[Hibernate-JIRA] Created: (HBX-970) POJO generation should have full contructor as an option

POJO generation should have full contructor as an option
--------------------------------------------------------
Key: HBX-970
URL: http://opensource.atlassian.com/projects/hibernate/browse/HBX-970
Project: Hibernate Tools
Issue Type: Bug
Components: hbm2java, reverse-engineer
Affects Versions: 3.2beta9
Environment: Hibernate3, Oracle 10g
Reporter: Alberto A. Flores
When using hbm2java (for reverse …
[View More]engineering the database to generate POJOs), there is no real way to declare full constructor generation as an option (which is not required in Hibernate anyway). In a large table, I found the error of "can't create a constructor with more than 255 parameters" (which could easily grow if you use inheritance). We had to fix the PojoContructors.ftl code to never generate that full contructor.
Potential fixes:
- Find a way to initialize the BasicPojoClass to initialize the needFullContructor using <property> in the hbm2java
- Using the <property> feature within hbm2java, fix the PojoConstructor.ftl to check for a variable that is (optionally) visible by virtue of the <property> tag instead of always checking for "pojo.needFullConstructor"
- Provide a way to replace BasicPojoClass as part of the hbm2java task. By default, this uses the hardcoded code to always use this template.

Joins break when using composite primary key classes
----------------------------------------------------

Joins break when using composite primary key classes
JBoss 4.0.5.GA w/ Hibernate 3.2.2 and Annoations 3.2.2 (from SVN). Also reproduced w/ JBoss 4.0.5.GA w/ stock annotations, hibernate, and entity manager, unmodified. The attached test-case was run against MSSQL 2000 but is trivial to point at another database. The issue was also reproduced on a OpenEdge Progress 10.1A database.
In a case where there are composite keys on one (or each) side of a relationship, Hibernate cannot join the entities together if all of the primary key fields are not used in the relationship.
A (very) simple example, two entities Carz and Lotz (pardon the names, it's simply cars and car lots):
@Entity
@Table(name="car")
public class Carz implements Serializable
{
@Id
private Integer id;
@Column(name="make", nullable=false)
private String make;
@Column(name="model", nullable=false)
private String model;
@Column(name="manufactured", nullable=false)
@Temporal(TemporalType.TIMESTAMP)
private Date manufactured;
@ManyToOne(fetch=FetchType.LAZY)
@JoinColumns //Hibernate docs state that @JoinColumns must be used since Lotz has composite PK, a single @JoinColumn does not deploy anyhow
({
@JoinColumn(name="loc_code", referencedColumnName="loc_code", insertable=false, updatable=false)
})
private Lotz lot;
...........................
}
@Entity
@Table(name="lot")
public class Lotz implements Serializable
{
@EmbeddedId
protected LotzPK lotPK;
@Column(name="name", nullable=false)
private String name;
@Column(name="location", nullable=false)
private String location;
@OneToMany(mappedBy="lot", fetch=FetchType.LAZY, cascade=CascadeType.ALL)
private List<Carz> cars;
...........................
}
@Embeddable
public class LotzPK implements Serializable
{
@Column(name="id", nullable=false)
private Integer id;
@Column(name="loc_code", nullable=false)
private String locCode;
...........................
}
In this case I need a one-to-many relationship on Carz.id = Lotz.locCode. However, there doesn't appear to be a way to do this.
When this is deployed, this exception occurs:
org.hibernate.AnnotationException: Column name id of hqb.model.Lotz not found in JoinColumns.referencedColumnName

I can deploy the app if I map both fields in the Lotz PK class like so:
@Entity
@Table(name="car")
public class Carz implements Serializable
{
@Id
private Integer id;
...........................
@ManyToOne(fetch=FetchType.LAZY)
@JoinColumns
({
@JoinColumn(name="loc_code", referencedColumnName="loc_code", insertable=false, updatable=false),
@JoinColumn(name="", referencedColumnName="id", insertable=false, updatable=false) //INCORRECTLY DEFINED RELATIONSHIP!
})
private Lotz lot;
...........................
}
But obviously this is no good, it generates bad SQL at runtime:
/* select
c
from
Carz c
left join
fetch c.lot */ select
carz0_.id as id198_0_,
lotz1_.id as id199_1_,
lotz1_.loc_code as loc2_199_1_,
carz0_.make as make198_0_,
carz0_.model as model198_0_,
carz0_.manufactured as manufact4_198_0_,
carz0_.lot_id as lot5_198_0_,
carz0_.loc_code as loc6_198_0_, --no such column...
lotz1_.name as name199_1_,
lotz1_.location as location199_1_
from
car carz0_
left outer join
lot lotz1_
on carz0_.lot_id=lotz1_.id --oops! Hibernate defaulted a relationship here...
and carz0_.loc_code=lotz1_.loc_code
In reality, this is the SQL I'm trying to achieve, by repairing the above query manually:
select
carz0_.id as id198_0_,
lotz1_.id as id199_1_,
lotz1_.loc_code as loc2_199_1_,
carz0_.make as make198_0_,
carz0_.model as model198_0_,
carz0_.manufactured as manufact4_198_0_,
carz0_.loc_code as loc6_198_0_,
lotz1_.name as name199_1_,
lotz1_.location as location199_1_
from
car carz0_
left outer join
lot lotz1_
on carz0_.loc_code=lotz1_.loc_code
This is consistent w/ the EJB 3.0 spec (and Glassfish+Toplink) but that's only because the spec doesn't define exacltly how to handle this. However, that being said, this seems important enough for Hibernate to be able to manage?

Reporter: Andries Schutte
When mapping multiple collections to the root node, an exception results (mapping and exception stack trace is shown below). This works fine if only one collection is mapped to the root node, or if one explicitly specifies unique names for each collection parent node. We are unfortunately restricted by having to use customer-defined XSDs, so this is a show-stopper for us.
