This allows annotated selects to reuse resultmaps that are defined in XML. This annotation will override any@Resultsor@ConstructorArgs` annotation if both are specified on an annotated select.@ResultTypeMethodN/AThis annotation is used when using a result handler. In that case, the return type is void so MyBatis must have a way to determine the type of object to construct for each row. If there is an XML result map, use the @ResultMap annotation. If the result type is specified in XML on the ` Night Mode映射申明样例这个例子展示了如何使用 @SelectKey 注解来在插入前读取数据库序列的值：@Insert("insert into table3 (id, name) values(#{nameId}, #{name})")@SelectKey(statement="call next value for TestSequence", keyProperty="nameId", before=true, resultType=int.class)int insertTable3(Name name);这个例子展示了如何使用 @SelectKey 注解来在插入后读取数据库识别列的值：@Insert("insert into table2 (name) values(#{name})")@SelectKey(statement="call identity()", keyProperty="nameId", before=false, resultType=int.class)int insertTable2(Name name);
