spring-boot 搭建web项目

一、创建项目或模块

二、导入依赖

<?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"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <groupId>org.example</groupId>
    <artifactId>spirngbootweb</artifactId>
    <version>1.0-SNAPSHOT</version>
    <!--导入spring-boot 启动父类-->
    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.0.1.RELEASE</version>
    </parent>

   <dependencies>
       <!--导入web依赖-->
       <dependency>
           <groupId>org.springframework.boot</groupId>
           <artifactId>spring-boot-starter-web</artifactId>
           <version>2.0.1.RELEASE</version>
       </dependency>
   </dependencies>
</project>

三、配置application.yml

在resource目录下创建application.yml，配置如下信息

server:
  port: 8080
spring:
  application:
    name: spirngbootweb

四、创建启动类

启动类位置要在项目最上层包下

package com;

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

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

五、创建controller

可以将对象自动转换为json字符串

package com.itcast.controller;

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

import java.util.HashMap;
import java.util.Map;

@Controller
public class DemoCotrller1 {

    @RequestMapping("list")
    @ResponseBody
    public Map findList() {


        Map map=new HashMap();
        map.put("nema","张三");
        map.put("age","15");
        map.put("job","it");
        return map;

    }

}
