使用maven快速构建一个基于Spring boot的项目，功能是检测访问页面的设备。

# 需要的工具 #

1、maven 3.0+（不会使用的话可以参考[http://blog.csdn.net/u010902721/article/details/51203170][http_blog.csdn.net_u010902721_article_details_51203170]）  
2、文本编辑器。  
3、java 1.8+

# 开始 #

└── src
        └── main
            └── java
                └── hello

在项目根目录下新建pom.xml，内容如下：

<?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">

        <groupId>org.springframework</groupId>

        <dependencies>
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-web</artifactId>
            </dependency>
            <dependency>
                <groupId>org.springframework.mobile</groupId>
                <artifactId>spring-mobile-device</artifactId>
            </dependency>
        </dependencies>
    
        <properties>
            <java.version>1.8</java.version>
        </properties>
    
    
        <build>
            <plugins>
                <plugin>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-maven-plugin</artifactId>
                </plugin>
            </plugins>
        </build>
    
        <repositories>
            <repository>
                <id>spring-releases</id>
                <name>Spring Milestone Repository</name>
                <url>https://repo.spring.io/libs-release</url>
            </repository>
        </repositories>
    
        <pluginRepositories>
            <pluginRepository>
                <id>spring-releases</id>
                <name>Spring Milestone Repository</name>
                <url>https://repo.spring.io/libs-release</url>
            </pluginRepository>
        </pluginRepositories>
    
    </project>

新建src/main/java/hello/DeviceDetectionController.java，代码如下：

package hello;
    
    import org.springframework.mobile.device.Device;
    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.ResponseBody;
    
    @Controller
    public class DeviceDetectionController { 
    
        @RequestMapping("/detect-device")
        public @ResponseBody String detectDevice(Device device) {
            String deviceType = "unknown";
            if (device.isNormal()) {
                deviceType = "normal";
            } else if (device.isMobile()) {
                deviceType = "mobile";
            } else if (device.isTablet()) {
                deviceType = "tablet";
            }
            return "Hello " + deviceType + " browser!";
        }
    
    }

新建src/main/java/hello/Application.java，代码如下：

package hello;
    
    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);
        }
    
    }

命令行转移到项目根目录下，windows下执行以下命令（linux下改一下/）：

mvn package
    mvn java -jar target/gs-device-detection-0.1.0.jar

可以通过浏览器访问 [http://localhost:8080/detect-device][http_localhost_8080_detect-device]，查看结果。如果使用手机或者平板里的浏览器访问时，修改localhost为项目所在机器的IP。
