Java Distributed File Management system-mydfsserver

Dear Bo Friends, my name is Warkeway, good at Java and C + + language, now in Wuxi. Worked as a project manager, Java Programmer, Android development engineer, Java instructor. If there are technical problems we can discuss together. I qq:1058633117 QQ e-mail: [Email protected] Tel: 15295432682

This is the file Upload management system I wrote, the file upload system. Can be easily integrated in javaweb or other applications. Already open source on GitHub. The project is an app written in the Java language, and I'm named Mydfsserver, using a Java class library with sockets, DataOutputStream, DataInputStream, threads, thread pools, which are already used in some projects, and very stable.

GitHub Project Address: Https://github.com/believeus/MyDfsServer.git.

First step: Download the install Git tool.

Step two: Use the command git clone https://github.com/believeus/MyDfsServer.git to download the source code locally. (You won't need to add a base to git).

Step three: Integrate into the project.

Way one: Integrate spring in the Web environment
First step: Configured in the spring configuration file, the service starts with the Tomcat load Web App launch and shuts down as Tomcat shuts down

Step Two: Configure in Web. xml

Step three: Write Java code
First parameter: InputStream uploaded file stream the second parameter: extention: The suffix name of the file
String storepath= mydfstrackerserver.upload (InputStream, extention);


Mode two: Start as a separate service
First step: An executable Mydfsserver.jar file is generated after the Ant jar executes
Step Two: Java-jar Mydfsserver.jar
Mydfsserver.jar file with mydfs.properties file, IP and port related configuration can be configured
Default port 9999 host default 127.0.0.1 threads Worker default is 5 base path basepath default: e:/data/mydfs/store/
Step three: Write the client code to put Mydfsserver.jar into the client's environment variable
Mydfstrackerserver client=new mydfstrackerserver ("127.0.0.1", 9999);


Method Three: Hard-coded
If it is not in the spring Web environment, use the method in the code
0. Start the service
First parameter: Port number to start the second parameter: Picture storage address the third parameter: number of worker threads fourth parameter: Listening IP address
Mydfsstorageserver storageserver=new Mydfsstorageserver (9999, "D:/data/mydfs/store", 4, "127.0.0.1");
Storageserver.startserver ();
1. Upload a picture to get the path after uploading the image
Mydfstrackerserver client=new mydfstrackerserver ("localhost", 9999);
InputStream InputStream = new FileInputStream ("d:/20130412062742872.jpg");
String Storepath = Client.upload (inputstream, "JPG");
System.out.println (Storepath);
2. Get the uploaded picture data
Mydfstrackerserver client=new mydfstrackerserver ("127.0.0.1", 9999);
String url= "http://www.jobs.com/group/M00/EF/2C/3696-CCD2-43E7-9854-6B51F6AA2315.jpg?w=100&h=100";
InputStream inputstream=client.receivedata (URL);
3. Delete uploaded image data
Mydfstrackerserver client=new mydfstrackerserver ("127.0.0.1", 9999);
String url= "http://www.jobs.com/group/M00/78/79/53D9-34E2-4110-BDBA-8BF808E2C4BD.swf";
Boolean success = Client.removedata (URL);
System.out.println ("Delete condition:" +success);
