SpringBootStart

package com.test;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;

@SpringBootApplication
@ComponentScan(basePackages = {"com.test.controller*"})
public class SpringBootStart
{
    public static void main(String[] args)
    {
        SpringApplication.run(SpringBootStart.class, args);
    }

}

　　

StartMainController

package com.test.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

@Controller
public class StartMainController
{
    @RequestMapping("/12")
    @ResponseBody
    public String home12()
    {
        return "hello---12";
    }


    @RequestMapping("/123")
    @ResponseBody
    public String home123()
    {
        return "hello---123";
    }


}
