一、 SPRING支持的GENERAL TAG LIBRARY
1.
二、用<s:message>和ReloadableResourceBundleMessageSource實現國際化
1.配置ReloadableResourceBundleMessageSource,它能it has the ability to reload message properties without recompiling or restarting the application.
1 package spittr.web; 2 3 import org.springframework.context.MessageSource; 4 import org.springframework.context.annotation.Bean; 5 import org.springframework.context.annotation.ComponentScan; 6 import org.springframework.context.annotation.Configuration; 7 import org.springframework.context.support.ReloadableResourceBundleMessageSource; 8 import org.springframework.web.servlet.ViewResolver; 9 import org.springframework.web.servlet.config.annotation.DefaultServletHandlerConfigurer; 10 import org.springframework.web.servlet.config.annotation.EnableWebMvc; 11 import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry; 12 import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter; 13 import org.springframework.web.servlet.view.InternalResourceViewResolver; 14 15 @Configuration 16 @EnableWebMvc 17 @ComponentScan("spittr.web") 18 public class WebConfig extends WebMvcConfigurerAdapter { 19 20 @Bean 21 public ViewResolver viewResolver() { 22 InternalResourceViewResolver resolver = new InternalResourceViewResolver(); 23 resolver.setPrefix("/WEB-INF/views/"); 24 resolver.setSuffix(".jsp"); 25 return resolver; 26 } 27 28 @Override 29 public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) { 30 configurer.enable(); 31 } 32 33 @Override 34 public void addResourceHandlers(ResourceHandlerRegistry registry) { 35 // TODO Auto-generated method stub 36 super.addResourceHandlers(registry); 37 } 38 39 @Bean 40 public MessageSource messageSource() { 41 ReloadableResourceBundleMessageSource messageSource = 42 new ReloadableResourceBundleMessageSource(); 43 //messageSource.setBasename("file:///Users/habuma/messages"); 44 //messageSource.setBasename("messages"); 45 messageSource.setBasename("classpath:messages"); 46 messageSource.setCacheSeconds(10); 47 return messageSource; 48 } 49 50 }
(1)路徑有3種形式
application路徑：沒有前綴
classpath:"classpath:xxx"
系統路徑:"file:///Users/habuma/messages"
(2)還有另一種MessageResource，要重載資源文件要重啟應用
1 @Bean 2 public MessageSource messageSource() { 3 ResourceBundleMessageSource messageSource = new ResourceBundleMessageSource(); 4 messageSource.setBasename("messages"); 5 return messageSource; 6 }
2.編寫資源文件，放到合適的路徑
(1)默認文件messages.properties
1 spitter.welcome=Welcome to Spitter\!
(2)客戶端語言是中文時messages_zh_CN.properties
spitter.welcome=\u6B22\u8FCE
3.view層顯示
1 <%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %> 2 <%@ taglib uri="http://www.springframework.org/tags" prefix="s" %> 3 <%@ page session="false" %> 4 <%@ page contentType="text/html;charset=utf-8" %> 5 <html> 6 <head> 7 <title>Spitter</title> 8 <link rel="stylesheet" 9 type="text/css" 10 href="<c:url value="/resources/style.css" />" > 11 </head> 12 <body> 13 <s:message code="spitter.welcome" text="Welcome" /> 14 </body> 15 </html>
