1.编写标签对应的实现类
package com.jiang.test; import java.io.IOException; import java.io.StringWriter; import javax.servlet.jsp.JspException; import javax.servlet.jsp.tagext.SimpleTagSupport; public class TestTag extends SimpleTagSupport { /** * 标签中的属性 */ private String message; public void setMessage(String msg) { this.message = msg; } StringWriter sw = new StringWriter(); public void doTag() throws JspException, IOException { System.out.println(message); sw.write("<h1>"); getJspBody().invoke(sw); getJspContext().getOut().println(sw.toString()); } } 2.创建tld文件，文件放在web-inf下
<?xml version="1.0" encoding="UTF-8"?> <taglib> <tlib-version>1.0</tlib-version> <jsp-version>2.0</jsp-version> <short-name>Example TLD with Body</short-name> <tag> <name>test</name> <tag-class>com.jiang.test.TestTag</tag-class> <body-content>scriptless</body-content> <attribute> <name>message</name> </attribute> </tag> </taglib>
3.jsp文件中使用标签
<body> <ts:test message="jiang"> 1111111111111 </ts:test> </body>
