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

() + ":" + serviceInstance.getPort() + "/dc"; System.out.println(url); return restTemplate.getForObject(url, String.class); }}As you can see here, we inject loadbalancerclient and resttemplate, and in the implementation of the/consumer interface, First, a Eureka-client service instance is selected through the Choose function of Loadbalancerclient, which is stored in serviceinstance, and the information in these objects is then spliced out to access/ The detailed address of the D

API Gateway is a very important part of the microservices architecture, there are many different services provided to external use, API gateway can be a unified portal, can also be done on the gateway for protocol conversion, permission control and request statistics and limit flow and other workSpring-cloud encapsulates the open source API gateway implemented by Netflix Zuul, and we can easily launch an in

Brief introductionSpring Cloud provides a platform for deploying microservices, including components that are common in MicroServices: Configuration Center Services, API gateways, circuit breakers, service registration and discovery, distributed traceability, OAuth2, consumer-driven contracts, and more. We don't have to know what each component does, and as the t

Brief introductionIn micro-service, service registration and discovery play a key role in the management of each sub-service subsystem. As the system expands more and more, and the number of systems split into microservices increases correspondingly, the URL to manage and access these microservices becomes tricky, and if we add a micro-service every new one, manually add its URL address or other communicati

Communication between apps follows the publish subscription pattern, which broadcasts data by sharing the subject. This can be seen in, and it shows a typical deployment of a set of interactive spring Cloud stream applications.SCST sensorFigure 6.

Brief introductionSpring Cloud provides a hystrix fault-tolerant library to temporarily invoke an alternate method when the service is unavailable, and a downgrade strategy is implemented for the method that configures the circuit breaker. This article creates a product microservices, registers to the Eureka Service registry, and then we use the Web Client Access /products API to obtain a list of products t

Spring Cloud Bus connects the distributed nodes with a lightweight message broker. It can be used to broadcast configuration file changes or communication between services, and can also be used for monitoring.
