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

be executed sequentially based on the value returned by the method. shouldFilter: Determines whether the filter needs to be executed. Here we return directly 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 ctx.setSendZuulResponse(false) can further optimize our return by making Zuul filter the request, not routing it, and then by ctx.setResponseStatus

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 feat

I. Background Under the microservices architecture, our systems are split into multiple, single-duty microservices based on business. Each service has its own set of APIs to provide to other service calls, so how to ensure security. It is not that you want to invoke the call, we must have the authentication mechanism, is the request from our internal service, we can call our interface. Note that we are tal

Spring Cloud FeignSpring Cloud Feign is a set of declarative service invocation clients based on the Netflix feign implementation. It makes writing Web service clients easier. We only need to configure it by creating an interface and using annotations to complete the binding to the Web service interface. It features pluggable annotation support, including feign annotations, Jax-rs annotations. It also supports pluggable encoders and decoders.

Spring cloud itself provides a lot of components, but we need to follow the business model to customize the enterprise needs of the common architecture, then we need to consider what technology to use now?Below I have made the following technical summary for the spring Cloud Micro-service distributed cloud architecture, hoping to help you:View:H5, Vue.js, Spring

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: S
