如何浏览嵌入式H2数据库中的已添加数据

Question

我使用了用于WSO2 Gov Registry 4.6.0的开箱即用的H2嵌入式数据库,并在那里添加了许多条目.我试图查看数据库中的表中的数据,但不知何故看不到表.

我登录了嵌入式H2数据库,但只看到系统表,没有我添加到注册表的表或数据.

如何访问数据库中的REG_*和UM_*表以查看数据？

我试图在H2 db浏览器和DBVisualizer中查看表,但无法在两者中看到表和数据.

所有WSO2产品都默认随H2数据库一起提供.

通过在carbon.xml中启用H2DatabaseConfiguration可以轻松实现这一点.

1. 转到CARBON_HOME/repository/config
2. 打开carbon.xml文件.
3. 粘贴H2DatabaseConfiguration如下.(不要取消注释H2DatabaseConfiguration,它 只是粘贴在代码下面)

<H2DatabaseConfiguration>
        <property name="web"/>
        <property name="webPort">8082</property>
        <property name="webAllowOthers"/>        
</H2DatabaseConfiguration>

4. 启动服务器.
5. 将浏览器指向 http://localhost:8082
6. 填写JDBC URL,用户名和密码,如下所示.
   • JDBC URL:jdbc:h2:/ repository/database/WSO2CARBON_DB
   • 用户名:wso2carbon
   • 密码:wso2carbon

希望这可以帮助!
