实现的功能：用YUI的datatable实现从服务器端获取数据，在前台页面展示，并实现分页的功能
使用的开发工具：jdk6+myeclipse6.6+tomcat6+yui2.8+struts2+spring+json
所需要的jar包： 13个
commons-beanutils-1.7.0.jar
?commons-collections-3.1.jar
?commons-httpclient-3.0.jar
?commons-lang-2.0.jar
?commons-logging-1.1.jar
?ezmorph-1.0.5.jar
?freemarker-2.3.8.jar
?json-lib-2.2.2-jdk15.jar
?ognl-2.6.11.jar

具体步骤如下：
1、新建工程yuiapp,导入所需要的jar和配置好tomcat，并能正常启动。
2、在yuiapp/WebRoot新建appjs/yuijs/build，具体的路径是/yuiapp/WebRoot/appjs/yuijs/build，然后把yui的build下的所有文件放进来。
3、配置web的内容，如下：
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.5" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee?? http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
? <context-param>
??? <param-name>contextConfigLocation</param-name>
??? <param-value>/WEB-INF/applicationContext.xml</param-value>
? </context-param>
? <listener>
??? <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
? </listener>
? <filter>
?? <filter-name>struts</filter-name>
?? <filter-class>org.apache.struts2.dispatcher.FilterDispatcher
?? </filter-class>
? </filter>
?
? <filter-mapping>
??<filter-name>struts</filter-name>
??<url-pattern>/*</url-pattern>
? </filter-mapping>
?
? <welcome-file-list>
??? <welcome-file>index.jsp</welcome-file>
? </welcome-file-list>
</web-app>
4、配置src下新建struts.xml，具体的路径是/yuiapp/src/struts.xml，具体的内容是
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
??????? "http://struts.apache.org/dtds/struts-2.0.dtd">
<struts>
?<include file="struts-default.xml"/>
?<constant name="struts.objectFactory" value="spring" />
?<package name="yuitab" namespace="/yuitab" extends="struts-default">
??<action name="do_*" method="{1}" class="com.demo.action.YuiTabAction">
??</action>
?</package>
</struts>
5、配置applicationContext.xml，具体的路径是/yuiapp/WebRoot/WEB-INF/applicationContext.xml，具体的内容是
<?xml version="1.0" encoding="UTF-8"?>
<beans
?xmlns="http://www.springframework.org/schema/beans"
?xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
?xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd">
</beans>
?
其实就是一个空文件

6、编写Action和Bean类
6.1 YuiTabAction.java
package com.demo.action;
import java.io.IOException;
import java.io.PrintWriter;
import java.util.ArrayList;
import java.util.List;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import net.sf.json.JSONArray;
import net.sf.json.JSONObject;
import org.apache.struts2.ServletActionContext;
import com.opensymphony.xwork2.ActionSupport;
@SuppressWarnings("all")
public class YuiTabAction extends ActionSupport{
?@Override
?public String execute() {
??System.out.println("............ execute() is called....");
??return SUCCESS;??
?}
?
?public void getBookList(){
??System.out.println(" getBookList is called....startIndex="+startIndex);
??List<Book> bookList = new ArrayList<Book>();
??recordsReturned = 10;
??for(int i=1; i<10; i++){
???Book book = new Book();
???book.setId(startIndex+i);
???book.setAmount(startIndex+i+10);
???book.setQuantity(startIndex+i+100);
???book.setTitle("title("+startIndex+i+")");
???bookList.add(book);
??}
??pageSize = 10;
??totalRecords = 20;//假设总记录数是20条,
??YUIPagination yuiPage = new YUIPagination();
??yuiPage.setRecordsReturned(recordsReturned);
??yuiPage.setTotalRecords(totalRecords);
??yuiPage.setStartIndex(startIndex);
??yuiPage.setPageSize(pageSize);
??yuiPage.setSort("ASC");
??yuiPage.setRecords(bookList);??
??this.outJson(yuiPage);?
?}
?
?public HttpServletRequest getRequest() {
??return ServletActionContext.getRequest();
?}
?public HttpServletResponse getResponse() {
??return ServletActionContext.getResponse();
?}
?public void outJsonString(String str) {
??getResponse().setContentType("text/javascript;charset=UTF-8");
??outString(str);
?}
?public void outJson(Object obj) {
??outJsonString(JSONObject.fromObject(obj).toString());
?}
?public void outJsonArray(Object array) {
??outJsonString(JSONArray.fromObject(array).toString());??
?}
?public void outString(String str) {
??try {
???PrintWriter out = getResponse().getWriter();
???out.write(str);
??} catch (IOException e) {
??}
?}
?public void outXMLString(String xmlStr) {
??getResponse().setContentType("application/xml;charset=UTF-8");
??outString(xmlStr);
?}
?
?protected int recordsReturned;
?protected int totalRecords;
?protected int startIndex;
?protected String sort;??
?protected String dir;
?protected List records;
?protected int pageSize;
?//getter and setter
}
6.2 YUIPagination.java
package com.demo.action;
import java.util.List;
@SuppressWarnings("all")
public class YUIPagination {
?private int recordsReturned;
?private int totalRecords;
?private int startIndex;
?private String sort;??
?private String dir;
?private List records;
?private int pageSize;
//getter and setter
}
?
6.3 Book.java
package com.demo.action;
public class Book {
?private Integer id;
?private Integer quantity;
?private Integer amount;
?private String title;
//getter and setter
}
?
