Java 8 weblogic.management.DeploymentException:java.lang.NoSuchMethodError:javax.persistence.spi.PersistenceUnitInfo.getValidationMode（）

在Weblogic:12.2.1上部署EJB应用程序时，我面临一个例外：

“weblogic.management.DeploymentException:java.lang.NoSuchMethodError:javax.persistence.spi.PersistenceUnitInfo.getValidationMode（）Ljavax/persistence/ValidationMode”

我在persistence.xml中有以下配置来指定持久性提供程序

<persistence-unit name="entityManager">
<!-- Use Hibernate persistency -->  
<provider>org.hibernate.ejb.HibernatePersistence</provider>

org.hibernate.ejb.HibernatePersistence

在weblogic-application.xml中

<prefer-application-packages>
<package-name>antlr.*</package-name>
<package-name>javax.persistence.*</package-name>

antlr*
javax.persistence*

在此异常之前，我遇到了一个异常“实例化持久性提供程序类java.lang.ClassNotFoundException:org.hibernate.ejb.HibernatePersistence时出错”，该异常是从

从那时起，我就面临着这个例外

我在WL_域/lib中提供了以下JAR：-

hibernate-jpa-2.0-api-1.0.1.Final

com.oracle.jpa2support_1.0.0.0_2-1

冬眠

dom4j

在WL_域中的以下文件的类路径中也提供了 ---setDomainEnv.cmd

设置EXT\u PRE\u CLASSPATH=C:\Projects\GMPP-CBOSS\MFSS\MFSS\lib\hibernate\slf4j- api.jar；C:\Projects\GMPP-CBOSS\MFSS\MFSS\lib\hibernate\hibernate-jpa-api.jar

---TrivEnv.cmd

设置CLASSPATH=C:\oracle\Middleware2\modules\javax.persistence\u 1.0.0\u 1-0- 2.jar；C:\oracle\Middleware2\modules\com.oracle.jpa2support\u 1.0.0.0\u 2- 1.罐子；%类路径%

----commonEnv.cmd------oracle_common/common/bin

设置CLASSPATH=C:\oracle\Middleware2\modules\javax.persistence\u 1.0.0\u 1-0- 2.jar；C:\oracle\Middleware2\modules\com.oracle.jpa2support_1.0.0.0_2-1.jar

有可能javax.persistence_1.0.0.0_2-0-0.jar被添加到服务器类路径的开头和结尾（在DOMAIN_HOME/lib dir中）

因此，同一服务器类路径中同一jar的两个版本会导致不一致

解决方案 从域\u HOME/lib目录中删除javax.persistence\u 1.0.0\u 2-0-0.jar
