Apache Mina use the small note

Introduction to the use of small notes Apache Mina is a network application framework that helps users develop high-performance and highly reliable network applications. It provides an asynchronous API that is abstracted from Java NiO in different transmissions such as TCP/IP and UDP/IP. Environment for JDK1.6+FREEBSD9 (64bit) +apache-mina-2.0.7+vim First is the configuration of environment variables

setenv java_home "/usr/local/diablo-jdk1.6.0/"
setenv java_bin "/usr/local/bin/"

In addition to SLF4J, this is the log library that Mina needs to use.

Exception handling

Docking the received data for business processing, where we return a current date regardless of what information is received

Handling when the connection is idle
public void Sessionidle (iosession session, Idlestatus status) throws Exception {
