MYBATIS - ENVIRONMENT You would have to set up a proper environment for MyBatis before starting off with the actual development work. This chapter explains how to set up a working environment for MyBatis Unzip the downloaded files to extract .jar files and keep them in appropriate folders/directory. Set CLASSPATH variable for the extracted .jar files appropriately. Database Setup Create an EMPLOYEE and getters } Mapped Statements Mapper XML is an important file in MyBatis, which contains a set of statements to configure various SQL statements such as select, insert, update, and delete. These
