FdfsParamMapper报错

[maizuopaul]

在使用过程中，发现有一个异常,具体错误信息如下，好像这是一个潜在的bug，应该是在反射的时候出错了。不知道怎么修复了。

开日志看看

[maizuopaul]

申明一下我测试场景：连接池总大小500个，最大等待时间1000毫秒。我是在进行文件上传的压力测试，然后大概在上传文件到达大概3W个多一些的时候（3W多文件上传花费时间五分钟左右），就会报错,

后台打印的错误日志信息中提示：

1： 客户端连接服务端出现了io异常:socket io exception occured while receive content
2：收到不正确的命令代码65,99,120等各种奇怪的命令代码，
例如：
Caused by: java.io.IOException: recv cmd: 65 is not correct, expect cmd: 100
Caused by: java.io.IOException: recv cmd: 99 is not correct, expect cmd: 100
Caused by: java.io.IOException: recv cmd: 120 is not correct, expect cmd: 100

不知道是不是因为压力测试影响了socket连接和请求无法及时返回造成的？ 还是我的连接池需要进一步优化？

截取的关键日志信息如下：

检查一下服务端的日志，看看有没有错误。
Caused by: java.io.IOException: recv cmd: 65 is not correct, expect cmd: 100
Caused by: java.io.IOException: recv cmd: 99 is not correct, expect cmd: 100
Caused by: java.io.IOException: recv cmd: 120 is not correct, expect cmd: 100
服务端正确返回的报文应该是100，结果返回的是120

服务端版本号是多少？FDFS_V5.07当中120 不是标准的返回报文。

[weiyi1125]

请问是如何解决的？

[procedureDog]

怎么解决的？

[ylfmsn]

咋解决的？

[tobato]

更新最新的客户端试试

[ylfmsn]

1.26.7吗？

[tobato]

是的，现在用的哪个版本？

[ylfmsn]

fastdfs 5.05，FdfsDFS_Client 1.26.7，Spring boot 2.1.9.RELEASE，uploadImageAndCrtThumbImage方法第一次提交图片时成功，再次提交时就会报上面recieve content error，read timeout，command error之类的错...

[tobato]

方便的化，相关代码贴一下看看，还有错误日志

[Yikaba]

我使用的是1.26.7版本，多线程情况下时不时的报错：错误如下

FdfsParamMapper

@Yikaba 把日志打开跟踪看一下

FdfsResponse.decodeContent(InputStream in, Charset charset) throws IOException {
        // 如果有内容
        if (getContentLength() > 0) {
            byte[] bytes = new byte[(int) getContentLength()];
            int contentSize = in.read(bytes);
            // 获取数据
            if (contentSize != getContentLength()) {
                throw new IOException("读取到的数据长度与协议长度不符");
            }
            return FdfsParamMapper.map(bytes, genericType, charset);
        }
        return null;
    }

得看下服务端返回的信息是什么？ 目前怀疑服务端返回的数据格式可能有问题，导致解开报文错误。
