DcClient dcClient; @GetMapping("/consumer") public String dc() { return dcClient.consumer(); }}The way to implement service invocation through spring Cloud feign is much simpler, with the interface defined by @feignclient to unify the life we need to rely on for the MicroServices interface. And in the specific use of the call to the local method a little bit of the call. Since feign is implemented based on the Ribbon, it comes with

A microservices architecture system, the different services will be called each other, such as an order service needs to fetch user data, you need to invoke user services, there are multiple User Service instances, Eureka load balanced to one of the service instances, and the previous chapter, We first use the Java version of the service discovery and invocation service to do examples and porting to the. NET Core version. 　　Version 1.Java Service call

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

This section describes the following service management, and other features that will be introduced in the next few articlesService ManagementFor the service we need to manage the following actionsService machine: For the service deployment of the machine, we need the platform for management monitoring, if an exception occurs, through the API gateway to alarmMetadata: Through metadata we can find annotations of related services, such as name, own

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

in the Agile development , we did find a framework that would enable domain experts, architects, to work together to design an adaptable ROA architecture. But I think we should think of it from another angle. ...even domain experts and architects can work together in a team, but after all, domain experts and architects are people, not gods. So, in the end, how much of the future needs change can be predicted from the current version ? This is really a question that cannot be answered. So, in pr

This is a creation in Article, where the information may have evolved or changed. 1. Overview There is a scenario where a request will be processed by multiple services after the microservices split, and it will be difficult to troubleshoot if a service fails on the requested link.We may need to take the requested service, look at the log for analysis, and when the service has dozens of hundred instances, this is certainly scary. Therefore, in order t
