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}});

}
