Java秒杀系统项目环境搭建一（Spring Boot）

一，新建maven project

二、导包

在pom.xml中添加，如下图：

相关代码请查看https://projects.spring.io/spring-boot/官网

以下是环境配置的所有代码

package cn.tedu.miaosha.controller;



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

import cn.tedu.miaosha.result.CodeMsg;
import cn.tedu.miaosha.result.Result;

@Controller
@RequestMapping("/demo")
public class DemoController {
	@RequestMapping("/")
    @ResponseBody
    String home() {
        return "Hello World!";
    }
				//1.rest api json输出2.页面
	
	@RequestMapping("/hello")
    @ResponseBody
    public Result<String> hello() {
		return Result.success("hello wsy");
        //return new Result(0,"success","hello,wsy");
    }
	@RequestMapping("/helloError")
    @ResponseBody
    public Result<String> helloError() {
		return Result.error(CodeMsg.SERVER_ERROR);
//		 return new Result(500102,"xxx");
//		 return new Result(500101,"xxx");
//        return new Result(500100,"session失败");
    }
	@RequestMapping("/thymeleaf")
    public String  thymeleaf(Model model) {
 		model.addAttribute("name", "wsy");
 		return "hello";
    }
