Springboot学习笔记（一）

注意第一个Helloworld项目：浏览发送/hello请求，响应hello，SpringBoot 2

原始SSM:MVC麻烦

1.创建Maven工程

2.引入依赖

 
    
        org.springframework.boot
        spring-boot-starter-parent
        2.3.4.RELEASE
    

 
        
        
            org.springframework.boot
            spring-boot-starter-web
        
 

3.创建主程序

package com.cxy.boot;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

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

4.编写业务

package com.cxy.boot.controller;

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

//@ResponseBody
//@Controller
@RestController
public class HelloController {
    @ResponseBody
    @RequestMapping("/hello")//映射请求
    public String handle01(){
        return "Hello Spring boot2!";
    }
}

5.测试;运行main方法

6.简化配置：application.properties

7.简化部署：打成jar包，直接执行

    
        
            
                org.springframework.boot
                spring-boot-maven-plugin
            
        
    

注意取消CMD的快速依赖
