jsp中自定义Taglib案例

一、使用TagSupport类案例解析

1.自定义Tag使用jdbc连接mysql数据库

1.1定义标签处理器类

package com.able.tag;

import java.sql.Connection;

import java.sql.DriverManager;

import java.sql.ResultSet;

import java.sql.SQLException;

import java.sql.Statement;

import javax.servlet.jsp.JspException;

import javax.servlet.jsp.tagext.TagSupport;

public class DBconnectionTag extends TagSupport {

	private String driver;// 连接驱动

	private String url;// 连接db地址

	private String password;// 连接db密码

	private String sql;// 查询sql

	private String username;// 连接db用户名

	Connection conn = null;

	Statement stmt = null;

	ResultSet rs = null;

	@Override

	public int doEndTag() throws JspException {

		try {

			Class.forName(this.driver);

			conn = DriverManager.getConnection(this.url,this.username,this.password);

			stmt = conn.createStatement();

			rs = stmt.executeQuery(this.sql);

			if (rs != null) {

				while (rs.next()) {

					pageContext.getOut().print(rs.getString("cname")+"<br/>");

				}

			}

			return EVAL_PAGE;

		} catch (Exception e) {

			e.printStackTrace();

			return SKIP_PAGE;

		} finally {

				try {

					if (rs != null) {

						rs.close();

					}

					if (stmt != null) {

						stmt.close();

					}

					if (conn != null) {

						conn.close();

					}

				} catch (SQLException e) {

					e.printStackTrace();

				}

		}

	}

	public String getDriver() {

		return driver;

	}

	public void setDriver(String driver) {

		this.driver = driver;

	}

	public String getUrl() {

		return url;

	}

	public void setUrl(String url) {

		this.url = url;

	}

	public String getPassword() {

		return password;

	}

	public void setPassword(String password) {

		this.password = password;

	}

	public String getSql() {

		return sql;

	}

	public void setSql(String sql) {

		this.sql = sql;

	}

	public String getUsername() {

		return username;

	}

	public void setUsername(String username) {

		this.username = username;

	}

}

1.2 在tag.tld文件中添加tag标签

 <tag>

	 	<name>DBconnectionTag</name><!-- 定义标签名 -->

	 	<tag-class>com.able.tag.DBconnectionTag</tag-class>

	 	<body-content>empty</body-content> <!-- 定义标签体为空 -->

	 	<attribute>

	 		<name>driver</name>

	 		<required>true</required>

	 		<rtexprvalue>true</rtexprvalue><!-- 可以使用el表达式接收参数 -->

	 	</attribute>

	 	<attribute>

	 		<name>url</name>

	 		<required>true</required>

	 		<rtexprvalue>true</rtexprvalue>

	 	</attribute>

	 	<attribute>

	 		<name>username</name>

	 		<required>true</required>

	 		<rtexprvalue>true</rtexprvalue>

	 	</attribute>

	 	<attribute>

	 		<name>password</name>

	 		<required>true</required>

	 		<rtexprvalue>true</rtexprvalue>

	 	</attribute>

	 	<attribute>

	 		<name>sql</name>

	 		<required>true</required>

	 		<rtexprvalue>true</rtexprvalue>

	 	</attribute>

	 </tag>

1.3 定义jsp,页面引入标签库，并定义标签

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>

<%

String path = request.getContextPath();

String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";

%>

<%-- <%@taglib uri="http://www.able.com" prefix="tm" %> --%>

<%-- <%@ taglib prefix="tm" uri="/WEB-INF/tlds/online.tld" %> --%>

<%@taglib prefix="tm" uri="/WEB-INF/tag.tld" %>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

<html>

  <head>

    <base href="<%=basePath%>">

    <title>My JSP 'index.jsp' starting page</title>

	<meta http-equiv="pragma" content="no-cache">

	<meta http-equiv="cache-control" content="no-cache">

	<meta http-equiv="expires" content="0">

	<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">

	<meta http-equiv="description" content="This is my page">

	<!--

	<link rel="stylesheet" type="text/css" href="styles.css">

	-->

  </head>

  <body>

  <tm:DBconnectionTag url="jdbc:mysql://192.168.9.223:3306/test_2016" driver="com.mysql.jdbc.Driver" username="root" password="ablejava" sql="select * from course"/>

	   <br/>

    <br>

  </body>

</html>

2.forEach循环遍历输出集合

2.1 定义自定义标签处理器类

package com.able.tag;

import java.util.Collection;

import java.util.Iterator;

import java.util.Map;

import javax.servlet.jsp.JspException;

import javax.servlet.jsp.tagext.TagSupport;

public class ForEachTag extends TagSupport {

	private String var;

	private Iterator<?> iterator;

	public void setItem(Object item) {

		if (item instanceof Map) {

			Map items = (Map) item;

			this.iterator = items.entrySet().iterator();

		} else {

			Collection<?> c = (Collection) item;

			this.iterator = c.iterator();

		}

	}

	@Override

	public int doStartTag() throws JspException {

		if (this.process())

			return EVAL_BODY_INCLUDE;

		else

			return EVAL_PAGE;

	}

	@Override

	public int doAfterBody() throws JspException {

		if (this.process()) {

			return EVAL_BODY_AGAIN;

		} else {

			return EVAL_PAGE;

		}

	}

	private boolean process() {

		if (null != iterator && iterator.hasNext()) {

			Object item = iterator.next();

			pageContext.setAttribute(var, item);

			return true;

		} else {

			return false;

		}

	}

	public String getVar() {

		return var;

	}

	public void setVar(String var) {

		this.var = var;

	}

}

2.3 在tld文件中定义标签

<tag>

		<name>foreach</name>

		<tag-class>com.able.tag.ForEachTag</tag-class>

		<body-content>JSP</body-content>

		<attribute>

			<name>var</name>

			<required>true</required>

			<rtexprvalue>true</rtexprvalue>

		</attribute>

		<attribute>

			<name>item</name>

			<required>true</required>

			<rtexprvalue>true</rtexprvalue>

			<!-- <type>java.lang.Object</type> -->

			 <type>java.util.Collection</type>

		</attribute>

	</tag>

2.4 在jsp页面定义循环标签

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>

<%

String path = request.getContextPath();

String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";

%>

<%-- <%@taglib uri="http://www.able.com" prefix="tm" %> --%>

<%-- <%@ taglib prefix="tm" uri="/WEB-INF/tlds/online.tld" %> --%>

<%@taglib prefix="tm" uri="/WEB-INF/tag.tld" %>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

<html>

  <head>

    <base href="<%=basePath%>">

    <title>My JSP 'index.jsp' starting page</title>

	<meta http-equiv="pragma" content="no-cache">

	<meta http-equiv="cache-control" content="no-cache">

	<meta http-equiv="expires" content="0">

	<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">

	<meta http-equiv="description" content="This is my page">

	<!--

	<link rel="stylesheet" type="text/css" href="styles.css">

	-->

  </head>

  <body>

  	<%

	    List<String> list = new ArrayList<String>();

	    list.add("aa");

	    list.add("bb");

	    list.add("cc");

	    Map map = new HashMap();

	    map.put("1","a");

	    map.put("2","b");

	    map.put("3","c");

	    map.put("4","b");

		%>

  	<tm:foreach var="hi" item="<%=map %>">

  		<h1>${hi }</h1>

  	</tm:foreach>

	   <br/>

    <br>

  </body>

</html>

3.定义Iterator循环输出数组

3.1定义标签处理器类

package com.able.tag;

import javax.servlet.jsp.JspException;

import javax.servlet.jsp.tagext.TagSupport;

public class IteratorTagDemo extends TagSupport {

	private String var;

	private String[] items;

	private int i =1;

	@Override

	public int doStartTag() throws JspException {

		if (items != null && items.length>0) {

			pageContext.setAttribute("name", items[0]);

			return EVAL_BODY_INCLUDE;

		} else {

			return SKIP_BODY;

		}

	}

	@Override

	public int doAfterBody() throws JspException {

		if (i<items.length) {

			pageContext.setAttribute("name", items[i]);

			i++;

			return EVAL_BODY_AGAIN;

		} else {

			return SKIP_BODY;

		}

	}

	@Override

	public int doEndTag() throws JspException {

		// TODO Auto-generated method stub

		return super.doEndTag();

	}

	public String getVar() {

		return var;

	}

	public void setVar(String var) {

		this.var = var;

	}

	public String[] getItems() {

		return items;

	}

	public void setItems(String[] items) {

		}

		if (items instanceof Object[]) {

			Object obj[]=(Object[]) items;

			collection=Arrays.asList(obj);

		}

		if (items.getClass().isArray()) {

			this.collection=new ArrayList();

			int length=Array.getLength(items);

			for (int i=0; i<length ; i++) {

				Object value=Array.get(items, i);

				this.collection.add(value);

			}

		}

	}

	public void setVar(String var) {

		this.var = var;

	}

	@Override

	public void doTag() throws JspException, IOException {

		Iterator it=this.collection.iterator();

		while (it.hasNext()) {

			Object value=it.next();

			this.getJspContext().setAttribute(var, value);

			this.getJspBody().invoke(null);

		}

	}

}

1.2定义.tld文件中添加标签

			}else{

				httpServletResponse.sendRedirect(httpServletRequest.getContextPath()+"/"+page);

			}

			throw new SkipPageException();

		}

	}

}

2.2 定义.tld文件

三、使用BodyTagSupport实现自定义Tag

1.继承BodyTagSupport实现简单数据输出

1.1定义标签处理器类

package com.able.bodyTag;

import java.io.IOException;

import javax.servlet.jsp.JspException;

import javax.servlet.jsp.JspWriter;

import javax.servlet.jsp.tagext.BodyContent;
