本文介绍了一个Spring MVC控制器，用于根据用户代理字符串判断客户端设备类型，并据此返回不同的视图页面。该控制器通过解析User-Agent头信息来区分PC端与移动端访问。

package com.zhibo.controller;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;

import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;

import eu.bitwalker.useragentutils.OperatingSystem;
import eu.bitwalker.useragentutils.UserAgent;

@Controller
@RequestMapping("/live")
public class LiveController {
	private static final Log logger = LogFactory.getLog(LiveController.class);


	/**
	 * pc端首页
	 */
	@RequestMapping(value = "/index", produces = "text/html;charset=UTF-8")
	public String index(HttpServletRequest request, ModelMap modelMap) {
		String returnJsp = "";
		try {
			UserAgent userAgent = UserAgent.parseUserAgentString(request.getHeader("User-Agent"));
			OperatingSystem os = userAgent.getOperatingSystem();
			String osType = os.getName();
			logger.info("osType====>" + osType);
			if (osType.contains("Android") || osType.contains("iPhone") || osType.contains("iPad")) {// 移动端
				returnJsp = "live/wap";
			}
			if (osType.contains("Windows")) {// PC端
				returnJsp = "live/index";
			}
		} catch (Exception e) {
			e.printStackTrace();
		}
		return returnJsp;
	}
