iftag.java

非常经典的ssh整合实例

package com.briup.tag;

import java.io.IOException;

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

public class IfTag extends SimpleTagSupport {
	private boolean test;
	public void setTest(boolean test){
		this.test=test;
	}
	@Override
	public void doTag() throws JspException, IOException {
		//如果传入进行的test为true，并且标签体有内容，那么执行标签体
	    //JspFragment
		if(test&&super.getJspBody()!=null){
			//那么执行标签体
			super.getJspBody().invoke(null);
		}
		
	}
}
