Runtime exception thrown by GatewayProxyFactoryBean

Question

Migrating to Spring Integration 4.0.4, the following exception is thrown when using a service bean created with GatewayProxyFactoryBean:

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

Our design uses GatewayProxyFactoryBean extensively and this exception seems to be new. In this case we are not using any SpEL expressions. How can this exception be avoided?

Answer 1

Actually it isn't Exception, but just WARN.

From one side you can just ignore it or decrease logging level for the org.springframework.integration.expression.ExpressionUtils category.

Or, of course, and what will be better and even recommended, when you create your own GatewayProxyFactoryBean, provide for it BeanFactory and invoke afterPropertiesSet() of that GatewayProxyFactoryBean.
