# spring boot web开发（1）构建项目 #

## 1、构建项目 ##

1.  去 https://start.spring.io/ 下载基础项目
2.  在pom.xml 添加 web 依赖

<dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>

*  效果如下

<?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>
    	<parent>
    		<groupId>org.springframework.boot</groupId>
    		<artifactId>spring-boot-starter-parent</artifactId>
    		<version>2.1.7.RELEASE</version>
    		<relativePath/> 
    	</parent>
    	<groupId>com.learn</groupId>
    	<artifactId>first</artifactId>
    	<version>0.0.1-SNAPSHOT</version>
    	<name>first</name>
    	<description>Demo project for Spring Boot</description>
    
    	<properties>
    		<java.version>1.8</java.version>
    	</properties>
    
    	<dependencies>
    		<dependency>
    			<groupId>org.springframework.boot</groupId>
    			<artifactId>spring-boot-starter</artifactId>
    		</dependency>
    		
    		<dependency>
    			<groupId>org.springframework.boot</groupId>
    			<artifactId>spring-boot-starter-web</artifactId>
    		</dependency>
    
    		<dependency>
    			<groupId>org.springframework.boot</groupId>
    			<artifactId>spring-boot-starter-test</artifactId>
    			<scope>test</scope>
    		</dependency>
    	</dependencies>
    
    	<build>
    		<plugins>
    			<plugin>
    				<groupId>org.springframework.boot</groupId>
    				<artifactId>spring-boot-maven-plugin</artifactId>
    			</plugin>
    		</plugins>
    	</build>
    
    </project>

1.  Application.java 同级 新建 controller/HomeController.java

//换自己的包名
    package com.learn.first.controller;
    
    import org.springframework.web.bind.annotation.*;
    
    @RestController
    public class HomeController{
    
        @RequestMapping("/")
        public String Home(){
            return "First Spring boot app";
        }
    
    }

最后文件如下：

1.  运行 Application.java java文件
2.  打开浏览器，http：//127.0.0.1:8080,输出 First Spring boot app
