问题出处Q公怸个项目中使用动态sql方式查询Oracle数据库，在展C时Datecd字段只展C日期，无时分秒?/span>
分析Q?/span>
1、众所周知Oralce的日期类型有很多U，Date ,Timestamp{。其中Datecd对用的是java.sql.DatecdQTimestamp对用的是java.sql.Timestampcd。这两个cd均承自java.util.Date,其中java.sql.Date是没有时分秒的大家可以查看一下javaApi
2、ResultSet 的getObjectQ?Q方法对用Datecd默认q回的是java.sql.Date
3、网上很多h提供的解x案是数据库Datecd改ؓ(f)TimestampcdQ显C当中数据库cdDBA是不?x)允怽改动的，且Oracle中对于时分秒要求不严格的地方DBA反而是用Date而不用Timestamp以节省资?/span>
4、ibatis的ResultMap中对Datecd指定为Timestamp却能够正常显C?/span>

JAVA中编写类CacheManagerQ方法如下：(x)
public void contextInitialized(javax.servlet.ServletContextEvent arg0) {
WebInfoDBO webInfoDBO = (WebInfoDBO) SpringContext.getBean("WebInfoDBO");
List list = webInfoDBO.queryBySql(" select detail_id as \"detailId\", genre_id as \"genreId\",type_two as \"typeTwo\", " + "title_name as \"titleName\",is_issue as \"isIssue\",is_hot as \"isHot\",content as \"content\"" + "from (select detail_id,genre_id,type_two, title_name, is_issue,is_hot,(select content from web_content c where web_info_d.detail_id=c.detail_id and is_hot='1') content,"
+ "rank() over(partition by genre_id order by sort_code,upt_date desc) rn from web_info_d where is_issue='1') where rn<=1", WebInfoD.class);
for (int i = 0; i < list.size(); i++) {
WebInfoD webInfoD = (WebInfoD) list.get(i);
tableComent.put("webInfoD", webInfoD);
}
}
在JSP面获取值方法：(x)CacheManagerQ?br />CacheManager cm = new CacheManager();

out.println(webInfoD.getDetailId());
out.println(cm.tableComent.get("detailId"));
