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

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

the above properties must be configured in the bootstrap.properties config section to be loaded correctly. Because the configuration of config will precede application.properties , and bootstrap.properties the load is before application.properties . Create a REST API to return the From property of the configuration center, as follows: Configure @Value("${from}") the From property in the service by binding.Launch the app and access: Http://localhost:7002/from,

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 "Spring Cloud Building Mi

The host location requested here is not in the form of a specific I

Let's explore how the Spring cloud architecture is built and how it can be used in enterprise projects.Source source technical supp
