（1）map取值

（2）key取值

2、实现示例

 <html>
   <head>
     <meta http-equiv="content-type" content="text/html; charset=UTF-8">
     <title>freemarker处理哈希表的内建函数</title>

   </head>

   <body>
      <#--freemarker HashMap取值-->
      <#assign maps={"1":"张三丰","2":"李思思","3":"张三强","4":"王五"}>
      ${maps["3"]}

      <#assign stu={"name":"zhangsan","age":"21","sex":"man"}>
      <#assign keys = stu?keys>
      <#list keys as key>
          ${key} = ${stu[key]};
      </#list>
   </body>
 </html>

3、示例结果
