How to set custom max connection pool size in @feignclient
configuration in spring ,
@FeignClient(name = "content-cms", configuration = ContentCmsServiceFeignConfig.class)
public interface FeignService {
@RequestMapping(value = "/test/", method = RequestMethod.GET)
String getSample(@RequestParam("token") String token, @RequestParam("cid") String cid,
@RequestParam("ratio") String ratio, @RequestParam("s") String source);
}
You can configure the number of connections within the specific Client
implementation used. Feign has out of the box support Apache Http
, OkHttp
and Ribbon
. When using Spring Cloud Open Feign
, the default client is based on what you have in your classpath.
Here is an example using Apache Http
, you can configure your own CloseableHttpClient
bean with the settings you want.
@Configuration
public class HttpClientConfiguration {
@Bean
public CloseableHttpClient httpClient() {
return HttpClients.custom()
.maxConnectionsPerRoute(200)
.maxConnections(200)
.build()
}
}
If you are using Spring Boot, you can configure any of the feign.httpclient.*
properties as well.
feign:
httpclient:
maxConnections: 200
maxConnectionsPerRoute: 200
