为官方 Docker 映像 microProfile3java11 打开 Liberty SSLHandshakeException

Question

我正在尝试使用简单的 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，我都会得到服务器所在的 SSLHandshakeExeption：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/

我假设这个官方 Docker 映像正在使用 JDK 可信证书，还是我必须在自己的 server.xml 中明确配置它？

Answer 1

Liberty 默认不使用 JDK 的可信证书。如果您想使用 cacerts 文件进行信任，则必须对其进行配置。我假设您没有 ssl 配置。要添加 cacerts 文件，您可以添加如下配置：

 <ssl id="defaultSSLConfig" keyStoreRef="defaultKeyStore" trustStoreRef="caTrustStore" />  
<keyStore id="caTrustStore" location=“enter path to cacerts file" type="JKS" password="changeit" />

Answer 2

自上次发布以来，这实际上变得更容易配置。 ssl 元素上有一个属性，它将告诉 SSL 上下文使用 JVM 的默认信任库以及配置的信任库。

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