to install MyBatis. This chapter discusses how to configure MyBatis using XML file. Since we are communicating with the database, we have to configure the details of the database. Configuration XML is is the file used for the XML-based configuration. By using this file, you can configure various elements. The following programing is a typical structure of MyBatis configuration file. element, we configure the environment of the database that we use in our application. In MyBatis, you can connect to multiple databases by configuring multiple environment elements. To configure the environment
