SpringBoot:具有SSL的FeignClient(p12)

问题描述

我正在尝试为一个使用SSL的外部HTTP API创建FeignClient.难题是-如何使用我的逻辑(在本例中为SSL Connection Factory)修改默认的Spring FeignClient.因此，基本上，我想保留Spring自动为FeignClient做的所有好事情，例如Hystrix，Sleuth跟踪等，并使其与我的SSL工厂一起使用.

I'm trying to create a FeignClient for one external HTTP API which uses SSL.The struggle is - how to modify default Spring FeignClient with my logic, in this case SSL Connection Factory. So basically I wanna keep all the good things Spring automatically does for the FeignClients, like Hystrix, Sleuth tracing, etc and make it work with my SSL factory.

将感谢您的任何建议.

这是我想要做的:

我试图在ComponentScan之外提供自定义@Configuration:

I've tried to provide a custom @Configuration outside of ComponentScan:

@Configuration
public class CustomFeignConfiguration
{
    @Bean
    public Feign.Builder feignBuilder()
    {
        Client trustSSLSockets = new Client.Default(
                TrustingSSLSocketFactory.get("server1"),
                new NoopHostnameVerifier());

        log.info("feignBuilder called");
        return Feign.builder().client(trustSSLSockets);
    }
...
}

让FeignClient通过注释使用

Made FeignClient use it through annotation

    @FeignClient(name = "sslClient", configuration = CustomFeignConfiguration.class, url = "https://...")

在实现"TrustingSSLSocketFactory"的地方类似于此.

Where "TrustingSSLSocketFactory" is implemented similar to this.

现在，如果我将客户端注入Spring应用程序中，则可以看到调用了"feignBuilder"，并且该加载器成功加载了我的密钥.问题在于，创建的客户端实际上并未将指定的SSLFactory用于createSocket调用.所以我得到:

Now if I inject my client in a Spring application, I can see that "feignBuilder" was called and it successfully loaded my keys. The problem is that the created client doesn't actually use the specified SSLFactory for createSocket calls. So I get:

推荐答案

创建Client，因为它是自己的@Bean，而不是构建器的一部分. builder.client(client)稍后会被调用，覆盖您在创建构建器时设置的客户端.

Create the Client as it's own @Bean rather than part of the builder. builder.client(client) gets called later on, overriding the client you set while creating the builder.

所以

@Bean
public Client feignClient()
{
    Client trustSSLSockets = new Client.Default(
            TrustingSSLSocketFactory.get("server1"),
            new NoopHostnameVerifier());

    log.info("feignClient called");
    return trustSSLSockets;
}
