JSP 自定义标�{?br /> 1. pass 的徏立是(1)tld文�g�?(2).java�?private String pass gget() gset()
2. 要有 Body .java ��q��?BodyTagSupport 不要��? TagSupport
3. doStartTag() �?输出是�?pageContext.getOut().print("hello."+this.pass);
4. doAfterBody() �?输出�?BodyContent bc = super.getBodyContent();
                            String bStr = bc.getString(); // body 中的 string
                              bc.getEnclosingWriter().print(...); // out to jsp
5.
             //会先�q�行得到 String 再在 bc.getString()得到 String
            XX


4. .java �?通过�?doStartTag()
                        return SKIP_BODY 跛_�� doEndTag()
                      return EVAL_BODY_INCLUDE 跌��M�� doBodyContent()
                      return EVAL_BODY_BUFFERED 调用doInitBody()
5. .java �?doAfterBody()

                      return EVAL_BODY_AGAIN 再次 doAfterBody()
6. .java �?doEndTag()
                      retrun EVAL_PAGE �l�箋剩余
                      return SKIP_PAGE 跛_��

Tag 自定义标�{?br /> 1. <%@ taglib prefix="my" tagdir="/WEB-INF/tags" %> 倒入 �q�在 tags 文�g�?�?XXX.tag
2. 使用 EG:
3. 在文�?tag中加�?<%@ attribute name="items"%>
                                 �q�在 body�?{items}��可以��?br /> 4. body加标�{?�?JSP 自定义标�{?5
5.
        //��d��body模块
            ..<>..


       �?.tag �?<%@ attribute name="list" fragment="true" required="true" %> 取得
