Example

The following is a sample interceptor and configuration file, where one interceptor class implements all four interfaces.

Configuration file CMServiceConfig.xml:

<ServiceInterceptors
    <Service name="CMLTBTCP">
        <Interceptor action="add">
            com.splwg.cis.interceptortest.InterceptorTest
        </Interceptor> 
        <Interceptor action="change">
            com.splwg.cis.interceptortest.InterceptorTest
        </Interceptor> 
        <Interceptor action="delete">
            com.splwg.cis.interceptortest.InterceptorTest
        </Interceptor> 
        <Interceptor action="read">
            com.splwg.cis.interceptortest.InterceptorTest
        </Interceptor>
    </Service>
</ServiceInterceptors>

Class com.splwg.cm.interceptortest.InterceptorTest:
