java.lang.UnsatisfiedLinkError: no GurobiJni / Tomcat
我们正在尝试通过 Java Web 应用程序 运行 Gurobi，在 CentOS 中使用 Tomcat 服务器。系统变量定义：
declare -x GRB_LICENSE_FILE="/home/suporte/gurobi.lic"
declare -x GUROBI_HOME="/opt/gurobi752/linux64"
declare -x LD_LIBRARY_PATH="${LD_LIBRARY_PATH}:${GUROBI_HOME}/lib"
declare -x PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:$JAVA_HOME/bin:$GUROBI_HOME/bin"
Gurobi 和 Java 工作正常。应用程序在 Tomcat 中也能正常工作，但是当它调用 Gurobi 时，我们得到异常："java.lang.UnsatisfiedLinkError: no GurobiJni75 in java.library.path".

可以设置LD_LIBRARY_PATH指向Gurobi的.so文件存放目录，以及.jar文件存放目录
您还可以通过复制或链接从 Tomcat 访问 Gurobi jar 文件。

从您的调试 JSP 我们看到 ld.library.path 正确指向您的 GUROBI 库目录。
我们可以尝试为 java.library.path 添加一个系统 属性。在您的 Tomcat 安装中，使用以下内容编辑或创建 bin/setenv.sh 文件：

顺便说一句，我不知道你把 declare -x 放在哪里，但将它们存储在 bin/setenv.sh
