briefest's Issues

通用逻辑优化 General logic optimization

• 去除主键强校验. 增加优化提示
• Remove the primary key strong check. Add optimization tips

怎么忽略某个字段

Current version

3.6.2

How did the problem arise? (Make sure the latest version also has problems!!)

怎么像mybatis-plus 的 @TableField(exist = false) 一样忽略某个字段?

分库分表查询

追踪差异更新支持乐观锁.Tracking difference updates support optimistic locking

• 当model类声明version时支持乐观锁更新. 更新成功version会自增1
• Optimistic lock updates are supported when the model class declares version. If the update is successful, the version will automatically increase by 1

How do I find community tasks

• How do I find community tasks

1。Mybatis modelhelper has the following two label issues, which are tasks that can be claimed first

Contribution Welcome
good first issue

2。If you particularly want and are suitable for solving problems in an issue or implementing a feature,You can find any mybatis modelhelper Committee for direct communication Issues claim and resolution process

   To confirm the claim, please reply @I will solve it@
   The fork warehouse is repaired, and then the merge request is submitted through the pull request. The related issues (# issues number) are included in the submitted information.After merging the pull request, you become the contributor of mybatis modelhelper. Please reply later“ https://github.com/ready To close @.After that, the tracker will close it.Those who claim more issues and make outstanding contributions to the community will vote at the mybatis modelhelper weekly  meeting to develop into committees.。

增加乐观锁version

通用api增加 version乐观锁update。

gourp_concat Function support

A new annotation supports group concat

3.6.3: java.lang.NoClassDefFoundError: org/reflections/Reflections

Current version

brief 3.6.3
jdk 17
spring boot 2.7.8

How did the problem arise? (Make sure the latest version also has problems!!)

brief-common 里面的reflections 设置为了 compile ,导致运行时缺少 org.reflections.Reflections

        <dependency>
            <groupId>org.reflections</groupId>
            <artifactId>reflections</artifactId>
            <version>0.9.12</version>
            <scope>compile</scope>
        </dependency>

Repeat steps

Your expectations

删除 org.reflections 的 <scope>compile</scope>

work around

手动添加org.reflections 依赖

BriefMapper 增加后置处理器. Add a post-processor for BriefMapper

• 用于控制BriefMapper初始化前后进行修改
• Allows you to modify the BriefMapper before and after initialization

brief支持spring-boot Support spring-boot

brief-spring-boot-starter

项目整体重新命名brief-jql

突出核心**简约sql.

多数据元切换Multi-datasource element switching,

1. 支持多数据源

去掉追踪差异更新特性. Remove the tracking difference update feature.

1. 在项目实战的过程中. 发现追踪差异更新降低了项目的可维护性. 代码的可阅读性. 误操作较高. 新人在不知情的情况下更新了DB.
2. In the process of actual project. Found that tracking variance updates reduced project maintainability. The readability of code. The new user updates the DB without knowing it.

支持oracle语法 Support oracle grammar

通用api增加逻辑删除

Model类支持自动识别差异更新. Model class supports automatic recognition of difference updates

• 提供自动识别更新开关. 如果打开状态则在调用set方法时会自动进行更新
• Provides automatic recognition update switch. If the state is open, it is automatically updated when the set method is called

慢查询统计

支持pgsql语法

分库分表 sub-datasource sub-table

The same coverage problem of join table fields

When the fields of two tables are the same, the field results with the same query results will be overwritten. Solution: the alias field should have the ID of the class. When mapping, it should be mapped according to the ID of the class

当查询两张表的字段相同时，查询的结果相同的字段结果会被覆盖。解决思路：别名字段要有类的标识，在映射时应根据类的标识进行映射

支持手动开启事务 Supports manually starting transactions

Lightweight version

Standalone mybatis. Version upgraded to lightweight. Independent of mybatis.

唯一key生成策略 Unique key generation policy

• 雪花 snowflake
• UUID
• 自增 auto-increment
• 自定义 user-defined

增加 saveOrModify功能在GeneralFun中。Added saveOrModify function to GeneralFun

支持json字段 support json colname

创建github.io说明文档

独立出来不依赖任何框架

• 需要重新命名

重构model数据渲染.提高映射性能. Refactoring model data rendering. Improve mapping performance. Avoid reflection.

Avoid the performance overhead of reflection

Concat annotation function support about joining together

＠Concat('xxx')// 默认是　concat(colName, 'xxx')
期望是colName　可以在左边concat(colName, 'xxx')，也可以在右边concat( 'xxx'，colName)。可以自由的选择

@ Concat ('xxx ')//The default is concat (colName,'xxx')
It is expected that colName can be concat on the left (colName, 'xxx') or concat on the right ('xxx', colName). Free choice

sql执行过滤器.

可以轻松掌握一个sql的执行生命周期. 执行前， 执行中，执行后。 都可以自定义处理

Model类是否要支持数据库字段强校验.Whether to support strong check of database fields

目前的model类中可以声明非表中字段的属性.

• 优点: 灵活性比较高.
• 缺点: 灵活性高导致可维护性差. 当非表字段属性过多时,对于新人代码阅读不友好.

解决方案:

• 在@BaseModel中增加一属性, 用来控制是否要Model属性与表字段强一致校验.
• 新加@NoneCol 表示非表字段
• 默认是否要强一致校验(暂未考虑好)
