nginx配置如下：

location /log/ {
    #禁止浏览器直接访问
    internal;
    limit_rate 200k;
    alias /root/data/;
    error_page 404 =200 @backend;
}
location @backend {
    proxy_pass http://10.222.138.16:8086/openapi/open$request_uri;
    proxy_redirect off;
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
location /openapi/ {
    proxy_pass http://10.222.138.16:8086/$request_uri;
}

Java代码如下：

//httpResponse.setHeader("Content-Disposition", "attachment; filename=\""+filename+"\"");
//httpResponse.setHeader("Content-Type", "application/octet-stream");
//httpResponse.setHeader("X-Accel-Redirect", "/log/"+url);
HttpHeaders header = new HttpHeaders();
header.add("Content-Disposition", "attachment; filename=\""+filename+"\"");
header.add("Content-Type", "application/octet-stream");
header.add("X-Accel-Redirect", "/log/"+url);

请求地址为：

http://10.222.138.180/log/download?access_token=a68cafa8b80f08c7db2af5b654435dd2

日志文件在目录/root/data下

通过wget下载时可以加上参数--content-disposition，下载的文件名就是Java代码设置的filename（对wget版本要求 >= 1.15）
