Question

我将MDB配置为接收传入消息，并使用JPA（eclipseLink）通过SLSB保留它。数据库插入一次性消息但在负载条件下（每秒3或4条消息），数据不会保留在DB中。我可以看到sql在日志中插入查询但在DB中没有数据。持久性文件：

切换到MDB的EJB2样式配置基本原因： EJB3样式的MDB方法由CDI注入包装。堆栈跟踪中的一个包装类是：com.oracle.pitchfork.intercept.MethodInvocationInvocationContext 这是在weblogic中的spring框架模块jar中 MethodInvocationInvocationContext在“java：comp / WebServiceContext”的JNDI树中查找WebServiceContext 拥有jax-ws服务会将WebServiceContext放在“java：comp / WebServiceContext”中如果存在WebServiceContext，则MethodInvocationInvocationContext尝试访问MessageDrivenContext的值规范要求WebServiceContext在Web服务调用之外访问时抛出IllegalStateException

MDB不在SQL Server中持久保存数据
