for service discovery and configuration management using the zookeeper approach.Spring Cloud StreamThe Data flow Operation development package encapsulates the sending and receiving messages with Redis,rabbit, Kafka, and so on.Spring Cloud CLIBased on the Spring Boot CLI, you can quickly set up cloud components on a command-line basis.RibbonProvides load balancing in the cloud with a choice of load balancing strategies to match service discovery and circuit breaker usage.TurbineTurbine is a too

service instance and replaces the actual requested IP address and port with the service name, which completes the invocation of the service interface.After you have finished writing your code, the reader can start Eureka-server, eureka-client, and Eureka-consumer-ribbon. To track how the Eureka-consumer-ribbon service consumes the interface of the Eureka-client service /dc , and can also observe its load balancing effect by initiating multiple eureka-client services.From now on, I will record t

Run (args);} By default, the service registry will also try to register itself as a client, so we need to disable its client registration behavior by simply application.properties adding the following information to the configuration file: 123456 s

Building a Hystrix dashboard in spring cloud is very simple and requires only the following four steps:Create a standard spring boot project named: Hystrix-dashboard.Edit Pom.xml, depending on the content as follows:To apply the main class plus @enablehystrixdashboard, enable the Hystrix dashboard feature.@EnableHystrixDashboard@SpringCloudApplicationpublic class HystrixDashboardApplication {public static void main(String[] args) {SpringApplication.run(HystrixDashboardApplication.class, args);}}

Benefits:Solve the problem of traditional single-block style applications: Single code base, complex code maintenance Single release unit, difficult to test Single release unit, publishing difficulty Very high requirements for server hardware configuration, vertical expansion difficulties Unable to be stateless, horizontal expansion difficult Solve the problem of centralized service management mechanism: A single point of failure may occur Poor scalability, prone to

To configure specific implementations under the Compute-service service. Invoke the computeclient defined above in the Web layer, as follows: @RestController public class Consumercontroller {@Autowired computeclient Compu Teclient; @RequestMapping (Value = "/add", Method = Requestmethod.get) public Integer Add () { retu RN Computeclient.add (20 application.properties do not change, specify the Eureka service registry, such as: spring.application.name=feig

Create a basic spring boot project, named Eureka-server, and introduce the required dependencies in the Pom.xml:Start a service registry with @enableeurekaserver annotations to provide conversations to other apps. This step is very simple, just add this annotation to a normal spring boot application to enable this feature, such as the following example:@EnableEurekaServer@SpringBootApplicationpublic class Application {public static void main(String[] args) {new SpringApplicationBuilder(Applicati
