[置顶]       ibatis查询oracle分页

开发采用spring+struts+ibatis+extjs，数据库用oracle    ibtais配置分页 模糊查询     Java代码   <sqlMap namespace="RYDM" >   <!--加载 分页对象-->     <typeAlias alias="page" type="com.portal.util.Page" />   <!--加载 实体对象-->    <typeAlias alias="abatorgenerated_RydmResult" type="com.portal.model.Rydm" />     <resultMap id="abatorgenerated_RydmResult" class="com.portal.model.Rydm" >    <result column="RYDM" property="rydm" jdbcType="VARCHAR" />       <result column="RYMC" property="rymc" jdbcType="VARCHAR" />        <result column="BMZDM" property="bmzdm" jdbcType="VARCHAR" />         <sql id="findByPageCondition">           <isNotEmpty property="objCondition">                   <isNotEmpty property="objCondition.bmzdm">                        bmzdm LIKE '%$objCondition.bmzdm$%'                   </isNotEmpty>                   <isNotEmpty property="objCondition.rymc">                       AND rymc LIKE '%$objCondition.rymc$%'                       </isNotEmpty>           </isNotEmpty>       </sql>       <select id="findByPage" parameterClass="page"                                 resultClass="abatorgenerated_RydmResult">               SELECT * FROM (SELECT row_.*, rownum rownum_ FROM                       (select ry.* from RYDM ry                         where 1=1             <dynamic prepend="AND">               <include refid="findByPageCondition" />           </dynamic>                      )row_ WHERE rownum <= $limit$)row_ WHERE rownum_ >$start$                ORDER BY rydm       </select>       <select id="findByCount" parameterClass="page" resultClass="int">               SELECT COUNT(*) FROM RYDM ry   where 1=1           <dynamic prepend="AND">               <include refid="findByPageCondition" />           </dynamic>       </select>         分页模型通用类     Java代码   public class Page implements java.io.Serializable{          public void setPageProperty(Page page) {           if(page.getStart()>0){           // 设置取数据的区间           int endPage=page.getStart()+page.getLimit();            int stratPage=page.getStart();           this.setStart(stratPage);           this.setLimit(endPage);           }else{               this.setLimit(page.getLimit());               this.setStart(0);           }       }          /** 总记录数 */       private int totalProperty;          /** 分页结果 */       private List root;          /** 开始页码 */       private int start;          /** 每页多少 */       private int limit;          /** 成功与否 */       private boolean success;          /** 查询条件 */       private Object objCondition;     实体类  Java代码   public class Rydm implements Serializable{       /**       * This field was generated by Abator for iBATIS.       * This field corresponds to the database column RYDM.RYDM       *       * @abatorgenerated Sat Aug 06 16:55:26 CST 2011       */       private String rydm;             private String rymc;          private String bmzdm;         服务层调用  Java代码   public class RydmServiceImpl extends SqlMapClientDaoSupport implements           RydmService {          public Page findByPageRydm(Page page) throws BusinessException {           page.setTotalProperty((Integer) getSqlMapClientTemplate()                   .queryForObject("RYDM.findByCount", page));           page.setPageProperty(page);           page.setRoot(getSqlMapClientTemplate().queryForList(                   "RYDM.findByPage", page));           return page;       }         action设置分页属性  Java代码   public class UsersAction extends ActionSupport implements ServletRequestAware,   SessionAware{       public String message;       public String conditions;       protected Map session;//会话对象       protected HttpServletRequest request;//请求对象   /*       * 查询用户信息       */       public String listUser() {           Rydm user=new   Rydm();                           user.setBmzdm(request.getParameter("bmzdm").toString());           user.setRymc(request.getParameter("rymc").toString());           int start =0;           int Limit=10;           Page page = new Page();          try {           start = Integer.valueOf(getRequest().getParameter("start"));           Limit = Integer.valueOf(getRequest().getParameter("limit"));           }catch (NumberFormatException e) {           }           page.setStart(start);           page.setLimit(Limit);           //使用对象作为查询参数 传入ibtais           page.setObjCondition(user);           page = userService.findByPage(page);           } catch (BusinessException e) {               log.warn("UsersAction.class查询用户信息出现异常"+e.getMessage(), e);           }           return SUCCESS;       }   }     返回配置 我是使用了ext  所以转换json 显示到客户端  Java代码   <package name="admin" extends="json-default" namespace="/admin">              <action name="listUser" class="userAction" method="listUser">               <result type="json">                   <param name="root">page</param>                   <param name="excludeProperties">limit,start,objCondition</param>               </result>           </action>   </package>         extjs 参数查询  Js代码   var rydm_store = new Ext.data.Store({       proxy : new Ext.data.HttpProxy({           url : "/extDemo/admin/userList.action",           method:"post"       }),       reader : new Ext.data.JsonReader({           totalProperty : 'totalProperty',           root : 'root',           fields : [  {               name : 'bmzdm',               type : 'string'           } , {               name : 'bmmc',               type : 'string'           }]       })   });      var btn_search_rydm = new Ext.Button({       text : '查询',       iconCls : 'icon-search',       handler : queryRydm   });         var queryRydm = function() {       rydm_store.baseParams.bmzdm= bmzdm_search_rydn.getValue();       rydm_store.baseParams.rymc =text_search_rydm.getValue();       rydm_store.load({params : {start : 0,limit : 15}});          }
