Question

我试图从我的春季启动应用程序中拦截第三方jar中的一个类。

我正在尝试将其作为

<context:load-time-weaver aspectj-weaving="on" weaver-class="org.springframework.instrument.classloading.ReflectiveLoadTimeWeaver"/>

    <bean id="instrumentationLoadTimeWeaver"
          class="org.springframework.instrument.classloading.InstrumentationLoadTimeWeaver"/>

虽然我的Aspect记录器类看起来像

@Aspect
public class LogInterceptor
{
    private static final Logger PERF_LOGGER = LoggerFactory.getLogger("PERFLOG");

    private static final Logger LOGGER = LoggerFactory.getLogger(LogInterceptor.class);
    private static final int SYSTEM_ERROR_STATUS_CODE = -1;
    private static final int SYSTEM_SUCCESS_STATUS_CODE = 0;



@Around(
            "execution(* com.alpha.executor.dao..*(..)) || "
                    + "execution(* com.alpha.executor.resource..*(..)) || "
                    + "execution(* com.alpha.executor.client..*(..)) || "
                    + "execution(* com.alpha.executor.service..*(..)) || "
                    + "execution(* com.alpha.executor.proxy.*.*(..)) ")
    public Object logRecordInPerflog(ProceedingJoinPoint joinPoint) throws Throwable
    {

        String activityName = joinPoint.getTarget().getClass().getSimpleName();
        String operationName = activityName + "." + joinPoint.getSignature().getName();
        RequestLog reqLog = new RequestLog(operationName, activityName, joinPoint.getArgs());

        PERF_LOGGER.info(reqLog.getLoggerString());
        try
        {
            Object result = joinPoint.proceed();
            ResponseLog resLog = new ResponseLog(reqLog, result, SYSTEM_SUCCESS_STATUS_CODE);
            PERF_LOGGER.info(resLog.getLoggerString());
            return result;
        }
        catch (Exception ex)
        {
            logException(reqLog, ex);
            throw ex;
        }
    }

    private void logException(RequestLog reqLog, Exception ex)
    {
        ResponseLog resLog;
        if (ex instanceof SvxException)
        {
            SvxException svxException = (SvxException) ex;
            ErrorCode errorCode = svxException.getSvxExceptionDetail().getErrorCode();
            ErrorResponse errorResponse = new ErrorResponse(errorCode,svxException.getSvxExceptionDetail().getErrorDescription());
            resLog = new ResponseLog(reqLog,null,errorCode.getHttpStatus().value(),errorResponse,errorCode.getErrorType().toString());

        }
        else
        {
            LOGGER.error("Error: ", ex);
            resLog = new ResponseLog(reqLog, null, SYSTEM_ERROR_STATUS_CODE, ErrorType.SYSTEM_ERROR.toString(), ex.getMessage());

        }
        PERF_LOGGER.info(resLog.getLoggerString());
    }

}

但是，上面的代码给出了一个错误，即找不到自定义加载时间编织器。我不想在VM args中使用spring-instrumentation.jar。

也已经尝试过带有注释的基于类的方法，但是，在某些类加载后可能会加载该类，因此可能无效。

编辑：

添加了记录器和建议。在这里，我手动创建了一个代理，请参阅最后一行，我认为这不是一个好的解决方案。

使用Loadtime weaver与第三方jar类方法拦截器
