JSP带有标签体的自定义标签

1. 新建OutTag类


2. 如何添加jsp-api.jar包


3. OutTag类详细代码 ``` package bid.zhazhapan.fims.tag;

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

   public class OutTag extends BodyTagSupport {
   private boolean out;// 判断是否输出标签体的属性

   // 通过set方法获得页面out的属性值
   public void setOut(boolean out) {
   	this.out = out;
   }
   
   // 覆盖doStartTag()方法
   public int doStartTag() throws JspException {
   	if (out == true) {
   		return this.EVAL_BODY_INCLUDE;
   	} else {
   		return this.SKIP_BODY;
   	}
   }
   

   }
