我正在使用Spring v3.2.6，Hibernate v4.2.2。
这是我的SecurityUser对象：

当我单击在Controller类中调用以下方法的URL时发生错误：
@RequestMapping(produces = "text/html")
public String list(

final int firstResult = page == null ? 0 : (page.intValue() - 1) * sizeNo;
uiModel.addAttribute("securityusers", securityUserService.findSecurityUserEntries(firstResult, sizeNo));
float nrOfPages = (float) securityUserService.countAllSecurityUsers() / sizeNo;
uiModel.addAttribute("maxPages", (int) ((nrOfPages > (int) nrOfPages || nrOfPages == 0.0) ? nrOfPages + 1 : nrOfPages));
}
else {
uiModel.addAttribute("securityusers", securityUserService.findAllSecurityUsers());
}
return "securityusers/list";
}
有人可以帮忙解决这个问题吗？
