ibatIS的parameterClass="java.util.HashMap"使用Map类型参数

 

ibatIS中的parameterClass，一般分类两种，1种为传model，另一种为传map

 

一、parameterClass传model参数

<select id="queryModel"  parameterClass="com.hanpeng.base.phone.model.TDictionary" resultClass="com.hanpeng.base.phone.model.TDictionary">
SELECT
		 D_CODE  as dCode ,			
		 D_NAME  as dName ,			
		 D_INFO  as dInfo ,			
		 D_SERVER_NAME  as dServerName ,			
		 D_CLIENT_NAME  as dClientName ,			
		 REMARK  as remark ,			
		 D_SHORT  as dShort ,			
		 D_SERVER_COLOR  as dServerColor ,			
		 D_CLIENT_COLOR  as dClientColor 			
FROM  T_DICTIONARY 
<dynamic prepend="WHERE">
		<isNotEmpty prepend=" AND " property="dCode">
		D_CODE =  #dCode# 		</isNotEmpty>
		<isNotEmpty prepend=" AND " property="dName">
		D_NAME =  #dName# 		</isNotEmpty>
		<isNotEmpty prepend=" AND " property="dInfo">
		D_INFO =  #dInfo# 		</isNotEmpty>
		<isNotEmpty prepend=" AND " property="dServerName">
		D_SERVER_NAME =  #dServerName# 		</isNotEmpty>
		<isNotEmpty prepend=" AND " property="dClientName">
		D_CLIENT_NAME =  #dClientName# 		</isNotEmpty>
		<isNotEmpty prepend=" AND " property="remark">
		REMARK =  #remark# 		</isNotEmpty>
		<isNotEmpty prepend=" AND " property="dShort">
		D_SHORT =  #dShort# 		</isNotEmpty>
		<isNotEmpty prepend=" AND " property="dServerColor">
		D_SERVER_COLOR =  #dServerColor# 		</isNotEmpty>
		<isNotEmpty prepend=" AND " property="dClientColor">
		D_CLIENT_COLOR =  #dClientColor# 		</isNotEmpty>
	</dynamic>
</select>

 

二、parameterClass传map参数

1.

/**
 * 快速备注
 * @param request
 * @return
 * @author sgdjava
 * @date 2011-9-8 下午05:00:14
 */
public static List getKuaiSuBeiZhu(HttpServletRequest request) {
	List result = null;
	try {
		
		String sendtype="";
		if(request.getAttribute("sendType") != null)
			sendtype = (String)request.getAttribute("sendType");
		Map search = new HashMap();
		search.put("wbType", sendtype);
		
		result = selectUtilSerivce.queryKuaiSuBeiZhu(search);
	} catch (Exception e) {
		log.error("SelectUtilReq getKuaiSuBeiZhu Err",e);
	}
	return result;
}

 2.daoImpl

public List<Map<String, Object>> queryKuaiSuBeiZhu(Map searchMap) {
	return getSqlMapClientTemplate().queryForList("TDictionary.queryKuaiSuBeiZhu", searchMap);
}

 3.sqlMap

<select id="queryKuaiSuBeiZhu"  parameterClass="java.util.HashMap" resultClass="java.util.HashMap">
SELECT T.WB_INFO AS "val" , T.WB_INFO AS "key"  FROM T_WRITE_BACK T 
	<dynamic prepend="WHERE">
		<isNotEmpty prepend=" AND " property="wbType">
			T.WB_TYPE=#wbType# 		</isNotEmpty>
	</dynamic>
ORDER BY T.WB_NUM ASC
</select>
