Java整合fastDFS上传文件需要配置springmvc配置文件及其它事项

上传时500错误，还有文件下载时的相关jar包记得倒全。

一开始报错以为路径不对

org.csource.common.MyException: item "tracker_server" in /D:/IADA_workspace/FastDfsTest/target/FastDfsTest-1.0-SNAPSHOT/WEB-INF/classes/config.conf not found后

后来发现是配置文件中我加了前缀fastdfs.去掉就好了直接是tracker_server

还有记得配置服务器端storage.conf的tracker地址必须是公网，还有nginx-fdfs的也是，不然会连接超时
