跟随SpringBoot的文档（http://docs.spring.io/spring-boot/docs/current-SNAPSHOT/reference/htmlsingle/#boot-documentation）学习，前后几章关联才调通代码，煞是痛苦，在这里记录结果，过程隐忍。
一、准备工作
1、根据Maven工程特点，建立文档结果
myFirstProject
+-src
+-main
+-Java
+-resources
+-test
+-java
+-resources
2、再在src/main/java下依次建立文件夹com，example，myFirstProject，可以构成Maven工程包(package)-->com.example.myFirstProject,最后文档结构如图1
图1
3、编制pom.xml,存于myFirstProject文件夹下，与src同级
[html] view plain copy <?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>myFirstproject</artifactId> <version>0.0.1-SNAPSHOT</version> <!-- Inherit defaults from Spring Boot --> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>1.4.0.BUILD-SNAPSHOT</version> </parent> <!-- Add typical dependencies for a web application --> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> </dependencies> <!-- Package as an executable jar --> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> </build> <!-- Add Spring repositories --> <!-- (you don't need this if you are using a .RELEASE version) --> <repositories> <repository> <id>spring-snapshots</id> <url>http://repo.spring.io/snapshot</url> <snapshots><enabled>true</enabled></snapshots> </repository> <repository> <id>spring-milestones</id> <url>http://repo.spring.io/milestone</url> </repository> </repositories> <pluginRepositories> <pluginRepository> <id>spring-snapshots</id> <url>http://repo.spring.io/snapshot</url> </pluginRepository> <pluginRepository> <id>spring-milestones</id> <url>http://repo.spring.io/milestone</url> </pluginRepository> </pluginRepositories> </project> 文档内容从SpringBoot的文档拷贝
4、编制Application.java存于myFirstProject\src\main\java\com\example\myFirstProject下
[java] view plain copy package com.example.myFirstProject; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; @SpringBootApplication public class Application { public static void main(String[] args) { SpringApplication.run(Application.class, args); } } 5、编制Example.java，存于myFirstProject\src\main\java\com\example\myFirstProject下
[java] view plain copy package com.example.myFirstProject; import org.springframework.boot.autoconfigure.EnableAutoConfiguration; import org.springframework.web.bind.annotation.PathVariable; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RestController; @RestController @EnableAutoConfiguration public class Example { @RequestMapping("/") String home() { return "Hello World!"; } @RequestMapping("/hello/{myName}") String index(@PathVariable String myName) { return "Hello "+myName+"!!!"; } } 二、Maven工程导入
1、启动eclipse
1.1、java-->jdk1.7.0_80x64
1.2、maven-->Apache Maven 3.3.3
1.3、Eclipse Java EE IDE for Web Developers. Version: Mars Release (4.5.0)
1.4、为本练习，新建一个workgroup
2、在eclipse中，依次点击file-->import-->Maven-->Existing Maven Projects-->Next-->Browse-->定位到myFirstProject文件夹-->确定--Finish
3、导入结果如图2
图2
三、运行
1、在eclipse的工程myFirstProject上右击鼠标，选择Run as-->Java Application，如图3
2、在select Java Aplication中选择“Application -com.example.myFirstProject”，如图4
图4
3、再次点击“OK”按钮,在Eclipse的Console中开始打印如图5
图5
4、打开浏览器，输入http://localhost:8080，显示如图6
5、在浏览器中,输入http://localhost:8080/hello/SpringBoot
四、后记
痛则不通，通则不痛。这个例子非常之简单，为了这个简单，费事不少。为了这个例子能够成功，最好做以下准备
1、构建本地的Maven伺服，否则速度痛苦
2、Sonatype Nexus尽量和jdk相对应的版本，不要最求最新，否则可能启动不起来。
3、Sonatype Nexus搭建，参考
经过个人测试有效
