package com.bag.project.root; import javax.servlet.jsp.JspException; import javax.servlet.jsp.tagext.TagSupport; public class PrivilegeTag extends TagSupport { private static final long serialVersionUID = -532517444654109642L; private String operateID; //对应Attribute,加上set方法。 public void setOperateID(String operateID) { this.operateID = operateID; } public int doStartTag() throws JspException { if (operateID.equals("111111")) { // pageContext.getOut().write("html code"); 这里你可以输出html 代码 return EVAL_PAGE; } return SKIP_BODY; //跳过body,body部分不会显示 } }
