- 在web.xml中增加filter—openSessionInView,用于延长session在jsp调用完后再关闭

4、建立实体类,并加入Hibernate的注解
1)在实体类上加相应注解@Entity @Id等
2)在字段属性的get方法上加--@Column(name = "表字段名")
User.java
5、定义工具类
1)定义查询返回结果
QueryResult.java
- package ssh.utils;
- import java.util.List;
- /*
- * 定义查询返回的结果,泛型定义在类上
- */
- public class QueryResult<T> {
- private List<T> resultlist; //记录查询的结果
- private long totalrecord; //记录查询得到的总条数
- public List<T> getResultlist() {
- return resultlist;
- }
- public void setResultlist(List<T> resultlist) {
- this.resultlist = resultlist;
- }
- public long getTotalrecord() {
- return totalrecord;
- }
- public void setTotalrecord(long totalrecord) {
- this.totalrecord = totalrecord;
- }
- }
2)定义分页工具类
PageView.java
- package ssh.utils;
- import java.util.List;
- /**
- * 在Action里的调用方法
- //这里必须要构造新对象,不然刚打开没有currentPage参数传递过来,如果不新建也行,第一次打开必须传递currentPage参数过来
- private PageView<T>pageView=new PageView<T>();
- public PageView<T> getPageView() {
- return pageView;
- }
- public void setPageView(PageView<T> pageView) {
- this.pageView = pageView;
- }
- int maxresult=1;
- int firstindex=(pageView.getCurrentPage()-1)*maxresult;
- QueryResult<T> Service.getScrollData(firstindex,maxresult, null, null, null);
- pageView.setQueryResult(maxresult,qr);
- request.put("pageView", pageView);
- */
- public class PageView<T> {
- /** 分页数据 **/
- private List<T> records;
- /** 页码开始索引 ,例如显示第1 2 3 4 5 6 7 8 9 ,开始索引为1 **/
- private long startIndex;
- /** 页码结束索引 ,例如显示第1 2 3 4 5 6 7 8 9 ,结束索引为9 **/
- private long endIndex;
- /** 总页数 ,没有0页,所以设置默认值为1 **/
- private long totalPage = 1;
- /** 每页显示记录数 **/
- private int maxResult = 10;
- /** 当前页 **/
- private int currentPage = 1;
- /** 总记录数 **/
- private long totalRecord;
- /** 工具条上显示的页码数量 **/
- private int pageBarSize = 8;
- // 这只方法触发记录查询结果和总条数
- public void setQueryResult(int maxResult,QueryResult<T> qr) {
- this.maxResult = maxResult;
- this.records = qr.getResultlist();
- this.totalRecord = qr.getTotalrecord();
- this.totalPage = this.totalRecord % this.maxResult == 0 ? this.totalRecord/ this.maxResult : this.totalRecord / this.maxResult + 1;
- /*****************************************************/
- this.startIndex = currentPage - (pageBarSize % 2 == 0 ? pageBarSize / 2 - 1 : pageBarSize / 2);
- this.endIndex = currentPage + pageBarSize / 2;
- if (startIndex < 1) {
- startIndex = 1;
- if (totalPage >= pageBarSize)
- endIndex = pageBarSize;
- else
- endIndex = totalPage;
- }
- if (endIndex > totalPage) {
- endIndex = totalPage;
- if ((endIndex - pageBarSize) > 0)
- startIndex = endIndex - pageBarSize +1; //最后一页显示多小条页
- else
- startIndex = 1;
- }
- }
- public List<T> getRecords() {
- return records;
- }
- public void setRecords(List<T> records) {
- this.records = records;
- }
- public long getStartIndex() {
- return startIndex;
- }
- public void setStartIndex(long startIndex) {
- this.startIndex = startIndex;
- }
- public long getEndIndex() {
- return endIndex;
- }
- public void setEndIndex(long endIndex) {

- }
- public long getTotalPage() {

- }
- public void setTotalPage(long totalPage) {
- this.totalPage = totalPage;
- }
- public int getMaxResult() {
- return maxResult;
- }
- public void setMaxResult(int maxResult) {
- this.maxResult = maxResult;
- }
- public int getCurrentPage() {
- return currentPage;
- }
- public void setCurrentPage(int currentPage) {

- }
- public long getTotalRecord() {

- }
- public void setTotalRecord(long totalRecord) {
- this.totalRecord = totalRecord;
- }
- public int getPageBarSize() {

- public void setPageBarSize(int pageBarSize) {

- }
- }
