Question

我正在尝试通过简单的JAX-RS客户端（例如：

）访问虚拟REST API，例如https://reqres.in/api/users或https://jsonplaceholder.typicode.com/todos。

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);
    }
}

但是每次我尝试使用HTTPS时，都会得到SSLHandshakeExeption服务器是：无法找到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/

我假设该官方Docker映像正在使用JDK可信证书，还是我必须在自己的server.xml中显式配置它？

Answer 1

Liberty默认情况下不使用JDK的受信任证书。如果要使用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

自从上一篇文章以来，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" />
