我在Grails應用程序中使用Java實體類作爲域對象。這些類具有JSR 303驗證註釋(@Size,@NotEmpty等)。Grails:如何處理JSR 303 bean驗證
的Grails控制器和視圖做工精細與這些實體類,但是當我試圖挽救破碎的制約因素的實例(@NotEmpty字段爲空值),我得到一個錯誤頁面如下:
/webcall-account-manager-2/company/save
Class
javax.validation.ConstraintViolationException
Message
Validation failed for classes [com.rcslabs.webcall.server.model.Company] during persist time for groups [javax.validation.groups.Default, ] List of constraint violations:[ ConstraintViolationImpl{interpolatedMessage='may not be empty', propertyPath=name, rootBeanClass=class com.rcslabs.webcall.server.model.Company, messageTemplate='{org.hibernate.validator.constraints.NotBlank.message}'} ]
Around line 27 of grails-app/controllers/com/rcslabs/webcall/server/model/CompanyController.groovy

25: def companyInstance = new Company()
26: companyInstance.properties = params
27: if (!companyInstance.save(flush: true)) {
28: render(view: "create", model: [companyInstance: companyInstance])
29: return
30: }

怎樣才能以正確的方式處理它(字段上方的消息框)?
