SAPJCO3升級3.1後報錯java.lang.UnsatisfiedLinkError: sapjco3.dll解決

部署JCO3.0版本不報錯

部署JCO3.1版本執行sapjco3.jar報錯如下

java.lang.ExceptionInInitializerError: JCo initialization failed with java.lang.UnsatisfiedLinkError: C:\SAPJCO\sapjco3.dll: Can't find dependent libraries

原因

SAPJCO官方站點
The SAP Java Connector 3.1 requires a JDK/JRE 8 or 11. In addition, the SAP Java Connector 3.1 running on Windows operating systems requires the Microsoft Visual Studio 2013 C/C++ runtime libraries to be installed on the system.
JCO3.1版本需要8\11版本JRE，並需要安裝MS VS2013 C++運行庫

效果

安裝完運行庫重新運行sapjco3.jar,成功
