As far as the MyBatis goes, I gave it a look and it quite similar to Hibernate. Some names of the annotations are different but they do the same thing. I wouldn't say it easier than Hibernate, but that is just my thought. maybe somebody that has experience with Mybatis should say something
If you trying to decide on which way to go - hibernate or mybatis. I would say it depends - in which stage of the project you are in. If you are in control of the Class model - starting from the scratch, then you could very well design your classes in line with Hibernate principles. If you are trying to do one off thing in existing application which is following a different db framework, then I would say using mybatis would be very helpful. Also Mybatis is a nobrainer in terms of maintenance, you could directly work/concentrate on the SQL queries - banking on your SQL knowledge. It would be very easy for a new joinee in the team to pickup mybatis when compared to hibernate. While for Hibernate, there is a learning curve involved. Especially if there are some complex joins involved in the application, then Hibernate is going to be quite a challenge though. With mybatis you could come up with the exact query in any query analyzer and use it directly in the mapper file.
