Spring JPA : applicationContext.xml can not create entityManagerFactory bean - mysql

Question

I use Spring 3.2.0, JPA 2 AND my IDE is SpringToolSuit 3.1.0.
When I run Test class (main class) I get this exception, I googled but I can not find any solution.
Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in class path resource [applicationContext.xml]: Invocation of init method failed; nested exception is java.lang.reflect.UndeclaredThrowableException

Answer 1

Try adding
<property name="loadTimeWeaver">
<bean class="org.springframework.instrument.classloading.InstrumentationLoadTimeWeaver"/>
</property>
Please check here for more details about weaving for JPA

Answer 2

The correct entityManagerFactory should be :
<bean id="entityManagerFactory"
class="org.springframework.orm.jpa.LocalEntityManagerFactoryBean">
<property name="persistenceUnitName" value="testJPA"></property>
</bean>
By this factory we do not need "loadTimeWeaver".

Answer 3

Alternatively ,try adding this to your JVM start parameters
-javaagent:C:/jars/spring-instrument-3.0.4.RELEASE.jar ( or latest version)
