Hibernate中的component的用法

User类

public class User {


private int id;
private String name;
private ConnectionMapping connectionUser;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public ConnectionMapping getConnectionUser() {
return connectionUser;
}
public void setConnectionUser(ConnectionMapping connectionUser) {
this.connectionUser = connectionUser;
}

}

Employee类

public class Employee {
private int id;
private int age;
private ConnectionMapping connectionEmployee;
public ConnectionMapping getConnectionEmployee() {
return connectionEmployee;
}
public void setConnectionEmployee(ConnectionMapping connectionEmployee) {
this.connectionEmployee = connectionEmployee;
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}

}

Connectionmapping类

public class ConnectionMapping {


private String tel;
private String address;
private String postCode;
public String getTel() {
return tel;
}
public void setTel(String tel) {
this.tel = tel;
}
public String getAddress() {
return address;
}
public void setAddress(String address) {
this.address = address;
}
public String getPostCode() {
return postCode;
}
public void setPostCode(String postCode) {
this.postCode = postCode;
}
}
