Nothing done with the interceptor

[marcpirat]

hi


i try to use spring interceptor

applicationContext.xml

<bean id="userAdminDao" class="com.server.admin.UserAdminImpl">
  <property name="userDao" ref="adminJdbcDao"/>
</bean> 

<bean id="securityInterceptor" class="com.server.admin.SecurityInterceptor"></bean>
    
<bean id="interceptedService" class="org.springframework.aop.framework.ProxyFactoryBean">
  <property name="target">
    <ref bean="userAdminDao"/>
  </property>
  <property name="interceptorNames">
    <list>
      <value>securityInterceptor</value>
    </list>
  </property>
</bean>

interceptor code

public class SecurityInterceptor implements MethodInterceptor {

    public Object invoke(MethodInvocation methodInvocation) throws Throwable {
        long startTime = System.currentTimeMillis();

        Object result = methodInvocation.proceed();

        long duration = System.currentTimeMillis() - startTime;
        Method method = methodInvocation.getMethod();

        String methodName = method.getDeclaringClass().getName() + "." + method.getName();
        System.out.println("Method '" + methodName + "' took " + duration + " milliseconds to run");

        return null;
    }
}

my test class

public class MonServiceTest extends TestCase {

    public void testMonService() {

        ApplicationContext context = new ClassPathXmlApplicationContext(new String[]{"applicationContext.xml"});
        UserAdminImpl userAdmin = (UserAdminImpl) context.getBean("userAdminDao");
        userAdmin.getUser("4");

    }
}

i don't see the output of the SecurityInterceptor,so it's not executed..

any idea?

Use the search, this question has been answered numerous times.

You aren't using the proxied instance. Your 'userAdminDao' isn't proxied your 'interceptedService' is. Use the latter. To prevent access to your unproxied instance define it as an anonymous inner bean.

Next to that read chapter 6 of the reference guide that explains spring AOP.

You are casting to the implementation cast to the interface (UserAdmin). Again that question has been answered numerous times too .
