What is the difference between ibatis and mybatis

The difference between ibatis and mybatis: 1. Different basic information; 2. Different development time; 3. Function and ease of use; 4. Configuration file; 5. Input parameter type and output parameter type; 6. Return Result set acceptance method; 7. Syntax differences; 8. Database dialect support; 9. Plug-in support; 10. Community activity; 11. Globalization support. Detailed introduction: 1. The basic information is different. iBatis provides a persistence layer framework, including SQL Maps and Data Access Objects, etc.

The operating system for this tutorial: Windows 10 system, DELL G3 computer.

iBatis and MyBatis are both persistence layer frameworks used to simplify database access operations, but there are some differences between them. The following is a detailed answer about the difference between iBatis and MyBatis:

1. The basic information is different:

• iBatis provides a persistence layer framework, including SQL Maps and Data Access Objects (DAO), and has a JPetStore instance as its implementation.
• MyBatis is an excellent persistence layer framework that supports customized SQL, stored procedures and advanced mapping, avoiding almost all JDBC code and manual setting of parameters and obtaining result sets. MyBatis can use simple XML or annotations to configure and map native information, mapping interfaces and Java POJOs (Plain Ordinary Java Objects, ordinary Java objects) into records in the database.

2. Different development times:

• The word iBatis comes from the combination of "internet" and "abatis", and is a software developed by Clinton Begin An open source project launched in 2001.
• MyBatis was originally a branch of iBatis, which was migrated to Google Code by the Apache Software Foundation in 2010 and to Github in 2013.

3. Function and ease of use:

• MyBatis provides more powerful functions without losing its ease of use. On the contrary, it is simplified in many places with the help of JDK's generics and annotation features.

4. Configuration file:

• iBatis’ configuration file is usually named sqlMapConfig.xml.
• The configuration file of MyBatis is named Configuration.xml.

5. Input parameter type and output parameter type:

• The input parameter type of elements in iBatis is parameterClass.
• The input parameter type of elements in MyBatis is parameterType.
• The parameter type (return result type) of elements in iBatis is resultClasss.
• The output parameter (return result type) type of the element in MyBatis is resultType.

6. Return result set acceptance method: In iBatis, the result set is returned to class; in MyBatis, the method of returning the result set is different.

7. Syntax differences: iBatis and MyBatis also have subtle syntax differences when writing SQL statements. For example, the tag is required to include other SQL statements in iBatis, but not in MyBatis. In addition, MyBatis also provides richer dynamic SQL functions, such as , , , , , , and Tags such as make it more flexible and convenient to build dynamic SQL queries.

8. Database dialect support: MyBatis supports more database dialects and can better adapt to different database systems, while iBatis is relatively limited.

9. Plug-in support: MyBatis has richer plug-in support, which can easily expand its functions.

10. Community activity: Because MyBatis appeared later, its community activity is higher than iBatis. This makes MyBatis potentially more advantageous in terms of updates and maintenance.

11. Globalization support: iBatis supports internationalization and localization, which can better adapt to the needs of multi-language environments. MyBatis has relatively little support in this regard.

To sum up, iBatis and MyBatis have some differences in functions, syntax, configuration and usage. Choosing which framework to use depends on specific project needs and personal preference. However, overall, due to the increasing community activity and functionality of MyBatis, more and more people choose to use MyBatis as the persistence layer framework.
