A brief description: The use of Java NIO to develop network communication is relatively fast and aspect. Because he can listen to client connections without blocking, the event-based mechanism can be used in Java NiO for non-blocking communication when something new When registering, we only need to get new events through the event listening mechanism Simply put,

Out.close () and Bufferreader.close () to Client.shutdownoutput () and Client.shutdowninput (), and there will be no problem with the socket being closed directly.Socket.close (), input and output streams are off, and sometimes you want to just close one of the input or output streams->socket semi-close method,Shutdowninput (): Close the input stream onlyShutdownoutput (): Turn off the output stream onlyIf you put bufferreader.close () and Out.close () at the end of this question, the server wi

The most common database connection technology in Java isJDBC. At present, almost all mainstream databases provide corresponding JDBC drivers, which can be simply understood.. NET database client DLL ,. net. If netframework does not support databases by default (such as sqllite and MySQL), you must download a dedicated database client DLL file and add a referen

RABBITMQ to achieve Hello World is actually very simple.

This library can be applied to a variety of Java virtual machines to access network resources that follow the CIFS/SMB Network Transport protocol. Similar to the Java.io.File interface form, proved to be effective and easy to use in multi-threaded
