【问题描述】：
我有一个应用程序在 50 个域类中使用 bean 验证。在 Spring MVC 控制器中使用 @Valid 已经工作了几个月，没有任何问题。
现在突然之间，我在 Hibernate 中让许多字段“懒惰”以提高性能。我不得不处理各种奇怪的问题，从 equals() 方法不再工作，到会话中的对象因为数据未加载而崩溃。
我现在遇到了一个非常奇怪的问题，我 am 将数据加载到 Spring MVC 表单上的会话属性中，视图会正确呈现它，但是当传递给 @Valid 时，它会报告即使数据 100% 有效，所有字段都有错误。
public class EducationFacility extends DomainObject {
/* Members */
@NotEmpty(message = "{educationFacility.name.notEmpty}")
private String name;
@Valid
private Address address = new Address();
@Pattern(message = "{educationFacility.phoneNumber.valid}",
regexp = "(\\()?(\\d){3}(\\))?(\\s|-)(\\d){3}(\\s|-)(\\d){4}")
private String phoneNumber = "";
...
}
这是休眠的定义：
<class name="jobprep.domain.educationfacility.EducationFacility" table="education_facility">
<id name="id" column="education_facility_id" type="long">
<generator class="native" />
</id>
<property name="name" column="name"/>
<component name="address" class="jobprep.domain.educationfacility.Address">
<property name="address" column="address"/>
<property name="postalCode" column="postal_code"/>
<many-to-one name="province" class="jobprep.domain.educationfacility.Province" column="province_id" />
</component>
<property name="phoneNumber" column="phone_number"/>
<property name="isEnabled" column="is_enabled"/>
<property name="homepageViewable" column="homepage_viewable" />
<property name="coursesCreated" />
<many-to-one name="admin" class="jobprep.domain.user.Admin" column="admin_id" />
<many-to-one name="director" class="jobprep.domain.educationfacility.Director"
column="director_id" cascade="all" />
<bag name="teachers" inverse="true" cascade="all-delete-orphan" order-by="username asc">
<key column="education_facility_id" />
<one-to-many class="jobprep.domain.teacher.Teacher" />
</bag>
<bag name="students" inverse="true" cascade="all-delete-orphan" order-by="username asc">
<key column="student_education_facility_id" />
<one-to-many class="jobprep.domain.student.Student"/>
</bag>
<bag name="ipRestrictions" inverse="true" cascade="all-delete-orphan">
<key column="education_facility_id" />
<one-to-many class="jobprep.domain.educationfacility.IpRestriction" />
</bag>
<bag name="allowedModules" table="education_facility_to_module"
inverse="false" lazy="true">
<key column="education_facility_id" />
<many-to-many class="jobprep.domain.module.Module" column="module_id"/>
</bag>
</class>
这是控制器定义：
@Controller
@RequestMapping("/myEducationFacility")
@SessionAttributes("educationFacility")
@PreAuthorize("hasRole('ROLE_DIRECTOR')")
public class MyEducationFacilityController extends ControllerSupport {
....
}
这是 MVC 的保存方法：
@RequestMapping(value = "/save", method = RequestMethod.POST)
public String save(@Valid EducationFacility educationFacility, BindingResult result, SessionStatus status) {
if(result.hasErrors()) {
return view("index");
} else {
adminService.saveEducationFacility(educationFacility);
status.setComplete();
return redirect("?complete=true");
}
}
当 Spring 调用 save() 时，Spring is added to binding 结果中的错误如下。这些是完全错误的：
{org.springframework.validation.BindingResult.educationFacility=org.springframework.validation.BeanPropertyBindingResult: 4 errors
Field error in object 'educationFacility' on field 'phoneNumber': rejected value [(519) 254-3678]; codes [Pattern.educationFacility.phoneNumber,Pattern.phoneNumber,Pattern.java.lang.String,Pattern]; arguments [org.springframework.context.support.DefaultMessageSourceResolvable: codes [educationFacility.phoneNumber,phoneNumber]; arguments []; default message [phoneNumber],[Ljavax.validation.constraints.Pattern$Flag;@29895454,(\()?(\d){3}(\))?(\s|-)(\d){3}(\s|-)(\d){4}]; default message [Must be of the form: ###-###-####]
