java - 针对官方 Docker 镜像 microProfile3java11 打开 Liberty SSLHandshakeException

Question

我正在尝试访问虚拟 REST API，例如 https://reqres.in/api/users或https://jsonplaceholder.typicode.com/todos使用简单的 JAX-RS 客户端，例如:

public class RandomDataProvider {

    private WebTarget webTarget;

    @PostConstruct
    public void setUp() {
        Client client = ClientBuilder.newBuilder()
                .connectTimeout(5, TimeUnit.SECONDS)
                .readTimeout(5, TimeUnit.SECONDS)
                .build();

        this.webTarget = client
                .target("https://reqres.in/api/users");
    }


    public JsonArray getAllPosts() {
        return this.webTarget
                .request()
                .accept(MediaType.APPLICATION_JSON)
                .get(JsonArray.class);
    }
}

但每次我尝试使用 HTTPS 时，我都会收到 SSLHandshakeExeption，服务器是:无法找到请求目标的有效证书路径:

Dockerfile 如下所示:

FROM open-liberty:microProfile3-java11
COPY --chown=1001:0  target/mywar.war /config/dropins/

我假设此官方 Docker 镜像使用 JDK 可信证书，还是我必须在自己的 server.xml 中显式配置它？

自上一篇文章以来，这实际上变得更加容易配置。 ssl 元素上有一个属性，它会告诉 SSL 上下文除了配置信任库之外还使用 JVM 的默认信任库。

<ssl id="defaultSSLConfig" keyStoreRef="defaultKeyStore" trustDefaultCerts="true" />
