Ioc Containers in Spring
301AA - Advanced Programming Lecturer: Andrea Corradini [email protected] http://pages.di.unipi.it/corradini/ AP-2018-11: Frameworks and Inversion of Control Frameworks and Inversion of Control • Recap: JavaBeans as Components • Frameworks, Component Frameworks and their features • Frameworks vs IDEs • Inversion of Control and Containers • Frameworks vs Libraries • Decoupling Components • Dependency Injection • IoC Containers in Spring 2 Components: a recap A software component is a unit of composition with contractually specified interfaces and explicit context dependencies only. A software component can be deployed independently and is subject to composition by third party. Clemens Szyperski, ECOOP 1996 • Examples: Java Beans, CLR Assemblies • Contractually specified interfaces: events, methods and properties • Explicit context dependencies: serializable, constructor with no argument • Subject to composition: connection to other beans – Using connection oriented programming (event source and listeners/delegates) 3 Towards Component Frameworks • Software Framework: A collection of common code providing generic functionality that can be selectively overridden or specialized by user code providing specific functionality • Application Framework: A software framework used to implement the standard structure of an application for a specific development environment. • Examples: – GUI Frameworks – Web Frameworks – Concurrency Frameworks 4 Examples of Frameworks Web Application Frameworks GUI Toolkits 5 Examples: General Software Frameworks – .NET – Windows platform. Provides language interoperability – Android SDK – Supports development of apps in Java (but does not use a JVM!) – Cocoa – Apple’s native OO API for macOS. Includes C standard library and the Objective-C runtime. – Eclipse – Cross-platform, easily extensible IDE with plugins 6 Examples: GUI Frameworks • Frameworks for Application with GUI – MFC - Microsoft Foundation Class Library. -
Design Pattern Interview Questions
DDEESSIIGGNN PPAATTTTEERRNN -- IINNTTEERRVVIIEEWW QQUUEESSTTIIOONNSS http://www.tutorialspoint.com/design_pattern/design_pattern_interview_questions.htm Copyright © tutorialspoint.com Dear readers, these Design Pattern Interview Questions have been designed specially to get you acquainted with the nature of questions you may encounter during your interview for the subject of Design Pattern. As per my experience good interviewers hardly plan to ask any particular question during your interview, normally questions start with some basic concept of the subject and later they continue based on further discussion and what you answer: What are Design Patterns? Design patterns represent the best practices used by experienced object-oriented software developers. Design patterns are solutions to general problems that software developers faced during software development. These solutions were obtained by trial and error by numerous software developers over quite a substantial period of time. What is Gang of Four GOF? In 1994, four authors Erich Gamma, Richard Helm, Ralph Johnson and John Vlissides published a book titled Design Patterns - Elements of Reusable Object-Oriented Software which initiated the concept of Design Pattern in Software development. These authors are collectively known as Gang of Four GOF. Name types of Design Patterns? Design patterns can be classified in three categories: Creational, Structural and Behavioral patterns. Creational Patterns - These design patterns provide a way to create objects while hiding the creation logic, rather than instantiating objects directly using new opreator. This gives program more flexibility in deciding which objects need to be created for a given use case. Structural Patterns - These design patterns concern class and object composition. Concept of inheritance is used to compose interfaces and define ways to compose objects to obtain new functionalities. -

For example, if an audio player having support with MP2 files gets problem for MP3 files and having support for MP3 gets problem MP4. So it is a recursive problem. In a software application, for example a recursive problem will be transferring the data across layers. Q. Why Design Patterns? Ans:- Design patterns are used for solving recursive problems in a software application design. A design pattern is a description for how to solve a recursive problem. Design patterns are not a technology or a tool or a language or a platform or a framework. Design patterns are effective proven solutions for recursive problems. Q. How many Design Patterns? Ans:- Actually, there is no fixed count of no of design patterns because design patterns is not a package and not in the form of classes. SUN Microsystems constituted a group with four professional with the name of Gang of Four (GOF) to find effective solutions for the recursive problems. According to GOF, they found 23 design patterns as effective solutions for re-occurring problems. GOF divided java design patterns into 4 categories (a) Creational Design Patterns:- (1) Singleton Pattern. -

A few years ago I had to go out of the country on a business trip, and I didn’t want to risk missing episodes of my favorite show. So, rather than continu- ing to struggle with the timer function on my VCR, I bought a TiVo box. At the time I thought it was simply going to be a much more convenient and reliable way to record programs. -
Implementing Domain-Driven Design
www.EBooksWorld.ir Praise for Implementing Domain-Driven Design “With Implementing Domain-Driven Design, Vaughn has made an important con- tribution not only to the literature of the Domain-Driven Design community, but also to the literature of the broader enterprise application architecture field. In key chap- ters on Architecture and Repositories, for example, Vaughn shows how DDD fits with the expanding array of architecture styles and persistence technologies for enterprise applications—including SOA and REST, NoSQL and data grids—that has emerged in the decade since Eric Evans’ seminal book was first published. And, fittingly, Vaughn illuminates the blocking and tackling of DDD—the implementation of entities, value objects, aggregates, services, events, factories, and repositories—with plentiful exam- ples and valuable insights drawn from decades of practical experience. In a word, I would describe this book as thorough. For software developers of all experience levels looking to improve their results, and design and implement domain-driven enterprise applications consistently with the best current state of professional practice, Imple- menting Domain-Driven Design will impart a treasure trove of knowledge hard won within the DDD and enterprise application architecture communities over the last cou- ple decades.” —Randy Stafford, Architect At-Large, Oracle Coherence Product Development “Domain-Driven Design is a powerful set of thinking tools that can have a profound impact on how effective a team can be at building software-intensive systems. The thing is that many developers got lost at times when applying these thinking tools and really needed more concrete guidance. In this book, Vaughn provides the missing links between theory and practice. -

J2EE Architecture and Patterns in Enterprise Systems
J2EE Architecture and Patterns in Enterprise Systems Zhiguo Guo University of Tampere Department of Computer and Information Science Master’s Thesis May 2004 i University of Tampere Department of Computer and Information Science Zhiguo Guo: J2EE Architecture and Patterns in Enterprise Systems Master’s Thesis, 60 pages May 2004 The purpose of this thesis is to illustrate an enterprise project named HUVA, in which Java Platform 2, Enterprise Edition (J2EE) architecture and patterns are applied. This study took a constructive research approach: It starts from the application domain including the initial plan and business model, then moves to the system architecture covering the architecturally significant requirements and the system structure compliant with J2EE architecture, finally ends at the application design elaborated by applying the J2EE patterns at a high level. As a result the architectural and application design satisfied the project needs and requirements; and the HUVA software has been implemented in practice according to the design. Keywords: J2EE, architecture, pattern, enterprise system. ii Acknowledgements I would like to thank Professor Roope Raisamo and Professor Isto Aho from the University of Tampere for being my encouraging, patient and responsible supervisors during the master’s thesis project. I would like to thank Mr. Mika Miettinen from Solteq Oyj and Mr. Timo Westkämper for supporting the technical aspects of this thesis. Finally, I would like to use this opportunity to express huge thanks to my dear wife, Chongliang Tang for always being the invaluable person behind my success.
