一、 SPRING支持的GENERAL TAG LIBRARY

二、用<s:message>和ReloadableResourceBundleMessageSource实现国际化

1.配置ReloadableResourceBundleMessageSource,它能it has the ability to reload message properties without recompiling or restarting the application.

 package spittr.web;

 import org.springframework.context.MessageSource;

 import org.springframework.context.annotation.Bean;

 import org.springframework.context.annotation.ComponentScan;

 import org.springframework.context.annotation.Configuration;

 import org.springframework.context.support.ReloadableResourceBundleMessageSource;

 import org.springframework.web.servlet.ViewResolver;

 import org.springframework.web.servlet.config.annotation.DefaultServletHandlerConfigurer;

 import org.springframework.web.servlet.config.annotation.EnableWebMvc;

 import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;

 import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;

 import org.springframework.web.servlet.view.InternalResourceViewResolver;

 @Configuration

 @EnableWebMvc

 @ComponentScan("spittr.web")

 public class WebConfig extends WebMvcConfigurerAdapter {

   @Bean

   public ViewResolver viewResolver() {

     InternalResourceViewResolver resolver = new InternalResourceViewResolver();

     resolver.setPrefix("/WEB-INF/views/");

     resolver.setSuffix(".jsp");

     return resolver;

   }

   @Override

   public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) {

     configurer.enable();

   }

   @Override

   public void addResourceHandlers(ResourceHandlerRegistry registry) {

     // TODO Auto-generated method stub

     super.addResourceHandlers(registry);

   }

   @Bean

   public MessageSource messageSource() {

     ReloadableResourceBundleMessageSource messageSource =

         new ReloadableResourceBundleMessageSource();

     //messageSource.setBasename("file:///Users/habuma/messages");

     //messageSource.setBasename("messages");

     messageSource.setBasename("classpath:messages");

     messageSource.setCacheSeconds(10);

     return messageSource;

   }

 }

(1)路径有3种形式

application路径：没有前缀

classpath:"classpath:xxx"

系统路径:"file:///Users/habuma/messages"

(2)还有另一种MessageResource，要重载资源文件要重启应用

 @Bean

 public MessageSource messageSource() {

     ResourceBundleMessageSource messageSource = new ResourceBundleMessageSource();

     messageSource.setBasename("messages");

     return messageSource;

 }

2.编写资源文件，放到合适的路径

(1)默认文件messages.properties

 spitter.welcome=Welcome to Spitter\!

(2)客户端语言是中文时messages_zh_CN.properties

spitter.welcome=\u6B22\u8FCE

3.view层显示

 <%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>

 <%@ taglib uri="http://www.springframework.org/tags" prefix="s" %>

 <%@ page session="false" %>

 <%@ page contentType="text/html;charset=utf-8" %>

 <html>

   <head>

     <title>Spitter</title>

     <link rel="stylesheet"

           type="text/css"

           href="<c:url value="/resources/style.css" />" >

   </head>

   <body>

     <s:message code="spitter.welcome" text="Welcome" />

   </body>

 </html>
