配置
Windows ---------------------------------------------------- Choose your binary build - x64 or x86 (based on which version of the JVM you are installing to) NOTE: You MUST match your architecture. You can‘t install the i386 version on a 64-bit version of the JDK and vice-versa. For a JDK installation: Copy RXTXcomm.jar ---> <JAVA_HOME>\jre\lib\ext Copy rxtxSerial.dll ---> <JAVA_HOME>\jre\bin Copy rxtxParallel.dll ---> <JAVA_HOME>\jre\bin Linux ---------------------------------------------------- Choose your binary build - x86_64 or i386 (based on which version of the JVM you are installing to) NOTE: You MUST match your architecture. You can‘t install the i386 version on a 64-bit version of the JDK and vice-versa. For a JDK installation on architecture=i386 Copy RXTXcomm.jar ---> <JAVA_HOME>/jre/lib/ext Copy librxtxSerial.so ---> <JAVA_HOME>/jre/lib/i386/ Copy librxtxParallel.so ---> <JAVA_HOME>/jre/lib/i386/ NOTE: For a JDK installation on architecture=x86_64, just change the i386 to x86_64 above.

调去线程
public String Start() { AutoOutInStoreHandler runner1 = new AutoOutInStoreHandler(); Thread thread1 = new Thread(runner1); thread1.start(); }
properties文件定义
startToendPort=COM7
endPort=COM6
//获取properties文件定义选择的端口号
ResourceBundle resource = ResourceBundle.getBundle("port");//port为属性文件名，放在包com.mmq下，如果是放在src下，直接用test即可 String port = resource.getString("startToendPort");
