# **1.application.yml配置** #

#thymeleaf模板配置
    spring:
       thymeleaf:
          prefix: classpath:/templates/
          suffix: .html
          cache: false #热部署文件,false页面不产生缓存,及时更新,true开启缓存
       messages:
        basename: messages/demo #指定外部属性文件位置

# **2.properties文件** #

# ![20190222152016901.png][] #

demo\_en\_US.properties

global.welcome=welcome~!xiaoming

demo\_zh\_CN.properties

global.welcome=欢迎，小明

# 3.TemplateResolver实现语言区域解析器 #

import java.util.Locale;
    
    import javax.servlet.http.HttpServletRequest;
    import javax.servlet.http.HttpServletResponse;
    import javax.servlet.http.HttpSession;
    
    import org.springframework.stereotype.Component;
    import org.springframework.web.servlet.LocaleResolver;
    import org.thymeleaf.util.StringUtils;
    
    @Component
    public class TemplateResolver implements LocaleResolver {
    	
         @Override
         public Locale resolveLocale(HttpServletRequest request) {
            Locale locale = Locale.getDefault();//默认
            String l = request.getParameter("language");
            HttpSession session = request.getSession();
            if(!StringUtils.isEmpty(l)){
               String[] split = l.split("_");
               locale = new Locale(split[0],split[1]);
               session.setAttribute("language", locale);
            }else {
               Object lang = session.getAttribute("language");
               if(lang==null) {
                  session.setAttribute("language", locale);
               }else {
                  locale = (Locale) lang;
               }
            }
            return locale;
         }
    
         @Override
         public void setLocale(HttpServletRequest request, HttpServletResponse response, Locale locale) {
    		// TODO Auto-generated method stub
          }
    }

# 4.语言区域解析器配置springmvc容器内 #

package priv.gitonlie.thymeleaf.configure;
    
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.context.annotation.Bean;
    import org.springframework.context.annotation.Configuration;
    import org.springframework.web.servlet.LocaleResolver;
    import org.springframework.web.servlet.config.annotation.WebMvcConfigurationSupport;
    
    @Configuration
    public class TemplateConfigurerAdapter extends WebMvcConfigurationSupport  {
    	
        @Autowired
        private TemplateResolver resolver;
    	
        @Bean
        public LocaleResolver localeResolver(){
            return resolver;
        }
    }

# 5.新建Controller #

@Controller
    public class DemoController {
    	
    	@RequestMapping("index")
    	public String index() {
    		
    		return "index";		
    	}
    }

# 6.新建index.html #

<!DOCTYPE html>
    <html xmlns:th="http://www.thymeleaf.org">
    <head>
    <meta charset="UTF-8">
    <title>Thymeleaf Demo演示页面</title>
    </head>
    <body>
    	<a href="" th:href="@{/index(language='zh_CN')}">中文</a><br/>
    	<a href="" th:href="@{/index(language='en_US')}">English</a><br/>
    	<p th:text="#{global.welcome}">welcome to my demo page</p>
    </body>
    </html>
