一、关于在tomcat在server.xml的配置文件上传大小20M的限制 – maxPostSize=”20971520″

<Connector port="8080" protocol="HTTP/1.1"
                           maxThreads="200" 
                           minSpareThreads="25" 
                           maxSpareThreads="100"
                           acceptCount="200"
                           maxPostSize="20971520"
                           connectionTimeout="30000"
                           enableLookups="false"
                           disableUploadTimeout="true"
                           compression="on"
                           compressableMimeType="text/html,text/xml,text/plain,text/css,
                           text/javascript,text/json,application/x-javascript,
                           application/javascript,application/json"
                       noCompressionUserAgents="gozilla, traviata"
               redirectPort="8443" />

二、在nginx的nginx.conf的配置文件上传大小为20M – client_max_body_size 20m;

location /gw/file/upload {
            proxy_pass http://127.0.0.1/upload;
            proxy_redirect  off;
            proxy_set_header        Host    $http_host;
            proxy_set_header        X-Real-IP       $remote_addr;
            proxy_set_header        X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header   Cookie $http_cookie;
            client_max_body_size   20m;
}
