Using nested interfaces and mapper with MyBatis

Question

Is it possible to use nested mapper interface?:

package com.sample.package;

public class SampleService{

  public interface SampleMapper{
    public List<MyEntity> selectAllEntities();
  }
}

And if yes:

• where to put mapper xml file?
• what should be the name of xml file?
• what namespace shoud I put in mapper xml file for interface?

Answer 1

It works.

• The name of mapper must be SampleService$SampleMapper.xml.
• It must be placed in the SampleService dir.
• Namespace is com.sample.package.SampleService$SampleMapper.
