Spring boot 3.0.1 application not running on tomcat9 external server - java

When using my Eclipse's Tomcat9 server (v9.0.62), my "application" runs normally.
Once deployed on my production server however (v9.0.43), 404 is returned.
No stacktraces are being logged by Tomcat.
Both servers use OpenJDK17 as JDK.
This problem does not happen when using versions of Spring < 6.

Expected (Eclipse's server):
Found (Production server):
To pinpoint the problem (as my project is rather large), I reproduced the issue with a simple app based on Spring Initializr.
I attempted tweaking the pom.xml to no avail.

Spring boot 3 requires at least JDK17 and Tomcat 10 due to the package renaming from javax to jakarta.
Tomcat 9 does not work with jakarta packages which were changes introduced in Spring 6/Spring boot 3.
If you want to stay on Tomcat 9 you will need to downgrade to Spring boot version 2.x.x, any Spring boot 3 version will require Tomcat upgrade to version 10.

When I run this commands locally - it works. When it executes on CI - it fails. What I tried to fix:
Run java -jar target/selenium.jar & command on the "Start" step
Run mvn spring-boot:run & command instead of "Build jar" and "Start" steps
Run nohup mvn spring-boot:run & command instead of "Build jar" and "Start" steps
Add sleep 120 step after the "Start" step
Could you please advise me what I am doing wrong?
Pretty sure you are curl'ing before server even started, so try to wait for server to start with
- run:
name: wait
command: sleep 10
Moved to a gitlab CI, the problem is not actual anymore.

Does Spring Boot allow loading external configuration from hidden folders?

So, I created an external configuration file named mystoreroom.yml in "/home/ivan/.config/spring-projects" directory, and I tried specifying its location when launching using the following command:
ivan#IVAN-LAPTOP:~/Projects/Java/my-storeroom$ mvn spring-boot:run -D spring-boot.run.arguments=--spring.config.location=/home/ivan/.config/spring-projects/mystoreroom.yml
After doing that I got an error:

Then I moved mystoreroom.yml to "/home/ivan" directory and tried again:
ivan#IVAN-LAPTOP:~/Projects/Java/my-storeroom$ mvn spring-boot:run -D spring-boot.run.arguments=--spring.config.location=/home/ivan/mystoreroom.yml
This time everything was fine and /foo endpoint successfully printed "bar"
Am I doing something wrong? Or is it suppose to work like that?
Here's the code that I'm using:

I think I stumbled across the same problem. In Spring Boot 2.3.4 the "." in the path was not a problem yet. Since 2.3.5 is released, configurations under "hidden" folders are no longer found. In my case these are not external, rather configurations in the classpath as they are found unpackaged while building. In my mixed maven build environment I have "target" and ".target". The last one is causing problems since 2.3.5. Based on your description, I suspect that this is a new bug.
Bug / Issue 23983

Java Spring with swagger2 not starting server

Hi,
I'm trying to create a Java Spring web application for university classes. I created the Rest controller class connected to two service classes. The services classes are connected to the database via JPA. When I got rid of the errors related to the build problem, I decided to check if everything is correctly visible in swagger. And here the problem arises because despite creating the configuration file the server does not start. The application compiles correctly but the tomcat server does not appear and it is not possible to connect to the server via localhost: 8080. If there were any error, I would manage, but in the console everything looks fine, or I just think so.
Rest Controller class:
#RestController
public class JDBCController {
#Autowired
private IDelegationService delegationService;
#Autowired
private IUserService userService;
#RequestMapping(value = "/registerUser", method = RequestMethod.POST)
#ResponseBody
public void registerUser(#ModelAttribute User user) {
userService.save(user);
}
#RequestMapping(value = "/getAllUsers", method = RequestMethod.GET)
#ResponseBody
public List<User> getAllUsers() {
return userService.findAll();
}
#RequestMapping(value = "/changePassword", method = RequestMethod.PUT)
#ResponseBody
public void changePassword(#RequestParam("userId") long userId, #RequestParam("newPassword") String newPassword) {
userService.updatePassword(userId, newPassword);
}
#RequestMapping(value = "/deleteUserById", method = RequestMethod.DELETE)
#ResponseBody
public boolean deleteUserById(#RequestParam("userId") long userId) {
return userService.deleteById(userId);
}
#RequestMapping(value = "/getAllUsersByRoleName", method = RequestMethod.GET)
#ResponseBody
public List<User> getAllUsersByRoleName(#RequestParam("roleName") String roleName) {
return userService.getAllUsersByRoleName(roleName);
}
#RequestMapping(value = "/addDelegation", method = RequestMethod.POST)
#ResponseBody
public void addDelegation(#RequestParam("userId") long userId, #ModelAttribute Delegation delegation) {
delegationService.save(userId, delegation);
}
#RequestMapping(value = "/removeDelegation", method = RequestMethod.DELETE)
#ResponseBody
public boolean removeDelegation(#RequestParam("userId") long userId,
#RequestParam("delegationId") long delegationId) {
if (delegationId != 0L) {
return delegationService.deleteById(delegationId);
} else if (userId != 0L) {
return delegationService.deleteByUser(userId);
}
return false;
}
#RequestMapping(value = "/changeDelegation", method = RequestMethod.PUT)
#ResponseBody
public void changeDelegation(#RequestParam("delegationId") long delegationId,
#ModelAttribute Delegation delegation) {
delegationService.updateDelegation(delegationId, delegation);
}
#RequestMapping(value = "/getAllDelegations", method = RequestMethod.GET)
#ResponseBody
public List<Delegation> getAllDelegations(){
return delegationService.findAll();
}
#RequestMapping(value = "/getAllDelegationsOrderByDateStartDesc", method = RequestMethod.GET)
#ResponseBody
public List<Delegation> getAllDelegationsOrderByDateStartDesc(){
return delegationService.findAllOrderByDateStartDesc();
}
#RequestMapping(value = "/getAllDelegationsByUserOrderByDateStartDesc", method = RequestMethod.GET)
#ResponseBody
public List<Delegation> getAllDelegationsByUserOrderByDateStartDesc(#RequestParam("userId") Long userId){
return delegationService.findByUserOrderByDateStartDesc(userId);
}
}
Swagger config class:
#Configuration
#EnableSwagger2
public class SpringFoxConfig {
#Bean
public Docket mainConfig() {
return new Docket(DocumentationType.SWAGGER_2)
.select().apis(RequestHandlerSelectors.any())
.paths(PathSelectors.any())
.build()
.pathMapping("/swagger")
.directModelSubstitute(LocalDate.class, String.class)
.genericModelSubstitutes(ResponseEntity.class);

Thank you in advance for your help.\
EDIT.1
This is how my main method and class look like:
#SpringBootApplication
public class Laboratorium1Application {
public static void main(String[] args) {
SpringApplication.run(Laboratorium1Application.class, args);
}
}
Now, as if thinking about it, something should probably be added here so that the configuration file can be seen.
My project folder:
Only now I noticed that there is no html file. Looking at the examples, I thought that it would generate itself but apparently I was wrong. Someone knows where I can download it from.
You need one additional dependency in your pom.xml file for Spring Boot's (embedded Tomcat) server to start: spring-boot-starter-web Add that and you will be good to go.
<dependency>
<groupId>org.springframework.boot</groupId>

Spring boot : constructor injection with xml gives "there is already n bean method"

I am having difficulty getting constructor injection using xml working. I have two implementations of a base repository class and I would like to use the xml file to specify which of these to use.
If I switch to annotation (put #Primary in one of the implementing classes) then it works but I don't want to have to change each class file just to switch from one repository to another.
What am I doing wrong?
The base class
package com.iznogoud.cinj.repositories;
import java.util.ArrayList;
public abstract class StringRepository {
public abstract ArrayList<String> getStrings();
}
The two implementing classes:
package com.iznogoud.cinj.repositories;
import java.util.ArrayList;
import org.springframework.stereotype.Repository;
#Repository
public class StringRepositoryImplOne extends StringRepository{
public StringRepositoryImplOne() {}
public ArrayList<String> getStrings() {
ArrayList<String> result = new ArrayList<String>();
result.add("One");
result.add("Un");
result.add("Eins");
return result;
}
}
...and...
package com.iznogoud.cinj.repositories;
import java.util.ArrayList;
import org.springframework.stereotype.Repository;
#Repository
public class StringRepositoryImplTwo extends StringRepository{
public StringRepositoryImplTwo() {}
public ArrayList<String> getStrings() {
ArrayList<String> result = new ArrayList<String>();
result.add("Two");
result.add("Deux");
result.add("Zwei");
return result;
}
}
The controller where I want to inject one of the two repositories above:
package com.iznogoud.cinj.controllers;
import java.text.ParseException;
import java.util.ArrayList;
import java.util.List;
import javax.servlet.http.HttpSession;import
org.springframework.http.MediaType;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import com.iznogoud.cinj.repositories.StringRepository;
#RestController
#RequestMapping("/cinj")
public class AController {
private StringRepository repository;
public AController(StringRepository _r) {
repository = _r;
}
#GetMapping(path="/test", produces = MediaType.APPLICATION_JSON_VALUE)
List<String> getTimeSlots(HttpSession _session) throws IllegalArgumentException, ParseException {
ArrayList<String> availableStrings = repository.getStrings();
return availableStrings;
}
}
The Application class
package com.iznogoud.cinj;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ImportResource;
import org.springframework.core.SpringVersion;
#SpringBootApplication
#ImportResource("applicationContext.xml")
public class CinjApplication {
public static void main(String[] args) {
System.err.println("Spring version: " + SpringVersion.getVersion());
SpringApplication.run(CinjApplication.class, args);
}
}
The XML configuration:

If the issue is about the ambigious method in the bean named "acont", maybe you have to name it:
#Controller("/acont")
public class AController {...}
By default the bean is detected by type in spring.
In your case you are injecting directly by abstract class.
private StringRepository repository;
In this case you need to use #Qualifier to indicate which bean you are exactly referring to.
#Repository("ImplTwo)
public class StringRepositoryImplTwo extends StringRepository{
Simillary,
#Repository("ImplOne)
public class StringRepositoryImplOne extends StringRepository{
And update your dependency injection as,
#Qualifier("ImplTwo") // or "ImplOne" as per your requirement
private StringRepository repository;
Or as you are using constructor injection than do following,
private StringRepository repository;
public AController(#Qualifier("ImplTwo") StringRepository _r) {
repository = _r;
}
