My New Project is in Hibernate 4.2.5.Final and Spring. After Login, I am storing the user object in the session. Now after successful login, I need to insert one record in the application log. Here are the classes:
Code:
@MappedSuperclass
public abstract class BaseEntity implements Serializable {
private static final long serialVersionUID = 1L;
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private long ID;
@Version
private Long version;
private Long createdBy;
@Temporal(value = TemporalType.TIMESTAMP)
private Date createdDate;
private Long updatedBy;
@Temporal(value = TemporalType.TIMESTAMP)
private Date updatedDate;
private String deactivatedReason;
private String activatedReason;
private Integer active;
public long getID() {
return ID;
}
public void setID(long iD) {
ID = iD;
}
public Long getVersion() {
return version;
}
public void setVersion(Long version) {
this.version = version;
}
public Long getCreatedBy() {
return createdBy;
}
public void setCreatedBy(Long createdBy) {
this.createdBy = createdBy;
}
public Date getCreatedDate() {
return createdDate;
}
public void setCreatedDate(Date createdDate) {
this.createdDate = createdDate;
}
public Long getUpdatedBy() {
return updatedBy;
}
public void setUpdatedBy(Long updatedBy) {
this.updatedBy = updatedBy;
}
public Date getUpdatedDate() {
return updatedDate;
}
public void setUpdatedDate(Date updatedDate) {
this.updatedDate = updatedDate;
}
public String getDeactivatedReason() {
return deactivatedReason;
}
public void setDeactivatedReason(String deactivatedReason) {
this.deactivatedReason = deactivatedReason;
}
public String getActivatedReason() {
return activatedReason;
}
public void setActivatedReason(String activatedReason) {
this.activatedReason = activatedReason;
}
public Integer getActive() {
return active;
}
public void setActive(Integer active) {
this.active = active;
}
}
Code:
package com.product.domain;
import javax.persistence.Entity;
import javax.persistence.FetchType;
import javax.persistence.JoinColumn;
import javax.persistence.ManyToOne;
import javax.persistence.NamedQueries;
import javax.persistence.NamedQuery;
import javax.persistence.Table;
import javax.validation.constraints.Pattern;
import org.hibernate.validator.constraints.Email;
import org.hibernate.validator.constraints.NotBlank;
import com.product.audit.IAuditLog;
import com.product.domain.base.BaseEntity;
@Entity
@Table(name = "users")
@NamedQueries({ @NamedQuery(name = "Users.findUserByUserID", query = "SELECT usr FROM Users as usr WHERE usr.userName = ? and usr.practice.code = ?") })
public class Users extends BaseEntity implements IAuditLog {
private String userName;
private String password;
// bi-directional many-to-one association to Practice
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "practiceID")
private Practice practice;
//getters and setters
}
Code:
package com.product.domain;
import java.util.Date;
import javax.persistence.CascadeType;
import javax.persistence.Entity;
import javax.persistence.FetchType;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.JoinColumn;
import javax.persistence.ManyToOne;
import javax.persistence.Table;
import javax.persistence.Temporal;
import javax.persistence.TemporalType;
@Entity
@Table(name = "applicationevents")
public class ApplicationEvents {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private long ID;
@Temporal(value = TemporalType.TIMESTAMP)
private Date eventDate;
private String comments;
private Integer eventType;
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "practiceID")
private Practice practice;
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "userID")
private Users userID;
//getters and setters
}
ApplicationEvents appEvent = new ApplicationEvents();
appEvent.setEventType(eventType);
appEvent.setPractice(practice);
appEvent.setUserID(userID);
appEvent.setComments(comments);
appEvent.setEventDate(new Timestamp(new Date().getTime()));
CRUDService.Save(appEvent);
When I try to save ApplicationEvent, I am getting the following error:
18:34:34.540 [http-bio-8080-exec-8] INFO c.p.a.MyUserDetailsService - Logged User authentication sucess. UserName admin and practice Name Physicians Choice Laboratory

Very Important Note: When I remove the @Version in the base entity, everything works fine
