使用Glassfish连接到h2数据库

标签： jdbc glassfish-3 h2

我正在使用Glassfish应用服务器开发一个网络应用。 我已经安装了H2 DB，现在尝试在glassfish中定义连接池，但是当尝试ping数据库时它失败了。

这是我做的：

  1. 安装了H2 DB并创建了一个新的DB（服务器模式）。

  2. 我在pom.xml中添加了H2 maven依赖项：

    <dependency>
    <groupId>com.h2database</groupId>
    <artifactId>h2</artifactId>
    <version>1.3.166</version>
</dependency>
  3. 将H2 jar文件（h2-1.3.166.jar）复制到我的glassfish lib：C：\ glassfish3 \ glassfish \ lib
  4. 登录到glassfish admin gui并创建以下jdbc连接：
    • 资源类型：javax.sql.DataSource
    • 数据库驱动程序供应商：H2
    • 数据源类名：org.h2.jdbcx.JdbcDataSource

    5. 我的“其他属性”是：

    • user：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请查看server.log以获取更多详细信息。

    完整的日志说：

    我错过了什么吗？ 任何帮助表示赞赏！

2 个答案:

答案 0 :(得分：5)

ClassNotFoundException: org.h2.jdbcx.JdbcDataSource表示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。似乎其他数据库驱动程序for example MySQL出现类似问题（.jar文件需要添加到/glassfish/domains/[domainname]/lib/ext）

您需要使用其他数据库网址：

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网址（以jdbc:h2:tcp://开头的网址）

答案 1 :(得分：0)

在服务器安装文件夹的以下路径中添加h2的驱动程序jar文件：

glassfish/domains/domain1/lib/ext
