在Hibernate中进行OneTONE映射时，如何更新数据库中的数据？

我有一个用户类，它包含一个带有OneToOne映射的address，当我试图运行它时，它并没有将数据插入到db（Postgres）中，我也没有得到任何错误

package com.hibernate.sample;

import javax.persistence.CascadeType;
import javax.persistence.Column;
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.OneToOne;
import javax.persistence.Table;
@Table(name="Siva01")
@Entity
public class UserClass {
   @Id  
   @GeneratedValue(strategy=GenerationType.AUTO)
   @Column(name = "UserId") 
   private int id ; 
   @Column(name = "UserName")
   private String userName;
   @OneToOne(cascade=CascadeType.PERSIST)
   @JoinColumn(name="AddressId")
   private Address shippingAddress; 


public Address getShippingAddress() {
    return shippingAddress;
}
public void setShippingAddress(Address shippingAddress) {
    this.shippingAddress = shippingAddress;
}
public int getId() {
    return id;
}
public void setId(int id) {
    this.id = id;
}
public String getUserName() {
    return userName;
}
public void setUserName(String userName) {
    this.userName = userName;
} 
}

地址类别：

package com.hibernate.sample;

import javax.annotation.Generated;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;

@Entity
public class Address {
    @Id
    @GeneratedValue(strategy=GenerationType.AUTO)
    private int id; 
    private String StreetName;
    private String city;
    public int getId() {
        return id;
    }
    public void setId(int id) {
        this.id = id;
    }
    public String getStreetName() {
        return StreetName;
    }
    public void setStreetName(String streetName) {
        StreetName = streetName;
    }
    public String getCity() {
        return city;
    }
    public void setCity(String city) {
        this.city = city;
    } 
}

请说明我在上述代码中出错的地方。

update将数据插入数据库的代码和为此生成的相应日志在哪里？能否显示插入数据的代码片段？@Chaitanya-我添加了插入代码
