Hibernate Mapping and Many to One example - part 2

This is a continuation of Hibernate Mapping and Many to One example - part 1.

Step 5: Define the previously mapped classes UserApp and UserAppId in persistence.xml file along with the other classes that will be mapped below.

<?xml version="1.0" encoding="UTF-8"?>
<persistence version="1.0"
 xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd">
 <persistence-unit name="myapp">

  
  <class>com.jpmorgan.myapp.model.security.CmnUser</class>
  
  <class>com.jpmorgan.myapp.model.security.UserApp</class>
  <class>com.jpmorgan.myapp.model.security.UserAppId</class>
  
  <class>com.jpmorgan.myapp.model.security.User</class>
  <class>com.jpmorgan.myapp.model.security.App</class>
  
 
  <exclude-unlisted-classes>true</exclude-unlisted-classes>

  <properties>
   <property name="hibernate.dialect"
    value="org.hibernate.dialect.SybaseASE15Dialect" />
   <property name="hibernate.show_sql" value="true" />
   <property name="hibernate.cache.use_second_level_cache"
    value="false" />
  </properties>

 </persistence-unit>
</persistence>

Step 6: Mapping of User table.

import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.Table;

@SuppressWarnings("serial")
@Entity
@Table(name = "User", schema = "dbo", catalog = "my_app")
public class User implements java.io.Serializable
{
    
    private String userName;
    private char disabled;
    private String comment;
    private char status;
    private Date createdOn;
    private String createdBy;
    private Date modifiedOn;
    private String modifiedBy;
    private byte[] timestamp;
    
    public User()
    {
    }
    
    public User(String userName,char disabled, char status, Date createdOn, String createdBy,

    }
    
       
    @Id
    @Column(name = "UserName", unique = true, nullable = false, length = 40)
    public String getUserName()
    {
        return this.userName;
    }
    
    public void setUserName(String userName)
    {

    }
    
    @Column(name = "UserType", nullable = false, length = 40)
    public String getUserType()
    {
        return this.userType;
    }
    
    public void setUserType(String userType)
    {
        this.userType = userType;
    }
    
    @Column(name = "Disabled", nullable = false, length = 1)
    public char getDisabled()
    {
        return this.disabled;
    }
    
    public void setDisabled(char disabled)
    {
        this.disabled = disabled;
    }
    
 
    @Column(name = "Comment")

    }
    
    @Column(name = "Status", nullable = false, length = 1)
    public char getStatus()
    {
        return this.status;
    }
    
    public void setStatus(char status)
    {
        this.status = status;
    }
    
    @Temporal(TemporalType.TIMESTAMP)
    @Column(name = "CreatedOn", nullable = false, length = 23)
    public Date getCreatedOn()
    {
        return this.createdOn;
    }
    
    public void setCreatedOn(Date createdOn)
    {
        this.createdOn = createdOn;
    }
    
    @Column(name = "CreatedBy", nullable = false, length = 40)
    public String getCreatedBy()
    {
        return this.createdBy;
    }
    
    public void setCreatedBy(String createdBy)
    {
        this.createdBy = createdBy;
    }
    
    @Temporal(TemporalType.TIMESTAMP)
    @Column(name = "ModifiedOn", nullable = false, length = 23)
    public Date getModifiedOn()
    {
        return this.modifiedOn;
    }
    
    public void setModifiedOn(Date modifiedOn)
    {
        this.modifiedOn = modifiedOn;
    }
    
    @Column(name = "ModifiedBy", nullable = false, length = 40)
    public String getModifiedBy()

    public void setModifiedBy(String modifiedBy)
    {
        this.modifiedBy = modifiedBy;
    }
    
    @Version
    @Column(name = "Timestamp", insertable = false, updatable = false, unique = true, nullable = false)
    @Generated(GenerationTime.ALWAYS)
    public byte[] getTimestamp()
    {
        return this.timestamp;
    }
    
    public void setTimestamp(byte[] timestamp)
    {
        this.timestamp = timestamp;
    } 
}

Step 7: Mapping of App table.

package com.myapp.model.security;

import java.util.Date;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.Table;
import javax.persistence.Temporal;
import javax.persistence.TemporalType;
import javax.persistence.Version;

import org.hibernate.annotations.Generated;
import org.hibernate.annotations.GenerationTime;

@SuppressWarnings("serial")
@Entity
@Table(name = "App", schema = "dbo", catalog = "sne_kath")
public class App implements java.io.Serializable
{
    
    private String appCd;
    private String description;
    private char status;
    private char disabled;
    private Date createdOn;
    private String createdBy;
    private Date modifiedOn;
    private String modifiedBy;
    private byte[] timestamp;
    private String requiresDeskTop;
    
    public App()
    {
    }
    
    public App(String appCd, String description, char status, Date createdOn, String createdBy, Date modifiedOn,
            String modifiedBy)
    {
        this.appCd = appCd;
        this.description = description;
        this.status = status;
        this.createdOn = createdOn;
        this.createdBy = createdBy;
        this.modifiedOn = modifiedOn;
        this.modifiedBy = modifiedBy;
    }
    
    @Column(name = "appcd", nullable = false)
    @Id

    }
    
    @Column(name = "description", nullable = false)
    public String getDescription()
    {
        return description;
    }
    
    public void setDescription(String description)
    {
        this.description = description;
    }
    
    public char getDisabled()
    {
        return disabled;
    }
    
    public void setDisabled(char disabled)
    {
        this.disabled = disabled;
    }
    
    @Column(name = "RequiresDesktop", nullable = true)
    public String getRequiresDeskTop()
    {
        return requiresDeskTop;
    }
    
    public void setRequiresDeskTop(String requiresDeskTop)
    {
        this.requiresDeskTop = requiresDeskTop;
    }
    
    @Version
    @Column(name = "Timestamp", insertable = false, updatable = false, unique = true, nullable = false)
    @Generated(GenerationTime.ALWAYS)
    public byte[] getTimestamp()
    {
        return this.timestamp;
    }
    
    public void setTimestamp(byte[] timestamp)
    {
        this.timestamp = timestamp;
    }
    
    @Column(name = "Status", nullable = false, length = 1)
    public char getStatus()
    {
        return this.status;
    }
    
    public void setStatus(char status)
    {
        this.status = status;
    }
    
    @Temporal(TemporalType.TIMESTAMP)
    @Column(name = "CreatedOn", nullable = false, length = 23)
    public Date getCreatedOn()
    {
        return this.createdOn;
    }
    
    public void setCreatedOn(Date createdOn)
    {
        this.createdOn = createdOn;
    }
    
    @Column(name = "CreatedBy", nullable = false, length = 40)
    public String getCreatedBy()
    {
        return this.createdBy;
    }
    
    public void setCreatedBy(String createdBy)
    {
        this.createdBy = createdBy;
    }
    
    @Temporal(TemporalType.TIMESTAMP)
    @Column(name = "ModifiedOn", nullable = false, length = 23)
    public Date getModifiedOn()
    {
        return this.modifiedOn;
    }
    
    public void setModifiedOn(Date modifiedOn)
    {
        this.modifiedOn = modifiedOn;
    }
    
    @Column(name = "ModifiedBy", nullable = false, length = 40)
    public String getModifiedBy()
    {
        return this.modifiedBy;
    }
    
    public void setModifiedBy(String modifiedBy)
    {
        this.modifiedBy = modifiedBy;
    } 
}

Step 8: Finally, the hibernate and JPA dependency jars in Maven's pom.xml file.
