问题记录: no sapjco3 in java.library.path

对接厂家的SAP系统, 部署至linux环境时报下面的错误日志, 查了缺libsapjco3.so包
对应包下载地址 链接：https://pan.baidu.com/s/1YO0ZJq4J_SL9dI8VyuDsBg 提取码：8888
查了很多帖子是放在tomcat里, 现在springboot直接jar跑不方便加进去, 下面是配置到环境变量中

• 解决方案

  将sapjco3.jar和libsapjco3.so上传到服务器上, 配置 /etc/profile

  #java environment
  export JAVA_HOME=/usr/local/jdk/jdk1.8.0_181
  export CLASSPATH=.:${JAVA_HOME}/jre/lib/rt.jar:${JAVA_HOME}/lib/dt.jar:${JAVA_HOME}/lib/tools.jar:${JAVA_HOME}/lib/sapjco3.jar
  export PATH=$PATH:${JAVA_HOME}/bin
  
  # 我把libsapjco3.so上传到这个路径下了
  export LD_LIBRARY_PATH=/usr/local/jdk/jdk1.8.0_181/jre/lib/amd64/server
