Question

我是春天的新手，所以这可能是一个微不足道的问题。但我正在研究现有项目，并尝试在此post

之后添加拦截器

如何将拦截器连接到上下文文件？

我正在获得初始化异常：

exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in class path resource [jpaAppContext.xml]: Invocation of init method failed; nested exception is org.hibernate.HibernateException: 'hibernate.dialect' must be set when no Connection available

这就是我的上下文文件的样子：

这是试图添加拦截器的方法（没有成功......）：

<bean id="sessionFactory"
      class="org.springframework.orm.hibernate3.HibernateInterceptor">
    <property name="entityInterceptor">
        <bean class="com.foo.bar.utils.audit.MyAuditInterceptor"/>
    </property>
</bean>

这是我的拦截器：

import org.hibernate.EmptyInterceptor;
import java.io.Serializable;

public class AccountManagerAuditInterceptor extends EmptyInterceptor {
    public Boolean onSave(Object entity,Serializable id,
                          Object[] state,String[] propertyNames,Type[] types)throws CallbackException {
        System.out.println("onSave");
        return false;
    }
    public boolean onFlushDirty(Object entity,Serializable id,
                                Object[] currentState,Object[] previousState,
                                String[] propertyNames,Type[] types)
            throws CallbackException {
        System.out.println("onFlushDirty");
        return false;
    }
    public void onDelete(Object entity, Serializable id,
                         Object[] state, String[] propertyNames,
                         Type[] types) {
        System.out.println("onDelete");

    }
    public void preFlush(Iterator iterator) {
        System.out.println("preFlush");
    }

    public void postFlush(Iterator iterator) {
        System.out.println("postFlush");
    }

}

该错误与拦截器无关。取消注释在entityFactoryBean中设置persistentUnitName属性的行，并验证persistence.xml是否与所需属性一起存在。这是一个例子 - https://paste.ee/p/j8hkI

将审计拦截器连接到弹簧上下文
