木有人遇到过这情况么！！

是不是压力负载大了才有这个问题呢？
如果是的话，请将线程池的核心线程数加大，默认才10，生产环境下可以调整为400.

    <rop:annotation-driven
            core-pool-size="${rop.corePoolSize}" <== 这个数值调整为400！
            max-pool-size="${rop.maxPoolSize}"
            queue-capacity="${rop.queueCapacity}"
            keep-alive-seconds="${rop.keepAliveSeconds}"
            upload-file-max-size="${rop.uploadFileMaxSize}"
            upload-file-types="${rop.uploadFileTypes}"
            thread-ferry-class="${rop.threadFerryClass}"
            sign-enable="${rop.signEnable}"
            ext-error-base-names="${rop.customErrorBasenames}"
            service-timeout-seconds="${rop.serviceTimeoutSeconds}"

            session-manager="sessionManager"
            app-secret-manager="appSecretManager"
            formatting-conversion-service="conversionService"/>

stamen 写道

core-pool-size 等几个参数也设置过好多情况，但是还是不行，我用apache-jmeter做了个压力测试，出错是有规律的，每提交一定次数请求大概6-7百次，然后请求就报错，连续6-7百次后，又能正常返回结果，然后反复这样！！

找到原因了，因为我的redis的异常引起的！！但是为啥没把原始错误抛出来啊？？
