1. Spring IoC容器

     IoC:控制反转

     DI:依赖注入

Spring框架负责控制对象的生命周期和对象间的关系。

IoC使对象只需要关心业务逻辑本身，这些互相依赖的对象的创建和协调等工作交给Spring容器来做。对象如何得到它的协作对象的责任就被反转给Spring了。告诉Spring容器这里需要某个bean，它就会丢个实例过来。

容器中的每个bean都有一个对应的BeanDefinition实例，负责保存bean对象的所有必要信息。如bean 对象的 class 类型、是否是抽象类、构造方法和参数、其它属性等等。

BeanFactory：getBean、containBean、getType、getAliases

BeanDefinitionRegistry：registerBeanDefinition、removeBeanDefinition、getBeanDefinition

DefaultListableBeanFactory实现了BeanFactory和BeanDefinitionRegistry接口，负责bean的注册管理工作。

Spring IoC容器的工作流程主要分为两阶段：启动阶段和实例化阶段。

  • 启动阶段:

     容器启动时会通过一些工具类等加载Configuration MetaData，将其解析后组装成相应的BeanDefinition，然后将保存了bean信息的BeanDefinition注册到BeanDefinitionRegistry。

  • 实例化阶段：

    经过第一阶段，所有 bean 定义都通过 BeanDefinition 的方式注册到 BeanDefinitionRegistry 中，当某个请求通过容器的 getBean 方法请求某个对象&#

Summary A developer-focused guide to writing applications using Spring Boot. You'll learn how to bypass the tedious configuration steps so that you can concentrate on your application's behavior. Purchase of the print book includes a free eBook in PDF, Kindle, and ePub formats from Manning Publications. About the Technology The Spring Framework simplifies enterprise Java development, but it does require lots of tedious configuration work. Spring Boot radically streamlines spinning up a Spring application. You get automatic configuration and a model with established conventions for build-time and runtime dependencies. You also get a handy command-line interface you can use to write scripts in Groovy. Developers who use Spring Boot often say that they can't imagine going back to hand configuring their applications. About the Book Spring Boot in Action is a developer-focused guide to writing applications using Spring Boot. In it, you'll learn how to bypass configuration steps so you can focus on your application's behavior. Spring expert Craig Walls uses interesting and practical examples to teach you both how to use the default settings effectively and how to override and customize Spring Boot for your unique environment. Along the way, you'll pick up insights from Craig's years of Spring development experience. What's Inside Develop Spring apps more efficiently Minimal to no configuration Runtime metrics with the Actuator Covers Spring Boot 1.3 About the Reader Written for readers familiar with the Spring Framework. About the Author Craig Walls is a software developer, author of the popular book Spring in Action, Fourth Edition, and a frequent speaker at conferences.

Summary 180 appendix a spring Boot developer Tools 187 appendix b spring Boot starters 188 appendix c Configuration properties 195 appendix d spring boot dependencies 232 index 243 In the spring of 2014, the Delivery Engineering team at Netflix set out to achieve a lofty goal: enable end-to-end global continuous delivery via a software platform that facilitates both extensibility and resiliency. my team had previously built two different applications attempting to address Netflix's delivery and deployment needs, but both were beginning to show the telltale signs of monolith-ness and neither met the goals of flexibility and resiliency. What's more, the most stymieing effect of these monolithic applications was ultimately that we were unable to keep pace with our partner's inno- vation. Users had begun to move around our tools rather than with them It became apparent that if we wanted to provide real value to the company and rap- idly innovate, we needed to break up the monoliths into small, independent services that could be released at will. Embracing a microservice architecture gave us hope that we could also address the twin goals of flexibility and resiliency. but we needed to do it on a credible foundation where we could count on real concurrency, legitimate moni- toring, reliable and easy service discovery, and great runtime performance With the jVM as our bedrock, we looked for a framework that would give us rapid velocity and steadfast operationalization out of the box. We zeroed in on Spring Boot Spring Boot makes it effortless to create Spring-powered, production-ready ser- vices without a lot of code! Indeed, the fact that a simple Spring Boot Hello World application can fit into a tweet is a radical departure from what the same functionality required on the vm only a few short years ago. Out-of-the-box nonfunctional features like security, metrics, health-checks, embedded servers, and externalized configura tion made boot an easy choice for us FOREWORD Yet, when we embarked on our Spring boot journey solid documentation was hard to come by. Relying on source code isnt the most joyful manner of figuring out how to properly leverage a frameworks features It's not surprising to see the author of mannings venerable Spring in Action take on the challenge of concisely distilling the core aspects of working with Spring Boot into another cogent book. Nor is it surprising that Craig and the Manning crew have done another tremendously wonderful job! Spring Boot in Action is an easily readable book, as weve now come to expect from Craig and manning From chapter Is attention-getting introduction to Boot and the now legend ary 9Oish-character tweetable Boot application to an in-depth analysis of Boots Actuator in chapter 7, which enables a host of auto-magical operational features required for any production application, Spring Boot in Action leaves no stone unturned. Indeed, for me, chapter 7's deep dive into the Actuator answered some of the lingering questions I've had in the back of my head since picking up Boot well over a year ago. Chapter 8s thor- ough examination of deployment options opened my eyes to the simplicity of cloud Foundry for cloud deployments. One of my favorite chapters is chapter 4, where Craig explores the many powerful options for easily testing a Boot application. From the get- o, I was pleasantly surprised with some of Springs testing features, and boot takes g advantage of them nicely As I've publicly stated before, Spring Boot is just the kind of framework the Java community has been seeking for over a decade. Its easy-to-use development features and out-of-the-box operationalization make java development fun again I,m pleased to report that Spring and spring boot are the foundation of Netflix's new continuous delivery platform. What's more, other teams at Netflix are following the same path because they too see the myriad benefits of boot It's with equal parts excitement and passion that I absolutely endorse craigs book as the easy-to-digest and fun-to-read Spring boot documentation the Java community has been waiting for since Boot took the community by storm. Craigs accessible writ- ing style and sweeping analysis of boot's core features and functionality will surely leave readers with a solid grasp of Boot(along with a joyful sense of awe for it) Keep up the great work Craig Manning Publications, and all the brilliant develop ers who have made spring boot what it is today each one of you has ensured a bright future for the JV ANDREW GLOVER MANAGER, DELIVERY ENGINEERING AT NETFLIX preface At the 1964 New York World's Fair, Walt Disney introduced three groundbreaking attractions:"“it' s a small world,”“ Great Moments with mr. Lincoln," and the“ Carouse of Progress " All three of these attractions have since moved into disneyland and walt Disney world, and you can still see them today My favorite of these is the Carousel of Progress. Supposedly, it was one of Walt Disneys favorites too. It's part ride and part stage show where the seating area rotates around a center area featuring four stages. Each stage tells the story of a family at different time periods of the 20th century-the early 1900s, the 1920s the 1940s, and recent times-highlighting the technology advances in that time period The story of innovation is told from a hand-cranked washing machine, to electric lighting and radio, to automatic dishwashers and television, to computers and voice-activated appliances In every act, the father (who is also the narrator of the show)talks about the latest inventions and says "It cant get any better only to discover that in fact, it does get better in the next act as technology progresses Although Spring doesn't have quite as long a history as that displayed in the Car- ousel of Progress, I feel the same way about Spring as"Progress Dad felt about the 20th century. Each and every Spring application seems to make the lives of developers so much better. Just looking at how Spring components are declared and wired together, we can see the following progression over the history of Spring
