demo中的代码如下，我没弄明白getSelection().getKeys()是获取到的key到底是什么？
还有怎么可以用这个key去和item.getName()即name属性比较呢？
public class ExtendedTableBean {
public void takeSelection(){
selectedCapitals.clear();
Iterator&Object& iterator = getSelection().getKeys();
while (iterator.hasNext()) {
Object key = iterator.next();
selectedCapitals.add(getCapitalsDataModel().getObjectByKey(key));
public ExtendedTableDataModel&Capital& getCapitalsDataModel() {
if (dataModel == null) {
dataModel = new ExtendedTableDataModel&Capital&(new DataProvider&Capital&(){
private static final long serialVersionUID = 3164847L;
public Capital getItemByKey(Object key) {
for(Capital c : capitals){
if (key.equals(getKey(c))){
public List&Capital& getItemsByRange(int firstRow, int endRow) {
return capitals.subList(firstRow, endRow);
public Object getKey(Capital item) {
return item.getName();
public int getRowCount() {
return capitals.size();
return dataM

package demo.page下的class：
* A simple class that represents a "page" of data out of a longer set, ie a
* list of objects together with info to indicate the starting row and the full
* size of the dataset. EJBs can return instances of this type when returning
* subsets of available data.
package demo.
import java.util.L
public class DataPage {
* 将需要的页的数据封装到一个DataPage中去， 这个类表示了我们需要的一页的数据，&br&
* 里面包含有三个元素：datasetSize，startRow，和一个用于表示具体数据的List。&br&
* datasetSize表示了这个记录集的总条数，查询数据的时候，使用同样的条件取count即可，&br&
* startRow表示该页的起始行在数据库中所有记录集中的位置
private int datasetS
private int startR
* @param datasetSize
数据集大小
* @param startRow
* @param data
public DataPage(int datasetSize, int startRow, List data) {
this.datasetSize = datasetS

public class User extends PageListBaseBean
public PagedListDataModel getDefaultDataModel()
if ( defaultDataModel == null ) {
defaultDataModel = new PagedListDataModel(pageSize)
public DataPage fetchPage(int startRow, int pageSize)
// call enclosing managed bean method to fetch the data

* TODO 带分页功能的基类
* @author &a href="mailto:"&TianLu&/a&

public abstract class PageListBaseBean {
* 当前页码，跟dataSroller的page属性绑定
protected int scrollerPage = 1;

protected PagedListDataModel defaultDataM
public int getScrollerPage() {
return scrollerP
public void setScrollerPage(int scrollerPage) {
this.scrollerPage = scrollerP
public int getPageSize() {
return pageS
public void setPageSize(int pageSize) {
this.pageSize = pageS
public abstract PagedListDataModel getDefaultDataModel();
* A special type of JSF DataModel to allow a datatable and datascroller to page
* through a large set of data without having to hold the entire set of data in
* memory at once.
* Any time a managed bean wants to avoid holding an entire dataset, the managed
* bean should declare an inner class which extends this class and implements
* the fetchData method. This method is called as needed when the table requires
* data that isn't available in the current data page held by this object.
* This does require the managed bean (and in general the business method that
* the managed bean uses) to provide the data wrapped in a DataPage object that
* provides info on the full size of the dataset.
