I have 2 Entities User and AccountBase with a many-to-many relationship. I need to select all AccountBase objects with a selected User ID from the join table. I have tried some join queries but don't work.
@Table(name = "ACCOUNT")
@DiscriminatorColumn(name = "ACCOUNT_TYPE", length = 1)
public abstract class AccountBase extends ModelBase {
protected double balance;
protected List<User> users = new ArrayList<>();
@Table(name = "USER_ACCOUNT")
public class User extends ModelBase implements Serializable {
private static final long serialVersionUID = 1L;
protected String name;
protected List<AccountBase> bankAccounts = new ArrayList<>();
// bi-directional many-to-many association to AccountBase
@ManyToMany
@JoinTable(name = "USER_ACCOUNT_ACCOUNT", joinColumns = { @JoinColumn(name = "USER_ID") }, inverseJoinColumns = {
@JoinColumn(name = "ACCOUNT_ID") })
public List<AccountBase> getBankAccounts() {
return this.bankAccounts;
}
从账户库加入用户实体
select account from AccountBase account join account.users user where user.id=?
