有两个表，student（person id，addressid），address（addressid）
StudentPo类：
package com.lovo.po;
public class StudentPo {
private int personid;
private AddressPo address;
public int getPersonid() {
return personid;
}
public void setPersonid(int personid) {
this.personid = personid;
}
public AddressPo getAddress() {
return address;
}
public void setAddress(AddressPo address) {
this.address = address;
}
}
AddressPo类：
package com.lovo.po;
public class AddressPo {
private int addressid;
public int getAddressid() {
return addressid;
}
public void setAddressid(int addressid) {
this.addressid = addressid;
}
}
