Question

我使用mule和jersey从ftp服务器下载文件，下载小文件没问题，大于100M的文件会在ftp服务器中出错并且不再下来，我写了一个jersey web项目并在tomcate中运行，可以下载600M大文件。 ftp服务器错误是：

下载球衣代码

InputStream inputStream = ftpTransferUtil.download(ftpClient.getClient(), ftpFilePath); 
FormDataBodyPart fdbp = new FormDataBodyPart("payload",inputStream, MediaType.APPLICATION_OCTET_STREAM_TYPE);
FormDataMultiPart formDataMultiPart = new FormDataMultiPart();
formDataMultiPart.bodyPart(fdbp);
formDataMultiPart.field("app_id", appId);
//formDataMultiPart.field("file_size", file.length() + "");
formDataMultiPart.field("version", version);
formDataMultiPart.field("postfix", postfix);
formDataMultiPart.field("file_name", ftpFileName);
// 返回FormDataMultiPart对象
response = javax.ws.rs.core.Response.ok(formDataMultiPart).build();

mule jersey配置

<jersey:resources doc:name="REST Service">
        <component>
            <spring-object bean="fileTransferRest" />
        </component>
</jersey:resources>

堆栈跟踪中没有一个Mule类：看起来问题来自Apache FTP库。您可以将ftpTransferUtil配置为更长的超时时间吗？
