dwz框架下多选删除功能实现

我用的是SpringMVC＋hibernate结合DWZ做的，你说的就是批量删除吗？
这是业务类 public void piLiangDel(String id){
String[] ids = id.split(",");
for(int i=0;i super.removeById(Users.class,ids[i]);
}
}
这是Controler类
@RequestMapping(value="piLiangDel")
public void piLiangDel(HttpServletResponse response,HttpServletRequest request) throws IOException{
String ids = request.getParameter("ids");

try {
usersManager.piLiangDel(ids);
response.getWriter().write(dwzAjaxResult("200","删除成功......！","forward","../security/user/index.spring"));
} catch (Exception e) {
response.getWriter().write(dwzAjaxResult("301","删除失败！"+e.getMessage(),"forward","../security/user/index.spring"));
}

}
