Dear Community,
We are pleased to announce the release of MyBatis 3.5.0.
This version requires Java version 8 and later.
The below is the list of user visible changes.
Enhancements:
- Avoid 'Illegal reflective access' warning on JDK 9+. #1156
- Added Automatic-Module-Name : org.mybatis #1199
- Support java.util.Optional as return type of mapper method. #799
- Avoid unnecessary wasNull() calls from the built-in type handlers. #1244
- It is now possible to specify columnPrefix in constructor arguments. #968
- Improved reliability when searching constructor for auto-mapping. #1277
- It is now possible to access private, package private and protected members in OGNL expressions. #1258
- Throw exception if the specified keyProperty is not found when assigning generated keys. #1250
- Added a type handler for SQLXML data type. #1221
- <set /> tag now trims the leading comma. #21
- Infer <case /> tag's resultType from the enclosing resultMap. #486
- Combination of @CacheNamespace and <cache-ref /> does not throw exception anymore. #1194
- Support Log4J 2.6+. #1210
- Slightly improved compatibility with drivers that only support JDBC 3 API. #1386
- Upgraded testing framework to JUnit 5. #1425
Bug fixes:
- OffsetDateTimeTypeHandler, OffsetTimeTypeHandler and ZonedDateTimeTypeHandler loses time zone information. #1081
- Avoid SQLException when using Cursor with Db2. #1345
- Avoid exception when using Cursor with ReuseExecutor. #1351
- RowBounds with out-of-range offset causes SQLException on Db2. #1355
- Specified logging implementation is not used in some classes. #1272
- Unable to resolve javaType for <association />. #1381
- Deeply nested (3+ levels) result map could cause IllegalArgumentException. #1176
- Generic type parameter is not correctly resolved when the class hierarchy is deeper than 3 levels. #1260
Please be aware that there also are some backward incompatible changes since the last release 3.4.6.
- 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. #1244
- 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
