启动java类：

package com.bee.sample.ch1;

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

@SpringBootApplication
public class Ch1Application {
    public static void main(String[] args) {
        SpringApplication.run(Ch1Application.class);
    }
}

controller类：

package com.bee.sample.ch1.controller;

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

@Controller
public class HelloworldController {
    @RequestMapping("/sayhello.html")
    public @ResponseBody
    String say() {
        return "hello spring boot---";
    }
}

rest风格：

package com.bee.sample.ch1.controller;

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

@RestController
public class UserReditRestController {
    @RequestMapping(value = "/usercredit/{id}")
    public String getCreditLevel(@PathVariable String id) {
        return id;
    }
}
