SpringCloud总结

什么是Spring cloud 　　 构建分布式系统不需要复杂和容易出错。Spring Cloud 为最常见的分布式系统模式提供了一种简单且易于接受的编程模型，帮助开发人员构建有弹性的、可靠的、协调的应用程序。Spring Cloud 构建于 Spring Boot 之上，使得开发者很容易入手并快速应用于生产中。 我所理解的 Spring Cloud 就是微服务系统架构的一站式解决方案，在平时我们构建微服务的过程中需要做如 服务发现注册 、 配置中心 、 消息总线 、 负载均衡 、 断路器 、 数据监控 等操作，而 Spring Cloud 为我们提供了一套简易的编程模型，使我们能在 Spring Boot 的基础上轻松地实现微服务项目的构建。 Spring Cloud 的版本 Spring Cloud 的版本号并不是我们通常见的数字版本号，而是一些很奇怪的单词。这些单词均为英国伦敦地铁站的站名。同时根据字母表的顺序来对应版本时间顺序，比如：最早 的 Release 版本 Angel，第二个 Release 版本 Brixton（英国地名），然后是 Camden、 Dalston、Edgware、Finchley、Greenwich、Hoxton。 Spring Cloud 的服务发现框架——Eureka Eureka是基于REST（代表性状态转移）的服务

New to Spring and Jackson 2. What does this bean declaration allow for in a Spring MVC application?

由 你。 提交于 2019-12-11 16:49:55
问题 I have inherited a spring MVC project that basically has several controllers. I came across a declaration in an xml file.
