================================java后台代码======================================
===========================业务层servicesImpl==================
// 用户管理查询用户信息
@SuppressWarnings("unchecked")

StringBuffer jql = new StringBuffer();

Map<String, Object> result = new HashMap<String, Object>();
result.put("total", total);

return parse2JSON(result);
}
=============dao,我这里用的是JPA，如果是ssh用户基本一样=======================
@Override
public List<T> qryPage(Class<T> clazz, int firstindex, int maxresult,
String whQl, Object[] params, LinkedHashMap<String, String> orderby) {
Query q = em.createQuery("SELECT u FROM " + clazz.getSimpleName()
+ " u " + (whQl ? "" : " where " + whQl)
+orderby);
setQueryParams(q, params);
if (firstindex >= 0) {
// q.setFirstResult(firstindex);
q.setFirstResult((firstindex - 1) * maxresult);
}
if (maxresult > 0) {
q.setMaxResults(maxresult);
}
return q.getResultList();
}
public void setQueryParams(Query query, Object[] params) {
try {
if (params != null && params.length > 0) {
for (int i = 0; i < params.length; i++) {
query.setParameter(i + 1, params[i]);
}
}
} catch (Exception e) {
e.printStackTrace();
}
}
==============================控制层action，我用的是springMVC=======================================
@Controller
@RequestMapping("index")
public class PubuserAction {
@Autowired
public PubuserServices pub;
// 刷新信息
@RequestMapping("qryUser")
public void qryUser(Pubuser pubuser, HttpServletRequest request,
HttpServletResponse response) throws IOException {
Pubuser us = (Pubuser) request.getSession().getAttribute(
JToolType.AttributeUserName);
pubuser.setGuid_gs(us.getGuid_gs());
String rslt = pub.qrypage(pubuser, request.getParameter("page"),
request.getParameter("rows"), request.getParameter("order"),
request.getParameter("sort"));
response.getWriter().write(rslt);
response.getWriter().close();
}
