[Hibernate-JIRA] Created: (ANN-538) Give @IndexColumn a default name

by Sven Meier (JIRA)

Give @IndexColumn a default name -------------------------------- Key: ANN-538 URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-538 Project: Hibernate Annotations Type: Improvement Versions: 3.2.1 Reporter: Sven Meier Priority: Minor It would be great, if the @IndexColumn annotation had a default 'name'. This would support users (e.g. me ;) in their effort to keep persistence annotations clear of database specifics. Additionally @IndexColumn is a rather often used annotation and it's tedious to repeat the same information (i.e. the 'name') over and over again. I'd propose 'hibernate_index', similar to the defaults in net.sf.hibernate.id.TableGenerator. Preferably this default would come from NamingStrategy, but I'm not sure how stable this interface is supposed to be. -- 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: (HHH-2122) optimization patch based on pmd rules

by Xavier Le Vourch (JIRA)

optimization patch based on pmd rules ------------------------------------- Key: HHH-2122 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2122 Project: Hibernate3 Type: Patch Environment: latest svn source Reporter: Xavier Le Vourch Priority: Minor Attachments: Optimizations.patch I've run pmd with a custom ruleset and made a few optimization changes: Double.valueOf(x).doubleValue() -> Double.parseDouble(x) append("x") -> append('x') x != null && x instanceof X -> x instanceof X list.toArray uses correctly sized array as argument new String(str) -> str if (expr == false) -> if (!expr) append(s1 + s2) -> append(s1).append(s2) loop over array to add to list -> list.addAll(Arrays.asList(<array>)) extra ; removed name.toLowerCase().equals("rowid") -> name.equalsIgnoreCase("rowid") use of System.arraycopy instead of loop I could break the patch in several parts if that makes it easier to analyze.

[Hibernate-JIRA] Created: (ANN-480) Query by Example in annotation form

by M N G (JIRA)

Query by Example in annotation form ----------------------------------- Key: ANN-480 URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-480 Project: Hibernate Annotations Type: New Feature Environment: jdk >= 1.5, hibernate >= 3, ant > 1.5 Reporter: M N G Priority: Minor Attachments: searchable.tar.gz Interested in adsorbing this framework I built? Takes all the work out of creating a Criteria. Similar to how Query by Example, this small framework I wrote builds Criteria from annotated pojos. A pojo is annotated to map hibernate bean mappings to methods. The annotated pojo's class is registered in the Registry, which uses reflecting to define the signatures to create the Criteria for the pojo. The values to search for are set in the pojo and the pojo is passed to the Builder. The Builder uses the registry to create the Criteria delimited by the values in the annotated pojo. Not entirely mature yet (does not support all Criteria Restrictions) and the handling of sorting results is a bit unwieldy. It works tho. Attached is a copy of the framework. It includes a unit test that kick starts a HSQL database to demostrate the framework. -- 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: (ANN-526) Property xyz has an unbound type - is that so?

by Sebastian Kirsch (JIRA)

Property xyz has an unbound type - is that so? ---------------------------------------------- Key: ANN-526 URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-526 Project: Hibernate Annotations Type: Bug Versions: 3.2.1 Reporter: Sebastian Kirsch Priority: Minor Attachments: Hibernate ANN-526.zip I get this "Property reference has an unbound type and no explictit target entity" exception and I think this is not exactly true. I'm not sure if this is a bug or a feature requests though. Have a look at the attached files and read on. I guess the model ist pretty easy to understand. The AbstractGeneric allows my to have concrete entities referring to specifc other subclasses - as seen in ConcreteOther and ConcreteSelf. The test case "workingClasses" shows us that Hibernate may work with this model - note that the class AbstractGeneric itslef was NOT added to the configuration. Now for the problem: The class OtherEntity is a completly different entity, but it refers to instances of AbstractGeneric - to any subclass of it actually, as AbstractGeneric is obviously abstract. If you run the test case "otherClass" the first part states that Hibernate doesn't know AbstractGeneric - which is fine, so I add that class to the configuration and try to build a session factory again. Now we receive the beforementioned exception. That's the situation. So is AbstractGeneric really an unbound type? I'd say it is not - T has an upper bound which should be good enough to work with - we know the table and the PK... -- 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: (ANN-539) Generics and @Embedded doesn't work

by Christophe Vanfleteren (JIRA)

Generics and @Embedded doesn't work ----------------------------------- Key: ANN-539 URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-539 Project: Hibernate Annotations Type: Bug Versions: 3.2.1 Environment: Hibernate 3.2.1, Oracle 10XE Reporter: Christophe Vanfleteren Attachments: generic.zip It doesn't seem to be possible to use a plain generic field as a component, for example: @Embedded private Range<Integer> bounds doesn't work (you get an "org.hibernate.AnnotationException: Property generic.GenericRange.min has an unbound type and no explicit target entity. Resolve this Generic usage issue or set an explicit target attribute (eg @OneToMany(target=) or use an explicit @Type") error. It does work when you extend the generic class in which you define the type (IntegerRange extends Range<Integer>) for example: @Embedded private IntegerRange bounds works I've attached some classes that demeonstrate this problem.

[Hibernate-JIRA] Created: (ANN-506) Request for Expression Language (EL) for Validator annotations

by Chris Hansen (JIRA)

Request for Expression Language (EL) for Validator annotations -------------------------------------------------------------- Key: ANN-506 URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-506 Project: Hibernate Annotations Type: New Feature Components: validator Environment: All Reporter: Chris Hansen Since annotations are limited to primitive types, I would like to see a type of EL for the Validator annotations (similar to the JSF/JSP EL). This would effectively overcome this limitation of annotations and allow for very powerful functionality, such as utilizing the natural ordering of classes. For example: @Range(min="#{MyClass.MIN_OBJECT}", max="#{MyClass.MAX_OBJECT}") public MyClass getCurrent() Assuming MIN_OBJECT and MAX_OBJECT are (static, final) instances of MyClass and MyClass implements Comparable<myClass>, the validator could compare the return value of the method with both MIN_OBJECT and MAX_OBJECT and validate that it is within the desired range. This is just an example. I'm sure there are many more interesting uses possible because this is a powerful concept. The regular functionality of the annotatinos could be preserved by treating static (non-EL) values, such as the string "0", as old-style primitives, e.g. @Min(value="0"). -- 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: (ANN-434) Confusing error message with @EmbeddedId and @Id

by Patrick Moore (JIRA)

Confusing error message with @EmbeddedId and @Id ------------------------------------------------ Key: ANN-434 URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-434 Project: Hibernate Annotations Type: Bug Versions: 3.2.0.cr1 Environment: Hibernate 3.2.0.cr2 Reporter: Patrick Moore trying to create an entity with embeddedid and automatically generated ids. The resulting error message was very confusing and may be a bug as well. (See below for sample files) Notice the message is that TransPolId doesn't have an @Id property when in fact it does. The problem is 'solved' by removing the @Id in the TransPolId class. This caused a lot of wasted time on my part please fix for the next person! -------------------------------------------------------------------------------- Some additional debugging notes: The problem is caused in part because when expanding TransPolId to within AnnotationBinder.processElementAnnotations() isIdentifierMapper == false so none of the checks looking for this sort of thing execute. I believe the solution is to change AnnotationBinder.bindId() as follows: (original): if ( isComposite ) { id = fillComponent( propertyHolder, inferredData, isPropertyAnnotated, propertyAccessor, false, entityBinder, isEmbedded, isIdentifierMapper, mappings ); Component componentId = (Component) id; componentId.setKey( true ); if ( componentId.getPropertySpan() == 0 ) { throw new AnnotationException( componentId.getComponentClassName() + " has no persistent id property" ); } } (changed): if ( isComposite ) { id = fillComponent( propertyHolder, inferredData, isPropertyAnnotated, propertyAccessor, false, entityBinder, isEmbedded, true, mappings <<<<<<<<<<<<<<< isIdentifierMapper replaced by true ); Component componentId = (Component) id; componentId.setKey( true ); if ( componentId.getPropertySpan() == 0 ) { throw new AnnotationException( componentId.getComponentClassName() + " has no persistent id property" ); } } Output: java.vm.name=Java HotSpot(TM) Client VM, cache.provider_class=org.hibernate.cache.NoCacheProvider, file.encoding=Cp1252, java.specification.version=1.5, hibernate.show_sql=true, hibernate.connection.pool_size=1} 16:19:01,109 DEBUG [Configuration] Preparing to build session factory with filters : {} 16:19:01,109 DEBUG [AnnotationConfiguration] Execute first pass mapping processing 16:19:01,109 DEBUG [AnnotationConfiguration] Process hbm files 16:19:01,109 DEBUG [AnnotationConfiguration] Process annotated classes 16:19:01,125 INFO [AnnotationBinder] Binding entity from annotated class: com.transparentpolitics.core.persistence.IdUsing1 16:19:01,125 DEBUG [Ejb3Column] Binding column DTYPE unique false 16:19:01,125 DEBUG [EntityBinder] Import with entity name=IdUsing1 16:19:01,125 INFO [EntityBinder] Bind entity com.transparentpolitics.core.persistence.IdUsing1 on table IdUsing1 16:19:01,125 DEBUG [AnnotationBinder] Processing com.transparentpolitics.core.persistence.IdUsing1 property annotation 16:19:01,125 DEBUG [AnnotationBinder] Processing com.transparentpolitics.core.persistence.IdUsing1 field annotation 16:19:01,125 DEBUG [AnnotationBinder] Processing annotations of com.transparentpolitics.core.persistence.IdUsing1.transid 16:19:01,125 DEBUG [Ejb3Column] Binding column transid unique false 16:19:01,125 DEBUG [AnnotationBinder] transid is an id 16:19:01,125 DEBUG [AnnotationBinder] Binding component with path: com.transparentpolitics.core.persistence.IdUsing1.transid 16:19:01,125 DEBUG [AnnotationBinder] Processing com.transparentpolitics.core.persistence.TransPolId field annotation 16:19:01,125 DEBUG [AnnotationBinder] Processing annotations of com.transparentpolitics.core.persistence.TransPolId.id 16:19:01,125 DEBUG [Ejb3Column] Binding column id unique false 16:19:01,125 DEBUG [AnnotationBinder] id is an id 16:19:01,125 DEBUG [SimpleValueBinder] building SimpleValue for id 16:19:01,125 DEBUG [PropertyBinder] Building property id 16:19:01,125 DEBUG [PropertyBinder] Cascading id with null 16:19:01,125 DEBUG [AnnotationBinder] Bind @Id on id org.hibernate.AnnotationException: com.transparentpolitics.core.persistence.TransPolId has no persistent id property at org.hibernate.cfg.AnnotationBinder.bindId(AnnotationBinder.java:1686) at org.hibernate.cfg.AnnotationBinder.processElementAnnotations(AnnotationBinder.java:1170) at org.hibernate.cfg.AnnotationBinder.bindClass(AnnotationBinder.java:699) at org.hibernate.cfg.AnnotationConfiguration.processArtifactsOfType(AnnotationConfiguration.java:353) at org.hibernate.cfg.AnnotationConfiguration.secondPassCompile(AnnotationConfiguration.java:265) at org.hibernate.cfg.Configuration.generateDropSchemaScript(Configuration.java:682) ... 20 more @Embeddable public class TransPolId implements Serializable { @Id @GeneratedValue public Long id; @Override public boolean equals(Object o) { if ( o instanceof TransPolId ) { return ((TransPolId)o).id.equals(id); } return false; } @Override public int hashCode() { return id.hashCode(); } } @Entity public class IdUsing1 { @EmbeddedId public TransPolId id; public String value; } -- 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
