Caused by: org.hibernate.MappingException: The increment size of the [MY_SEQ] sequence is set to [50] in the entity mapping while the associated database sequence increment size is [1].

While upgrading from hibernate 3 to hibernate 5, this was one of the issues. Here is how id fields were defined in hibernate 3. @[email protected](strategy=GenerationType.AUTO, generator=”my_seq_gen”)@SequenceGenerator(name=”my_seq_gen”, sequenceName=”MY_SEQ”)private long id; So now, I added allocationSize = 1 to resolve the issue @[email protected](strategy=GenerationType.AUTO, generator=”my_seq_gen”)@SequenceGenerator(name=”my_seq_gen”, sequenceName=”MY_SEQ”, allocationSize = 1)private long id; And for new Ids I used the … Read more

Cannot create JDBC driver of class ‘com.mysql.jdbc.Driver’ for connect URL ‘jdbc:postgresql://localhost:5432/my_test’

This turned out to be a mistake in the config.  I was using mysql driver. It was a copy-paste mistake. <bean id=”dataSource” class=”org.apache.commons.dbcp2.BasicDataSource”destroy-method=”close”><property name=”driverClassName”><value>com.mysql.jdbc.Driver</value></property>   Here is the correct config: <bean id=”dataSource” class=”org.apache.commons.dbcp2.BasicDataSource”destroy-method=”close”><property name=”driverClassName”> <value>org.postgresql.Driver</value></property>   And the postgres entry in pom.xml : <dependency><groupId>org.postgresql</groupId><artifactId>postgresql</artifactId><version>42.2.23</version></dependency>

Exception encountered during context initialization – cancelling refresh attempt: org.springframework.beans.factory.BeanCreationException: Error creating bean with name ‘sessionFactory’ defined in class path resource [xml]: Invocation of init method failed; nested exception is java.lang.NoClassDefFoundError: javax/validation/ValidatorFactory

The above error is quite obvious that javax.validation is missing. To fix this issue, we would need to import hibernate validator. Here is the dependency to be added to the pom. <dependency><groupId>org.hibernate</groupId><artifactId>hibernate-validator</artifactId><version>6.2.1.Final</version></dependency> Make sure that the version defined above is compatible with hibernate core.

[main] WARN GenericApplicationContext:591 – Exception encountered during context initialization – cancelling refresh attempt: org.springframework.beans.factory.BeanCreationException: Error creating bean with name ‘sessionFactory’ defined in class path resource : Invocation of init method failed; nested exception is java.lang.NoClassDefFoundError: net/bytebuddy/TypeCache

On upgrading Hibernate from version 3 to version 5, I got the above error. Turned out that we were also using Mockito and it also has a dependency on byte buddy. So there was conflict of versions of byet buddy. So here is fix: <dependency><groupId>org.mockito</groupId><artifactId>mockito-core</artifactId><version>2.2.28</version><scope>test</scope><exclusions><exclusion><groupId>net.bytebuddy</groupId><artifactId>byte-buddy</artifactId></exclusion></exclusions></dependency> exclude the byte-buddy jar from mockito.
