Question

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

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

我们的设计广泛使用GatewayProxyFactoryBean，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

实际上它并非Exception，而只是WARN。

从一方面，您可以忽略它或降低org.springframework.integration.expression.ExpressionUtils类别的日志记录级别。

或者，当然，当您创建自己的GatewayProxyFactoryBean时，会更好甚至推荐什么，为其BeanFactory提供afterPropertiesSet()并调用GatewayProxyFactoryBean {{1}}

有点晚了，但正如@Artem Bilan建议的那样，你可以在你的log4j.xml文件中做这样的事情，假设你正在处理一个名为console的appender

<logger name="org.springframework.integration.expression.ExpressionUtils">
    <appender-ref ref="console"/>
    <level value="ERROR"/>
</logger>
