问题


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.

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

回答1:


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.

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.

There are two options how to tackle this:

  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.

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