Sping RestController not responding to request-CodePudding

I am just trying to implement a sample rest controller on spring boot for learning. When i am sending the request through web browser i am getting a white label error.

My applications context path is set to /learn. Below are my source files, project structure and pom.xml.

TestController.java

package com.practice.learn.controller;

import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
@RequestMapping("/learn")
public class TestController {

    TestController(){
        System.out.println("TestController initialized");
    }
    @GetMapping("/test")
    public String testMethod() {
        System.out.println("Inside test method");
        return "This is sample text";
    }
}

@SpringBootApplication

    public static void main(String[] args) {

server.servlet.context-path=/learn

CodePudding user response：

since you already set the servlet context path as '/learn' in your configuration file, you do not need to add '/learn' again in the RequestMapping in your controller. just remove it and let us know.
