Preface

For many software systems, saving and retrieving data from a database is a crucial part of the process. In Java land there are many tools and frameworks for implementing the data persistence layer and each of them follow a different approach. MyBatis, a simple yet powerful Java persistence framework, took the approach of eliminating the boilerplate code and leveraging the power of SQL and Java while still providing powerful features.

This MyBatis book will take you through the process of installing, configuring, and using MyBatis. Concepts in every chapter are explained through simple and practical examples with step-by-step instructions.

By the end of the book, you will not only gain theoretical knowledge but also gain hands-on practical understanding and experience on how to use MyBatis in your real projects.

This book can also be used as a reference or to relearn the concepts that have been discussed in each chapter. It has illustrative examples, wherever necessary, to make sure it is easy to follow.

What this book covers

, Getting Started with MyBatis , introduces MyBatis persistence framework and explains the advantages of using MyBatis instead of plain JDBC. We will also look at how to create a project, install MyBatis framework dependencies with and without the Maven build tool, configure, and use MyBatis.

, Bootstrapping MyBatis , covers how to bootstrap MyBatis using XML and Java API-based configuration. We will also learn various MyBatis configuration options such as type aliases, type handlers, global settings, and so on.

, SQL Mappers Using XML , goes in-depth into writing SQL mapped statements using the Mapper XML files. We will learn how to configure simple statements, statements with one-to-one, one-to-many relationships and mapping results using ResultMaps. We will also learn how to build dynamic queries, paginated results, and custom ResultSet handling.
