Java Camel Mybatis开放会话异常

我使用的是Camel Mybatis版本2.12.0.redhat-610379，当我们试图通过karaf容器启动包时，会抛出以下异常。请给我一些建议

org.apache.ibatis.exceptions.PersistenceException:

打开会话时出错。原因：java.lang.NullPointerException 原因：java.lang.NullPointerException 原因：java.lang.NullPointerException 位于org.apache.ibatis.session.defaults.DefaultSqlSessionFactory.openSessionFromDataSource（DefaultSqlSessionFactory.java:83）[280:org.mybatis.mybatis:3.2.5] ... 32多

正确创建了连接和配置，我犯的错误是在bean.xml中，我使用了

myBatis

bean id，我输入的camel route为

myBatis

，由于区分大小写，没有创建环境，很抱歉。

看起来myBatis没有

环境设置。可能数据源的设置不正确。您是否设置了正确的jdbcUrl？当我们从这个bean.xml创建连接时，我们没有在SqlMapConfig.xml中定义任何连接，如果我通过SqlMapConfig.xml创建连接，它就会工作。我注意到您在
SqlSessionFactoryBean
上显式调用
getObject
。这看起来不正确。由于
SqlSessionFactoryBean
实现了
FactoryBean
Spring接口，因此bean的类型已经是
SqlSessionFactory
。例如，请参阅文档SqlSessionFactoryBean创建会话，但在我的例子中，我必须为驼峰路由中使用的
MyBatisComponent
创建bean。我在camel mybatis中查看过，大多数建议的想法和代码都与上面的类似
<bean id="ds" class="com.mchange.v2.c3p0.ComboPooledDataSource">
     <property name="driverClass"  value="oracle.jdbc.driver.OracleDriver"/>
