javax.xml.soap.SOAPConnection与java.mail之间的冲突

卢西亚诺

在我们的系统（应用程序）中，我们通过政府服务器托管的网络服务发送税务文件。我们通过以下方法发送此文档：

public SOAPMessage conecta(String xmlNfedados, URL url) throws SOAPException{
    SOAPMessage res = null; 

    try {
        MimeHeaders header = new MimeHeaders();
        header.addHeader("Content-Type", "application/soap+xml");

        MessageFactory factory = MessageFactory.newInstance(SOAPConstants.SOAP_1_2_PROTOCOL);

        SOAPMessage message;
        message = factory.createMessage(header, new ByteArrayInputStream(xmlNfedados.getBytes()));
        SOAPConnection con = SOAPConnectionFactory.newInstance().createConnection();
        res = con.call(message, url);

        con.close();
    } catch (IOException e) {
        e.printStackTrace();
    }
    return res;
}

在此连接之前，我们在jvm中设置以下属性：

public void setPropertiesA1(String caminhoCertificado, String senhaCertificado, String caminhoCacerts){
    //preparar as propriedades
    Properties properties = System.getProperties();
    properties.setProperty("java.protocol.handler.pkgs",  "com.sun.net.ssl.internal.www.protocol");
    properties.setProperty("javax.net.ssl.keyStoreType", "PKCS12");
    properties.setProperty("javax.net.ssl.keyStore", caminhoCertificado);
    properties.setProperty("javax.net.ssl.keyStorePassword", senhaCertificado);
    properties.setProperty("javax.net.ssl.trustStoreType", "JKS");
    properties.setProperty("javax.net.ssl.trustStore", caminhoCacerts);
    properties.setProperty("javax.net.ssl.trustStorePassword", "changeit");
    properties.setProperty("com.sun.xml.ws.transport.http.client.HttpTransportPipe.dump", "true");
    //properties.setProperty("javax.net.debug", "all");

}

一切都很好。直到我们需要发送和接收供应商的电子邮件。在接收电子邮件的情况下，我们使用以下方法：

public static Store conectar(String login, String senha)
throws NoSuchProviderException, MessagingException
{
    logger.info("Conectando ao servidor de e-mail");

    logger.info("--------------Processo de leitura iniciado-----------------");
    String imap = "imaps";
    String host = "pop.gmail.com";
    int porta = 587;
    String diretorioServidor = "Inbox";

    Properties prop = new Properties();
    //System.out.println("numero antes " + System.getProperties().size());
    Session session = Session.getInstance(prop);

    //URLName url = new URLName(imap, host, porta, diretorioServidor, login, senha);

    Store store = session.getStore("pop3s");

    store.connect(host, login, senha);
    //System.out.println("numero depois " + System.getProperties().size());
    logger.info("Conexão estabelecida com servidor IMAP.");
    return store;
}

方法conectar返回的商店对象由以下方法处理：

public static Folder recuperarCaixaEntrada(Store store)
throws MessagingException
{
    Folder folder = store.getFolder("Inbox");
    folder.open(2);

    return folder;
}

稍后在proccessMail（）方法中处理对象文件夹中包含的消息：

public FileInputStream processMail()
throws MessagingException
{
    FileInputStream anexo = null;
    try
    {
      logger.info("Quantida de de e-mails encontrados na caixa de entrada: " + this.messages.length);

     if (this.messages.length <= 0) {
        this.folder.close(true);

        this.store.close();

        System.out.println("esta conectado " + store.isConnected());
        return null;
     }

     System.out.println("Existem na caixa de entrada: " + this.messages.length + " para serem tratados!");

     System.out.println("Tratando e-mail:1 de " + this.messages.length);
     logger.info("Tratando e-mail:1 de " + this.messages.length);

     this.message = this.messages[0];
     System.out.println("Content Type: " + this.message.getContentType());

     if (!this.message.getContentType().equals("text/plain; charset=br-ascii"))
     {
       anexo = getEmail(0);
       System.out.println("Baixou anexo");
     } else {
       System.out.println("Não baixou anexo");
     }

     this.folder.close(true);

     this.store.close();
     } catch (AuthenticationFailedException e) {
       this.store.close();
       logger.error("Falha na Autentica&#65533;&#65533;o: " + e.getMessage());
     } catch (FolderClosedException e) {
       this.store.close();
       logger.error("Falha no fechamento da pasta: " + e.getMessage());
     } catch (FolderNotFoundException e) {
       this.store.close();
       logger.error("Pasta n&#65533;o encontrada: " + e.getMessage());
     } catch (NoSuchProviderException e) {
       this.store.close();
       logger.error("NoSuchProviderException: " + e.getMessage());
     } catch (ReadOnlyFolderException e) {
       this.store.close();
       logger.error("Pasta com permiss&#65533;o de somente leitura: " + e.getMessage());
     } catch (StoreClosedException e) {
       this.store.close();
       logger.error("Erro ao fechar pasta auxiliar: " + e.getMessage());
     } catch (Exception e) {
       this.store.close();
       logger.error("Erro no m&#65533;todo Principal: " + e.getMessage());
       System.out.println(e.getMessage());
    }
  return anexo;
}

因此，在实施了接收电子邮件的过程之后，发送税务文件便开始返回以下错误：

因此，错误消息很明确：无法找到请求的目标的有效证书路径。由于某种原因，我们的应用程序未找到证书路径。但是，如前所述，每次需要发送文档时，都会调用setPropertiesA1（）方法。除此之外，我在应用尝试发送文档之前检查了证书路径是否正常，是否可以。属性“ javax.net.ssl.keyStore”具有正确的值。

如果对这种连接的工作方式有深刻理解的人可以给我们提供解决方案的一瞥，或者指出我们做错了什么地方，那么我们将非常感激。

我希望这个问题足够清楚。

我们使用JBoss AS 7.1.1.Final作为服务器应用程序。

更新这里的问题不仅仅是“缺少证书”，因为如果我们注释负责发送电子邮件的代码，它也将无法工作。

另一个需要说明的地方是，两个连接不是同时完成的，而是一个接一个地发生。更准确地说，是在连接税收文件部分之前先连接电子邮件部分。

这里的主要问题是：在发送或接收电子邮件之后，为什么SOAPConnection无法从属性获取路径？

经过对该问题的广泛研究，我找到了解决方案，该解决方案是结合使用sslcontext来实现密钥管理器和信任管理器。这将在HttpsConnection对象中使用。

重构了方法“ SOAPMessage conecta（String xmlNfedados，URL url）”：

public String conecta(String xmlNfedados, URL url) throws SOAPException{
    String outputString = "";
    try {
        if(context != null){

            URLConnection connection = url.openConnection();
            HttpsURLConnection httpsconn = (HttpsURLConnection) connection;

            httpsconn.setSSLSocketFactory(this.context.getSocketFactory());

            byte[] buffer = new byte[xmlNfedados.length()];
            buffer = xmlNfedados.getBytes();

            ByteArrayOutputStream bout = new ByteArrayOutputStream();
            bout.write(buffer);

            byte[] b = bout.toByteArray();

            httpsconn.setRequestProperty("Content-Type", "application/soap+xml");
            httpsconn.setRequestMethod("POST");

            httpsconn.setDoOutput(true);
            httpsconn.setDoInput(true);

            OutputStream out = httpsconn.getOutputStream();

            out.write(b);
            out.close();

            InputStreamReader isr = new InputStreamReader(httpsconn.getInputStream());

            BufferedReader in = new BufferedReader(isr);

            String responseString = "";

            while((responseString = in.readLine()) != null){
                outputString = outputString + responseString;
            }

            /*MimeHeaders header = new MimeHeaders();
            header.addHeader("Content-Type", "application/soap+xml");

            MessageFactory factory = MessageFactory.newInstance(SOAPConstants.SOAP_1_2_PROTOCOL);

            SOAPMessage message;
            message = factory.createMessage(header, new ByteArrayInputStream(xmlNfedados.getBytes()));
            SOAPConnection con = SOAPConnectionFactory.newInstance().createConnection();
            res = con.call(message, url);*/

        } else {
            throw new IllegalStateException("SSContext não inicializado");
        }

        //con.close();
    } catch (IOException e) {
        e.printStackTrace();
    } 
    return outputString;
}

方法“ getsslContext”负责初始化sslContext：

@Override
public SSLContext getSslContext(String camingoCert, String caminhoCacerts, String senhaCertificado){
    SSLContext sc = null;
    try {
        sc = SSLContext.getInstance("SSL");
        KeyManager[] km = getKeyManager(camingoCert, senhaCertificado);
        TrustManager[] tm = getTrustManager(caminhoCacerts);

        sc.init(km, tm, null);

    } catch (NoSuchAlgorithmException e) {
        e.printStackTrace();
    } catch (KeyManagementException e) {
        e.printStackTrace();
    }
    return sc;
}

以下是“ getKeyManager”：private KeyManager [] getKeyManager（String caminhoCert，String senha）{KeyManagerFactory kmf = null;

    try {
        kmf = KeyManagerFactory.getInstance( KeyManagerFactory.getDefaultAlgorithm() );
        KeyStore ks = KeyStore.getInstance( "pkcs12" );
        ks.load(new FileInputStream( caminhoCert ), senha.toCharArray() );

        kmf.init( ks, senha.toCharArray() );

    } catch (KeyStoreException e) {
        e.printStackTrace();
    } catch (NoSuchAlgorithmException e) {
        e.printStackTrace();
    } catch (CertificateException e) {
        e.printStackTrace();
    } catch (FileNotFoundException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    } catch (UnrecoverableKeyException e) {
        e.printStackTrace();
    }
    return kmf.getKeyManagers();
}

和“ getTrustManager”：

private TrustManager[] getTrustManager(String caminhoCacerts){
    TrustManagerFactory tmf = null;
    try {

        tmf = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm());
        KeyStore ts = KeyStore.getInstance("JKS");
        ts.load(new FileInputStream(caminhoCacerts), SENHACACERTS.toCharArray());
        tmf.init(ts);

    } catch (KeyStoreException e) {
        e.printStackTrace();
    } catch (NoSuchAlgorithmException e) {
        e.printStackTrace();
    } catch (CertificateException e) {
        e.printStackTrace();
    } catch (FileNotFoundException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }
    return tmf.getTrustManagers();
}
