Question

我是OSGI开发的新手。我想在Fuse服务器中使用Spring JDBC将记录插入到DB中。我开发了独立的SpringJDBC代码，它运行良好。我已经转换为蓝图标准。在Fuse服务器中安装软件包时，我收到了下面提到的错误。我希望Fuse服务器中没有Spring jar。请帮我解决这个问题并感谢任何示例教程或代码。

服务器：Jboss Fuse 6.2.1

错误：

**Error executing command: Error installing bundles:
  Unable to start bundle file:My repositorypath/myapplication.jar Unresolved constraint in bundle homeloan [302]: Unable to resolve 302.0: missing requirement [302.0] osgi.wiring.package; (osgi.wiring.package=org.springframework.jdbc.core)**

Answer 1

从JBoss Fuse控制台，输入

features:install spring-jdbc

这将安装所需的包。快速检查

JBossFuse:karaf@root> exports | grep springframework.jdbc
    276 org.springframework.jdbc; version=3.2.12.RELEASE
    276 org.springframework.jdbc.core.simple; version=3.2.12.RELEASE
    276 org.springframework.jdbc.core.namedparam; version=3.2.12.RELEASE
    ....

将告诉您捆绑包276正在导出此类包。（软件包ID号可能会因安装而异）

如果您需要其他库，请查看features:list命令，它可能已经作为功能分发。

Answer 2

您需要安装所需的依赖项。

features:install camel-sql 
features:install camel-jdbc

我看到用户名和密码也丢失了。我和Oracle做过类似的事情。

<bean id="oracleConnectionCacheProperties" class="java.util.Properties">
    <argument>
        <props>
            <prop key="MinLimit" value="${database.connectionCache.minLimit}" />
            <prop key="MaxLimit" value="${database.connectionCache.maxLimit}" />
            <prop key="ValidateConnection" value="${database.connectionCache.validateConnection}" />
            <prop key="InactivityTimeout" value="${database.connectionCache.inactivityTimeout}" />
        </props>
    </argument>
</bean>

<bean id="oracleInstance" class="oracle.jdbc.pool.OracleDataSource" destroy-method="close">
    <property name="URL" value="${oracleDataSource.url}" />
    <property name="user" value="${database.user}" />
    <property name="password" value="${database.password}" />
    <property name="connectionCachingEnabled" value="true" /> 
    <property name="connectionCacheProperties" ref="oracleConnectionCacheProperties" />
</bean>

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

另外，您应该检查您的位置空间。

    xsi:schemaLocation="
   http://www.osgi.org/xmlns/blueprint/v1.0.0 http://www.osgi.org/xmlns/blueprint/v1.0.0/blueprint.xsd
   http://camel.apache.org/schema/blueprint http://camel.apache.org/schema/blueprint/camel-blueprint.xsd
