SpringBoot（审计） 统计接口调用次数及成功率

介绍：

　　很多时候会需要提供一些统计记录的，比如某个服务一个月的被调用量、接口的调用次数、成功调用次数等等。

优点：

　　使用AOP+Hendler对业务逻辑代码无侵入，完全解耦。通过spring boot自带的健康检查接口（/health）方便、安全。

注意：

　　数据没有被持久化，只保存在内存中，重启后数据将被重置。可按需自己实现 

代码：

　　AOP:在AOP中调用Handler

@Component
@Aspect
public class ControllerAdvice {
    private static ILogger log = LoggerFactory.getLogger(ControllerAdvice.class);

    @Around("execution(public * *..*controller.*.*(..))")
    public Object handle(ProceedingJoinPoint proceedingJoinPoint) throws Throwable {
        Object result;
        try {
            Function<ProceedingJoinPoint, AbstractControllerHandler> build = AbstractControllerHandler.getBuild();
            if (null == build) {
                AbstractControllerHandler.registerBuildFunction(DefaultControllerHandler::new);
            }
            build = AbstractControllerHandler.getBuild();
            AbstractControllerHandler controllerHandler = build.apply(proceedingJoinPoint);
            if (null == controllerHandler) {
                log.warn(String.format("The method(%s) do not be handle by controller handler.", proceedingJoinPoint.getSignature().getName()));
                result = proceedingJoinPoint.proceed();
            } else {
                result = controllerHandler.handle();
            }
        } catch (Throwable throwable) {
            RuntimeHealthIndicator.failedRequestCount++;
            log.error(new Exception(throwable), "Unknown exception- -!");

            throw throwable;
        }

        return result;
    }
}

　Handler:执行记录的逻辑

　　　　抽象类：AbstractControllerHandler 

public abstract class AbstractControllerHandler {
    private static ILogger log = LoggerFactory.getLogger(AbstractControllerHandler.class);

    private static Function<ProceedingJoinPoint, AbstractControllerHandler> build;

    public static Function<ProceedingJoinPoint, AbstractControllerHandler> getBuild() {
        return build;
    }

    public static void registerBuildFunction(Function<ProceedingJoinPoint, AbstractControllerHandler> build) {
        Assert.isNotNull(build, "build");

        AbstractControllerHandler.build = build;
    }

    protected ProceedingJoinPoint proceedingJoinPoint;
    protected HttpServletRequest httpServletRequest;
    protected String methodName;
    protected String uri;
    protected String requestBody;
    protected String ip;
    protected Method method;
    protected boolean inDataMasking;
    protected boolean outDataMasking;


    public AbstractControllerHandler(ProceedingJoinPoint proceedingJoinPoint) {
        Assert.isNotNull(proceedingJoinPoint, "proceedingJoinPoint");

        this.proceedingJoinPoint = proceedingJoinPoint;
        Signature signature = this.proceedingJoinPoint.getSignature();
        this.httpServletRequest = this.getHttpServletRequest(this.proceedingJoinPoint.getArgs());
        this.methodName = signature.getName();
        this.uri = null == this.httpServletRequest ? null : this
