Springboot系列之——快速搭建一个简单的SpringBoot项目

搭建步骤如下：

这里使用的是新版本的eclipse搭建

1.new 一个Sprintboot工程

next

 finish，sprintboot工程就创建好了,工程目录结构如下

2.配置工程的pom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"
	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>com.example</groupId>
	<artifactId>springboot-web-demo</artifactId>
	<version>0.0.1-SNAPSHOT</version>
	<packaging>jar</packaging>

	<name>springboot-web-demo</name>
	<description>Demo project for Spring Boot</description>

	<parent>
		<groupId>org.springframework.boot</groupId>
		<artifactId>spring-boot-starter-parent</artifactId>
		<version>2.0.4.RELEASE</version>
		<relativePath /> <!-- lookup parent from repository -->
	</parent>

	<properties>
		<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
		<project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
		<java.version>1.8</java.version>
	</properties>

	<dependencies>
		<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>
		<!-- 引入log4j日志依赖 -->
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-log4j</artifactId>
			<version>1.3.8.RELEASE</version>
		</dependency>
		<!-- 热部署 -->
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-devtools</artifactId>
			<!-- optional=true, 依赖不会传递, 该项目依赖devtools; 之后依boot项目的项目如果想要使用devtools, 需要重新引入 -->
			<optional>true</optional>
		</dependency>

	</dependencies>

	<build>
		<plugins>
			<plugin>
				<groupId>org.springframework.boot</groupId>
				<artifactId>spring-boot-maven-plugin</artifactId>
			</plugin>
		</plugins>
	</build>


</project>

这里需要注意的是如果要使我们的热部署生效，还要在我们的application.properties中配置如下内容：

spring.devtools.restart.enabled=true

spring.devtools.restart.additional-paths=src/main/java  #这里是我们热部署重新加载编译的目录

3.创建我们的Action

package com.example.demo;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import com.example.vo.User;

@RestController
public class IndexAction {

	@RequestMapping("/index")
	public User index() {
		User user = new User();
		user.setName("xyp");
		user.setPassWord("123");
		return user;
	}
}

User类如下：

package com.example.vo;

public class User {

	private String name;
	private String passWord;
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public String getPassWord() {
		return passWord;
	}
	public void setPassWord(String passWord) {
		this.passWord = passWord;
	}
	public String toString() {
		return name+":"+passWord;
	}
}

启动SpringbootWebDemoApplication类，springboot项目就跑起来了，效果如下：

总体工程目录如下：
