GatewayProxyFactoryBean抛出的运行时异常

Question

迁移到Spring Integration 4.0.4时,使用使用以下创建的服务bean时会引发以下异常GatewayProxyFactoryBean:

Sep 30, 2014 3:45:21 PM org.springframework.integration.expression.ExpressionUtils createStandardEvaluationContext
WARNING: Creating EvaluationContext with no beanFactory

我们的设计GatewayProxyFactoryBean广泛使用,这个例外似乎是新的.在这种情况下,我们不使用任何SpEL表达式.如何避免这种异常？

Answer 1

实际上它不是Exception,而只是WARN.

从一侧您可以忽略它或降低该org.springframework.integration.expression.ExpressionUtils类别的日志记录级别.

或者,当然,什么会更好,甚至建议,当你创建你自己的GatewayProxyFactoryBean,为它BeanFactory和调用afterPropertiesSet()的那个GatewayProxyFactoryBean.
