Java 如何防止验证器以不相关的ModelAttribute为目标？

我正在使用Spring框架的定制验证器来验证员工实体的用户输入。若并没有错误，我想直接转到一个html页面，让用户创建一个新的记录

控制器：

@Autowired
私人雇员验证器；
@InitBinder
受保护的活页夹（WebDataBinder活页夹）{
活页夹。添加验证器（eValidator）；
}
@RequestMapping（path=“/authenticate”，method=RequestMethod.POST）
公共模型和视图身份验证（@Valid@modeldattribute Employee user，BindingResult BindingResult）{
if（bindingResult.hasErrors（））{
返回新的ModelAndView（“重定向：/”）；
}
ModelAndView mav=新的ModelAndView（“离开表单”）；
mav.addObject（“leave”，new LeaveRecord（））；
返回mav；
}

验证器：

@Component
public class EmployeeValidator implements Validator{

    private LeaveServiceIF lService;

    @Autowired
    public void setlService(LeaveServiceIF lService) {
        this.lService = lService;
    }

    @Override
    public boolean supports(Class<?> clazz) {
        return Employee.class.equals(clazz);
    }

    @Override
    public void validate(Object obj, Errors e) {
        Employee emp = (Employee) obj;
        if (lService.authenticate(emp.getEmpId(), emp.getPwd()) == null) {
            e.rejectValue(null, "invalidEmpIdOrPwd");
        }
    }
}

看起来EmployeeValidator的目标是我传递给html视图的LeaveRecord实体，因此导致了异常

有没有办法防止这种情况发生，或者我做得对吗？

您的验证器类似乎有问题。你能告诉我们密码吗

这可能有助于：

这很奇怪，我觉得一切都很好。请发布所有Spring依赖项的确切版本（大部分应该是相同的）和您的验证器。还包括您的整个堆栈跟踪，以便我们可以看到从何处调用不正确的验证。@chrylis我已添加了验证程序、依赖项和堆栈跟踪。谢谢你的帮助@chrylis我的问题已经解决了，似乎我需要在InitBinder注释中添加一个值，这样验证器将只应用于Employee classAha的模型属性，

@Valid

的默认假设是您正在使用现成的Bean验证验证器。注意，使用现场注入被认为是不可取的；构造函数注入使代码更易于测试，也不太可能出现某些类型的错误。一般来说，验证用于确认对象引用的记录的值都是合法的（例如，ID和密码不是空的），但通常不会检查它们是否与数据库记录对应。在更简单的情况下，有一个框架已经为您准备好了。还请注意，您似乎正在尝试重新设计会话安全性，这是一个坏主意；如果您可以避免手动处理安全性问题，那么只需使用Spring安全性。我尝试在InitBinder注释中添加一个值，即@InitBinder（“用户”），结果成功了。谢谢如果我对官方文档的理解没有错误，那么默认情况下，如果没有提供值，InitBinder会将验证器应用于所有模型属性吗？基于您链接的文章，所以如果我使用@InitBinder（“employee”），那么验证器应该只应用于所有employee实体，而不管model属性的名称是什么？e、 g.本方法中的“用户”，另一种方法中的“管理者”
