bind Spring HandlerInterceptor only to one controller
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>
