I am using

hibernate 3.2.5.ga
hibernate-annotations 3.3.1.ga
hibernate-commons-annotations 3.3.0.ga
spring 3.1.1
MySQL 5

This should be a very simple case, but I think I am missing something obvious. I have a User table and a UserRole table – without a foreign key.
I have the following entities:

@Entity
@Table(name = "User", catalog = "mcp", uniqueConstraints = { @UniqueConstraint(columnNames = "UserName") })
public class User implements Serializable {

    // Fields
    @Id
    @Column(name = "UserId", unique = true, nullable = false)
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long userId;

    @Column(name = "Status", length = 50)
    private Integer status = 0;

    @Column(name = "Password", length = 45)
    private String password;
    @Column(name = "UserName", unique = true, length = 50)
    private String userName;

    @OneToOne
    private UserRole userRole;
.. getters & setters()...
}

and

@Entity
@Table(name = "UserRole", catalog = "mcp")
public class UserRole implements Serializable {

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

    @Column(name = "UserRoleDescriptionShort", length = 45)
    private String userRoleDescriptionShort;

    @Column(name = "UserRoleDescription", length = 200)
    private String userRoleDescription;
.. getters & setters()...
}

However, when I try to build, I get this:

Caused by: org.hibernate.HibernateException: Missing column: userRole_Id in mcp.User

So my question is, is this a good strategy for Hibernate/Spring? Should I allow Hibernate to manage the relationships as above, or if I should I modify User table to have a “userRoleId” that holds the value from UserRole table? If so, what would that look like.

sonoerin,

Firstly, do you have a column “Id” in the user role table ? Ideally you should have a foreign key constraint between the two tables.

It might also be an issue with user permissions. Take a look at this link :
https://forum.hibernate.org/viewtopic.php?f=1&t=995850

I suggest you cross post to Hibernate development forums for better support as this is a Hibernate question rather than a MyEclipse one.

Hope this helps.

I should have mentioned I am developing this in MyEclipse:
Version: 10.5
Build id: 10.5-20120615

I have setup a side/test project for mapping of this. Here are the dependencies:

<spring.version>3.1.1.RELEASE</spring.version>
<hibernate.version>3.4.0.GA</hibernate.version>
<mysql.connector.version>5.1.21</mysql.connector.version>
<hsql.version>1.8.0.10</hsql.version>

I am just trying to get a unit test going using HSQL for now. Is there a standard way to test Hibernate/Spring ? Each time I create a test I get the previous error message, so I must be doing something wrong, even though this is about as simple of a @OneToOne example as there is (except for the lack of a foreign key).
