基于Spring AOP实现注解式日志记录

AOP所需依赖

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

1.创建日志记录注解

@Target({ElementType.PARAMETER, ElementType.METHOD})
@Retention(RetentionPolicy.RUNTIME)
@Documented
public @interface Log {
    String api() default "";
}

2.创建切面写日志记录逻辑

@Aspect
@Component
public class LogAspectj {
    //织入点
    @Pointcut("@annotation(com.csf.securitydemo.annotation.Log)")
    public void logPointCut() {
    }
    //运行后执行
    @AfterReturning(pointcut = "logPointCut()",returning = "api")
    public void after(JoinPoint joinpoint,Object api){
        handleLog(joinpoint,null,api);
    }
    protected void handleLog(final JoinPoint joinPoint, final Exception e, Object api){
        try {
            // 获得注解
            MethodSignature methodSignature = (MethodSignature) joinPoint.getSignature();
            Method method = methodSignature.getMethod();
            Log annotation = null;
            if(method != null){
                annotation = method.getAnnotation(Log.class);
            }
            if (annotation == null)
            {
                return;
            }
            //注解备注参数
            System.out.println(annotation.api());
            //接口接收参数
            System.out.println(Arrays.asList(joinPoint.getArgs()));
            //接口返回参数
            System.out.println(JSON.toJSONString(api));
        } catch (Exception ex) {
            ex.printStackTrace();
        }
    }
}

3.使用：再任意接口上标注@Log注解 调用测试
