第十壹節:Thymeleaf內置對象

1.ctx: the context object ?

ctx對象繼承org.thymeleaf.context.IContext或者org.thymeleaf.context.IWebContext，取決於當前環境是不是web環境。

如果程序集成了spring，那麽將會是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

訪問VariablesMap所有上下文中的變量

#org.thymeleaf.context.VariablesMap

${#vars.get('foo')}

${#vars.containsKey('foo')}

${#vars.size()}

3.locale: the context locale

java.util.Locale對象的訪問

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環境對象

1.#httpServletRequest :javax.servlet.http.HttpServletRequest對象實例

${#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環境對象

#themes : 提供和“ spring:theme JSP tag.”同樣的功能。

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

四：web環境中訪問request/session等屬性

1.param :獲取請求的參數.

${param.foo} // Retrieves a String[] with the values of request parameter 'foo'

${param.size()}

${param.isEmpty()}

${param.containsKey('foo')}

2.session:訪問session屬性

${session.foo} // Retrieves the session atttribute 'foo'

${session.size()}

${session.isEmpty()}

${session.containsKey('foo')}

3.application：獲取應用程序/ servlet上下文屬性

${application.foo} // Retrieves the ServletContext atttribute 'foo'

${application.size()}

${application.isEmpty()}

${application.containsKey('foo')}

五：直接訪問spring註冊對象

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