Error al crear el bean con el nombre ''org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping#0'' definido en el recurso ServletContext (1)

Esta es una limitación en Spring AOP. Cuando utiliza los puntos de AspectJ para decorar aspectos en beans, Spring usará CGLIB para generar una subclase del objetivo e invocar los aspectos de esa subclase.

Sin embargo, si la clase de destino no tiene un constructor público predeterminado, esto fallará. CGLIB tiene la capacidad de manejar esto, pero todo esto está oculto detrás del material Spring AOP y no puedes cambiar ese comportamiento.

Solo puedo sugerirle que vuelva a usar la inyección de setter para su controlador, en lugar de la inyección de constructor. No es ideal, lo sé, pero no puedo pensar en ninguna otra solución.

PROBLEMA:

Estoy creando un punto de corte para la ejecución de un método en una clase. Esta clase es una clase de controlador y se indica mediante la anotación @Controller y, por lo tanto, no se necesita ningún bean para el mismo que requiere el aspecto. Estoy adjuntando el código del servlet de dispathcher, el aspecto y la clase del controlador. ¿Puede alguien identificar cuál es el problema?
