我正在遵循位于以下位置的设置指南：Camel MyBatis 集成指南。我正在使用服务组合 5.0.1。我使用了 3.2.4.RELEASE 中的 features-install spring-mybatis。我的 SqlMapConfig 文件仅包含有关 typeHandlers 和 typeAliases 的信息。

当我启动服务组合然后启动我的应用程序时，我收到以下堆栈跟踪：

您使用的指南适用于 spring 而不是Aries 蓝图，这是问题的主要根源。mybatis-spring用于集成，它使用 spring 特定的东西。

问题在于 的configLocation属性SqlSessionFactoryBean。应该是春天org.springframework.core.io.Resource。Resource如果您使用前缀给出提示，Spring 可以自动将字符串转换为。Aries 对 spring 一无所知，也没有内置转换器 fromString到 spring Resource。

有两种方法可以解决这个问题：

  1. 注入Resource实现beanSqlSessionFactoryBean而不是字符串
  2. 实现你自己的org.osgi.service.blueprint.container.Converter，它将接受字符串并返回Resource实现。转换器应该作为常规 bean 添加到上下文中，并且 Aries 将在需要时使用它进行转换。在这种情况下，定义SqlSessionFactoryBean不会改变。

在这两种情况下，您都可以自己使用org.springframework.core.io.ClassPathResource或实现Resource。
