迁移到Spring Integration 4.0.4 时，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

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？

    实际上它不是Exception，而只是 WARN .

    从一侧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，当你创建自己的 GatewayProxyFactoryBean 时，会更好甚至推荐什么，提供 BeanFactory 并调用 GatewayProxyFactoryBean 的 afterPropertiesSet() .

    这有点晚了，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>
