Eclipse下使用Maven建立简单Springboot程序

1、创建Maven工程

2、编写pom.xml

 <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/maven-v4_0_0.xsd">
   <modelVersion>4.0.0</modelVersion>
   <groupId>com.niiam.ppweb</groupId>
   <artifactId>ppweb</artifactId>
   <packaging>war</packaging>
   <version>0.0.1-SNAPSHOT</version>
   <name>ppweb Maven Webapp</name>
   <url>http://maven.apache.org</url>
 
   <parent>
   <groupId>org.springframework.boot</groupId>
   <artifactId>spring-boot-starter-parent</artifactId>
   <version>1.5.9.RELEASE</version>
   </parent>
 
   <dependencies>
     <dependency>
         <groupId>org.springframework.boot</groupId>
         <artifactId>spring-boot-starter-web</artifactId>
     </dependency>
     <dependency>
       <groupId>junit</groupId>
       <artifactId>junit</artifactId>
       <version>3.8.1</version>
       <scope>test</scope>
     </dependency>
 
   </dependencies>
   <build>
     <finalName>ppweb</finalName>
   </build>
 </project>

编写完后，右键项目选择Maven->Update Project(如项目无报错，则不需要)。创建Java的Source Folder，结构如下图：

解决Eclipse建立Maven项目后无法建立src/main/java资源文件夹的办法

在项目上右键选择properties，然后点击java build path，在Librarys下，编辑JRE System Library，选择workspace default jre就可以了。

测试Springboot

新建类：

 package com.niiam.ppweb;
 
 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
 public class AppleApplication {
   @RequestMapping("/")
      String home() {
          return "Hello World!";
      }
      public static void main(String[] args) {
          SpringApplication.run(AppleApplication.class, args);
      }
 }

右键选择run as->java application
