I need to configure @TypeDefs for use custom @Type on package level. When I configured it following manner I am getting ClassNotFoundException. But when I put @TypeDefs on the class level it is working fine.

I have found similar kind of stackoverflow post but I haven't any idea to how to configure <resource package="com.foo.bar.thepackage"/> entry with my application-context.xml file.

According some post (as bellow), noted this a Spring related bug 

I believe this is due to a bug in Spring, where it doesn't scan the annotations in package-info, but only those on classes annotated with @Entity, @Embeddable, or @MappedSuperclass. See https://jira.springsource.org/browse/SPR-8589.

Can any one help me to resolve this issue. Thanks.

@TypeDefs declaration with package-info.java

@TypeDefs ({ @TypeDef( name="encryptedString", typeClass=EncryptedStringType.class, parameters={ @Parameter(name="encryptorRegisteredName", value="abcHibernateStringEncryptor") } ) }) package com.abc.core.model; import org.hibernate.annotations.TypeDef; import org.hibernate.annotations.TypeDefs; import org.hibernate.annotations.Parameter; import org.jasypt.hibernate4.type.EncryptedStringType;

application-context.xml

Entity class with custom @Type mapping 

package com.stee.rcm.core.model; @Entity @Table(name = "trail") public class Trail implements Serializable { @Id @GeneratedValue @Column(name = "ID") private Integer id; @Type(type="encryptedString") @Column(name = "DESCRIPTION") private String description; }

Exception

Caused by: java.lang.ClassNotFoundException : encryptedString

I too faced same issue, It seems spring have some issue to scan TypeDef when they are at package-info.java class.

Declaring resource in the configuration is nothing but packagesToScan.You have already used in your configuration and even this does not help in scanning TypeDefs.

<resource package="com.foo.bar.thepackage"/>

We can go with any of below approaches

  1. Declare TypeDef in each pojo classes(where ever userType/CustomType is used).
  2. Explicitly register CustomType to hibernate configuration.This can be done in two ways:
    1. Registering CustomType programmatic. configuration.registerTypeOverride(new EncryptedStringType(),new String[]{"encryptedString"});
    2. Declaring TypeDef in session factory bean configuration and extending local session factory bean.

Spring.xml :

<bean id="DateTypeSessionFactory" class="com.runtime.data.factory.TypeResolverSessionFactoryBean"> <property name="dataSource" ref="DateTypeDataSource"/> <property name="packagesToScan" value="com.p27.datetype"/> <property name="customTypes"> <array value-type="com.runtime.data.CustomType"> <ref bean="dateTimeCustomType"/> </array> </property> <property name="hibernateProperties"> <props> <prop key="hibernate.dialect"> ${DateType.dialect} </prop> <prop key="hibernate.show_sql"> false </prop> <prop key="hibernate.globally_quoted_identifiers"> false </prop> <prop key="hibernate.hbm2ddl.auto"> ${DateType.hbm2ddl} </prop> </props> </property> </bean> <bean id="persistentLocalDateTimeType" class="com.studio.common.data.type.WMPersistentLocalDateTime"/> <bean id="dateTimeCustomType" class="com.runtime.data.CustomType"> <property name="type" ref="persistentLocalDateTimeType"/> <property name="keys"> <list> <value>DateTime</value> <value>org.joda.time.LocalDateTime</value> </list> </property> </bean> public class CustomType { private UserType type; private String[] keys; //getters & setters }

SessionFactoryBean :

public class TypeResolverSessionFactoryBean extends LocalSessionFactoryBean { private CustomType[] customTypes; @Override protected SessionFactory buildSessionFactory(LocalSessionFactoryBuilder sfb) { if(customTypes != null) { registerCustomTypes(sfb); } return sfb.buildSessionFactory(); } protected void registerCustomTypes(LocalSessionFactoryBuilder sfb) { for (CustomType customType : customTypes) { sfb.registerTypeOverride(customType.getType(), customType.getKeys()); } } public void setCustomTypes(CustomType[] customTypes) { this.customTypes = customTypes; } }
