如果我想从bean中获取属性并将其用于某些Java代码。例如,获取访问者计数,但不输出,仅用于其他用途。我不能使用,因为它将输出值。
如何获取属性而不输出?

您可以将属性设置为任何变量,然后可以对其进行处理。
<c:set var="name" scope="scope" value="expression"/>
例如:
<c:set var="visitorCount" scope="scope" value="someBean.counter"/>
甚至你也可以在不设置的情况下处理它
此示例检索会话范围的bean,并使用id myBean使其可用。虽然在jsp代码中使用scriptlet不是一个好的做法,但一种方法是调用bean上的任何方法,如下所示。
<jsp:useBean id="myBean" class="com.mycompany.MyBean" scope="session" />
<% myBean.getprop1(); %>
<jsp:useBean id ="object instance" class="full qualified path of ur class" scope="according to need"/>
<jsp:getProperty name="same as id" property="name of the property"/>
根据这个使用u必须在不使用脚本的情况下获得ur结果。。。。
