This article mainly introduces "Spring RestTemplate as a load balancer client analysis". In daily operation, I believe many people have doubts about Spring RestTemplate as a load balancer client analysis problem. The editor consulted all kinds of materials and sorted out simple and easy-to-use operation methods. I hope it will be helpful to answer the doubts of "Spring RestTemplate as a load balancer client analysis". Next, please follow the editor to study!

RestTemplate can be automatically configured to use the ribbon. To create a load balancing RestTemplate, create RestTemplate @ Bean and use the @ Loadbalanced qualifier.

Warning: RestTemplate bean is no longer created through automatic configuration. It must be created by a single application.

@ Configuration

Public class MyConfiguration {

& nBSP; @ LoadBalanced

@ Bean

RestTemplate restTemplate () {

Return new RestTemplate ()

}

}

Public class MyClass {

@ Autowired

Private RestTemplate restTemplate

Public String doOtherStuff () {

String results = restTemplate.getForObject ("http://stores/stores", String.class)

Return results

}

}

URI requires a virtual hostname (that is, the service name, not the hostname). The Ribbon client is used to create a complete physical address.

Retry failed request

Load balancing RestTemplate can be configured to retry failed requests. By default, this logic is disabled, and you can enable it by adding Spring retries to the application's classpath. The load balancing RestTemplate will conform to some of the Ribbon configuration values associated with the failed retry request. If you want to disable the retry logic using Spring retry in the classpath, you can set spring.cloud.loadbalancer.retry.enabled=false. The properties you can use are client.ribbon.MaxAutoRetries,client.ribbon.MaxAutoRetriesNextServer and client.ribbon.OkToRetryOnAllOperations.

At this point, the study on "Spring RestTemplate as a load balancer client analysis" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it!
