the intercept component don't work!

[chlol]

my test intercept:
@Name("interceptsTest")
@Interceptor
public class InterceptsTest {
@Logger
Log log;


@AroundInvoke
public Object doLogs(InvocationContext inv) throws Exception {
int methodModify = inv.getMethod().getModifiers();
String methodName = inv.getMethod().getName();

if (methodModify == Modifier.PUBLIC
&& (methodName.startsWith("create")
|| methodName.startsWith("update")
|| methodName.startsWith("persist")
|| methodName.startsWith("remove"))) {

Map data = inv.getContextData();
Object target = inv.getTarget();
log.debug("ContextData:" + data);
log.debug("Target:" + target);
}

return inv.proceed();
}

}


my invoke intercept class:

@Name("useIntercept")
@Interceptors(InterceptsTest.class)
public class UseIntercept {

public void persist() {
System.out.println("&&&&&&&&&&&& do persist() &&&&&&&&&&&&");
}

}

but when the persist() is executed,the intercept don't be invoked

can you help me?

help me,please
thank you

What's the code that calls persist()?

[chlol]

thank your reply!
i use a test case to call the persist method,the following is code:

@Test
 public void testIntercept() throws Exception {
 new ComponentTest() {
 protected void testComponents() throws Exception {
 invokeMethod("#{useIntercept.persist}");
 }
 }.run();
 }

[matt.drees]

I think because your component is a javabean component, you can't use @Interceptors directly on it. Instead, you do something like:

@Name("useIntercept")
@LogCrudOperations
public class UseIntercept {

 public void persist() {
 System.out.println("&&&&&&&&&&&& do persist() &&&&&&&&&&&&");
 }

}

@Interceptors(InterceptsTests.class)
@Retention(RetentionPolicy.RUNTIME)
@Target(ElementType.TYPE)
public @interface LogCrudOperations {
}

[matt.drees]

Also, your interceptor (InterceptsTest) doesn't get to be a Seam component. So @Logger won't work.

[chlol]

that's ok,thank you!

but how to define a seam component? Is not it to use @Name to define?

pardon my prolixity!

[matt.drees]

Yes, you use @Name to define a seam component. So, if you called Component.getInstance("interceptsTest"), the @Logger field would be filled.

But when Seam instantiates an interceptor from the class you specify, it just treats it like a normal object. It doesn't inject @Loggers or give it interceptors for bijection, etc.

[chlol]

i understand
thank you very much again!
