我有一個應用程序在50個域類中使用bean驗證。它已經在Spring MVC控制器中使用@Valid幾個月沒有任何問題。Spring MVC怪異問題，使用@Valid和Hibernate進行Bean驗證
現在突然之間，我在Hibernate中做了許多「懶」字段來提高性能。我不得不處理各種奇怪的問題，從equals（）方法不再有效，因爲數據未加載而導致會話崩潰的對象。
我遇到了一個非常奇怪的問題，現在我將這些數據加載到Spring MVC表單上的會話屬性中，視圖正確呈現它，但是當傳遞給@Valid時，它會報告所有字段即使數據是100％有效的，也有錯誤。
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 = "";
...
}
這裏是休眠的定義：
<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>
這裏的控制器定義：
@Controller
@RequestMapping("/myEducationFacility")
@SessionAttributes("educationFacility")
@PreAuthorize("hasRole('ROLE_DIRECTOR')")
public class MyEducationFacilityController extends ControllerSupport {
....
}
這裏的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");
}
}
這裏的春天增加了錯誤到bindi當save（）被Spring調用時的結果。這些是完全錯誤的：
{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: ###-###-####]

幫助？
我會試試看。這很奇怪，因爲在另外兩種形式中，@Valid實際上是工作的（教育設施註冊，以及管理員向系統添加/編輯新的教育設施時）。只有當導演編輯自己的教育設施時，它纔會報告錯誤的錯誤。是的，我確保調用服務層並將其加載到數據庫外 - 不使用當前用戶會話中的那個。這種東西背後令人沮喪，並且讓我想要徹底拋出休眠。 – egervari 2010-12-02 17:19:56
