如何忽略javamail中的服务器证书错误

Question

当我使用 imaps 连接到我的 imap 服务器时，它失败了。

你能告诉我如何忽略 javamail 中的服务器证书错误

还有我的源代码

Properties prop = new Properties();
prop.put("mail.imap.ssl.checkserveridentity", "false");
prop.put("mail.imap.ssl.trust", "*");

Session session = Session.getDefaultInstance(prop);
Store store = session.getStore("imaps");
store.connect("mail.xxx.com", "xxxx", "p@ssw0rd");
System.out.println(store.getFolder("INBOX").getMessageCount());

Answer 1

使用prop.put("mail.imaps.ssl.trust", "*");，因为您使用的是imaps 商店。

对于smtp，您可以尝试： prop.put("mail.smtp.ssl.trust", "*");.

Answer 2

如果您使用的是 javamail 1.4.2+，则可以使用一个套接字工厂来忽略服务器证书。

MailSSLSocketFactory socketFactory= new MailSSLSocketFactory();
socketFactory.setTrustAllHosts(true);
prop.put("mail.imap.ssl.socketFactory", socketFactory);

Answer 3

不要忽略证书验证错误（除非可能在测试环境中）：这违背了使用 SSL/TLS 的意义。

相反，如果您知道您信任该服务器证书，请将其导入您的信任库（例如，JRE 的全局信任库或您使用 javax.net.ssl.trustStore* 系统属性指定的本地信任库）。

Answer 4

     Properties propsSSL = new Properties();
     propsSSL.put("mail.transport.protocol", "smtps");
     propsSSL.put("mail.smtps.host", "hostname");
     propsSSL.put("mail.smtps.auth", "true");
     propsSSL.put("mail.smtps.ssl.checkserveridentity", "false");
     propsSSL.put("mail.smtps.ssl.trust", "*");

以上更改将修复 javax.mail.MessagingException: Could not connect to SMTP host: hostname, port: 465; 的嵌套异常

javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path validation failed: java.security.cert.CertPathValidatorException: Path does not chain with any of the trust anchors
exception 

Answer 5

我也是同样的问题，使用

MailSSLSocketFactory socketFactory= new MailSSLSocketFactory();
socketFactory.setTrustAllHosts(true);
prop.put("mail.pop3s.ssl.socketFactory", socketFactory);

com.sun.mail.util.MailSSLSocketFactory

成功了！！

Answer 6

    Properties pr = new Properties();
    MailSSLSocketFactory socketFactory= new MailSSLSocketFactory();
    socketFactory.setTrustAllHosts(true);
    pr.put("mail.pop3s.ssl.socketFactory", socketFactory);
    Session ses = Session.getInstance(pr);
    ses.setDebug(true);
    URLName url =  new URLName("pop3s://username:password@host:posrt");
    Store store = ses.getStore(url.getProtocol());
    store.connect(url.getHost(), url.getPort(), url.getUsername(), url.getPassword());
    Folder inbox = store.getFolder("INBOX");
    inbox.open(Folder.READ_ONLY);
    try {
        int i = inbox.getMessageCount();
        com.sun.mail.pop3.POP3Message mes;
        while (i > 0) {
            mes = (com.sun.mail.pop3.POP3Message) inbox.getMessage(i);
            System.out.println(mes.getContentID());
            i--;
        }
    } finally {
        inbox.close(false);
        store.close();
    }

这将帮助您绕过证书过程并直接访问 ssl 主机

MailSSLSocketFactory sf = null;
try
{
    sf = new MailSSLSocketFactory();
}
catch (GeneralSecurityException e)
{
    e.printStackTrace();
}
        sf.setTrustAllHosts(true);

Properties pop3Props = new Properties();
pop3Props.setProperty("mail.pop3.ssl.enable", "true");
pop3Props.setProperty("mail.protocol.ssl.trust", "pop3.live.com");
pop3Props.put("mail.pop3s.ssl.socketFactory", sf);
pop3Props.setProperty("mail.pop3s.port", "995");

Session session = Session.getInstance(pop3Props);

try
{
/* Get a Store object*/
   Store store = session.getStore("pop3s");
//process further activity 
}

Answer 8

我认为@Bruno 告诫您不要盲目信任所有具有 hack setTrustAllHosts(true) 的服务器是正确的

在docs at Oracle 中，他们展示了如何将您的开发邮件主机添加到受信任的列表中，而不会迫使您的应用不安全地信任整个世界：

MailSSLSocketFactory sf = new MailSSLSocketFactory();
sf.setTrustedHosts(new String[] { "my-server" });
props.put("mail.smtp.ssl.enable", "true");
// also use following for additional safety
props.put("mail.smtp.ssl.checkserveridentity", "true");
props.put("mail.smtp.ssl.socketFactory", sf);

Answer 9

我也是同样的问题。

MailSSLSocketFactory socketFactory = new MailSSLSocketFactory(); socketFactory.setTrustedHosts(new String[] { "my-server"});

socketFactory.setTrustAllHosts(true); props.put("mail.smtps.socketFactory", socketFactory);

成功了！！

Answer 10

如果是Java 6中仍然存在的问题，那么解决方法很简单。就像Java 7发布一样简单。在机器中安装java 7。java 7具有证书文件，具有忽略证书身份验证的能力。

从以下 java 7 目录复制“cacerts”文件

C:\Program Files\Java\jdk1.7.0_79\jre\lib\security

并粘贴到

C:\Program Files\Java\jdk1.6.0\jre\lib\security

现在证书认证问题将得到解决。
