Yes - #handleby.id# will turn into getHandleby().getId().  No need to ask this question again.

 

Some comments on your example:

 

1. All your fields are private, and you have public accessors.  This could be the problem.

 

2. parameterClass must be a fully qualified class name.  You've example shows parameterClass="account" - but I think that "account" is not the fully qualified class name.  This could be the problem.

 

If your example is truly as you've posted, it will never work.  The first thing I would try is to turn the parameterClass into the correct class name, and add some public getters/setters.

No,Patel

     that is not what i want.

     I dont like to get handleby user id manually , you know , handleby attribute of Account is type of User, not Long or Integer.

    i'd like to use my pojo in oo way ,not face to persistent field directly. 

    what i want to know is whether ibatis can work just like OGNL ,and this still is the key point, does #handleby.id# will be auto unwrapped in getHandleby().getId() way.

 

thanks anymore.

 

is cliniton there? show me the way please.

If this enough?

 

POJO:
public class Account implements Serializable {
 private Long id;
 private String name;
 private Double deposit;
 private User handleby; Ur wrong here
}  

 public class User implements Serializable {
 private Long id;

 SQL:
 <insert id="insertAccount" parameterClass="account">
insert into ACCOUNT (ID,NAME, DEPOSITE, FK_HANDLEBY)

Client Call sample (planned):

 

Account account = new Account();

account.setName("testAccount");

account.setDeposit(new Double(0.0));

User user = UserService.getUserByID(new Long(1));//get prepared user object------Ur wrong here

Hi Alex,

 

POJO:
public class Account implements Serializable {
 private Long id;
 private String name;
 private Double deposit;
 private int handleby; //modified
}  

 public class User implements Serializable {
 private Long id;
 private String username;
 private String password;
}

 SQL:
 <insert id="insertAccount" parameterClass="account">
insert into ACCOUNT (ID,NAME, DEPOSITE, FK_HANDLEBY)
values (#id#, #name#, #deposit#, #handleby#)
</insert>

 

 <insert id="insertUser" parameterClass="user">
insert into USER(ID,NAME, PASSWORD)
values (#id#, #name#, #password#)
</insert>

 

DDL(MySQL):
CREATE TABLE USER (
ID BIGINT NOT NULL,
NAME VARCHAR(255) ,
PASSWORD VARCHAR(255)
);

 

CREATE TABLE ACCOUNT(
ID BIGINT NOT NULL,
NAME VARCHAR(255) ,
DEPOSIT DOUBLE,

FK_HANDLEBY BIGINT
);

 

DAO:

AccountDao:

createAccount(Account account)

{

  //get id and set to account

  insert("insertAccount",account);

}

 

UserDao:

createUser(User user)

{

  //get id and set to user

  insert("insertUser",user);

}

 

Service:

AccountService:

createNewAccount(Account account)

{

  //transaction ignored

  DaoManager.getAccountDao().createAccount(account);

}

 

Client Call sample (planned):

 

Account account = new Account();

account.setName("testAccount");

account.setDeposit(new Double(0.0));

 

int handlebyid = UserService.getUserByID();

account.setHandleby(handlebyid );

AccountService.createNewAccount(account);

 

Now it'll works.

 

 

Tx,

 

Patel.
