Spring 5 Design Patterns

By: Dinesh Rajput

Overview of this book

Design patterns help speed up the development process by offering well tested and proven solutions to common problems. These patterns coupled with the Spring framework offer tremendous improvements in the development process. The book begins with an overview of Spring Framework 5.0 and design patterns. You will understand the Dependency Injection pattern, which is the main principle behind the decoupling process that Spring performs, thus making it easier to manage your code. You will learn how GoF patterns can be used in Application Design. You will then learn to use Proxy patterns in Aspect Oriented Programming and remoting. Moving on, you will understand the JDBC template patterns and their use in abstracting database access. Then, you will be introduced to MVC patterns to build Reactive web applications. Finally, you will move on to more advanced topics such as Reactive streams and Concurrency. At the end of this book, you will be well equipped to develop efficient enterprise applications using Spring 5 with common design patterns

Preface

Enabling the Spring MVC


There are many ways to configure the DispatcherServlet and other web components. There are many features of the Spring MVC framework which are not enabled by default, such as HttpMessageConverter, Support for validating @Controller inputs with @Valid, and so on. So, we can enable these features by using either a Java-based configuration or XML configuration.

To enable the MVC Java config, add the annotation @EnableWebMvc to one of your @Configuration classes, as follows:

 import org.springframework.context.annotation.Configuration; 
    import org.springframework.web.servlet.config.annotation.EnableWebMvc; 
    @Configuration 
    @EnableWebMvc 
    public class SpringMvcConfig { 
    } 

In XML configuration, we can use MVC namespace, there is an <mvc:annotation-driven> element that you can use to enable the annotation-driven Spring MVC.
