http://mina.apache.org/ |
2、将依赖包添加到工程目录下(在工程目录下创建libs(directory目录))
3、将 slf4j-api-1.7.26.jar 和 mina-core-2.0.21.jar 依赖包添加到libs目录下
4、给这两个文件和工程绑定关系，方法：选中两个文件，右击，选择 Add as Library
代码实现
服务端

客户端1
1.可以使用window自带的telnet工具和服务器连接，并进行通信
首先打开Telnet，在控制面板中，打开程序和功能，在打开 （打开或关闭windows 功能），选中Telnet 客户端 ，确定
测试：控制台上输入 telnet localhost(服务器的ip地址) 8080(服务器的端口) ，即可
客户端2
2.自己写客户端程序
