常用标签

c:if

<c:if  test=""  var="" [scope="page|request|session|application"]/>

<c:if test=""> body</c:if>

 

c:set ||  c:out

<c:out value="" [default=""] [escapeXml="true|false"]>    //escapseXml 是否转换特殊字符 

<jsp:useBean id="user" class="Entity.User" scope="request"></jsp:useBean>
<jsp:setProperty property="name" name="user" value="张三"/>
<jsp:getProperty property="name" name="user"/>

上面代码等价于下面代码

<c:set target="${user }" property="name" value="lisi"/>
<c:out value="${user.name }"/>

 <meta>

<meta http-equiv|name|scheme =""  content="String" >        //meta标签HTML中的全局属性,相当于name,value
