MyBatis Generator Pros and Cons

MyBatis Generator is a tool used to automatically generate MyBatis persistence layer code, such as entity classes, Mapper interfaces, and corresponding XML mapping files, based on the database table structure.

advantages:

1. Improve development efficiency: MyBatis Generator can automatically generate code based on the database table structure, reducing the workload of manually writing repetitive and tedious code, and improving development efficiency.
2. Code Consistency: The generated code is automatically created based on the database table structure, ensuring consistency between the code and the database tables while reducing the risk of errors that may arise from manual coding.
3. Easy to maintain: When there is a change in the database table structure, simply regenerate the code without the need for manual modifications, reducing the amount of maintenance work.

Disadvantages:

1. The quality of generated code is limited: MyBatis Generator can only generate simple persistence layer code based on database table structure, and manual coding is still required for complex logic processing. The generated code usually only consists of basic CRUD operations and cannot meet complex business requirements.
2. Configurations are complex: using MyBatis Generator requires writing XML configuration files with many configuration options, which may present a learning curve for beginners due to the need to grasp certain configuration knowledge.
3. Not all databases are supported: MyBatis Generator only supports certain databases, and may not fully support or even support at all some non-mainstream databases.

Overall, MyBatis Generator has advantages in improving development efficiency and code consistency, but it also has limitations in terms of code quality and configuration complexity. When deciding whether to use MyBatis Generator, it is important to consider the project requirements and the team’s technical level.
