为什么Spring4.1.3 webmvc在weblogic12c中内部调用hibernate-validator

Question

I am deploying a application in weblogic12c.It is spring4.1.3 build rest service. Earlier all jars were inside war file and I set

<prefer-web-inf-classes>true</prefer-web-inf-classes>

Now we removed the supporting jars from war file and deploying the application in weblogic 12c. But now it's throwing below exception. I don't understand how SpringMVC calls the hibernate validator. I see hibernate.validator_4_0_1.jar is available in the wlserver/modules folder of weblogic.

 org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.validation.beanvalidation.OptionalValidatorFactoryBean#0': Invocation of init method failed; nested exception is java.lang.AbstractMethodError: org.hibernate.validator.engine.ConfigurationImpl.getDefaultParameterNameProvider()Ljavax/validation/ParameterNameProvider;

Answer 1

I fixed this. I got that weblogic has a weblogic.server.merged.jar which is inside weblogic/12c/wlserver/modules/features and It has javax.validation and hibernate.validator packages and causing the mess. I just updated these packages here manually by latest validation-api.jar and hibernate-validator-5.2.2.jar. It worked. Weblogic does not really cares jars under wlserver/modules but It has combined all these jars to weblogic.server.merged.jar and I needed to update the packages of the same.
