"Spring Microservices in Action 是一本由John Carnell撰写的书籍,由Manning出版社出版。本书深入探讨了如何使用Spring框架构建微服务应用。通过本书,读者可以了解到Spring在微服务架构中的实际应用和最佳实践。" 在Spring微服务领域,"Spring Microservices in Action"是一本权威指南,它涵盖了Spring生态系统中用于构建微服务的关键技术。Spring框架以其模块化、灵活性和广泛的功能集,在微服务架构中扮演着核心角色。以下是对标题和描述中涉及知识点的详细解释: 1. **Spring框架**:Spring是Java平台上的一个开源应用程序框架,它提供了全面的基础设施支持,包括依赖注入、面向切面编程、数据访问、事务管理等,这些特性使得开发微服务变得更加容易。 2. **微服务架构**:微服务是一种软件开发方法,将大型复杂应用分解为一组小型、独立的服务,每个服务都可以在其自身的进程中运行,与其它服务通过轻量级通信机制(如HTTP RESTful API)进行交互。Spring框架提供工具和库来支持微服务间的通信和治理。 3. **Spring Boot**:作为Spring生态的一部分,Spring Boot简化了Spring应用的初始设置,提供了一种快速构建独立运行的应用程序的方式,特别适合微服务场景。 4. **Spring Cloud**:Spring Cloud是一系列工具的集合,用于快速配置和管理微服务,包括服务发现、配置中心、负载均衡、熔断器、智能路由等,这些工具使得微服务架构的实施更加标准化和便捷。 5. **容器化和Docker**:由于微服务的特性,它们通常被部署在容器中,Spring Microservices in Action可能也会涵盖如何使用Docker进行服务打包和部署。 6. **持续集成/持续部署(CI/CD)**:在微服务环境中,CI/CD是关键流程,Spring框架与Jenkins、Git等工具的集成可以帮助实现自动化构建和部署。 7. **服务治理**:包括服务注册与发现、熔断机制(如Hystrix)、负载均衡(如Ribbon)等,这些都是Spring Microservices in Action可能会详细讨论的主题。 8. **安全与授权**:Spring Security可以帮助保护微服务应用,实现身份验证和授权,确保服务之间的安全通信。 9. **监控与日志**:书中可能会介绍如何使用Spring Actuator等工具对微服务进行性能监控和故障排查,以及日志管理和分析。 10. **测试策略**:对于微服务,单元测试、集成测试和端到端测试的策略尤为重要,Spring框架提供了测试支持,便于编写可维护的测试代码。 通过对这些知识点的学习,读者可以掌握构建、部署和管理微服务应用的全套技能,从而在实践中提升软件开发效率和系统稳定性。

Book Description Build a microservices architecture with Spring Boot, by evolving an application from a small monolith to an event-driven architecture composed of several services. This book follows an incremental approach to teach microservice structure, test-driven development, Eureka, Ribbon, Zuul, and end-to-end tests with Cucumber. Author Moises Macero follows a very pragmatic approach to explain the benefits of using this type of software architecture, instead of keeping you distracted with theoretical concepts. He covers some of the state-of-the-art techniques in computer programming, from a practical point of view. You'll focus on what's important, starting with the minimum viable product but keeping the flexibility to evolve it. What You'll Learn Build microservices with Spring Boot Use event-driven architecture and messaging with RabbitMQ Create RESTful services with Spring Master service discovery with Eureka and load balancing with Ribbon Route requests with Zuul as your API gateway Write end-to-end rest tests for an event-driven architecture using Cucumber Carry out continuous integration and deployment Who This Book Is For Those with at least some prior experience with Java programming. Some prior exposure to Spring Boot recommended but not required. Table of Contents Chapter 1: Introduction Chapter 2: The Basic Spring Boot Application Chapter 3: A Real Three-Tier Spring Boot Application Chapter 4: Starting with Microservices Chapter 5: The Microservices Journey Through Tools Chapter 6: Testing the Distributed System Appendix A: Upgrading to Spring Boot 2.0

Spring Microservices in Action consists of 10 chapters and two appendixes: Chapter 1 introduces you to why the microservices architecture is an important and relevant approach to building applications, especially cloud-based applications. Chapter 2 walks you through how to build your first REST-based microservice using Spring Boot. This chapter will guide you in how to look at your microser- vices through the eyes of an architect, an application engineer, and a DevOps engineer. Chapter 3 introduces you to how to manage the configuration of your microser- vices using Spring Cloud Config. Spring Cloud Config helps you guarantee that your service’s configuration information is centralized in a single repository, versioned and repeatable across all instances of your services. Chapter 4 introduces you to one of the first microservice routing patterns: ser- vice discovery. In this chapter, you’ll learn how to use Spring Cloud and Net- flix’s Eureka service to abstract away the location of your services from the clients consuming them. Chapter 5 is all about protecting the consumers of your microservices when one or more microservice instances is down or in a degraded state. This chapter will demonstrate how to use Spring Cloud and Netflix Hystrix (and Netflix Ribbon) to implement client-side load balancing of calls, the circuit breaker pattern, the fallback pattern, and the bulkhead pattern. Chapter 6 covers the microservice routing pattern: the service gateway. Using Spring Cloud with Netflix’s Zuul server, you’ll build a single entry point for all microservices to be called through. We’ll discuss how to use Zuul’s filter API to build policies that can be enforced against all services flowing through the ser- vice gateway. Chapter 7 covers how to implement service authentication and authorization using Spring Cloud security and OAuth2. We’ll cover the basics of setting up an OAuth2 service to protect your services and also how to use JavaScript Web Tokens (JWT) in your OAuth2 implementation. Chapter 8 looks at how you can introduce asynchronous messaging into your microservices using Spring Cloud Stream and Apache Kafka. Chapter 9 shows how to implement common logging patterns such as log corre- lation, log aggregation, and tracing using Spring Cloud Sleuth and Open Zipkin. Chapter 10 is the cornerstone project for the book. You’ll take the services you’ve built in the book and deploy them to Amazon Elastic Container Service (ECS). We’ll also discuss how to automate the build and deployment of your microservices using tools such as Travis CI. Appendix A covers how to set up your desktop development environment so that you can run all the code examples in this book. This appendix covers how the local build process works and also how to start up Docker locally if you want to run the code examples locally. Appendix B is supplemental material on OAuth2. OAuth2 is an extremely flexi- ble authentication model, and this chapter provides a brief overview of the dif- ferent manners in which OAuth2 can be used to protect an application and its corresponding microservices.
