Liferay DXP 7.2侦听器启动失败(干净版本)

Question

Liferay DXP7.2无法使用OpenJDK启动(干净版本)。不使用任何IDE，它是WindowsServer2016版本(不认为服务器版本会出现任何问题)刚刚在E:\PROJECT_NAME\liferay-dxp-tomcat-7.2.10.1-sp1-slim-20191009103614075\liferay-dxp-7.2.10.1-sp1\tomcat-9.0.17\bin下启动了E:\PROJECT_NAME\liferay-dxp-tomcat-7.2.10.1-sp1-slim-20191009103614075\liferay-dxp-7.2.10.1-sp1\tomcat-9.0.17\bin。使用环境变量(JAVA_HOME:C:\openjdk-13.0.1_windows-x64_bin\jdk-13.0.1)进行检查。看起来缺少任何依赖项或配置。需要帮助。

Answer 1

如果您查看Liferay DXP兼容性矩阵，您会发现Java13不在其中--它只是LTS版本。运行与兼容的版本，以消除此问题。请注意，只有TCK认证的OpenJDK构建是受支持的，您可能希望在版本的基础上验证这一点。

Answer 2

此错误是由于不兼容的JDK设置造成的。因此，您需要更改为兼容的JDK。例: JDK8适用于救生筏-ce-门户-tomcat-7.2.1-ga2。

在Windows中:将JAVA_HOME设置为JDK文件夹路径，将路径设置为JDK/bin文件夹路径。通过打开新的命令行窗口重新启动tomcat，它应该可以工作。
