像所有其他客户端一样，如apache httpclient，默认情况下，Jersey会检查SSL证书，这是正确的方法。但在某些情况下，如开发阶段，很可能是我们没有CA可信SSL证书。所以问题是，我们如何让Jersey忽略SSL证书错误？

Answer 1

package com.xxxxxxx.rest;

import java.security.KeyManagementException;
import java.security.NoSuchAlgorithmException;
import java.security.cert.X509Certificate;
import java.util.Properties;

import javax.net.ssl.SSLContext;
import javax.net.ssl.TrustManager;
import javax.net.ssl.X509TrustManager;
import javax.ws.rs.client.Client;
import javax.ws.rs.client.ClientBuilder;

import org.glassfish.jersey.client.JerseyClientBuilder;

public class RestClient {

    private Client client;

    public RestClient(Properties properties) {
        super();
        ClientBuilder clientBuilder = new JerseyClientBuilder();
        SSLContext sslContext = null;
        TrustManager[] trustAllCerts = new X509TrustManager[] { new X509TrustManager() {
            @Override
            public java.security.cert.X509Certificate[] getAcceptedIssuers() {
                return null;
            }

            @Override
            public void checkClientTrusted(X509Certificate[] certs, String authType) {
            }

            @Override
            public void checkServerTrusted(X509Certificate[] certs, String authType) {
            }
        } };
        try {
            sslContext = SSLContext.getInstance("SSL");
            sslContext.init(null, trustAllCerts, null);
        } catch (NoSuchAlgorithmException | KeyManagementException e) {
        }
        clientBuilder.sslContext(sslContext);
        client = clientBuilder.build();
    }

    public <T> T execRequest(String uri, Class<T> type) {
        return client.target(uri).request().get(type);
    }
}

Answer 2

请注意，信任所有证书风险极大 。 做这件事时要小心。

以下内容与yukuan's answer中显示的内容差别不大。但是，以下解决方案仅使用JAX-RS Client API。理论上，它也应该与其他JAX-RS实现一起使用：

TrustManager[] trustManager = new X509TrustManager[] { new X509TrustManager() {

    @Override
    public X509Certificate[] getAcceptedIssuers() {
        return null;
    }

    @Override
    public void checkClientTrusted(X509Certificate[] certs, String authType) {

    }

    @Override
    public void checkServerTrusted(X509Certificate[] certs, String authType) {

    }
}};

SSLContext sslContext = SSLContext.getInstance("SSL");
sslContext.init(null, trustManager, null);

Client client = ClientBuilder.newBuilder().sslContext(sslContext).build();

^{注1：在撰写本文时，上述标准解决方案无法使用RESTEasy。 RESTEasy将来自Apache HttpComponents项目的HTTP调用委托给HttpClient。要使用RESTEasy信任所有证书，必须自定义HttpClient。有关详细信息，请查看此answer。}

^{注2：您可能会发现https://badssl.com是一个有用的资源来测试客户端是否存在错误的SSL配置。}

Answer 3

您可以尝试这样的事情：

    // Create a trust manager that does not validate certificate chains
    TrustManager[] trustAllCerts = new TrustManager[] {new X509TrustManager() {
        public java.security.cert.X509Certificate[] getAcceptedIssuers() { return null; }
        public void checkClientTrusted(X509Certificate[] certs, String authType) { }
        public void checkServerTrusted(X509Certificate[] certs, String authType) { }
    }};

    // Install the all-trusting trust manager
    SSLContext sc;
    try {
        sc = SSLContext.getInstance("SSL");
        sc.init(null, trustAllCerts, new java.security.SecureRandom());
        HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());
    } catch (Exception e) {
        e.printStackTrace();
    }

    // Create all-trusting host name verifier
    HostnameVerifier allHostsValid = new HostnameVerifier() {
        public boolean verify(String hostname, SSLSession session) {
            return true;
        }
    };
    // Install the all-trusting host verifier
    HttpsURLConnection.setDefaultHostnameVerifier(allHostsValid);

Answer 4

不是试图忽略错误，而是首先避免错误。添加代码作为变通方法是有风险的，因为轶事经验表明代码最终将最终投入生产。

出于开发目的，您应该创建一个合适的信任存储区，以便您的开发证书受信任。 this related question的已接受答案记录了如何为此类方案创建此类信任存储。如果你手头有服务器证书，几乎可以肯定，你可以避免浏览器步骤并编写所有脚本。

理想情况下，如果无法找到证书（这样您就不会意外地将开发证书配置部署到生产计算机上），这会成为一个失败的进程。
