Spring MVC国际化

痛定思痛。 2022-05-16 12:09 243阅读 0赞

**示例：基于浏览器请求的国际化实现**

创建资源文件**message\_en\_US.properties**

title=login page  
userName=userName:  
passWord=passWord:  
submit=submit  
welcom=welcom \{0\}  
name=administrator

创建资源文件**message\_zh\_CN.properties**

title=登录  
userName=用户名:  
passWord=密码:  
submit=提交  
welcom=欢迎 \{0\}  
name=管理员

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>
    	<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>

接下来在**springmvc-config.xml**配置文件中加载国际化资源文件

<?xml version="1.0" encoding="UTF-8"?>
    <beans xmlns="http://www.springframework.org/schema/beans"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xmlns:p="http://www.springframework.org/schema/p"
        xmlns:context="http://www.springframework.org/schema/context"
        xmlns:mvc="http://www.springframework.org/schema/mvc"
        xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
            http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.1.xsd
            http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.1.xsd">
    
    <mvc:annotation-driven />
    
    <context:component-scan base-package="com.*" />
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
    	<property name="prefix" value=""></property>
    	<property name="suffix" value=".jsp" />
    </bean>
    <bean id="messageSource" class="org.springframework.context.support.ResourceBundleMessageSource"
    p:basenames="message"/>
    </beans>

创建**UserController**

package com.controller;
    import javax.servlet.http.HttpServletRequest;
    
    import org.springframework.stereotype.Controller;
    import org.springframework.ui.Model;
    import org.springframework.web.bind.annotation.ModelAttribute;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.servlet.support.RequestContext;
    
    import com.po.User;
    @Controller
    public class UserController {
    	@RequestMapping("/loginForm")
    	public String loginForm(Model model) {
    		User user=new User();
    		model.addAttribute("command",user);
    		return "login";
    	}
    	@RequestMapping("/login")
    	public String login(@ModelAttribute User user,Model model,
    			HttpServletRequest request) {
    		if(user.getUserName()!=null&&user.getUserName().equals("admin")&&
    				user.getPassWord()!=null&&user.getPassWord().equals("123")) {
    			RequestContext requestContext=new RequestContext(request);
    			String name=requestContext.getMessage("name");
    			user.setName(name);
    			model.addAttribute("user",user);
    			return "success";
    		}return "error";			
    	}
    }

创建**success.jsp**

<%@ page language="java" contentType="text/html; charset=utf-8"
        pageEncoding="utf-8"%>
    <%@ taglib prefix="spring" uri="http://www.springframework.org/tags"%>
    <%@taglib prefix="c" uri="http://java.sun.com/jstl/core" %>
    <!DOCTYPE html>
    <html>
    <head>
    <meta charset="utf-8">
    <title>success</title>
    </head>
    <body>
    	<spring:message code="welcom" arguments="${requestScope.user.name }"></spring:message>
    </body>
    </html>

启动Tomcat访问**[http://localhost:8080/spring/loginForm][http_localhost_8080_spring_loginForm]（默认语言：简体中文）**
