Liferay DXP 7.2监听器启动失败（干净版）

Question

Liferay DXP 7.2 无法使用 OpenJDK 启动（干净版）。没有使用任何 IDE，它是 Windows Server 2016 版本（不要认为服务器版本会有任何问题）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 startup.bat。检查环境变量 (JAVA_HOME:C:\openjdk-13.0.1_windows-x64_bin\jdk-13.0.1)。似乎缺少任何依赖项或配置。需要帮助。

Answer 1

如果您查看 Liferay DXP compatibility matrix，您会发现 Java 13 不在那里 - 只有 LTS 版本。运行用一个兼容的版本来消除这个问题。请注意，仅支持经 TCK 认证的 OpenJDK 构建，您可能希望在版本之上验证这一点。

Answer 2

错误是由于 JDK 设置不兼容造成的。所以需要改成compatible JDK。例如：JDK8 适用于 liferay-ce-portal-tomcat-7.2.1-ga2.

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