In my project with Play Framework and MyBatis-Guice, I have multiple datasources and they work fine. Until I try to inject somewhere SqlSessionFactory. After that I got the error:
Unable to create binding for org.apache.ibatis.session.SqlSessionFactory. It was already configured on one or more child injectors or private modules
bound at org.mybatis.guice.MyBatisModule.internalConfigure(MyBatisModule.java:116) (via modules: com.google.inject.util.Modules$OverrideModule -> services.modules.SomeBatisModule -> services.modules.SomeBatisModule$1)
bound at org.mybatis.guice.MyBatisModule.internalConfigure(MyBatisModule.java:116) (via modules: com.google.inject.util.Modules$OverrideModule -> services.modules.AnotherBatisModule -> services.modules.AnotherBatisModule$1)
If it was in a PrivateModule, did you forget to expose the binding?
How I can fix it?

I don't know if this is correct, but this solution worked:
public class SomeBatisModule extends PrivateModule {
@Override
protected void configure() {
protected void configure() {
...
expose(SqlSessionFactory.class).annotatedWith(Names.named("some-database"));
}
}
}
public class SomeService {
public SomeService(@Named("some-database") SqlSessionFactory sqlSessionFactory) {
...
}
}
