在OSGI环境下使用MyBatis，TypeHandler不能正常加载

Question

请问各位是如何解决OSGI环境下MyBatis不能根据配置文件中的类全限定名加载TypeHandler呢？

例如：

 <delete id="deleteById" statementType="PREPARED">
    delete from ${tableName} where id in
    <foreach item="item" collection="guidList" separator="," open="(" close=")">
      #{item, typeHandler=com.example.GUIDTypeHandler}
    </foreach>
  </delete>

这时候会报错：

Caused by: java.lang.ClassNotFoundException: Cannot find class: com.example.GUIDTypeHandler
    at org.apache.ibatis.io.ClassLoaderWrapper.classForName(ClassLoaderWrapper.java:200)
    at org.apache.ibatis.io.ClassLoaderWrapper.classForName(ClassLoaderWrapper.java:89)
