Spring Cloud (10): Service Gateway Zuul (routing) "version Finchley" Posted in 2018-04-23 | updated on 2018-05-09 | With the introduction of several core components in Spring Cloud, we can already build a brief microservices architecture, perhaps like this:We implemented service registries and service registration and discovery using the Eureka in spring Cloud Netflix, while service consumption and balanced workloads were realized through the Rib

Spring Cloud Eureka is the Service governance module under the spring Cloud Netflix project. The spring cloud Netflix project is one of Spring cloud's sub-projects, primarily packaged with Netflix's range of open source products, which provides a self-configuring Netflix OSS integration for spring boot applications.

Have to say, Springcloud is indeed very strong, there are pivotal and Netfix is its strong backing and technical output. Finally, we chose t

The microservices provided by Spring Cloud are HTTP-based, so it would be convenient to initiate a microservices call if the resttemplate provided by spring, plus a @loadbalanced annotation provided by the Ribbon, are available at the time of request. And load balancing is also possible. However, if the service provider parameters are more complex, then the use of this method requires splicing URLs or use the form of map, but it is not easy to develop. Spring Cloud Family Bucket provides a compo

introduced a similar asynchronous programming approach through Promise. The Java community has not lagged much behind, and Netflix and Typesafe have provided RxJava and Akka Stream technology, allowing the Java platform to have a framework for reactive programming. In fact, earlier, the NIO framework like Mina and Netty can actually handle high-concurrency server-side development tasks, but such techniques are relatively small tools in the hands of a

In this scenario, data copying between multiple test zookeeper clusters can solve the problem by directly copying the zk data file.However, we recently encountered such a problem that we accidentally deleted the data in a path of a cluster. Because the data is not readable, we cannot choose to copy it. Therefore, this scenario can only be solved by code.I have used two scenarios:1. Accidentally delete the data and copy it from other zookeeper clusters.2. Build a test environment and import part
