Using Spring 3.0.2.RELEASE. I'm having 2 Controllers in package com.myCompany. The Controllers are activated via Component-scan
<context:component-scan base-package="com.myCompany" />
then I'm having a interceptor bind to the 2 controllers via
<bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping">
<property name="interceptors">
<list>
<ref bean="myInterceptor"/>
</list>
</property>
</bean>
How can i bind the interceptor to only one specific Controller or to only certain methods inside a Controller? Background: I want to inspect the URL that it contains certain parameters

To work with interceptor, you need to create @Component class that supports it and it should implement the HandlerInterceptor interface. preHandle() method − This is used to perform operations before sending the request to the controller. This method should return true to return the response to the client.
Simply put, a Spring interceptor is a class that either extends the HandlerInterceptorAdapter class or implements the HandlerInterceptor interface. The HandlerInterceptor contains three main methods: prehandle() – called before the execution of the actual handler. postHandle() – called after the handler is executed.
When you inject interceptors into a HandlerMapping bean, those interceptors apply to every handler mapped by that HandlerMapping. That was fine in the pre-annotation days, since you'd just have configure multiple HandlerMapping beans. However, with annotations, we tend to have a single DefaultAnnotationHandlerMapping that maps everything, so this model doesn't work.
The solution is to use <mvc:interceptors>, where you explicitly map paths to interceptor beans. See the docs, and this example:
<mvc:interceptors>
<mvc:interceptor>
<mvc:mapping path="/secure/*"/>
<bean class="org.example.SecurityInterceptor" />
</mvc:interceptor>
</mvc:interceptors>
