示例【基于HttpSession的国际化实现】
创建login.jsp
<%@ page language="java" contentType="text/html; charset=utf-8"
pageEncoding="utf-8"%>
<%@ taglib prefix="form" uri="http://www.springframework.org/tags/form"%>
<%@ taglib prefix="spring" uri="http://www.springframework.org/tags"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title><spring:message code="title"></spring:message></title>
</head>
<body>
<a href="loginForm?request_locale=zh_CN" target="_blank" rel="external nofollow" >中文</a> | <a href="loginForm?request_locale=en_US" target="_blank" rel="external nofollow" >英文</a>
<form:form method="post" action="login">
<table>
<tr>
<td><spring:message code="userName"></spring:message></td>
<td><form:input path="userName"/></td>
</tr>
<tr>
<td><spring:message code="passWord"></spring:message></td>
<td><form:password path="passWord"/></td>
</tr>
<tr>
<td></td>
<td><input type="submit" value="<spring:message code="submit"></spring:message>"></td>
</tr>
</table>
</form:form>
</body>
</html>
配置springmvc-config.xml

<!-- 使用注解驱动 -->

创建UserController
package com.controller;
import java.util.Locale;
import javax.servlet.http.HttpServletRequest;
import org.springframework.context.i18n.LocaleContextHolder;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.i18n.SessionLocaleResolver;
import com.po.User;
@Controller
public class UserController {
@RequestMapping("/loginForm")
public String loginForm(String request_locale,Model model,
HttpServletRequest request) {
System.out.println(request_locale);
if(request_locale!=null) {
//设置中文
if(request_locale.equals("zh_CN")) {
Locale locale=new Locale("zh","CN");
request.getSession().setAttribute(SessionLocaleResolver.LOCALE_SESSION_ATTRIBUTE_NAME, locale);
}
//设置英文
else if(request_locale.equals("en_US")) {
Locale locale=new Locale("en","US");
request.getSession().setAttribute(SessionLocaleResolver.LOCALE_SESSION_ATTRIBUTE_NAME, locale);
}
}
//使用之前的语言环境
else {
request.getSession().setAttribute(SessionLocaleResolver.LOCALE_SESSION_ATTRIBUTE_NAME, LocaleContextHolder.getLocale());
}
User user=new User();
model.addAttribute("command",user);
return "login";
}
}
启动Tomcat访问http://localhost:8080/spring/loginForm
控制台输出
