Finish完项目创建成功

2.配置依赖

1.目录结构

这是项目创建之后得到的文件目录在此之上还有再增加一些目录结构

如下图

2.编辑pom.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

	</build>


</project>

pom.xml文件配置如此

3.编辑application.properties文件

server.port=8080
#服务端口
spring.datasource.url=jdbc:mysql://localhost:3306/springdemo
#链接数据库
spring.datasource.username=root
#用户
spring.datasource.password=123456
#密码
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
        
mybatis.type-aliases-package=com.example.demo.model
#指定bean所在包
mybatis.mapperLocations=classpath:mapper/*.xml
#指定映射文件
spring.mvc.static-path-pattern=static/**
#定义静态文件位置

4.Hello World

1.编写HelloControlller

package com.example.demo.controller;

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

@Controller
@RequestMapping("/")
public class HelloController {
    @RequestMapping("/hello")
    @ResponseBody
    public String hello(){
        return "hello world";
    }
}

2.通过浏览器访问 127.0.0.1:8080/hello
