我试图通过部署一个简单的动态Web项目来了解spring框架中的国际化概念（I18N）。我遇到了一个无法解决的问题。以下是使用的jar文件：
*commons-logging.jar
*org.springframework.asm-3.0.1.RELEASE.jar
*org.springframework.asm-sources-3.0.1.RELEASE.jar
*org.springframework.beans-3.0.1.RELEASE.jar
*org.springframework.beans-sources-3.0.1.RELEASE.jar
*org.springframework.context-3.0.1.RELEASE.jar
*org.springframework.context-sources-3.0.1.RELEASE.jar
*org.springframework.core-3.0.1.RELEASE.jar
*org.springframework.core-sources-3.0.1.RELEASE.jar
*org.springframework.expression-3.0.1.RELEASE.jar
*org.springframework.expression-sources-3.0.1.RELEASE.jar
以下是属性文件：
Data_ka.properties
label=ಹೆಸರು
Data_hi.properties
label=नाम्
XML文件：
spring.xml
<!-- spring - I18N deomo -->
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN 2.0//EN"
"http://www.springframework.org/dtd/spring-beans-2.0.dtd">
<beans>
<bean id="messageSource" class="org.springframework.context.support.ResourceBundleMessageSource">
<property name="basename" value="resources/Data" />
</bean>
</beans>
JSP文件：
的index.jsp
<%@page import="org.springframework.context.support.ClassPathXmlApplicationContext"%>
<%@page import="org.springframework.context.ApplicationContext"%>
<%@page import="java.util.Locale"%>
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<%
String lang= request.getHeader("accept-language");
Locale locale = new Locale(lang);
ApplicationContext ap = new ClassPathXmlApplicationContext("resources/spring.xml");
String value = ap.getMessage("label",null,locale);
%>
<form action="./hello">
<%= value %> :<input type="text" name="name" />
<input type="submit" value="submit">
</form>
我在控制台中收到错误如下：

答案 0 :(得分：1)
Locale locale = new Locale("lang");
应该是
Locale locale = new Locale(lang);
没有引号
