बीन वैलिडेशन रिलेशनल बाधाओं को लागू करने में त्रुटि के साथ कैसे निपटें?

Question

मुझे स्प्रिंग + हाइबरनेट 4.1 एप्लिकेशन में एक टॉमी संबंध बनाने में कुछ समस्याएं आई हैं यह मेरी संस्था वर्ग है। प्रत्येक USER_ROLE रिकॉर्ड में उपयोगकर्ता रिकॉर्ड के लिए एफके है। मुझे इंटरनेट पर कुछ भी उपयोगी नहीं मिल रहा है।

@Entity 
@Table(name = "USERS") 
public class User { 

    long id; 
    String login; 
    String password; 
    String name; 
    String surname; 
    GregorianCalendar birthDate; 
    String email; 
    GregorianCalendar joinDate; 
    String randomKey; 
    List<UserRole> userRoles = new ArrayList<UserRole>(); 

    public User(){ } //JavaBean Hibernate requirement 

    @Id 
    @GeneratedValue(generator="increment") 
    @GenericGenerator(name="increment", strategy = "increment") 
    @Column(name="USER_ID", unique=true, nullable=false) 
    public long getId() { 
     return id; 
    } 

    public void setId(long id) { 
     this.id = id; 
    } 
... 

    @OneToMany(mappedBy = "user", fetch = FetchType.LAZY) 
    public List<UserRole> getUserRoles() { 
     return userRoles; 
    } 

    public void setAccountRole(List<UserRole> aUserRoles) { 
     for (UserRole role : aUserRoles) { 
      this.addUserRole(role); 
     } 
    } 

    public void addUserRole(UserRole aRole) { 
     if (!this.userRoles.contains(aRole)) { 
      aRole.setUser(this); 
      this.userRoles.add(aRole); 
     } 
    } 
} 


@Entity 
@Table(name = "USER_ROLE") 
public class UserRole { 

    Integer roleId; 
    String role; 
    User user; 

    public UserRole() { } 

// public UserRole(String role) { 
//  this.setRole(role); 
// } 

    @Id 
    @GeneratedValue(generator="increment") 
    @GenericGenerator(name="increment", strategy = "increment") 
    @Column(name = "ROLE_ID", unique = true, nullable = false) 
    public Integer getRoleId() { 
     return roleId; 
    } 

    public void setRoleId(Integer roleId) { 
     this.roleId = roleId; 
    } 

    @Basic 
    public String getRole() { 
     return role; 
    } 

    public void setRole(String role) { 
     this.role = role; 
    } 

    @ManyToOne(fetch = FetchType.LAZY) 
    @JoinColumn(name = "USER_ID", nullable = false) 
    public User getUser() { 
     return user; 
    } 

    public void setUser(User aUser) { 
     this.user = aUser; 
    } 
} 

और ये मेरे स्टैक ट्रेस में पहली अपवाद है:

Answer 1

वसंत में config हाइबरनेट को validation.mode जोड़ने का प्रयास करें - कोई नहीं:

<bean id="sessionFactory" 
     class="org.springframework.orm.hibernate4.LocalSessionFactoryBean"> 
    <property name="dataSource" ref="dataSource" /> 
    <property name="hibernateProperties"> 
     <props> 
      .... 
      <prop key="javax.persistence.validation.mode">none</prop> 
     </props> 
    </property> 
</bean> 

Answer 2

मैं नहीं कर रहा हूँ वसंत का उपयोग करके और मैं हाइबरनेट 4.1.8 का उपयोग कर रहा हूं और मेरे hibernate.cfg.xml में जोड़ने में काम करता है:

<property name="javax.persistence.validation.mode">none</property> 

Answer 3

JPA और हाइबरनेट का उपयोग करते हुए मुझे persistence.xml को जोड़ने के लिए काम करता है:

<property name="javax.persistence.validation.mode" value="none"/>
