嗨，伙计们，我在 Karaf 4.3.6（最近的升级）中的数据源有一些问题，我希望有人能阐明我在这里做错了什么。

升级前

Karaf 有以下服务（org.osgi.service.jdbc.DataSourceFactory）：

[org.osgi.service.jdbc.DataSourceFactory]
-----------------------------------------
 osgi.jdbc.driver.class = com.microsoft.sqlserver.jdbc.SQLServerDriver
 osgi.jdbc.driver.name = com.microsoft.sqlserver.mssql-jdbc-native
 osgi.jdbc.driver.version = 6.2.2.jre8
 service.bundleid = 46
 service.id = 219
 service.scope = singleton
Provided by :
 Microsoft JDBC Driver for SQL Server (46)

[org.osgi.service.jdbc.DataSourceFactory]
-----------------------------------------
 osgi.jdbc.driver.class = com.microsoft.sqlserver.jdbc.SQLServerDriver
 osgi.jdbc.driver.name = Microsoft JDBC Driver for SQL Server
 osgi.jdbc.driver.version = 7.4
 service.bundleid = 47
 service.id = 223
 service.scope = singleton
Provided by :
 Microsoft JDBC Driver for SQL Server (47)

[org.osgi.service.jdbc.DataSourceFactory]
-----------------------------------------
 osgi.jdbc.driver.class = com.microsoft.sqlserver.jdbc.SQLServerDriver
 osgi.jdbc.driver.name = mssql
 service.bundleid = 157
 service.id = 252
 service.scope = singleton
Provided by :
 OPS4J Pax JDBC MSSQL Driver Adapter (157)
Used by:
 example-project(173)
 OPS4J Pax JDBC Config (38)

我的项目蓝图包含以下内容：

    <bean id="sqlComponent" class="org.apache.camel.component.sql.SqlComponent">
    <property name="dataSource" ref="exampleSQLServerDataSource"/>
</bean>

<service id="c1SQLDataSource" interface="javax.sql.DataSource" ref="exampleSQLServerDataSource">
    <service-properties>
        <entry key="osgi.jndi.service.name" value="exSQLDataSource"/>
    </service-properties>
</service>

<bean id="exampleSQLServerDataSource" factory-ref="sqlServerDataSourceFactory" factory-method="createDataSource">
  <argument>
    <props>
      <prop key="databaseName">${ex.db.dbname}</prop>
      <prop key="user">${ex.db.user}</prop>
      <prop key="password">${ex.db.password}</prop>
      <prop key="portNumber">${ex.db.port}</prop>
      <prop key="serverName">${ex.db.host}</prop>
    </props>
  </argument>
</bean>

<reference id="sqlServerDataSourceFactory" interface="org.osgi.service.jdbc.DataSourceFactory" filter="(objectClass=org.osgi.service.jdbc.DataSourceFactory)(osgi.jdbc.driver.name=mssql)"/>

使用此配置，我的项目在安装时运行良好/我可以将 camel-sql 组件与我的数据源一起使用。

升级后

对 karaf depensancys 的更改意味着 mssql 工厂不再可用（即使在启动 pax-jdbc-mssql 的功能时）

我的项目蓝图包含以下内容：

我修改了我的 blueprint.xml 以使用 jdbc:ds-factories 中可用的其他连接之一，但我看到以下错误，抱怨缺少安装要求

如果我正确阅读了错误消息，则您的 Karaf 出于某种原因缺少捆绑启动时sqlserver激活器应提供的SQLServerDataSourceFactory服务。

如果您从 Apache Karaf 版本 4.2.x 升级到 4.3.6，则可能是pax-jdbc-mssql 功能安装的包版本mssql-jdbc/9.4.0.jre8可能与 Java 11 不兼容。

Apache Karaf 4.3.x 支持 JDK 11+，而 4.2.x 适用于 JDK 8、9 和 10。Apache karafs下载页面上有一个方便的表格，显示哪个版本支持什么。关于 4.3.x 的 JDK 8 支持的邮件

由于功能pax-jdbc-mssql仅包含 mssql-jdbc 包和 pax-jdbc-spec 功能，您可以尝试使用 jre11 版本的 mssql-jdbc 包单独安装它们。

例子：

feature:install pax-jdbc-spec
bundle:install mvn:com.microsoft.sqlserver/mssql-jdbc/9.4.1.jre11

由于 9.4.1 版本存在一些漏洞，如果可能，您还可以尝试升级到更新的10.2.0.jre11版本。
