java.lang.UnsatisfiedLinkError: no rxtxSerial in java.library.path的解决

归根结底还是缺少文件，要下载rxtxSerial.dll和rxtxParallel.dll文件，Go to Project -> properties -> Java build path ->Find your RXTXcomm.jar. Click on + to open the JAR's properties. Select Native library location and edit it to point to RXTX's shared library (.DLL, .so, .dylib).
