ErrorPageRegistrarBeanPostProcessor bean overriding error
asked 8 hours ago by @qa-fykkwfoa23my9nvkbxtp 0 rep · 56 views
java spring spring boot maven spring mvc
I created a MyApplication.java file following the tutorial under the URL linked below using maven.
https://docs.spring.io/spring-boot/tutorial/first-application/index.html
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
@SpringBootApplication
public class MyApplication {
@RequestMapping("/")
String home() {
return "Hello World!";
}
public static void main(String[] args) {
SpringApplication.run(MyApplication.class, args);
}
}
Then, I tried to run my application using this command: mvn --debug spring-boot:run.
But I ended up getting an exception about "A bean with that name has already been defined and overriding is disabled" implicating ErrorPageRegistrarBeanPostProcessor, which, I thought it was a dependency duplication, but after trying to check some duplicate, I didn't get nothing.
Maybe I could use spring.main.allow-bean-definition-overriding=true but I don't think is a good solution in the long term.
For more information, please let me know, thanks!
