JSP自定义标签_控制标签余下的jsp不执行

什么也不说,直接上代码:

import java.io.IOException;

import javax.servlet.jsp.JspException;
import javax.servlet.jsp.SkipPageException;
import javax.servlet.jsp.tagext.SimpleTagSupport;

//控制标签余下的jsp不执行
public class SimpleTagDemo4 extends SimpleTagSupport {

    @Override
    public void doTag() throws JspException, IOException {
        throw new SkipPageException();
    }

    
    
}
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%@taglib uri="/simpleitcast" prefix="itcast"%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<itcast:demo4/>
<html>
  <head>
    <title>控制标签余下的 jsp不执行</title>
  </head>
  
  <body>
  </body>
</html>
<tag>
        <name>demo4</name>  <!-- 为标签处理器类配一个标签名 -->
        <tag-class>cn.itcast.web.simpletag.SimpleTagDemo4</tag-class>
        <body-content>scriptless</body-content>
    </tag>
