I am learning Interceptor Binding using annotations. The version is Java 11, and Jakarta EJB 4. The server is GlassFish 7. There is no deployment descriptor and annotations archive all requirements.

I have added a print statement to see whether it’s working. But, there is no output in the server log. Here is the code.

Auth.java

package com.aadhil.ejb.annotation;

import java.lang.annotation.*;

import jakarta.interceptor.InterceptorBinding;

@InterceptorBinding
@Retention(RetentionPolicy.RUNTIME)
@Target({ElementType.TYPE, ElementType.METHOD, ElementType.CONSTRUCTOR})
public @interface Auth {
}

AuthInterceptor.java

package com.aadhil.ejb.interceptor;

import com.aadhil.ejb.annotation.Auth;
import jakarta.interceptor.AroundInvoke;
import jakarta.interceptor.Interceptor;
import jakarta.interceptor.InvocationContext;

@Auth
@Interceptor
public class AuthInterceptor {
    @AroundInvoke
    public Object authenticate(InvocationContext invocationContext) throws Exception {
        System.out.println("Auth Interceptor");
        return invocationContext.proceed();
    }
}

LoginImpl.java

package com.aadhil.ejb.impl;

import com.aadhil.ejb.annotation.Auth;
import com.aadhil.ejb.entity.User;
import com.aadhil.ejb.remote.Login;
import jakarta.ejb.Stateless;
import jakarta.persistence.EntityManager;
import jakarta.persistence.NoResultException;
import jakarta.persistence.PersistenceContext;

@Auth
@Stateless
public class LoginImpl implements Login {
    @PersistenceContext(unitName = "WebPU")
    private EntityManager em;

    @Override
    public User login(String email, String password) {
        try {
            return em.createQuery("SELECT u FROM User u WHERE u.username=:username AND u.password=:password", User.class)
                    .setParameter("username", email)
                    .setParameter("password", password)
                    .getSingleResult();
        } catch (NoResultException ex) {
            return null;
        }
    }
}

When using @Interceptors annotation in the session bean class and @AroundInvoke annotation in the interceptor class, it worked fine. But, when trying with a custom annotation class with @InterceptorBinding annotation, I cannot see any log. I also added the @Inherited annotation to my custom annotation. But I got the same result. My tutor does not use the @Inherited annotation or any XML file to configure the interceptors.
