SpringMvc的簡單入門（三）之國際化

一.視圖解析

1.在mvc-servlet.xml中配置視圖解析器

 
  <!-- 視圖解析器 -->
  <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
  	<property name="prefix" value="/"></property>
  	<property name="suffix" value=".jsp"></property>
  </bean>

訪問的jsp頁面不用再加.jsp

@RequestMapping(value="/re",method=RequestMethod.POST)
	public String quert(@ModelAttribute("user") @Valid Userin user,BindingResult error){

		return "less04/re";
	}

二.國際化

1.在spring.xml配置國際化的設計

<?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:tx="http://www.springframework.org/schema/tx"
	xmlns:aop="http://www.springframework.org/schema/aop"


	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.2.xsd
	http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.2.xsd
	http://www.springframework.org/schema/tx  http://www.springframework.org/schema/tx/spring-tx-4.1.xsd
	http://www.springframework.org/schema/aop  http://www.springframework.org/schema/aop/spring-aop-4.2.xsd
	
	">


	<!-- 國際化 -->
	<bean id="messageSource" class="org.springframework.context.support.ResourceBundleMessageSource">
		<property name="basename" value="/springmvc/less04/resource/my"></property>
	</bean>
	
</beans>

二.創建國際化語言

username=username
password=password
repassword=repassword
age=age
phone=phone
dob=data
email=email
register=register
userError=The user name cannot be empty
pwd=Password cant be empty
repwd=can not be empty
pho=The phone number must be eleven
ag=Age cannot be empty
ag1=Age must be greater than 1
ag2=Age must be less than 100
data=Time format error

2.頁面，國際化需要<%@taglib uri="http://www.springframework.org/tags" prefix="f"%>標籤 code配置的資源的鍵

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%@taglib uri="http://www.springframework.org/tags/form" prefix="form"%>
<%@taglib uri="http://www.springframework.org/tags" prefix="f"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

        /**
        var name=document.getElementsByName("name")[0].value;
        if(name==null || name==""){
            alert("用戶名不能爲空");
        	return;
        }
        var password=document.getElementsByName("password")[0].value;
        var repassword=document.getElementsByName("repassword")[0].value;
        if(password!=repassword){
            alert("兩次輸入密碼不一致");
        	return;
        }
        **/
      	document.forms[0].submit();
      }
   
   </script>
  </head>
  
  <body >
  <div style="margin-top:82px;text-align: center;">


  	<a href="${pageContext.request.contextPath}/mid?a=zh_CN">中文</a><a href="${pageContext.request.contextPath}/mid?a=en_GB">English</a>
     <form action="<%=path %>/myreg" method="post"> 
         <f:message code="username"></f:message> :<input type="text" name="name"/>*
         <font color=red><form:errors path="user.name"></form:errors></font>

         <font color=red><form:errors path="user.repassword"></form:errors></font>
         <br/>
         <f:message code="email"></f:message> :<input type="text" name="email"/>*
         <font color=red><form:errors path="user.email"></form:errors></font>

         <font color=red><form:errors path="user.phone"></form:errors></font>
         <br/>
        <f:message code="dob"></f:message><input type="text" name="dob"/>*
         <font color=red><form:errors path="user.dob"></form:errors></font>
         <br/>      
   <!-- 時間 輸入格式  yyyy-MM-dd -->     
   <!-- 網址  http://www.baidu.com   http://ip：端口/ -->
        <button οnclick="checkSubmit()"><f:message code="register"></f:message> </button>
     </form><br/>
 	</div>
  </body>
</html>

3.在mvc-servlet.xml中配置獲取本地資源

 <!-- 該攔截器用於攔截URL上參數  只是當jsp經過action之後 纔會將當前國家和語言存儲在session 同事從session中獲取-->
  <mvc:interceptors>
  	<bean id="localeChangeInterceptor" class="org.springframework.web.servlet.i18n.LocaleChangeInterceptor">
  	<!-- 沒傳就讀瀏覽器的 -->
  	<property name="paramName" value="a"></property>
  	</bean>
  	
  </mvc:interceptors>
  <!-- 參數需要被臨時存儲在某個地方 當用戶再次訪問使用之前設置的參數 -->
  <bean id="localeResolver" class="org.springframework.web.servlet.i18n.SessionLocaleResolver">
  </bean>

國際化驗證

<!-- 將springmvc註解的action交給springmvc處理 國際化驗證需要配置validator-->
  <mvc:annotation-driven  validator="localValidatorFactoryBean">
  	<mvc:message-converters>
<bean id="localValidatorFactoryBean" class="org.springframework.validation.beanvalidation.LocalValidatorFactoryBean">
  	<property name="validationMessageSource" ref="messageSource"></property>
  </bean>
