Error creating bean with name entityManagerFactory

Question

I am trying to run a dbtest but I get the following error        Caused by  org springframework beans factory BeanCreationException    Error creating bean with name  entityManagerFactory  defined in class   path resource  root-context xml   Invocation of init method failed    nested exception is java lang AbstractMethodError    org springframework orm jpa persistenceunit SpringPersistenceUnitInfo getValidationMode  Ljavax persistence ValidationMode     And because of that I also get the following error        Caused by  org springframework beans factory BeanCreationException    Error creating bean with name  personRepository  defined in class path   resource  root-context xml   Initialization of bean failed  nested   exception is org springframework beans factory BeanCreationException    Error creating bean with name  entityManagerFactory  defined in class   path resource  root-context xml   Invocation of init method failed    nested exception is java lang AbstractMethodError    org springframework orm jpa persistenceunit SpringPersistenceUnitInfo getValidationMode  Ljavax persistence ValidationMode    So we have to take alook at my root-context file and it look the following      lt  xml version  1 0  encoding  UTF-8   gt   lt beans xmlns  http   www springframework org schema beans      xmlns xsi  http   www w3 org 2001 XMLSchema-instance      xsi schemaLocation  http   www

Adding dependencies didn t fix the issue at my end   The issue was happening at my end because of  additional  fields that are part of the   Entity  class and don t exist in the database   I removed the additional fields from the  Entity class and it worked

This sounds like a ClassLoader conflict  I d bet you have the javax persistence api 1 x on the classpath somewhere  whereas Spring is trying to access ValidationMode  which was only introduced in JPA 2 0   Since you use Maven  do mvn dependency tree  find the artifact    lt dependency gt       lt groupId gt javax persistence lt  groupId gt       lt artifactId gt persistence-api lt  artifactId gt       lt version gt 1 0 lt  version gt   lt  dependency gt    And remove it from your setup   See Excluding Dependencies   AFAIK there is no such general distribution for JPA 2  but you can use this Hibernate-specific version    lt dependency gt       lt groupId gt org hibernate javax persistence lt  groupId gt       lt artifactId gt hibernate-jpa-2 0-api lt  artifactId gt       lt version gt 1 0 1 Final lt  version gt   lt  dependency gt    OK  since that doesn t work  you still seem to have some JPA-1 version in there somewhere  In a test method  add this code   System out println EntityManager class getProtectionDomain                                          getCodeSource                                          getLocation       See where that points you and get rid of that artifact     Ahh  now I finally see the problem  Get rid of this    lt dependency gt       lt groupId gt org springframework lt  groupId gt       lt artifactId gt spring-jpa lt  artifactId gt       lt version gt 2 0 8 lt  version gt   lt  dependency gt    and replace it with   lt dependency gt       lt groupId gt org springframework lt  groupId gt       lt artifactId gt spring-orm lt  artifactId gt       lt version gt 3 2 5 RELEASE lt  version gt   lt  dependency gt    On a different note  you should set all test libraries  spring-test  easymock etc   to   lt scope gt test lt  scope gt
