jdbc - 使用 Glassfish 连接到 h2 数据库

Question

我正在使用 Glassfish 应用程序服务器开发 Web 应用程序。
我已经安装了 H2 DB，现在尝试在 glassfish 中定义一个连接池，但是在尝试 ping 数据库时它失败了。

这是我所做的:

安装了 H2 DB 并创建了一个新的 DB(服务器模式)。

我在 pom.xml 中添加了一个 H2 maven 依赖项:

<dependency>
    <groupId>com.h2database</groupId>
    <artifactId>h2</artifactId>
    <version>1.3.166</version>
</dependency>

将 H2 jar 文件 (h2-1.3.166.jar) 复制到我的 glassfish 库:C:\glassfish3\glassfish\lib

登录 glassfish admin gui 并创建以下 jdbc 连接:

资源类型:javax.sql.DataSource

数据库驱动供应商:H2

数据源类名:org.h2.jdbcx.JdbcDataSource

我的“附加属性”是:

用户:my_db_user

密码:my_db_password

url: jdbc:h2:tcp://localhost/~/my_db_name;AUTO_SERVER=TRUE

当我尝试 ping 此连接时，它失败并显示以下消息:

myCpool 的 Ping 连接池失败。类名错误或类路径未设置为:org.h2.jdbcx.JdbcDataSource 请检查 server.log 以获取更多详细信息。

我错过了什么吗？
任何帮助表示赞赏!

Answer 1

ClassNotFoundException: org.h2.jdbcx.JdbcDataSource意味着 H2 JDBC 驱动程序不在类路径中。我不太了解 Glassfish，但它似乎不在类路径中。其他数据库驱动程序似乎也发生了类似的问题，for example MySQL (需要将 .jar 文件添加到 /glassfish/domains/[domainname]/lib/ext )

您需要使用不同的数据库 URL:

jdbc:h2:~/my_db_name;AUTO_SERVER=TRUE

As described in the documentation, the automatic mixed mode不需要或使用服务器 URL(以 jdbc:h2:tcp:// 开头的 URL)
