I have defined an object, OrderServiceImpl, that performs the bulk of the work in our system. I wanted to use AOP to time the methods in it. The old tag was <bean id="orderService" class="com.xxx.OrderServiceImpl">. I wrote an implementation of MethodInterceptor that will time the invocation of the underlying method. So, I changed the configuration to match what you see below. I ran my test suite using this configuration and it worked fine and called my timerBean. However, when I deployed this same configuration to Tomcat, I get the stack trace you see at the bottom of this email. I see that it believes there is a circular dependency, but my question is - why isn't there one when I am not timing the methods. The underlying service has the exact same dependencies in both cases. Is there a simple way for me to fix this? Am I missing some very basic? Any assistance is greatly appreciated
Configuration:
<bean id="orderServiceImpl" class="com.xxx.OrderServiceImpl" >
< properties (including references to other beans) >
</bean>
<bean id="orderService" class="org.springframework.aop.framework.ProxyFactoryBean" >
<property name="target" ref="orderServiceImpl" />
<property name="interceptorNames">
<list>
<value>timeMethodBean</value>
</list>
</property>
</bean>
