Spring Internationalization
To write an application that supports multiples languages, you need to add the following code in your dispatcher.
1. At first message resources
<bean id="messageSource" class="org.springframework.context.support.ReloadableResourceBundleMessageSource"> <property name="basename" value="/WEB-INF/locale/message" /> <property name="defaultEncoding" value="UTF-8" /> </bean>
2. Add the LocaleChangeInterceptor as
<mvc:interceptors> <bean class="org.springframework.web.servlet.i18n.LocaleChangeInterceptor" p:paramName="locale" /> </mvc:interceptors>
3. add the SessionLocaleResolver
<bean id="localeResolver" class="org.springframework.web.servlet.i18n.SessionLocaleResolver"> <property name="defaultLocale" value="en_ES" /> </bean>
4. change the character encoding of your page
<%@ page pageEncoding="UTF-8" contentType="text/html; charset=UTF-8"%> and include the message tag as
<%@ taglib prefix="message" uri="http://www.springframework.org/tags"%>
5. Replace all labels as
<message:message code="student.roll.no" />
A typical JSP page will look as follows
<%@ page pageEncoding="UTF-8" contentType="text/html; charset=UTF-8"%>
<%@ taglib prefix="form" uri="http://www.springframework.org/tags/form"%>
<%@ taglib prefix="message" uri="http://www.springframework.org/tags"%>
<html>
<head>
<title>Please Change Language Here</title>
<script type="text/javascript">
function changeLanguage() {
var lang = document.getElementById("locale");
self.location = "load-form?locale=" + lang.value;
}
</script>
</head>
<body>
<br />
<br />
<table align="center" cellpadding="5" cellspacing="5">
<tr>
<td><form:form action="process-form" commandName="sampleForm"
method="POST" enctype="multipart/form-data">
<table align="center">
<tr>
<td><message:message code="student.roll.no" /></td>
<td><form:input path="rollNo" /></td>
</tr>
<tr>
<td><message:message code="student.name" /></td>
<td><form:input path="name" /></td>
</tr>
<tr>
<td><message:message code="student.address" /></td>
<td><form:input path="address" /></td>
</tr>
<tr>
<td align="center" colspan="2"><input type="submit"
value="Process" /></td>
</tr>
</table>
</form:form></td>
<td>
<table>
<form:form action="load-form" method="get" commandName="languageForm">
<tr>
<td><form:select path="locale" onchange="changeLanguage()">
<form:options items="${languages}" itemLabel="langName"
itemValue="value" />
</form:select></td>
</tr>
</form:form>
</table>
</td>
</tr>
</table>
</body>
</html>
