primary auto increment for MySQL

[urswag]

Hello

How will be generated an autoincrement primary key in MySQL?

public class User {

...
@Id
@NotNull
@GeneratedValue
public Long getUserid() {

return userid;
}

public void setUserid() {

this.userid = userid;
}
}

the generated MySQL table is

REATE TABLE `ramschladen`.`user` (
`userid` bigint(20) NOT NULL,
`username` varchar(15) NOT NULL,
`name` varchar(100) NOT NULL,
`password` varchar(15) NOT NULL,
PRIMARY KEY (`username`)
)

userid has no auto_increment specification in MySQL. What shall I do?

You'll have a better chance of getting a helpful response if you ask your question on the Hibernate or EJB3 forums.

It is dummy mistake. I have to use long type and not the Long class. This helps.

@Id
@GeneratedValue
public long getUserid() {

return userid;
}

public void setUserid(long userid) {

this.userid = userid;
}
