SpringBoot（十）：aop

1、pom.xml引入aop

<dependency>
   <groupId>org.springframework.boot</groupId>
   <artifactId>spring-boot-starter-aop</artifactId>
</dependency>

2、自定义注解

@Retention(RetentionPolicy.RUNTIME)
@Target(ElementType.METHOD)
public @interface Log {
    String value() default "";
}

3、定义aspectj

@Aspect
@Component
public class LogAspectj {
    private static final Logger LOG = LoggerFactory.getLogger(LogAspectj.class);

    @Before(value = "@annotation(com.ss.quickStart.annotation.Log)")
    public void logAfterReturning(JoinPoint joinPoint){
        String className = joinPoint.getTarget().getClass().getSimpleName();
        String methodName = joinPoint.getSignature().getName();
        Object[] args = joinPoint.getArgs();
        LOG.info("方法:{}.{},参数:{}",className,methodName,JSON.toJSONString(args));
    }
}

使用@Log注解

@RequestMapping("user/batchAdd.do")
@Log
public Boolean batchAdd(UserListDTO userListDTO){
    return userService.batchAdd(userListDTO.getUserList());
}

控制台输出：

[ INFO  ] [ com.ss.quickStart.aop.LogAspectj : 33 ] - 方法:UserController.batchAdd,参数:[{"userList":[{"name":"A","sex":1},{"name":"B","sex":0}]}]
