org.mybatis.spring.MyBatisSystemException: nested exception is org.apache.ibatis.reflec

Solutions​

org.mybatis.spring.MyBatisSystemException is an exception that may occur when MyBatis is integrated with Spring. The main reason is that problems occur during the configuration or use of MyBatis. The solution to this exception includes the following steps:

Solution​

Confirm the version compatibility of MyBatis and Spring: First confirm whether the versions of MyBatis and Spring used are compatible. You can check the official documentation of MyBatis and Spring or the FAQs for relevant information. Check the MyBatis configuration file : Check whether there are errors or incomplete configurations in the MyBatis configuration file (usually mybatis-config.xml). Pay special attention to checking dataSource, mapperLocations, typeAliases and other configuration items to ensure correct configuration.

Check the Spring configuration file: Check whether the MyBatis-related configuration is correctly introduced in the Spring configuration file, such as mapper scan path, database connection pool and other configurations. Make sure all configurations are correct and complete.

Check the correspondence between the Mapper interface and the Mapper mapping file: Confirm whether the correspondence between the Mapper interface and the Mapper mapping file is correct. The method name in the Mapper interface and the SQL statement id in the Mapper mapping file should correspond one to one.

Check dependencies: Confirm whether the project's dependencies are correctly introduced, especially MyBatis and Spring-related dependencies. You can use build tools such as Maven or Gradle to manage dependencies.
