Hibernate Postgresql boolean problems

Question

I have object with boolean field like

@Entity

@Table(name = "USERS")
public class User {

    @Id
    @GeneratedValue
    @Column(name = "ID")
    private Integer id;

    @Column(name = "ACTIVE")
    private Boolean active = true;
}

AND query for creating

CREATE TABLE IF NOT EXISTS USERS(
   ID  SERIAL PRIMARY KEY,
   ACTIVE SMALLINT ,
   LOGIN  CHAR(255) NOT NULL,
   NAME   CHAR(255) NOT NULL,
   PASSWORD CHAR(255) NOT NULL,
   ROLE INTEGER NOT NULL REFERENCES ROLE(ID)
);

When i try to take a user object i have next exception ERROR: operator does not exist: smallint = boolean

Answer 1

In PostgreSQL, SMALLINT maps to Short and BOOLEAN maps to Boolean (hence the name).

You get to decide whether to change the class or the table.

Answer 2

尝试添加：

@Type(type = "org.hibernate.type.NumericBooleanType")
