Jboss Fuse 中的 H2 数据库

Question

我正在尝试创建一个使用 h2 数据库的包。我正在使用 felix maven 插件。

我的felix配置是这样的

<Import-Package>*,org.h2.Driver,org.h2.*</Import-Package>
<DynamicImport-Package>*</DynamicImport-Package>

但是我遇到了这样的异常

但我对 mysql 数据库也做同样的事情，它工作正常。但我想在我的包中使用 h2，我也面临着与 hsql 数据库相同的问题。好像我错过了什么，请帮助我。

Answer 1

您的异常与 felix 插件无关，依赖 jar 和数据源的必要属性不存在.. 将属性添加到您的数据源，如下所示。

    <property name="url" value="jdbc:h2:<url>"/>
    <property name="username" value="user"/>
    <property name="password" value=""/>
    <property name="driverClassName" value="org.h2.Driver"/>

并添加依赖项

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