What are the advantages and disadvantages of mybatis reverse engineering?

The advantages of mybatis reverse engineering: 1. Improve development efficiency; 2. Reduce the probability of errors; 3. Simplify code management; 4. Support multiple databases. Disadvantages of mybatis reverse engineering: 1. Reliance on database table structure; 2. Lack of flexibility; 3. Steep learning curve; 4. Not supporting all functions; 5. Unable to generate complex business logic code; 6. Not easy to integrate with other tools or Framework; 7. Not easy to debug and test. In actual use, developers need to evaluate whether to use MyBatis reverse engineering based on project requirements and team technology stack.

MyBatis reverse engineering is a tool that automatically generates MyBatis related code based on the database table structure. It can help developers quickly generate basic CRUD code, thereby accelerating the development process. However, like any tool, MyBatis reverse engineering has its pros and cons.

1. Advantages:

1. Improve development efficiency: MyBatis reverse engineering can automatically generate MyBatis’ Mapper interface and XML based on the database table structure Configuration file, and corresponding POJO class. This greatly reduces the workload of manually writing these basic codes, thereby improving development efficiency.

2. Reduce the probability of errors: Because the code is automatically generated, the correctness of basic CRUD operations can be ensured. At the same time, since the workload of manually writing code is reduced, problems caused by human errors are also reduced.

3. Simplified code management: The automatically generated code is based on the database table structure, which makes the code consistent with the database structure, thus simplifying code management and maintenance work.

4. Support multiple databases: MyBatis reverse engineering usually supports multiple databases, such as MySQL, Oracle, SQL Server, etc. This means developers can easily switch databases without having to modify extensive code.

2. Disadvantages:

1. Dependence on database table structure: The code generated by MyBatis reverse engineering completely depends on the database table structure. If the database table structure changes, the generated code may need to be readjusted. This may increase maintenance costs.

2. Lack of flexibility: Because the code is automatically generated, it may not be able to meet some specific business logic needs. In this case, the developer may need to manually modify the generated code, which may increase the workload.

3. Steep learning curve: For beginners, it may not be easy to get started with MyBatis reverse engineering. In addition, if developers do not have in-depth knowledge of MyBatis and database, they may encounter problems during use.

4. Not all functions are supported: Although MyBatis reverse engineering supports most common database operations, it may not support some special functions or complex queries. In this case, the developer may need to manually write the SQL or adjust the generated code.

5. Unable to generate complex business logic code: MyBatis reverse engineering usually only generates basic CRUD operation code based on the database table structure. For complex business logic codes, such as multi-table related queries, stored procedures, etc., developers still need to write them manually.

6. It is not easy to integrate other tools or frameworks: Since the code generated by MyBatis reverse engineering is based on MyBatis, you may encounter some problems if you need to integrate with other tools or frameworks. . For example, when integrating with Spring Boot, additional configuration or code adjustments may be required.

7. Not easy to debug and test: Automatically generated code may lack comments and documentation, which makes debugging and testing difficult. Additionally, if a problem occurs, developers may need to spend more time locating the problem.

In summary, MyBatis reverse engineering has advantages in improving development efficiency and simplifying code management, but it has shortcomings in relying on database table structure, lack of flexibility, and steep learning curve. In actual use, developers need to evaluate whether to use MyBatis reverse engineering based on project needs and team technology stack, and consider how to maximize its advantages while avoiding or minimizing the impact of its shortcomings.
