方法一：类转换为map
JAVA中编写类CacheManager，方法如下：
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页面获取值方法：CacheManager：
CacheManager cm = new CacheManager();
WebInfoD webInfoD = (WebInfoD) cm.tableComent.get("webInfoD");
out.println(webInfoD.getDetailId());
out.println(cm.tableComent.get("detailId"));
方法二：类转换为map中KEY，VALUE
JAVA中：
public void contextInitialized(javax.servlet.ServletContextEvent arg0) {
SysDictBO sysDictBO = (SysDictBO) SpringContext.getBean("SysDictBO");
List list = sysDictBO.queryBySql(" select TYPE_DESC_ID as \"typeDescId\", TYPE_DESC_NAME as \"typeDescName\" from Sys_Dict_d d,sys_dict h where h.type_id=d.type_id", SysDictD.class);
for (int i = 0; i < list.size(); i++) {
SysDictD sysDictD = (SysDictD) list.get(i);
tableComent.put(sysDictD.getTypeDescId(),sysDictD.getTypeDescName());
}
}
JSP中：
<%@ page import="com.gzlt.framework.cache.CacheManager" %>
CacheManager cm = new CacheManager();
WebInfoD webInfoD = (WebInfoD) cm.tableComent;
out.println(cm.tableComent.get("402881c9405be55f01405c12f8240003"));
