below dependency
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
After adding above dependency it may fail with "Failed to configure a DataSource" because there are no database configurations defined in your project. You can use embedded database by adding below dependency. Below H2 dependency brings up in-memory database.
<dependency>
<groupId>com.h2database</groupId>
<artifactId>h2</artifactId>
</dependency>

spring-boot 3.0.0 GraaVM for interface jakarta.servlet.http.HttpServletRequest

Just testing some Spring Boot 3.0.0 with GraalVM Native and got some queries regarding it as I could not find properly documentation regarding it.
So, I've started a new project with GraalVM Native Support and Spring Web depedencies on Spring Initializr (https://start.spring.io/).
Then, for testing native image purposes I have my DemoApplication class like as follows:
package com.example.demo;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import jakarta.servlet.http.HttpServletRequest;
#SpringBootApplication(proxyBeanMethods = false)
public class DemoApplication {
#Autowired
private HttpServletRequest request;
public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
}
}
As a result to build a native image, have used command as follows:
mvn -Pnative spring-boot:build-image
The image was successfully compiled and created:
docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
paketobuildpacks/run tiny-cnb c71fb787280a 3 days ago 17.3MB
paketobuildpacks/builder tiny cf7ea4946a20 42 years ago 588MB
demo 0.0.1-SNAPSHOT 7794949d07ce 42 years ago 96.9MB
When I run this "demo" image using:
docker run demo:0.0.1-SNAPSHOT
It shows the following exception:

I assume that must be something related to inform a implementation for interface jakarta.servlet.http.HttpServletRequest, however I don't how to inform/configure it.
Do you guys have any suggestion(s)?
Thanks in advance.

After several readings on Spring Boot 3.0.0 (https://docs.spring.io/spring-boot/docs/current/reference/htmlsingle/) user guide, have figured out that some classes Spring AOT needs a runtime hint as a result to compile it into a native program.
If the class is not found you need to create a custom hint (https://docs.spring.io/spring-boot/docs/current/reference/htmlsingle/#native-image.advanced.custom-hints).
So to have it worked I have created a HTTPServletRequest runtime hint (bear in mind that must implements interface org.springframework.aot.hint.RuntimeHintsRegistrar) class as follows:
public class HttpServletRequestRuntimeHint implements RuntimeHintsRegistrar{
#Override
public void registerHints(RuntimeHints hints, ClassLoader classLoader) {
try {
ProxyHints proxies = hints.proxies();
proxies.registerJdkProxy(HttpServletRequest.class);
} catch (Exception e) {
throw new RuntimeException("Could not register RuntimeHint: " + e.getMessage());
}
}
}
And then it needs to be informed on a #Configuration class or, for example, your #SpringBootApplication annotated application class to activate those hints:
#SpringBootApplication
#ImportRuntimeHints(value = {HttpServletRequestRuntimeHint.class})
public class DemoApplication {
#Autowired
private HttpServletRequest request;
public static void main(String[] args) {
SpringApplication.run(ApplicationConfig.class, args);
}
}
And done!
Hope that helps!
Thank you.

I faced same issue when i was beginner in Spring Framework. If put #Service annotaion on interface then service interface become useless so, Remove #Service annotation from WorkerService and put this annotation in WorkerServiceImpl.

Whitelabel Error Page This application has no configured error view, so you are seeing this as a fallback

I am started building a spring boot application but i am getting this type of error "Whitelabel Error Page - This application has no configured error view, so you are seeing this as a fallback."
I created the project from https://start.spring.io/.

I don't understand what is the problem.

Try adding #RestController annotation to the class

maybe you should use html file to run it in browser in my opinion,and also if you use thymeleaf include the dependencies as well

Java controller always return a 404 no matter what I do

I was following an example from the spring boot documentation and the java controller always returns a 404 for some reason
This is what I tried
package com.example.accessingdatamysql;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;
#Controller // This means that this class is a Controller
#RequestMapping(path="/demo") // This means URL's start with /demo (after Application path)
public class MainController {
#Autowired // This means to get the bean called userRepository
// Which is auto-generated by Spring, we will use it to handle the data
private UserRepository userRepository;
#PostMapping(path="/add") // Map ONLY POST Requests
public #ResponseBody String addNewUser (#RequestParam String name
, #RequestParam String email) {
// #ResponseBody means the returned String is the response, not a view name
// #RequestParam means it is a parameter from the GET or POST request
User n = new User();
n.setName(name);
n.setEmail(email);
userRepository.save(n);
return "Saved";
}
#GetMapping(path="/all")
public #ResponseBody Iterable<User> getAllUsers() {
// This returns a JSON or XML with the users
return userRepository.findAll();
}
}
which is the example given by spring boot here https://spring.io/guides/gs/accessing-data-mysql/
Then I also tried
#RestController
#RequestMapping("/demo")
public class GreetingClass {
#GetMapping("/greeting")
public String getGreeting() {
return "hello";
}
}

I know this is weird, I set up everything as instructed on the page but apparently nothing works, and I also checked other questions similar to this none of them answer my question.
It does seem that the tomcat server is hit, because it says when I make a call
o.s.web.servlet.DispatcherServlet : Completed initialization in 9 ms
but then I get with this call curl 'http://localhost:8080/demo/greeting' and with 'http://localhost:8080/demo/all'
curl : The remote server returned an error: (404) Not Found.

}
This works if I do this:
https://github.com/BraintoByte/Test_App_Stack/tree/master/demo
Different example:
I have attached a different example with hirarchy exactly the same but business logic omitted:
Code in controller:
package com.braintobytes.controllers;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.bind.annotation.RestController;
import com.braintobytes.data.Currency;
import com.braintobytes.data.repository.CurrencyRepository;
#RestController
#RequestMapping("/demo")
public class CurrencyController {
#Autowired
private CurrencyRepository currencyRepository;
#GetMapping("/currency")
public String getCurrency() {
return "currency";
}
}
Project hierarchy:
Same exact pom and in application.properties:
spring.jpa.hibernate.ddl-auto=update
spring.datasource.url=jdbc:mydatabase
spring.datasource.username=myusername
spring.datasource.password=mypassword

Your controller is in package - com.example.accessingdatamysql
Spring boot startup log shows your main application class c.b.f.FinanceMicroserviceApplication is in another non related package hierarchy.
Spring boot recommends to locate main application class in a root package above other classes so that the component scan works out of box.
If you keep package com.example as root package and move your main application class FinanceMicroserviceApplication to it then everything should work as expected.
If you don't follow Spring boot recommendation for package hierarchy then you need to explicitly specify packages to scan with #SpringBootApplication annotation.

Alright so none of the suggestions above worked, we were on the right path though.
Changing the structure as so worked:
There was also a pathing problem in the application.properties and thus I changed as so:
spring.datasource.url=jdbc:mysql://${MYSQL_HOST:localhost}
To:
jdbc:mysql://localhost
And finally:
package com.braintobytes.finance.data.repository;
import org.springframework.data.repository.CrudRepository;
import com.braintobytes.finance.data.Currency;
public interface CurrencyRepository extends CrudRepository<Currency, Integer> {
}
Woah!

Java. Spring boot. Application startup failed

I'm trying to learn Spring Boot on my own. I use Maven and have created spring boot application with Tomcat container. When I use mvn spring-boot:run command to run the app it works fine. But when I start my app with ApplicationLoader class it gives me an error. Also, when I use ARC it gives me error 404 not found.
Of course, I understand that there's something wrong with my ApplicationLoader class, but I can't understand what exactly I should change to make it work. Your help is highly appreciated!
Application loader
package com.boris2barak.samplemvc.app;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.context.web.SpringBootServletInitializer;
import org.springframework.context.annotation.ComponentScan;
#SpringBootApplication
public class ApplicationLoader extends SpringBootServletInitializer {
#Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(ApplicationLoader.class);
}
public static void main(String[] args) throws Exception {
SpringApplication.run(ApplicationLoader.class, args);
}
}
Controller
package com.boris2barak.samplemvc.app;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
#Controller
public class myFirstController {
#RequestMapping("/temperature")
public String whatIsTheWeather(Model model, #RequestParam(value="city", required=false, defaultValue="World") String city) {
model.addAttribute("city", city);
WeatherApp data = new WeatherApp();
return data.getTemperatureForCity(city);
}
}

And the mistake looks like that:
objc[1937]: Class JavaLaunchHelper is implemented in both /Library/Java/JavaVirtualMachines/jdk1.8.0_131.jdk/Contents/Home/bin/java (0x1043444c0) and /Library/Java/JavaVirtualMachines/jdk1.8.0_131.jdk/Contents/Home/jre/lib/libinstru ment.dylib (0x1053b54e0). One of the two will be used. Which one is undefined.

Process finished with exit code 1

From the stack trace it's clear that the problem is java.lang.NoClassDefFoundError: javax/servlet/ServletContext means the class is not in the CLASSPATH, which is present in the tomcat jars which is part of spring-boot-starter-tomcat dependencies.
So to make it work with spring boot standalone war/fat jar the spring-boot-starter-tomcat dependency should be in compile scope.
But if you want to deploy in to a java container like tomcat which will have the servlet classes in the container itself so you have keep the spring-boot-starter-tomcat in provided scope.
The best way to handle is create two maven profiles and in one keep the spring-boot-starter-tomcat in compile scope and in another profile in provided scope.

You need to change the SpringBoot main class ApplicationLoader with this class that provided
#SpringBootApplication(scanBasePackages = "com.boris2barak")
public class ApplicationLoader{
public static void main(String[] args) {
SpringApplication.run(ApplicationLoader.class, args);
}
}
