数据库JDBC版本：GBase 8s JDBC V8.8 3.3.0_3
Mybatis-Plus版本： 3.4.3.2
JDK版本： jdk1.8.0_201

对象类型使用LocalDataTime时，报错误：

原因：
LocalDateTime是java8新增日期时间类型，在mybatis 3.4版本之后有对应的转换类org.apache.ibatis.type.LocalDateTimeTypeHandler，但数据库的jdbc驱动（jdk6）里IfxPreparedStatement.setObject(java.lang.String, java.lang.Class)中未实现该方法。
解决方法：
由于驱动是jdk6的，暂时还没有实现LocalDateTime，故需要在mybatis中对LocalDateTime进行转换。已知mybatis-typehandlers-jsr310专门提供了针对java8的新日期时间类型的转换类，所以将这个依赖加进来就好了，但是里面的转换类的包名和类名都和新版本的mybatis包的一致，所以在pom文件中其依赖必须添加在mybatis相关依赖之前，保证优先加载使用。
