1.java.lang.AbstractMethodError:
[quote]
使用hibernate validator，在tomcat下部署没有问题，发布到weblogic(10)下面就报错了。在使用验证时有以下错误：
java.lang.AbstractMethodError: getProviderUtil
at javax.persistence.Persistence$PersistenceUtilImpl.isLoaded(Unknown Source)
出错原因是weblogic自身带有openjpa的包（hibernate、openjpa掐架？），解决方法是在spring中增加配置
dispatcher-servlet.xml
<mvc:annotation-driven validator="validator"/>
applicationContext.xml
<bean name="validator" class="org.springframework.validation.beanvalidation.LocalValidatorFactoryBean">
<property name="traversableResolver">
<bean class="com.....ExtTraversableResolver"></bean>
</property>
</bean>
其中ExtTraversableResolver代码如下：
import java.lang.annotation.ElementType;
import javax.validation.Path;
import javax.validation.TraversableResolver;
public class ExtTraversableResolver implements TraversableResolver {
public final boolean isReachable(Object traversableObject, Path.Node traversableProperty, Class<?> rootBeanType, Path pathToTraversableObject, ElementType elementType) {
return true;
}
public final boolean isCascadable(Object traversableObject, Path.Node traversableProperty, Class<?> rootBeanType, Path pathToTraversableObject, ElementType elementType) {
return true;
}
