電子郵件型號：

import javax.validation.constraints.NotNull; 
import javax.validation.constraints.Size; 

import org.hibernate.validator.constraints.NotEmpty; 

public class EmailReqInfo 
{ 

    @NotNull @NotEmpty 
    @Size(min=1) 
    private String emailSubject; 
    @NotNull @NotEmpty 
    private String emailMsg; 
    public String getEmailSubject() { 
     return emailSubject; 
    } 
    public void setEmailSubject(String emailSubject) { 
     this.emailSubject = emailSubject; 
    } 
    public String getEmailMsg() { 
     return emailMsg; 
    } 
    public void setEmailMsg(String emailMsg) { 
     this.emailMsg = emailMsg; 
    } 
}

我有必要的註釋在我的彈簧mvc.xml在固定validation..thanks

什麼是領域的錯誤是你在綁定結果？你能發帖 – Saravana

HI Sarvana，我沒有得到任何錯誤，即使我發送空輸入到模型，result.hasErrors（）總是返回false，所以它沒有進入if條件..我沒有看到任何錯誤..任何想法，我錯了.. –

@NotNull需要

<mvc:annotation-driven> 
    <mvc:message-converters register-defaults="false"> 
    <bean id="jacksonMessageConverter" 
     class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter"/> 
    </mvc:message-converters> 
    </mvc:annotation-driven>

幫助：檢查值是否不爲空，忽略內容。

@NotEmpty：檢查值是否不爲空也不爲空。如果它只有空的空間，它將允許它不空。

@NotBlank：檢查值是否不爲空也不爲空，先修剪值。這意味着，它不會允許只是空的空間

所以，如果你想驗證一個字段不是空的，但它也沒有隻是空的空間，但文本，你應該使用@NotBlank 。

這個例子是工作，嘗試做相同的：

實體：

@Entity 
@Table(name="EMPLOYEE") 
public class Employee { 

    @Id 
    @GeneratedValue(strategy = GenerationType.IDENTITY) 
    private int id; 

    @Size(min=3, max=50) 
    @Column(name = "NAME", nullable = false) 
    private String name; 

    @NotNull 
    @DateTimeFormat(pattern="dd/MM/yyyy") 
    @Column(name = "JOINING_DATE", nullable = false) 
    @Type(type="org.jadira.usertype.dateandtime.joda.PersistentLocalDate") 
    private LocalDate joiningDate; 

    @NotNull 
    @Digits(integer=8, fraction=2) 
    @Column(name = "SALARY", nullable = false) 
    private BigDecimal salary; 

    @NotEmpty 
    @Column(name = "SSN", unique=true, nullable = false) 
    private String ssn; 
//getter & setter 
}

控制器：

@RequestMapping(value = { "/new" }, method = RequestMethod.POST) 
    public String saveEmployee(@Valid Employee employee, BindingResult result, 
      ModelMap model) { 

     if (result.hasErrors()) { 
      return "registration"; 
     } 


     service.saveEmployee(employee); 

     model.addAttribute("success", "Employee " + employee.getName() + " registered successfully"); 
     return "success"; 
    }

registation.jsp

<h2>Registration Form</h2> 

    <form:form method="POST" modelAttribute="employee"> 
     <form:input type="hidden" path="id" id="id"/> 
     <table> 
      <tr> 
       <td><label for="name">Name: </label> </td> 
       <td><form:input path="name" id="name"/></td> 
       <td><form:errors path="name" cssClass="error"/></td> 
      </tr> 

      <tr> 
       <td><label for="joiningDate">Joining Date: </label> </td> 
       <td><form:input path="joiningDate" id="joiningDate"/></td> 
       <td><form:errors path="joiningDate" cssClass="error"/></td> 
      </tr> 

      <tr> 
       <td><label for="salary">Salary: </label> </td> 
       <td><form:input path="salary" id="salary"/></td> 
       <td><form:errors path="salary" cssClass="error"/></td> 
      </tr> 

      <tr> 
       <td><label for="ssn">SSN: </label> </td> 
       <td><form:input path="ssn" id="ssn"/></td> 
       <td><form:errors path="ssn" cssClass="error"/></td> 
      </tr> 

      <tr> 
       <td colspan="3"> 
        <c:choose> 
         <c:when test="${edit}"> 
          <input type="submit" value="Update"/> 
         </c:when> 
         <c:otherwise> 
          <input type="submit" value="Register"/> 
         </c:otherwise>

我看到Hibernate Validators的問題。 @NotEmpty無論如何都是在@NotNull之上。

嘗試從表單中刪除@NotEmpty驗證約束並再次執行。
