Spring Boot with Derby Rest API 404 Error-CodePudding

created simple spring boot rest api with gradle build tool

package com.example.demosb;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class DemosbApplication {

    public static void main(String[] args) {
        SpringApplication.run(DemosbApplication.class, args);
    }   

}

my controller class

package com.example.demosb;

import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class demoSbController {
    
    @GetMapping("/welcome")
    public ResponseEntity<String> welcome() {
        return ResponseEntity.ok("Welcome To demo !");
    }

}

dependencies in build.gradle

implementation 'org.springframework.boot:spring-boot-starter-web'
implementation 'org.springframework.boot:spring-boot-starter-data-jpa'
implementation 'org.springframework.boot:spring-boot-starter-jetty'
runtimeOnly 'org.apache.derby:derby'
developmentOnly 'org.springframework.boot:spring-boot-devtools'
implementation 'org.springframework.boot:spring-boot-starter-security'

on url : http://localhost:8888 a login page is shown where i provide username:user and password is the , which leads to 404 error as there is no request mapping on path "/" that is ok

but for url : http://localhost:8888/welcome , still getting 404 error where expected is response entity json object with message : "Welcome To demo !"

CodePudding user response：

In dependencies added is JPA and Derby. Delete them and see if it works now. The connection to the database must be configured.

CodePudding user response：

it worked for now, will be replying progress on this

in my build.gradle, excluded tomcat related dependency from spring-web dependency and from configurations.all task as wanted to use jetty as embedded server

...
implementation('org.springframework.boot:spring-boot-starter-web')
{
   exclude module: 'spring-boot-starter-tomcat'
}
...
configurations.all {
  exclude module: 'spring-boot-starter-tomcat'
  exclude group: 'org.apache.tomcat'
}
