Liferay 使用 H2 数据库-优快云博客

本文介绍如何在Liferay中配置使用H2数据库，包括下载H2数据库、修改配置文件及编译打包等步骤。适用于希望了解Liferay与H2数据库集成细节的技术人员。

摘要生成于 C知道，由 DeepSeek-R1 满血版支持，前往体验 >

我们以tomcat5.5.27 和 portal trunk version 34830 举例.

下载H2数据库
官网http://www.h2database.com

将h2-x.x.x.jar放到tomcat/common/lib/ext

修改portal-ext.properties文件设置jdbc

#
# H2
#
jdbc.default.driverClassName=org.h2.Driver
jdbc.default.url=jdbc:h2:${liferay.home}/data/h2/lportal;DB_CLOSE_ON_EXIT=FALSE
jdbc.default.username=sa
jdbc.default.password=

打补丁

编译打包发布portal-impl.jar.

启动tomcat

应该就能看到Liferay在使用h2数据库
