请查阅 3.5.0 milestone page 的完整的变更列表.

请注意自从3.4.6版本后有一些向后的不相容的变化:

• Specifying keyProperty is now mandatory when using  useGeneratedKeys . If you relied on the implicit default value (="id"), generated keys will be silently ignored.  #1198

• Using Cursor now requires a driver that supports JDBC 4.1 API.  #1351

• If you extended org.apache.ibatis.type.BaseTypeHandler , you might need to add  wasNull() check in your type handler.  #1144

• The default resultSetType value has been changed from  FORWARD_ONLY to  UNSET . This is applied only to annotation based mappers (for XML based mappers, the default is/was  UNSET ).  #1334

• If you extended org.apache.ibatis.transaction.jdbc.JdbcTransaction for some reason, the property  autoCommmit has been renamed to  autoCommit .  #941
