1 Overview of Spring bootSpring boot is the middle tier of the developer and spring itself framework, helping developers manage the configuration of the application, providing default processing based on common configurations in real-world development (ie, custom-better configuration), simplifying application development, simplifying application operations, and,

Spring Cloud, as a framework for microservices governance, takes into account almost every aspect of microservices governance and has previously written about spring cloud articles that focus on the use of components, and this share answers both of these questions: Spring Wh

In addition to supporting RABBITMQ's automated configuration, Spring Cloud bus supports Kafka, which is now widely used. In this article, we will build a Kafka local environment and use it to try the support of Spring Cloud Bus for Kafka to realize the function of message bus. Since this article will be modified based on the implementation of the previous rabbit, it is helpful to read the "

Below we create the client that provides the service, and register ourselves with the Service registration center. In this article we mainly introduce the registration and discovery of services, so we may try to provide an interface in the service provider to obtain all the current service information.First, create a basic spring boot app. Named eureka-client , in pom.xml , add the following configuration:

return true, so the filter will take effect for all requests. In practice we can use this function to specify the effective range of the filter.Run: The specific logic of the filter. Here we use Ctx.setsendzuulresponse (false) to make Zuul filter the request, do not route it, and then set its return error code via CTX.SETRESPONSESTATUSCODE (401). Of course, we can also further optimize our return, for example, by Ctx.setresponsebody (body) to return the body content to edit and so on.After impl

general-purpose logic to implement the filtering and interception of the request, such as signature check, permission check, request current limit and so on service gateway.From now on, I will record the process and the essence of the recently developed Springcloud micro-service cloud architecture, and help more friends who are interested in developing the Spring cloud framework, hoping to help more good scholars. Let's explore how the

With the introduction of several core components from the previous spring cloud, we have been able to build a short (imperfect) microservices architecture. As shown in the following example:AltWe implemented service registries and service registration and discovery using the Eureka in spring cloud netflix, while service consumption and balanced workloads across t
