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

Passing model data to the view


As of now, we have implemented a very simple HomeCotroller, and tested it. But in the web application, we have also passed model data to the view layer. That model data we passed in the model (in a simple word, it is Map), and that model is returned by the controller along with logical view name. As you already know, Spring MVC supports several return types of the handler method. Let's see the following example:

    package com.packt.patterninspring.chapter10.bankapp.web.controller; 
 
    import java.util.List; 
 
    import org.springframework.beans.factory.annotation.Autowired; 
    import org.springframework.stereotype.Controller; 
    import org.springframework.ui.ModelMap; 
    import org.springframework.web.bind.annotation.GetMapping; 
    import org.springframework.web.bind.annotation.PostMapping; 
 
    import com.packt.patterninspring.chapter10.bankapp.model.Account; 
    import com.packt.patterninspring.chapter10.bankapp.service.AccountService;
