The difference between Mybatis and Mybatis Plus

Mybatis-Plus is an enhancement tool for Mybatis. It is only enhanced on the basis of Mybatis. Without changes, MyBatis-Plus supports all Mybatis native features, so the introduction of Mybatis-Plus will not have any impact on the existing Mybatis architecture.

MyBatis-Plus Advantages

1. Few dependencies: only rely on Mybatis and Mybatis -Spring.

2. Low loss: basic CURD will be automatically injected upon startup, with basically no performance loss, and direct object-oriented operation.

3. Prevent Sql injection: Built-in Sql injection stripper can effectively prevent Sql injection attacks.

4. Universal CRUD operations: Built-in universal Mapper and universal Service can realize most CRUD operations of a single table with only a small amount of configuration. It also has powerful conditional constructors to meet various usage needs.

5. Multiple primary key strategies: supports up to 4 primary key strategies (including distributed unique ID generator), which can be freely configured to perfectly solve the primary key problem.

6. Support hot loading: the XML corresponding to Mapper supports hot loading. For simple CRUD operations, it can even be started without XML

7. Support ActiveRecord: support ActiveRecord form calling, entity classes only You need to inherit the Model class to implement basic CRUD operations

8. Support code generation: Use code or Maven plug-ins to quickly generate Mapper, Model, Service, and Controller layer codes (generate custom files to avoid developing duplicate code) , supports template engines, has many custom configurations, etc.

9. Support custom global universal operations: support global universal method injection (Write once, use anywhere).

10. Support automatic escaping of keywords: Support automatic escaping of database keywords (order, key...), and you can also customize keywords.

11. Built-in paging plug-in: Based on Mybatis physical paging, developers do not need to care about specific operations. After configuring the plug-in, writing paging is equivalent to ordinary List query.

12. Built-in performance analysis plug-in: It can output Sql statements and their execution time. It is recommended to enable this function during development and testing, which can effectively solve slow queries.

13. Built-in global interception plug-in: Provides intelligent analysis and blocking of full table delete and update operations to prevent misoperations.

14. By default, the class name of the entity class is searched for the table in the database. Use the @TableName(value="table1") annotation to specify the table name, and @TableId to specify the primary key of the table. If the field is consistent with the field name in the table No annotation is required if consistent.
