效果

下图分别为演示方法和该方法执行完成后控制台打印的日志结果

Log Object

@Data
public class LogBO {

    /**
     * 请求URI
     */
    private String requestURI;
    /**
     * 方法名
     */
    private String method;

    /**
     * 方法的输入
     */
    private Object input;

    /**
     * 方法的输出
     */
    private Object output;

    /**
     * 方法耗时 (ms)
     */
    private Long timeConsuming;

    /**
     * 方法调用的时间
     */
    private Date date;


    public LogBO() {
        this.date = new Date();
        if (Objects.nonNull(RequestContext.getRequest())) {
            this.requestURI = RequestContext.getRequest().getRequestURI();
        }
    }
}

Annotation

@Target({ElementType.METHOD})
@Retention(RetentionPolicy.RUNTIME)
@Documented
public @interface Log {

}

Aspect

@Slf4j
@Aspect
@Component
public class LogAspect {

    @Pointcut("@annotation(com.xxx.demo.log.Log)")
    public void logPointCut() {
        //definition
    }

    @Around(value = "logPointCut()")
    public void logAround(ProceedingJoinPoint joinPoint) throws Throwable {
        LogBO logBO = new LogBO();
        // get current method
        Method method = ((MethodSignature) joinPoint.getSignature()).getMethod();
        logBO.setMethod(method.getDeclaringClass().getName() + "." + method.getName());
        Map<String, Object> input = this.getInput(joinPoint, method);
        logBO.setInput(input);
        long startTime = System.currentTimeMillis();
        // get method return
        Object output = joinPoint.proceed();
        logBO.setOutput(output);
        logBO.setTimeConsuming(System.currentTimeMillis() - startTime);
        log.info(JSONObject.toJSONString(logBO));
    }

    private Map<String, Object> getInput(ProceedingJoinPoint joinPoint, Method method) {
        // get parameter names
        String[] parameterNames = new DefaultParameterNameDiscoverer().getParameterNames(method);
        Object[] args = joinPoint.getArgs();
        Map<String, Object> params = new HashMap<>(8);
        if (parameterNames != null && parameterNames.length != 0) {
            for (int i = 0; i < parameterNames.length; i++) {
                params.put(parameterNames[i], args[i]);
            }
        }
        return params;
    }

}

Util

public class RequestContext {

    public static HttpServletRequest getRequest() {
        ServletRequestAttributes requestAttributes = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();
        return Objects.isNull(requestAttributes) ? null : requestAttributes.getRequest();
    }

}
