spring application - get RequestMapping

Question

file : CourseApiApp.java

package io.javabrains.springbootstarter;


        import org.springframework.boot.SpringApplication;
        import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication

public class CourseApiApp {
    public static void main(String[] args){
        //this is the first step to convert the application into spring app
        SpringApplication.run(CourseApiApp.class,args);

    }
}

File HelloControllerTwo

package io.javabrains.springbootstarter.controller;


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

@RestController
@RequestMapping("/hello")

public class HelloControllerTwo {
    public String sayHi() {
        return "Hi";
    }
}

I have created a very basic spring app to get hi on /hello path. I but I am still getting a fallback /error message on /hello

Could anyone please let me know what am I doing wrong?

Answer 1

Your @RequestMapping annotation should be on your method, not your class. You should also specify a method in your annotation.

Try this:

@RestController
public class HelloController {

    @RequestMapping(value = "/hello", method = RequestMethod.GET)
    public String sayHello() {
        return "Hello";
    }
}
