PC端和手机端入口一致，跳转不同格式页面的解决方案

如：PC端接口请求后跳转到jsp页面，手机端请求接口后跳转到html页面，两个客户端公用一个入口（index.do）。

// 跳转首页
	@RequestMapping(value = "/index.do", method = RequestMethod.GET)
	public String toIndex(HttpServletRequest req, HttpServletResponse res) {
		if (EquipmentJudgment.JudgeIsMoblie(req)) {
			// 来自移动端访问
			return "redirect:/wap";//重定向到另一个接口(手机端接口入口)
		} else {
			// 来自PC端访问
			return "/index";//跳转到index页面
		}

	}

1. spring-mvc.xml中修改视图解析器，如下：

<!-- 定义HTML文件的位置 -->
	<bean id="htmlviewResolver"
		class="org.springframework.web.servlet.view.InternalResourceViewResolver">
		<property name="viewClass"
			value="com.abc.common.HtmlResourceView" />
		<property name="order" value="0" />
		<property name="prefix" value="/WEB-INF/view/" />
		<property name="suffix" value=".html" />
		<property name="contentType" value="text/html;charset=UTF-8"></property>
	</bean>
	<!-- 定义JSP文件的位置 -->
	<bean id="jspViewResolver"
		class="org.springframework.web.servlet.view.InternalResourceViewResolver">
		<property name="order" value="1" />
		<property name="prefix" value="/WEB-INF/jsp/" />
		<property name="suffix" value=".jsp" />
	</bean>

说明：当接口返回页面时，首先会去找.html页面，找到了就执行完了，找不到就会自动去找.jsp页面。见HtmlResourceView.java 。

所有的页面名字不要重复！

2. 编写类EquipmentJudgment.java（判断是否是手机端）

package com.abc.common;

import javax.servlet.http.HttpServletRequest;

public class EquipmentJudgment {
	public static boolean JudgeIsMoblie(HttpServletRequest request) {
		boolean isMoblie = false;
		String[] mobileAgents = { "iphone", "android", "phone", "mobile", "wap", "netfront", "java", "opera mobi", "opera mini", "ucweb", "windows ce", "symbian", "series",
				"webos", "sony", "blackberry", "dopod", "nokia", "samsung", "palmsource", "xda", "pieplus", "meizu", "midp", "cldc", "motorola", "foma", "docomo", "up.browser",
				"up.link", "blazer", "helio", "hosin", "huawei", "novarra", "coolpad", "webos", "techfaith", "palmsource", "alcatel", "amoi", "ktouch", "nexian", "ericsson",
				"philips", "sagem", "wellcom", "bunjalloo", "maui", "smartphone", "iemobile", "spice", "bird", "zte-", "longcos", "pantech", "gionee", "portalmmm", "jig browser",
				"hiptop", "benq", "haier", "^lct", "320x320", "240x320", "176x220", "w3c ", "acs-", "alav", "alca", "amoi", "audi", "avan", "benq", "bird", "blac", "blaz", "brew",
				"cell", "cldc", "cmd-", "dang", "doco", "eric", "hipt", "inno", "ipaq", "java", "jigs", "kddi", "keji", "leno", "lg-c", "lg-d", "lg-g", "lge-", "maui", "maxo",
				"midp", "mits", "mmef", "mobi", "mot-", "moto", "mwbp", "nec-", "newt", "noki", "oper", "palm", "pana", "pant", "phil", "play", "port", "prox", "qwap", "sage",
				"sams", "sany", "sch-", "sec-", "send", "seri", "sgh-", "shar", "sie-", "siem", "smal", "smar", "sony", "sph-", "symb", "t-mo", "teli", "tim-", "tosh", "tsm-",
				"upg1", "upsi", "vk-v", "voda", "wap-", "wapa", "wapi", "wapp", "wapr", "webc", "winw", "winw", "xda", "xda-", "Googlebot-Mobile" };
		if (request.getHeader("User-Agent") != null) {
			for (String mobileAgent : mobileAgents) {
				if (request.getHeader("User-Agent").toLowerCase().indexOf(mobileAgent) >= 0) {
					isMoblie = true;
					break;
				}
			}
		}
		return isMoblie;
	}
}

3. 编写类spring-mvc.xml 配置中的类HtmlResourceView.java（判断要跳转的页面是否存在）

package com.abc.common;

import java.io.File;
import java.util.Locale;

import org.springframework.web.servlet.view.InternalResourceView;

public class HtmlResourceView extends InternalResourceView {
	@Override
	public boolean checkResource(Locale locale) {
		File file = new File(this.getServletContext().getRealPath("/") + getUrl());
		return file.exists();// 判断该页面是否存在
	}
}
