MyBatis 3.5.0 发布，Java 数据持久层框架

  

MyBatis 3.5.0 需要Java 8 及以后版本.

增强:

• 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

• Allow accessing private, package private and protected members in OGNL expression. #1258

• <set /> tag now trims the leading comma. #21

• Infer <case /> tag's resultType from the enclosing resultMap. #486

• Allow specifying columnPrefix in constructor mapping. #968

• 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 修复:

• 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

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
