Interface MethodInterceptor

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

public interface MethodInterceptor

An interceptor will be called instead of the normal method invocation for proxied beans. A typical scenario for an MethodInterceptor is transaction handling:

 public Object intercept(Object bean, Method method, Object[] args) throws Exception {
      startTransaction();
      try {
          method.invoke(bean, args);
          commitTransaction();
      } catch (Exception ex) {
          rollbackTransaction();
      } finally {
          closeTransaction();
      }
 }
 

The MethodInterceptor, as any other bean, can enjoy depdendency injection via the @Inject annotation.
