Fegin的单客户端配置类配置

Fegin 单客户端配置类方式设置配置

个人所知的这种方式可以配置的属性为: encoder , decoder, Contract , Logger , Retryer , ErrorDecoder , Request.Options , RequestInterceptor

其中重点是: @FeignClient(name = "stores", configuration = FooConfiguration.class) ,
也可以使用增加方式: FooConfiguration只配置需要的配置
@FeignClient(value = "stores", configuration = {FooConfiguration.class,DefaultEncoder.class, DefaultDecoder.class})
1
并且FooConfiguration配置类上, 无需标明@Configuration, 标明后就是全局配置了!

个人例子, 设置单个客户端读取超时
fegin接口

@FeignClient(value = "account-service-api", url = "${account-service.url}", path = "/accountActiveInfo",
        configuration = AccountFeignRequest.class) // 使用自定义组合配置类
public interface AccountActiveInfoApi  {

    /**
     * 查询不活跃用户
     *
     * @param accountQueryRqt
     * @author: ZhiHao
     * @date: 2022/5/25
     */
    @PostMapping("/inactiveQuery")
    AccountActiveInfoRsp<AccountRsp> inactiveQuery(@RequestBody InactiveQueryRqt accountQueryRqt);
}

AccountFeignRequest 配置类

注意无需配置@Configuration 注解, 配置后是会到 父Bean工厂上下文中

public class AccountFeignRequest {

    @Bean
    public Request.Options feignRequestOptions() {
        return new Request.Options(10000,333*1000);
    }

    @Bean
    public Encoder defaultEncoder() {
        return new DefaultEncoder();
    }

    @Bean
    public Decoder defaultDecoder() {
        return new DefaultDecoder();
    }

    @Bean
    public ErrorDecoder defaultErrorDecode() {
        return new DefaultErrorDecode();
    }
}

结果:
