这是把数据库中一张表的部分信息添加到另外一张表上
代码如下
public ModelAndView queryAll(HttpServletRequest request,HttpServletResponse response){
ModelAndView mnv = new ModelAndView(getIndexView());
Yx_tzshjmb yx_tzshjmb = null;
List list = yx_zhsjbService.queryAll();
for (Yx_zhsjb yx_zhsjb : list) {
yx_tzshjmbService.save(yx_tzshjmb,yx_zhsjb);
}
return mnv;
}
service层
public void save(Yx_tzshjmb yx_tzshjmb,Yx_zhsjb yx_zhsjb) {
yxxt.utils.DESUtil desUtil = new yxxt.utils.DESUtil();
yx_tzshjmb.setNd(yx_zhsjb.getNd());
yx_tzshjmb.setXm(yx_zhsjb.getXm());
yx_tzshjmb.setTzsh(yx_zhsjb.getTzsh());
然后添加这块就出错了
