1:首先在maven添加依赖,(2.0起可用)

<?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 https://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.4.5</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>
    <groupId>com.example</groupId>
    <artifactId>mobile</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <name>mobile</name>
    <description>Demo project for Spring Boot</description>
    <properties>
        <java.version>11</java.version>
    </properties>
    <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>
            <version>2.0.0.M3</version>
        </dependency>

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>
    </dependencies>

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>

    <repositories>
        <repository>
            <id>spring-milestones</id>
            <name>Spring Milestones</name>
            <url>https://repo.spring.io/libs-milestone</url>
            <snapshots>
                <enabled>false</enabled>
            </snapshots>
        </repository>
    </repositories>

</project>

2:添加拦截器配置类

package com.example.mobile;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.mobile.device.DeviceHandlerMethodArgumentResolver;
import org.springframework.mobile.device.DeviceResolverHandlerInterceptor;
import org.springframework.web.method.support.HandlerMethodArgumentResolver;
import org.springframework.web.servlet.config.annotation.InterceptorRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;

import java.util.List;

@Configuration
public class MobileWebMvcConfigurer implements WebMvcConfigurer {

    @Bean
    public DeviceResolverHandlerInterceptor
    deviceResolverHandlerInterceptor() {
        return new DeviceResolverHandlerInterceptor();
    }

    @Bean
    public DeviceHandlerMethodArgumentResolver
    deviceHandlerMethodArgumentResolver() {
        return new DeviceHandlerMethodArgumentResolver();
    }

    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        registry.addInterceptor(deviceResolverHandlerInterceptor());
    }

    @Override
    public void addArgumentResolvers(List<HandlerMethodArgumentResolver> argumentResolvers) {
        argumentResolvers.add(deviceHandlerMethodArgumentResolver());
    }

}

3:编写接口

package com.example.mobile;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.mobile.device.Device;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

@SpringBootApplication
@RestController
public class MobileApplication {

    public static void main(String[] args) {
        SpringApplication.run(MobileApplication.class, args);
    }

    @GetMapping
    public String mobile(Device device) {
        if (device.isMobile()) {
            // 判断设备是否手机端
            // device.getDevicePlatform()获取设备平台,暂时只有IOS,ANDROID,UNKNOWN
            return "Hello " + device.getDevicePlatform() + " mobile user!";
        } else if (device.isTablet()) {
            // 判断设备是否平板端
            // device.getDevicePlatform()获取设备平台,暂时只有IOS,ANDROID,UNKNOWN
            return "Hello " + device.getDevicePlatform() + " tablet user!";
        } else {
            // 其他设备一律判断为电脑端
            return "Hello desktop user!";
        }
    }

}

4:启动Spring Boot,访问 http://localhost:8080 查看效果
