1.新建maven项目，package方式为war.
使用maven的时候，maven会从仓库中下载依赖的jar包。
新建Maven Project 命名为：SpringBoot 选项如图
修改工程目录，添加源文件夹后目录如下：
2.在pom文件spring boot需要的依赖，配置文件如下：
1 <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 2 xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> 3 <modelVersion>4.0.0</modelVersion> 4 5 <groupId>com.lgp</groupId> 6 <artifactId>SpringBoot</artifactId> 7 <version>0.0.1-SNAPSHOT</version> 8 <packaging>jar</packaging> 9 10 <name>SpringBoot</name> 11 <url>http://maven.apache.org</url> 12 13 <properties> 14 <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> 15 </properties> 16 17 <!-- Inherit defaults from Spring Boot --> 18 <parent> 19 <groupId>org.springframework.boot</groupId> 20 <artifactId>spring-boot-starter-parent</artifactId> 21 <version>1.4.0.BUILD-SNAPSHOT</version> 22 </parent> 23 24 <!-- Add typical dependencies for a web application --> 25 <dependencies> 26 <dependency> 27 <groupId>org.springframework.boot</groupId> 28 <artifactId>spring-boot-starter-web</artifactId> 29 </dependency> 30 <dependency> 31 <groupId>junit</groupId> 32 <artifactId>junit</artifactId> 33 <version>3.8.1</version> 34 <scope>test</scope> 35 </dependency> 36 </dependencies> 37 38 <!-- Package as an executable jar --> 39 <build> 40 <plugins> 41 <!-- <plugin> 42 <groupId>org.springframework.boot</groupId> 43 <artifactId>spring-boot-maven-plugin</artifactId> 44 </plugin> --> 45 46 <!-- Maven Assembly Plugin --> 47 <plugin> 48 <groupId>org.apache.maven.plugins</groupId> 49 <artifactId>maven-assembly-plugin</artifactId> 50 <version>2.4.1</version> 51 <configuration> 52 <!-- get all project dependencies --> 53 <descriptorRefs> 54 <descriptorRef>jar-with-dependencies</descriptorRef> 55 </descriptorRefs> 56 <!-- MainClass in mainfest make a executable jar --> 57 <archive> 58 <manifest> 59 <mainClass>com.lgp.SpringBoot.App</mainClass> 60 </manifest> 61 </archive> 62 63 </configuration> 64 <executions> 65 <execution> 66 <id>make-assembly</id> 67 <!-- bind to the packaging phase --> 68 <phase>package</phase> 69 <goals> 70 <goal>single</goal> 71 </goals> 72 </execution> 73 </executions> 74 </plugin> 75 76 </plugins> 77 </build> 78 79 80 81 <!-- Add Spring repositories --> 82 <!-- (you don‘t need this if you are using a .RELEASE version) --> 83 <repositories> 84 <repository> 85 <id>spring-snapshots</id> 86 <url>http://repo.spring.io/snapshot</url> 87 <snapshots><enabled>true</enabled></snapshots> 88 </repository> 89 <repository> 90 <id>spring-milestones</id> 91 <url>http://repo.spring.io/milestone</url> 92 </repository> 93 </repositories> 94 <pluginRepositories> 95 <pluginRepository> 96 <id>spring-snapshots</id> 97 <url>http://repo.spring.io/snapshot</url> 98 </pluginRepository> 99 <pluginRepository> 100 <id>spring-milestones</id> 101 <url>http://repo.spring.io/milestone</url> 102 </pluginRepository> 103 </pluginRepositories> 104 </project>
3.编辑JAVA代码新建APP.class
1 package com.lgp.SpringBoot;
2
3 import org.springframework.boot.SpringApplication;
4 import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
5 import org.springframework.web.bind.annotation.RequestMapping;
6 import org.springframework.web.bind.annotation.RestController;
7
8 @RestController
9 @EnableAutoConfiguration
10 public class App
11 {
12 @RequestMapping("/h")
13 public String home() {
14 return "Hello";
15 }
16
17 @RequestMapping("/w")
18 public String word() {
19 return "World";
20 }
21
22 public static void main( String[] args )
23 {
24 System.out.println( "Hello World ! App!" );
25 SpringApplication.run(App.class, args);
26 //SpringApplication.run(UserController.class, args);
27 }
28 }
3.编写测试action，此action跟用其他方式创建spring项目里边的action没什么区别。
1 package com.example;
2
3 import org.springframework.boot.SpringApplication;
4 import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
5 import org.springframework.stereotype.Controller;
6 import org.springframework.web.bind.annotation.RequestMapping;
7 import org.springframework.web.bind.annotation.ResponseBody;
8
9 @Controller
10 @EnableAutoConfiguration
11 public class HelloController {
12
13 @RequestMapping("/hello")
14 @ResponseBody
15 String home() {
16 return "Hello ,spring boot!";
17 }
18
19 public static void main(String[] args) throws Exception {
20 SpringApplication.run(HelloController.class, args);
21 //运行之后在浏览器中访问：http://localhost:8080/hello
22 }
23
24 }
4.启动项目，只需要运行上面代码的main方法，运行成功，控制台输出如下

5.在浏览器中访问，如下：
运行App.java 访问 http://localhost:8080/user/12
