Thymeleaf 模板语言

Thymeleaf内置对象

一：基础对象

1. ctx: the context object
   ctx对象继承org.thymeleaf.context.IContext或者org.thymeleaf.context.IWebContext，取决于当前环境是不是web环境。如果程序集成了spring，那么将会是

org.thymeleaf.spring[3|4].context.SpringWebContext
#org.thymeleaf.context.IContext    
${#ctx.locale}    
${#ctx.variables}    
#org.thymeleaf.context.IWebContext    
${#ctx.applicationAttributes}    
${#ctx.httpServletRequest}    
${#ctx.httpServletResponse}    
${#ctx.httpSession}    
${#ctx.requestAttributes}    
${#ctx.requestParameters}    
${#ctx.servletContext}    
${#ctx.sessionAttributes}

2. vars: the context variables,访问VariablesMap所有上下文中的变量

#org.thymeleaf.context.VariablesMap    
${#vars.get('foo')}    
${#vars.containsKey('foo')}    
${#vars.size()}

3. locale: the context locale, java.util.Locale对象的访问

4. request: (only in Web Contexts) the HttpServletRequest object

5. response: (only in Web Contexts) the HttpServletResponse object

6. session: (only in Web Contexts) the HttpSession object(需要contoller/action(HttpSession session))

7. servletContext: (only in Web Contexts) the ServletContext object

二：web环境对象

1. httpServletRequest :javax.servlet.http.HttpServletRequest对象实例

${#httpServletRequest.getAttribute('foo')}    
${#httpServletRequest.getParameter('foo')}    
${#httpServletRequest.getContextPath()}    
${#httpServletRequest.getRequestName()}

2. httpSession(需要contoller/action(HttpSession session))

${#httpSession.getAttribute('foo')}    
${#httpSession.id}    
${#httpSession.lastAccessedTime}

三：spring环境对象
themes : 提供和“ spring:theme JSP tag.”同样的功能。

${#themes.code('foo')}

四：web环境中访问request/session等属性

1. param :获取请求的参数.

${param.foo} // Retrieves a String[] with the values of request parameter 'foo'        
${param.size()}        
${param.isEmpty()}        
${param.containsKey('foo')}    

2. session:访问session属性

${session.foo} // Retrieves the session atttribute 'foo'        
${session.size()}       
${session.isEmpty()}        
${session.containsKey('foo')}    

3. application：获取应用程序/ servlet上下文属性

${application.foo} // Retrieves the ServletContext atttribute 'foo'        
${application.size()}        
${application.isEmpty()}        
${application.containsKey('foo')}

五：直接访问spring注册对象

<div th:text="${@authService.getUserName()}">

---

thymeleaf 页面获取当前页面的完整URL地址

下面两种方法是一样的

<div th:text="${#httpServletRequest.getRequestURL() + '?' + #httpServletRequest.getQueryString()}"></div>

<div th:text="${#httpServletRequest.requestURL + '?' + #httpServletRequest.queryString}"></div>
