Can typehandler be separated from mybatis？

[Ai-010]

I have already open sourced a framework called "mybatis-mp" based on mybatis. My entity class annotations need to rely on mybatis' typehandler, and I hope the annotation module of "mybatis-mp" can be made smaller and less dependent, but the typehandler property depends on mybatis dependencies. I hope mybatis can extract the typehandler from mybatis and make it a small module. My open source address is:

https://github.com/mybatis-mp/mybatis-mp

@documented
@retention(RetentionPolicy.RUNTIME)
@target(ElementType.FIELD)
public @interface TableField {
Class> typeHandler() default UnknownTypeHandler.class;
......
}

Mybatis mp is currently very user-friendly:

Pager<SysUser> pager= QueryChain.of(sysUserMapper) .like(SysUser::getUserName,"abc") .paging(Pager.of(1));

I cannot answer for others, but I think splitting a few things from the mybatis core making other modules would be a good improvement as we get a lot of requests for type handles we don't want to support but honestly we should. Me being a direct contributor, I even have type-handlers at work that should be in mybatis. So if others agree (2 or 3 others) then maybe that could happen.

Thank you for your reply；If this can be done, it is indeed beneficial for expanding based on mybatis, although some changes are needed for mybatis。

What does "separate type handlers" mean?
I'm not sure how you design your project, but we will not move the TypeHandler interface out of the core.

Just a suggestion，More friendly to open source frameworks based on MyBatis；I believe other open source projects also have similar requirements。
