SAPJCO3升级3.1后报错java.lang.UnsatisfiedLinkError: sapjco3.dll解决

部署JCO3.0版本不报错

部署JCO3.1版本执行sapjco3.jar报错如下

java.lang.ExceptionInInitializerError: JCo initialization failed with java.lang.UnsatisfiedLinkError: C:SAPJCOsapjco3.dll: Can't find dependent libraries

原因

SAPJCO官方站点
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811版本JRE，并需要安装MS VS2013 C++运行库

效果

安装完运行库重新运行sapjco3.jar,成功
