@Antes da anotação spring não pode ser usada

  • 772
package felim.belajar_aop_spring.service;

import org.springframework.stereotype.Component;

@Component
public class HelloService {

    public String hello(String name){
        return "hello " + name;
    }


    public String bye(String name){
        return "bye " + name;
    }
}

package felim.belajar_aop_spring.aspect;

import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Before;
import org.aspectj.lang.annotation.Pointcut;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Component;

@Aspect
@Component
public class LogAspect {

    private static final Logger log = LoggerFactory.getLogger(LogAspect.class);

    @Pointcut("target(felim.belajar_aop_spring.service.HelloService)")
    public void helloLog() {
    }

    @Before("helloLog()")
    public void beforeHelloService() {
        log.info("yo");
    }
}

Estou aprendendo Spring AOP e tentando criar um aspecto de registro que registre mensagens de registro sempre que um método na HelloServiceclasse for chamado. Eu defini uma segmentação de pointcut HelloServicee usei @Beforepara criar um método de aconselhamento. No entanto, o aconselhamento não é executado e não tenho certeza se @Beforeé a anotação correta a ser usada. Meu objetivo é registrar uma mensagem antes que qualquer método HelloServiceseja invocado. Alguém poderia me ajudar a identificar o que está errado com minha implementação e sugerir como consertar? Quaisquer insights ou práticas recomendadas para registro com Spring AOP seriam muito apreciados.

    Se seguirmos a documentação do Spring para declarar um Pointcut , um @Pointcutwith executiondeve ser usado.

    Portanto, por favor, tente

    @Pointcut("execution(* HelloService.*(..))")

    para acionar isso em todos os métodos em HelloService.

    Eu testei isso com uma classe de teste como esta

    @SpringBootTest
class HelloServiceTest {

    @Autowired
    private HelloService helloService;

    @Test
    void testHelloService() {
        helloService.hello("user1");
    }
}
