[Hibernate-JIRA] Created: (ANN-599) @MapKey throws an exception if the key is part of a non-embedded composite ID

by Chris Rose (JIRA)

@MapKey throws an exception if the key is part of a non-embedded composite ID ----------------------------------------------------------------------------- Key: ANN-599 URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-599 Project: Hibernate Annotations Issue Type: Bug Components: binder Affects Versions: 3.3.0.ga Environment: Hibernate Core 3.2.3, Annotations 3.3.0.GA, Oracle 9i, Java5 Reporter: Chris Rose Priority: Minor Like mentioned in ANN-43, the property binder for MapKey does not completely handle identifier properties in the owned entity. Unlike that issue, which is clearly fixed, this issue comes when the mapped entity has a composite primary key that is _not_ handled with a separate PK class. For example: class Owner { @Id Long getOwnerId () {} @OneToMany(mappedBy="owner") @MapKey(name="propertyName") Map<String,Value> getProperties (){} } class Value { @Id String getPropertyName () {} @Id Long getOwnerId (){} @ManyToOne @JoinColumn(name="owner_id") Owner getOwner () } This generates an exception when I initialize the session: 11:36:27,800 INFO CollectionBinder:627 - Mapping collection: Owner.properties -> properties Exception in thread "main" org.hibernate.AnnotationException: Map key property not found: Value.propertyName at org.hibernate.cfg.annotations.MapBinder.bindKeyFromAssociationTable(MapBinder.java:103) at org.hibernate.cfg.annotations.MapBinder.access$000(MapBinder.java:53) at org.hibernate.cfg.annotations.MapBinder$1.secondPass(MapBinder.java:83) at org.hibernate.cfg.CollectionSecondPass.doSecondPass(CollectionSecondPass.java:43) at org.hibernate.cfg.Configuration.secondPassCompile(Configuration.java:1130) at org.hibernate.cfg.AnnotationConfiguration.secondPassCompile(AnnotationConfiguration.java:316) at org.hibernate.cfg.Configuration.buildSessionFactory(Configuration.java:1286) at org.hibernate.cfg.AnnotationConfiguration.buildSessionFactory(AnnotationConfiguration.java:915) at com.planet.core.SessionFactoryTest.main(SessionFactoryTest.java:46) >From the code, it's clear that the BinderHelper.findPropertyByName () method only acquires the _first_ identifier property on the Value class, which appears to be the alphabetically first one, rather than the multiple ones. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira

[Hibernate-JIRA] Commented: (HHH-1936) IdentityGenerator doesn't support BigInteger as a valid identity type.

by Andrew Thompson (JIRA)

[ http://opensource.atlassian.com/projects/hibernate/browse/HHH-1936?page=c... ] Andrew Thompson commented on HHH-1936: -------------------------------------- To break the original issue down a bit for clarity: * Sybase *requires* that all auto-increment identity columns be of type numeric: e.g. create table Foo ( foo_id numeric(9,0) identity ) * Sybase's JConnect drvier maps this to BigInteger (well BigDecimal really) in Java code [*] see below * Hibernate won't allow BigInteger as a primary key column for an object, due, I think, to code in IdentityGeneratorFactory which checks explicitly Result - we're caught between the proverbial rock and hard place. So to partially get around this, we do this: <id name="fooNum" column="foo_id" type="com.example.hibernate.usertype.NumericType"> <generator class="identity" /> </id> And NumericType is then a bit ghastly.... public class NumericType extends LongType { public void set(PreparedStatement st, Object value, int index) throws HibernateException, SQLException { st.setBigDecimal( index, new BigDecimal( BigInteger.valueOf(((Long)value).longValue()))); } public int sqlType() { return Types.NUMERIC; } } Basically the field in our class is then a Long and we fake out the mapping from Long to Numeric here. There's a side issue where every time we want to use HQL or criteria queries, we have to be very careful to always remember to call Query.setBigDecimal() and convert the Long to an BigInteger manually. If we don't do that (i.e. we call setLong or let Hibernate figure it out) then the Sybase JConnect driver emits SQL code which causes the database to ignore the index (because the types don't match) and we table scan the table. What we want to do is to change our class to use BigInteger as the id column, because that's really what is needed with Sybase, but the checks in Hibernate won't allow that. > IdentityGenerator doesn't support BigInteger as a valid identity type. > ---------------------------------------------------------------------- > > Key: HHH-1936 > URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-1936 > Project: Hibernate3 > Issue Type: Bug > Components: core > Affects Versions: 3.0.5 > Environment: Hibernate 3.0.5, Sybase 12.05, Window/ Unix > Reporter: Leonid Shtivelman > > Identity generator strategy doesn't support BigInteger as a valid id type. This causes problem with Sybase which requires identity column to be numeric. It would seem an obvious way to get around this problem is to set column mapping to long in hibernate xml and the actual java object. This will solve obvious problem of creating identity, but will cause performance problem on selection. In order for Sybase to use index for parameter query the variable type of the parameter and column index type has to be the same. If ones maps column type to Long, Hibernate will use JDBC method setLong(long) to set value in the prepared statement. This will cause mismatch between parameter type and column index type, and Sybase will not use index to locate index. As you can see this is a big problem for anyone that is using identity columns Sybase and Hibernate -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira

[Hibernate-JIRA] Created: (HBX-932) reveng creates field names which are Java reserved words

by Gary Plante (JIRA)

reveng creates field names which are Java reserved words -------------------------------------------------------- Key: HBX-932 URL: http://opensource.atlassian.com/projects/hibernate/browse/HBX-932 Project: Hibernate Tools Issue Type: Bug Components: reverse-engineer Affects Versions: 3.2beta9 Environment: Hibernate 3.2; MS-SQL 2000; Eclipse 3.2.1 Reporter: Gary Plante Priority: Minor I am using the reverse engineering tool to create POJO's from an existing database (schema). Unfortunately, one of the tables names happens to be the same as a Java reserved word (i.e. Switch). The tool creates the .java code and uses the lower case 'switch' as the name of field (if the the table is referenced by another table). This causes the Java code not to compile! E.g: [code] // Generated 2007/04/18 09:53:07 by Hibernate Tools 3.2.0.b9 /** * ActiveEndpoint generated by hbm2java */ public class ActiveEndpoint implements java.io.Serializable { private int serviceId; private Switch switch; public ActiveEndpoint() { } public ActiveEndpoint(int serviceId, Switch switch) { this.serviceId = serviceId; this.switch = switch; } ... // Generated 2007/04/18 09:53:07 by Hibernate Tools 3.2.0.b9 /** * Switch generated by hbm2java */ public class Switch implements java.io.Serializable { private int id; private String name; ... [/code] Explicitly forcing the name to something else in hibernate.reveng.xml (e.g. Switch -> CTISwitch) does not help - the field name remains the same even if the class name changes. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira
