Add default value to column in hibernate

private boolean invalid=false;

@Column(name="INVALID", columnDefinition = "BIT(1) default 0")
public boolean isInvalid() {
return invalid;
}
public void setInvalid(boolean invalid) {
this.invalid = invalid;
}

Should work for mysql only.

}

@After
public void tearDown() {

}

@Test
public void test() {
testDao.callyourmethod();

}
}
