通过HTTPS进行REST风格的Web服务

问题描述：

我已通过让我们的加密扩展在Plesk中为我的域安装了SSL证书。 HTTPS的默认端口是。它工作正常。通过HTTPS进行REST风格的Web服务

现在我想在Tomcat 7安装证书，我跟着这个答案https://community.letsencrypt.org/t/how-to-use-the-certificate-for-tomcat/3677/2创建JKS密钥库（从Plesk中使用的相同咱们加密证书）和端口不同的端口上配置Tomcat的连接器。 当我在浏览器（https://mywebsite.com:445）上打开tomcat页面时，该页面是安全的。

问题是，当我尝试用下面的Java客户端

public static void main(String[] args) { 

    try { 

    URL url = new URL("https://mywebsite.com:445"); 
    HttpsURLConnection conn = (HttpsURLConnection) url.openConnection(); 
    conn.setRequestMethod("GET"); 
    conn.setRequestProperty("Accept", "text/plain"); 

    if (conn.getResponseCode() != 200) { 
     throw new RuntimeException("Failed : HTTP error code : " 
       + conn.getResponseCode()); 
    } 

    BufferedReader br = new BufferedReader(new InputStreamReader(
     (conn.getInputStream()))); 

    String output; 
    System.out.println("Output from Server .... \n"); 
    while ((output = br.readLine()) != null) { 
     System.out.println(output); 
    } 

    conn.disconnect(); 

    } catch (MalformedURLException e) { 

    e.printStackTrace(); 

    } catch (IOException e) { 

    e.printStackTrace(); 

    } 

}

结果是一个例外，连接到它（但如果我尝试（https://mywebsite.com:443）它的工作原理）

我需要通过HTTPS访问我的RESTful Web服务的资源。 请帮帮我。 在此先感谢。

备份您的CACERT从JAVA_HOME：

$cp $JAVA_HOME/jre/lib/security/cacerts $JAVA_HOME/jre/lib/security/jssecacerts

然后从服务中导入证书。

$keytool -import -trustcacerts -keystore $JAVA_HOME/jre/lib/security/jssecacerts -storepass 
changeit -noprompt -alias {cert alias} -file {cert file}

然后重新启动您的应用程序。

非常感谢......它的作品......最后一个问题：如果我想使用另一种类型的客户端（如Android，IOS，智能设备），我应该先导入我的服务证书吗？ –

是的，我认为SSL证书是一个自签名的，这就是你得到PKIX错误，当你导入证书，Java检查作为受信任的证书。 – AndresMontj

答

Java没有所需的证书。

默认情况下，Java附带了可以信任的证书列表。它在JAVA_HOME/jre/lib/security/cacerts文件中可用。

就你而言，由于这是一个新的/自签名证书，因此你需要告诉Java它可以被信任。你可以这样做，通过添加证书到cacerts文件：

keytool -import -trustcacerts -alias <unique alias name>-file <certificate file path> -keystore <cacerts file path>
