Question

我搜索的时间很长，无法找到答案。

我使用Glassfish并希望通过我们的smtp服务器发送电子邮件。

我已获得服务器的证书：

openssl s_client -connect mail.example.com:587 -starttls smtp > our.cer

我已将cer文件清理为仅包含证书数据我在任何地方都将它导入：

keytool -import -alias mail.example.com -file our.cer -keystore c:\Progra~1\Java\jre7\lib\security\cacerts
keytool -import -alias mail.example.com -file our.cer -keystore c:\Progra~1\Java\JDK17~1.0_4\jre\lib\security\cacerts
keytool -import -alias mail.example.com -file our.cer -keystore c:\PROGRA~1\GLASSF~1.0\GLASSF~1\domains\domain1\config\cacerts.jks

但是我收到以下错误：

javax.mail.MessagingException: Could not convert socket to TLS;
    nested exception is:
        javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
    ...
    Caused by...
    ...
    Caused by...
    ...
    Caused by: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

我的代码段：

...
Properties properties = System.getProperties();
properties.put("mail.smtp.starttls.enable", "true");
properties.put("mail.smtp.host", "mail.example.com");
properties.put("mail.smtp.user", "example@example.com");
properties.put("mail.smtp.password", "some.password");
properties.put("mail.smtp.port", "587"));
properties.put("mail.smtp.auth", "true"));
properties.put("mail.smtp.from", "example@example.com"));
properties.put("mail.transport", "smtp"));

...

Authenticator mailAuthenticator = new Authenticator()
{
    @Override
    protected PasswordAuthentication getPasswordAuthentication()
    {
        return new PasswordAuthentication(properties.getProperty("mail.smtp.user"),
                        properties.getProperty("mail.smtp.password"));
    }
};
try
{
    // Get the default Session object.
    Session session = Session.getDefaultInstance(properties, mailAuthenticator);
    MimeMessage mimeMessage = new MimeMessage(session);
    mimeMessage.setSubject("Hallo world!");
    mimeMessage.setFrom(new InternetAddress(properties.getProperty("mail.smtp.from")));
    mimeMessage.setRecipient(Message.RecipientType.TO, new InternetAddress("example@example.com"));
    mimeMessage.setText("Some text message...");

    Transport transport = session.getTransport(properties.getProperty("mail.transport"));//"smtp"

    int port = Integer.parseInt(properties.getProperty("mail.smtp.port"));//587
    transport.connect(properties.getProperty("mail.smtp.host"),//"mail.example.com"
                    port,
                    properties.getProperty("mail.smtp.user"),//"example@example.com"
                    properties.getProperty("mail.smtp.password"));//Clear text password
    transport.sendMessage(mimeMessage, mimeMessage.getAllRecipients());
    LOG.info("...done sending email");
}
catch (AddressException e)
{
    LOG.log(Level.SEVERE, "Error while sending email", e);
}
catch (MessagingException e)
{
    LOG.log(Level.SEVERE, "Error while sending email", e);
}
catch (Exception e)
{
    LOG.log(Level.SEVERE, "Error while sending email", e);
}

我还尝试Mkyong's suggestion对邮件服务器运行InstallCert (source)但是我得到了：

javax.net.ssl.SSLException: Unrecognized SSL message, plaintext connection?

更新1

我已将证书加载到以下其他位置：

keytool -import -alias mail.example.com -file our.cer -keystore c:\PROGRA~1\GLASSF~1.0\GLASSF~1\domains\domain1\config\keystore.jks
keytool -import -alias mail.example.com -file our.cer -keystore c:\GLASSFISH\config\keystore.jks
keytool -import -alias mail.example.com -file our.cer -keystore c:\GLASSFISH\config\cacerts.jks

我还设置了这些属性：

System.setProperty("javax.net.ssl.keyStore", "c:\\GLASSFISH\\config\\keystore.jks");
System.setProperty("javax.net.ssl.keyStorePassword", "changeit");
System.setProperty("javax.net.ssl.trustStore", "c:\\GLASSFISH\\config\\cacerts.jks");
System.setProperty("javax.net.ssl.trustStorePassword", "changeit");

我还开启了针对ssl（Glassfish控制台，服务器，属性）javax.net.debug=ssl的调试。

它适用于独立的测试应用程序（Java SE），但不适用于Glassfish。

更新2

使用javax.net.debug=ssl并检查注销，我可以看到，即使我已经加载了证书＆＃34;无处不在＆＃34;或者，如果我将Glassfish指向java密钥库，Glassfish将缺少此证书。独立测试应用程序有它：

adding as trusted cert:
    Subject: CN=avast! Web/Mail Shield Root, O=avast! Web/Mail Shield, OU=generated by avast! antivirus for SSL/TLS scanning
    Issuer:  CN=avast! Web/Mail Shield Root, O=avast! Web/Mail Shield, OU=generated by avast! antivirus for SSL/TLS scanning

    Valid from Wed Feb 04 08:56:17 CAT 2015 until Sat Feb 01 08:56:17 CAT 2025

（注意序列号 ...）

似乎是Glassfish缺少的证书;因为独立测试应用程序找到它：

Found trusted certificate:

请帮忙

Answer 1

Okey dokey！我已经弄清楚了。以下是我今天结束的5天旅程的简要介绍......

首先，我从Java密钥库中转储了所有证书，因为它正在使用该密钥库：

keytool -list -v -keystore c:\Progra~1\Java\jre7\lib\security\cacerts > allJavaCerts.txt

然后我从Glassfish密钥库中转储了所有证书，以查看证书是否已正确导入：

keytool -list -v -keystore c:\WORKSP~1\GLASS\config\cacerts.jks > allGFCerts.txt

在Java密钥库列表中，我注意到邮件服务器的证书是由Avast发布的......很奇怪，对吧？

Issuer: CN=avast! Web/Mail Shield Root, O=avast! Web/Mail Shield, OU=generated by avast! antivirus for SSL/TLS scanning

在Java密钥库列表中有Alias name: avastsslscannerroot的证书，但不在Glassfish密钥库列表中 - 谢谢Beyond Compare v3

所以我从Java密钥库导出 avastsslscannerroot 证书并将其导入Glassfish密钥库：

keytool -export -keystore c:\Progra~1\Java\jre7\lib\security\cacerts -alias avastsslscannerroot -file avastsslscannerroot.cer
keytool -import -alias avastsslscannerroot -file avastsslscannerroot.cer -keystore c:\WORKSP~1\GLASS\config\keystore.jks
keytool -import -alias avastsslscannerroot -file avastsslscannerroot.cer -keystore c:\WORKSP~1\GLASS\config\cacerts.jks

现在它有效......

然后它没有在服务器上......经过一些搜索我发现了这个：

mail.smtp.ssl.trust="*"

属性，它适用于我们，因为我们从我们的 Web服务器连接到我们的邮件服务器......

Answer 2

您的本地病毒防护似乎是Avast。

您的问题是由其所谓的 Active Protection Shield 引起的，它拦截SSL流量并扫描其中的恶意内容。为了实现这一目标，Avast必须拦截Java程序和SMTPS服务器之间的通信。有关详细信息，请参阅security.stackexchange.com上的this question 或this question

<强>问题：

由于Avast-Certificate（当然）不受GlassFish信任，并且在安装Avast时未添加到Glassfish，因此无法建立SSL连接

可能的解决方案：

将Avast-Certificate添加到GlassFishs有效证书列表中（这就是提问者所做的事情）
禁用Avast的此功能（设置 - ＆gt; Active Protection - ＆gt;电子邮件保护）

Glassfish，Java电子邮件和证书
