Camel + MyBatis + Apache Aries [英] Camel + MyBatis + Apache Aries

问题描述

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 Service Mix 5.0.1.我使用了引入 3.2.4.RELEASE 的 features-install spring-mybatis.我的 SqlMapConfig 文件只包含有关 typeHandlers 和 typeAliases 的信息.

I'm following the setup guide located at: Camel MyBatis Integration Guide. I am using Service Mix 5.0.1. I used features-install spring-mybatis which pulled in 3.2.4.RELEASE. My SqlMapConfig file only contains information about the typeHandlers and typeAliases.

当我启动 service mix 然后启动我的应用程序时，我收到以下堆栈跟踪:

When I start service mix and then start my app I receive the following stack trace:

推荐答案

您使用的指南是针对 spring 而不是 白羊座蓝图，这是问题的主要来源.mybatis-spring 用于集成，它使用 spring 特定的东西.

The guide you are using is for spring not Aries blueprint and this is the main source of the problem. mybatis-spring is used for integration and it uses spring specific things.

问题在于SqlSessionFactoryBean 的configLocation 属性.它应该是 spring org.springframework.core.io.Resource.如果您 使用前缀 给出提示.Aries 对 spring 一无所知，也没有内置从 String 到 spring Resource 的转换器.

The problem is with configLocation property of SqlSessionFactoryBean. It should be spring org.springframework.core.io.Resource. Spring can automatically convert string to Resource if you use prefix to give a hint. Aries knows nothing about spring and doesn't have built in converter from String to spring Resource.

有两种方法可以解决这个问题:

There are two options how to tackle this:

1. 将Resource实现bean注入到SqlSessionFactoryBean而不是字符串
2. 实现您自己的org.osgi.service.blueprint.container.Converter，它将接受字符串并返回Resource 实现.转换器应作为常规 bean 添加到上下文中，Aries 将在需要时使用它进行转换.在这种情况下，SqlSessionFactoryBean 的定义没有改变.

1. inject Resource implementing bean to SqlSessionFactoryBean instead of string
2. implement your own org.osgi.service.blueprint.container.Converter which will take string and return Resource implementation. The converter should be added to context as regular bean and it will be used by Aries for conversion when needed. In this case definition of SqlSessionFactoryBean is not changed.

在这两种情况下，您都可以使用 org.springframework.core.io.ClassPathResource 或自己实现 Resource.

In both cases you may use org.springframework.core.io.ClassPathResource or implement Resource yourself.
