Spring boot for Eclipse 开发指南第一节 快速建立

准备工做1

java version "1.8.0_131"
Java(TM) SE Runtime Environment (build 1.8.0_131-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.131-b11, mixed mode)

准备工做2

Eclipse Java EE IDE for Web Developers.

Version: Neon.1a Release (4.6.1)
Build id: 20161007-1200

该版本集成了MAVEN插件 无需安装

请配置好MAVEN的环境 (部分省略)

 

搭建spring-boot 只需几部 十分简单

1. 新建一个3.0的 Web Pro0ject

File - New - Dynamic Web Project

输入 ProjectName 

Target Runtime 选择 Apache Tomcat 8.5 若是没有就 new 一个

Dynamic Web module version 选择3.0 

Finish

2. 将工程转换为 Maven 工程

右键工程 Configure - Convert to Maven Project

在 GroupId 中输入包名 例如 com.avicsafety.webapp

Finish

在POM.XML中 拷贝如下代码并保存

<?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">

    </parent>

    <!-- Add typical dependencies for a web application -->

                           </goals> 
                           <configuration> 
                               <classifier>exec</classifier> 
                           </configuration> 
                       </execution> 
                    </executions>

			      <target>1.8</target>
			   </configuration>
			</plugin>
		</plugins>
	</build>

</project>

右键工程 - Maven - Update Project 

转换工程结束

 

3. 启用工程

右键工程中的 src - Build Path - Use as Source Folder

展开工程中的 Java Respource 右键 src 选择 New - Class

Package 中输入本身的包名  com.avicsafety.webapp

Name 中输入 MyApplication

Finish

在打开的MyApplication.java 中输入如下代码并保存

package com.avicsafety.webapp;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
@EnableAutoConfiguration
@SpringBootApplication
public class MyApplication {
	 @RequestMapping("/")
	    String home() {
	        return "Hello World!";
	    }
	    public static void main(String[] args) throws Exception {
	        SpringApplication.run(MyApplication.class, args);
	    }
}

右键该文件 选择 Run As - Java Application 

控制台出现 Started MyApplication in 3.096 seconds (JVM running for 3.449) 

恭喜 Spring boot 搭建完毕

 

打开浏览器输入 http://localhost:8080/ 能够看到 Hello World!
