Spring mvc hibernate 分页
以前做的项目都是SSH框架，当然分页参数的传递可以通过' .../../.jsp?startIndex='+startIndex 传递，但在SpringMVC +Hibernate框架下后台不能获取startIndex的参数，形式是'.../../.htm?startIndex='+startIndex ,研究半
天，终于搞定，至于为什么不清楚？
1：application.xml 配置信息(部分)
<bean id="test3Service" class="test.Test3ServiceImpl">
<property name="sessionFactory" ref="sessionFactory"> </property>
</bean>
2：application-security.xml 配置如下(部分)
<security:intercept-url pattern="/*.htm" access="IS_AUTHENTICATED_REMEMBERED"/>
3：spring-mvc-servlet.xml 配置如下(部分)
<bean name="/Test3.htm" class="test.Test3Controller">
<property name="test3Service" ref="test3Service"/>
</bean>
4：Test3Service 接口
public interface Test1Service {
public List<Expert> findExpertList();
}
5：Test3ServiceImpl 实现
public class Test3ServiceImpl extends HibernateDaoSupport implements
Test3Service {
@Override
public PaginationSupport findPageByQuery(int pageSize,
int startIndex) {
Session session = this.getHibernateTemplate().getSessionFactory().openSession();
String hsql = " from Expert e order by id desc";
Query query = session.createQuery(hsql);
int totalCount=query.list().size();
query.setFirstResult(startIndex);
query.setMaxResults(pageSize);
List items = query.list();
PaginationSupport ps = new PaginationSupport(items,
totalCount, pageSize, startIndex);
session.close();
return ps;
}
}
6：Test3Controller
public class Test3Controller implements Controller {
private static Logger log = Logger.getLogger("Test3Controller");
private Test3Service test3Service;
private PaginationSupport userPage;
private int pageSize = 10;
private int startIndex;
private List experts;
@Override
public ModelAndView handleRequest(HttpServletRequest request,
HttpServletResponse response) throws Exception {
log.info("Test3Controller 分页查询！");
String i = request.getParameter("startIndex");
if (i != null || "".equals(i)) {
startIndex = Integer.parseInt(i);
System.out.println("ii:" + i + "startIndex:" + startIndex);
}
userPage = test3Service.findPageByQuery(pageSize, startIndex);
request.setAttribute("userPage", userPage);
return new ModelAndView("Test3", "experts", userPage.getItems());
}
public Test3Service getTest3Service() {
return test3Service;
}
public void setTest3Service(Test3Service test3Service) {
this.test3Service = test3Service;
}
public PaginationSupport getUserPage() {
return userPage;
}
public void setUserPage(PaginationSupport userPage) {
this.userPage = userPage;
}
public int getPageSize() {
return pageSize;
}
public void setPageSize(int pageSize) {
this.pageSize = pageSize;
}
public int getStartIndex() {
return startIndex;
}
public void setStartIndex(int startIndex) {
this.startIndex = startIndex;
}
public List getExperts() {
return experts;
}
public void setExperts(List experts) {
this.experts = experts;
}
}
