引起：sun.security.provider.certpath.SunCertPathBuilderException：无法找到请求目标的有效证书路径

时间：2015-02-14 23:00:54

标签： java email ssl javamail imap

spring mvc app使用JavaMail连接到dovecot / postfix。 spring mvc app和dovecot / postfix安装都在同一个CentOS 7物理服务器盒上运行。该应用程序能够使用JavaMail成功建立imap连接，直到最近，一些用于设置OpenVPN的脚本似乎已经改变了包括SSL配置在内的东西。 如何更改JavaMail代码（或其他配置参数）以使IMAP连接再次起作用？

我目前得到的根错误是：

Caused by: sun.security.provider.certpath.SunCertPathBuilderException:  
unable to find valid certification path to requested target

抛出此错误的代码行是：

store.connect("hostname", "username", "password");

此代码的上下文是：

Properties props = new Properties();
props.setProperty("mail.imap.starttls.enable", "true");
props.setProperty("mail.store.protocol", "imap");
props.setProperty("mail.imap.partialfetch", "false");
String dirStart = "/home/import/xml/xmlimporttest/";
try {
    Session session = Session.getInstance(props, null);
    session.setDebug(true);
    Store store = session.getStore();
    store.connect("hostname", "username", "password");
    Folder inbox = store.getFolder("INBOX");  
    //other stuff
} catch....

完整的堆栈跟踪是：

根据@jCoder的建议，我在运行export JAVA_OPTS=-Djavax.net.debug=all之前键入startup.sh，然后单击应用中触发引发错误的imap登录请求的链接。抛出了与上面相同的堆栈跟踪，但新的调试指令在catalina.out日志中导致了1100多行相关的附加输出。我已将这些附加日志上传到文件共享网站，您可以view the additional logs by clicking on this link。

SSL证书不受Java信任。证书可以是自签名的，也可以由其根证书不在Java证书库中的CA（证书颁发机构）签名。 Java已知的根证书集并不像您的Web浏览器所知道的那样广泛。

假设您确实信任相关证书，可以使用cacerts命令将其添加到Java证书存储区（称为keytool）。例如（根据您的安装和操作系统更改路径）：

keytool -import -trustcacerts -file NewRootCACertificate.crt -keystore "C:\Program Files\Java\jre1.8.0_31\lib\security\cacerts"

默认情况下，cacerts密钥库的密码为changeit。

问题解决了聊天中的工作系统，但没有理想的配置。

  • 看起来以前工作的设置没有使用SSL。
  • 这个设置停止工作，可能是因为软件更新改变了配置（我的猜测）以防止在平原上登录。
  • starttls已启用，以解决无法以明文IMAP模式登录的问题。
  • 缺乏适当信任的证书然后出现问题，因此问题中的错误。
  • 那里的证书（可能是在安装邮件服务器时默认创建的）在公共名称中没有正确的域名，但即使有新证书，并将其添加到似乎是右cacerts密钥库（应用程序日志中提到密钥库路径）客户端无法信任证书。我们从来没有深究过这一点。
  • 使用以下配置达到工作设置（即通过主机名信任服务器并直接使用SSL连接而不是使用starttls）：
    • props.setProperty("mail.imap.ssl.enable", "true");
    • props.setProperty("mail.imap.ssl.trust", "mydomain.com");

这并不理想，但客户端应用程序与IMAP服务器运行在同一台计算机上，因此这可能不是一个巨大的风险。

从长远来看，您可能需要记下您是否已完成此操作，并查看是否可以通过其他方式（可能是自定义证书验证处理程序或显式指定证书存储区）来进行证书验证。

  • 您应该将server：port的证书导入java JRE密钥库，例如以下服务器和端口：

    serverAddress myserver.mydomain.com
serverPort 443
keystore default password did not changed, so it is **changeit** if you changed it use yours as password.

  • 首先，在继续之前检查$ JAVA_HOME和java可执行文件，你应该确定选择正确的JAVA_HOME进行导入，如果你有不同的：

    $ ~/bin$ echo $JAVA_HOME
/opt/jdk
$ ~/bin$ which java
/usr/bin/java
$ ~/bin$ ls -l /usr/bin/java
lrwxrwxrwx 1 root root 22 May 10  2014 /usr/bin/java -> /etc/alternatives/java
$ ~/bin$ ls -l /etc/alternatives/java
lrwxrwxrwx 1 root root 17 Jun  6  2014 /etc/alternatives/java -> /opt/jdk/bin/java
$ ~/bin$ java -version
java version "1.8.0_05"
Java(TM) SE Runtime Environment (build 1.8.0_05-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.5-b02, mixed mode)
$ ~/bin$ `which java` -version
java version "1.8.0_05"
Java(TM) SE Runtime Environment (build 1.8.0_05-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.5-b02, mixed mode)
$ ~/bin$   $JAVA_HOME/bin/java -version
java version "1.8.0_05"
Java(TM) SE Runtime Environment (build 1.8.0_05-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.5-b02, mixed mode)

  • 从服务器提取证书：

    $ openssl s_client -connect <serverAddress:serverPort> 2>&1 < "/" | sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p' > /tmp/myserver.crt

    对于此示例，<serverAddress:serverPort>应替换为myserver.mydomain.com:443

  • 提取的文件应如下所示：

    $ cat /tmp/myserver.crt
-----BEGIN CERTIFICATE-----
blahblahblahaC5jb20wggEiMA0GCSqGSIb3DQEBAQUAA4IBDwAwggEKAoIBAQCd
ME22AKpyBPIRbTwTBedJz/KFtwCAxO2jXIcIob99LXv8W4KMOJgazn2UUBm/azZ1
z+9qhq3UeIy8Z58WK2N5l/SI7s3+bkii/dnpW3Akw8OyXABnN1EyfwnL607POqXm
blahblahblah
  ...Certificate Data is variable for each server address...
blahblahblah
blahblahblahT9p1jar2vxoHv3/dSwKoeLL8XpkmVx9oVUZ3XuICPvEmu8eBfOEm

ME22AKpyBPIRbTwTBedJz/KFtwCAxO2jXIcIob99LXv8W4KMOJgazn2UUBm/azZ1
-----END CERTIFICATE-----

  • 您需要将提取的证书导入JRE密钥库：

    $ keytool -import -alias myserverCert -file  /tmp/myserver.crt -keystore $JAVA_HOME/jre/lib/security/cacerts

  • 导入后，您可以检查java JRE密钥库中是否存在证书：

     $ keytool -list -keystore $JAVA_HOME/jre/lib/security/cacerts

  • java JRE密钥库的默认密码是

    <强>的changeit

  • 要应用更改，您需要重新启动 java JVM。

  • 完成后，如果您在非临时位置创建了临时文件，则可以将其删除：

    $ rm /tmp/myserver.crt

  • 对于您的情况，您可以在VPN建立之前和建立之后一次完成此过程两次，每次只应使用两个别名，如下所示：

    # Before VPN Connect
$ openssl s_client -connect myserver.mydomain.com:443 2>&1 < "/" | sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p' > /tmp/myserver.crt
$ keytool -import -alias myserverCert -file  /tmp/myserver.crt -keystore $JAVA_HOME/jre/lib/security/cacerts
# After VPN Connect
$ openssl s_client -connect myserver.mydomain.com:443 2>&1 < "/" | sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p' > /tmp/myserver-vpn.crt
$ keytool -import -alias myserverVPNCert -file  /tmp/myserver-vpn.crt -keystore $JAVA_HOME/jre/lib/security/cacerts

    如果两个提取的证书相同，则问题是另一个问题，您应该找到另一个解决方案。

    $ diff /tmp/myserver.crt /tmp/myserver-vpn.crt

我希望这可以帮到你
