Jsp分页原代码，及用法

１.定义一个分页的Tag Bean,以便用户在Jsp页中使用自定义标签，用户在使用时可以相应的描述



package BSC.tree;



import javax.servlet.jsp.*;

import javax.servlet.jsp.tagext.*;

import javax.servlet.jsp.tagext.TagSupport;

import javax.servlet.http.HttpServletResponse;

import org.apache.struts.action.ActionServlet;

import java.sql.*;

import BSC.pool.*;

import java.util.*;

//import java.util.regex.Pattern;

import pubBean.Patten;

import BSC.tree.pagetag.*;

/**

* @author 丁小龙(DingXiaolong)

* @version 1.1

* @deprecated 能够通过SQL语句产生一个GRID并且可通过相应的CSS设置相应的属性

* @param strSQL 需要执行的查询SQL语句

* @param pageSize Grid每一页所生的记录行数(Row)

* @param action 当点分页素引号码所要跳转的页面名称,必须是使用本标志页面的名称

* @param style 整个Grid的CSS的CLASS的设置

* @param ctrPageBeanSessionNM 内部使用

* @param pageTileBeanSessionNM 未使用,暂保留

* @param databeanNM 存储Grid所有数据集合,如果和ScriptTag对应的标志类合用时候,必须与其name使用相同值

* @param loginIndexSessionNM 存储物理数据与逻辑数据的索引对应的集合名称,如果和ScriptTag对应的标志类合用时候,必须与其loginIndexSessionNM使用相同值

* @param caption Grid表头标题,各列(Col)的标题用逗号(",")隔开,且数量必须和SQL语句所列出的字段一致

* @param isHidden Grid各列是否显示(0--显示,1--为不显示),各列(Col)是否显示值用逗号(",")隔开,且数量必须和SQL语句所列出的字段一致

* @param trStyle Grid各行的CSS设置值

* @param tableWidth Grid表的宽度,可以是绝对值的表达方式,也可以是相对值的表达方式

* @param tdWidth Grid各列(col)之宽度,各列(Col)宽度用逗号(",")隔开,且数量必须和SQL语句所列出的字段一致

* @param database 在Sturts-config中设置的datasource key名

2.定义次Tag Bean,它是一个用呈现特殊html组件，如text,button等

package BSC.tree;



import javax.servlet.jsp.*;

import javax.servlet.jsp.tagext.*;

import javax.servlet.jsp.tagext.TagSupport;

import javax.servlet.http.HttpServletResponse;

import java.sql.*;



import java.util.*;

import pubBean.*;

import BSC.tree.pagetag.*;



public class ScriptTag

extends BodyTagSupport {

private String name;

private String property;

private String value;

private String index;

private String loginIndexSessionNM;

private String caption;

private String isHidden;

protected static int scope = 2;

private String width;

public ScriptTag() {

}



public String getName() {

return name;

}



public void setName(String name) {

this.name = name;

}



public String getProperty() {

return property;

}



public void setProperty(String property) {

this.property = property;

}



public String getValue() {

return value;

}



public void setValue(String value) {

this.value = value;

}



public int doEndTag() throws javax.servlet.jsp.JspException {

/**@todo Override this javax.servlet.jsp.tagext.BodyTagSupport method*/

System.out.println("In Class ScriptTag ''s doEndTag()");

try {



System.out.println("The scope is "+this.scope);

PageDataBean databean = (PageDataBean)this.pageContext.getAttribute(this.

getName(), scope);

Vector logicIndexs = (Vector)this.pageContext.getAttribute(this.

getLoginIndexSessionNM(), scope);

if (databean == null) {

System.out.println("Create the DataBean...");

databean = new PageDataBean();



}

if (logicIndexs == null) {

logicIndexs = new Vector();

}



logicIndexs.addElement(this.getIndex());

databean.getColnameindex().addElement("Script,,," + this.getProperty());

databean.getDataArray().put("Script,,," + this.getProperty(),

databean.getCaptionArray().put("Script,,," + this.getProperty(),

this.getCaption());

databean.getIsHiddenArray().put("Script,,," + this.getProperty(),

this.getIsHidden());

databean.getWidthArray().put("Script,,,"+this.getProperty(),

this.getWidth());



pageContext.setAttribute(this.getName(), databean, scope);

pageContext.setAttribute(this.getLoginIndexSessionNM(), logicIndexs,

scope);



}

catch (Exception e) {

System.out.println("ScriptTag Error:" + e.getMessage());

}

return super.doEndTag();

}



public String getIndex() {

return index;

}



public void setIndex(String index) {

this.index = index;

}



public String getLoginIndexSessionNM() {

}



public void setLoginIndexSessionNM(String loginIndexSessionNM) {

}

}

}

this.isHidden = isHidden;

}

public String getWidth() {

return width;

}

public void setWidth(String width) {

this.width = width;

}



}

３．定义一个用于执行sql查询语句，并将相应的数保存到该Bean里面

package BSC.tree.pagetag;

import java.sql.*;

import java.util.*;

public class PageDataBean {



private Vector dataList=new Vector();

private String strSQL="";

private String colCount="0";

}

protected void setDataList(java.util.Vector dataList) {

}

public String getStrSQL() {

}

public void setStrSQL(String strSQL) {

this.strSQL = strSQL;

}

public void init(Connection conn){

try{

// Statement stat=conn.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE,ResultSet.CONCUR_READ_ONLY);

Statement stat=conn.createStatement();

ResultSet rs=stat.executeQuery(this.getStrSQL());

ResultSet tmrs=null;

if(rs!=null){

int colcount=rs.getMetaData().getColumnCount();

this.setColCount(""+colcount);

while(rs.next()){

reccount++;

Vector rowDate=new Vector();

for(int i=1;i<=colcount;i++){

}

this.getDataList().addElement(rowDate);

}

for(int i=1;i<=colcount;i++){

this.getColnameindex().addElement(rs.getMetaData().getColumnName(i));

}

if(reccount!=0){

for (int i = 1; i <= colcount; i++) {



//rs.first();

tmrs=stat.executeQuery(this.getStrSQL());

Vector cols = new Vector();

while (tmrs.next()) {

cols.addElement(notNull(tmrs.getString(i)));





}

this.addNode(tmrs.getMetaData().getColumnName(i), cols);

tmrs.close();

}

}





}



}catch(Exception e){

System.out.print("PageDataBean Error: "+e.getMessage());

}

}

public String getColCount() {

return colCount;

}

protected void setColCount(String colCount) {

this.colCount = colCount;

}

public java.util.Hashtable getDataArray() {

return dataArray;

}

public void setDataArray(java.util.Hashtable dataArray) {

}

void addNode(String name,Object obj) throws IllegalArgumentException {



synchronized (dataArray) {



if (dataArray.containsKey(name))

throw new IllegalArgumentException("Column name ''" + name +

}



public java.util.Vector getColnameindex() {

}

public void setColnameindex(java.util.Vector colnameindex) {

this.colnameindex = colnameindex;

}

public java.util.Hashtable getCaptionArray() {

}

public void setCaptionArray(java.util.Hashtable captionArray) {

}

}

public java.util.Hashtable getWidthArray() {

}

}



/**

*

* @param aStr String

*/

public String notNull(String aStr) {

if(aStr!=null)

return aStr.trim();

else

return "";

}



}

４．定义一个主控类，用于保存分页Grid的页面信息

package BSC.tree.pagetag;



public class CtrPageBean {



private String next="1";

private String last="1";

private String current="1";

private String size="0";

private String max="1";

private String pageSize="0";

public CtrPageBean(String size,String pageSize) {



if(this.getInteger(size)!=0){

if(this.getInteger(pageSize)<0)

this.setPageSize(size);

this.setSize(size);

this.setPageSize(pageSize);

if (this.getInteger(pageSize) > this.getInteger(size)) {

this.setPageSize(size);

}

if (pageSize == "0")

this.setPageSize("1");

int leval = this.getInteger(getSize()) % this.getInteger(this.getPageSize());

int maxv = 0;

if (leval == 0) {

maxv = this.getInteger(getSize()) / this.getInteger(this.getPageSize());

}

else {

maxv = this.getInteger(getSize()) / this.getInteger(this.getPageSize()) +

1;

}



this.setMax("" + maxv);

}



}

public String getMax() {

return max;

５．定义一个名叫page_table.tld的tld文件，并将其存放到\WEB-INF目录下内容

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE taglib PUBLIC "-//Sun Microsystems, Inc.//DTD JSP Tag Library 1.1//EN" "http://java.sun.com/j2ee/dtds/web-jsptaglibrary_1_1.dtd">

６．在jsp中使用，

<%@ page contentType="text/html; charset=Big5" %>

<%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean" %>

<%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html" %>

<%@ taglib uri="/WEB-INF/struts-logic.tld" prefix="logic" %>

<%@ taglib uri="/WEB-INF/page_table.tld" prefix="pagetab"%>

<%@ page import="BSC.pool.*" %>

<html>

<head>

<title>

login

</title>

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

<script language="JavaScript" src="js/PubFun.js" type="text/javascript"> </script>

</head>

<body bgcolor="#ffffff">

<logic:present name="userManageForm">

<bean:write name="userManageForm" property="email"/>

</logic:present>

<logic:notPresent name="userManageForm">

addddddddddd

</logic:notPresent>

<!--bean:write name="userManageForm" property="email"/-->



<%

//以下就是产生分页Grid的代码

String index="1";

index=request.getParameter("index");

if(index==null)

index="1";



%>



<pagetab:PageScriptTag

logicIndex="0,1"

pageSize="10"

isHidden="0,0"

action="TestGrid.jsp"

style="outtable"

currentSize="<%=index%>"

strSQL="select ttid,Type from Trans_Type"

databeanNM="databeanname"

loginIndexSessionNM="loginIndexSessionNM"

caption="县市ID,县市名称"

headTrStyle="text1"

tdWidth="5%,20%"

database="resources.SQLServerDB"

/>

</body>

</html>
