Question

我知道此问题之前会被问到，但我认为这是2 - 3年前，事情发生了变化。现在没有任何代码示例正在运行。我在Java 1.6中尝试以下代码：

Properties props = new Properties();
Security.addProvider(new com.sun.net.ssl.internal.ssl.Provider());
props.setProperty("mail.transport.protocol", "smtp");
props.setProperty("mail.host", "smtp.gmail.com");
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.port", "465");
props.put("mail.debug", "true");
props.put("mail.smtp.socketFactory.port", "465");
props.put("mail.smtp.socketFactory.class","javax.net.ssl.SSLSocketFactory");
props.put("mail.smtp.socketFactory.fallback", "false");
Session session = Session.getDefaultInstance(props, new javax.mail.Authenticator() {
    protected PasswordAuthentication getPasswordAuthentication() {
        return new PasswordAuthentication("uname","password");
    }
});
session.setDebug(true);
Transport transport = session.getTransport();
InternetAddress addressFrom = new InternetAddress("abc@gmail.com");
MimeMessage message = new MimeMessage(session);
message.setSender(addressFrom);

for (int j = 0; j < 20; j++) {
    message.setSubject("Testing javamail plain"+Math.random());
    message.setContent("This is a test", "text/plain");
    String sendTo [] = {"abc@gmail.com"};
    if (sendTo != null) {
        InternetAddress[] addressTo = new InternetAddress[sendTo.length];
        for (int i = 0; i < sendTo.length; i++) {
            addressTo[i] = new InternetAddress(sendTo[i]);
        }
        message.setRecipients(Message.RecipientType.TO, addressTo);
    }
    transport.connect();
    Transport.send(message);
    transport.close();
    System.out.println("DONE");
}

并抛出此异常：

我使用tomcat作为webserver，使用cxf framefork作为webservices。非常感谢任何帮助。

我假设你的类路径中有java.mail jar文件，而cxf支持jar文件。实际上CXF使用Apache Geronimo Javamail /激活实现，所以现在你的应用程序类路径中将有两个不同版本的Sun Javamail库。当你的应用程序试图发送一封电子邮件时，Java会对它应该是哪个版本的库感到困惑使用，并摔倒。所以解决方案可能是删除javamail jar文件或者在pom文件中排除geronimo javamail，如：

<exclusions>          
     <exclusion>               
         <groupId>org.apache.geronimo.specs</groupId>  
         <artifactId>geronimo-javamail_1.4_spec</artifactId>    
     </exclusion>
     <exclusion>  
          <groupId>org.apache.geronimo.specs</groupId>   
          <artifactId>geronimo-activation_1.1_spec</artifactId> 
     </exclusion>

希望这对你有所帮助。

这可能对您有所帮助：如果您使用Maven

，请在pom.xml中添加以下内容

<dependency>
     <groupId>org.apache.cxf</groupId> 
     <artifactId>cxf-rt-core</artifactId> 
     <version>${cxf.version}</version>   
     <exclusions>          
         <exclusion>               
             <groupId>org.apache.geronimo.specs</groupId>  
             <artifactId>geronimo-javamail_1.4_spec</artifactId>    
         </exclusion>
         <exclusion>  
              <groupId>org.apache.geronimo.specs</groupId>   
              <artifactId>geronimo-activation_1.1_spec</artifactId> 
         </exclusion>  
</exclusions>                
</dependency>     
<dependency>    
     <groupId>org.apache.cxf</groupId> 
     <artifactId>cxf-rt-frontend-jaxws</artifactId>     
     <version>${cxf.version}</version>   
</dependency>             
<dependency>   
     <groupId>org.apache.cxf</groupId>  
     <artifactId>cxf-rt-databinding-jaxb</artifactId>    
     <version>${cxf.version}</version>  
     <exclusions>      
          <exclusion>  
               <groupId>org.apache.geronimo.specs</groupId>
               <artifactId>geronimo-javamail_1.4_spec</artifactId>        
          </exclusion>    
          <exclusion>    
               <groupId>org.apache.geronimo.specs</groupId>   
               <artifactId>geronimo-activation_1.1_spec</artifactId>    
          </exclusion>       
     </exclusions>         
</dependency>

然后，添加Sun javamail / activation实现：

<dependency>      
     <groupId>javax.mail</groupId>   
     <artifactId>mail</artifactId>   
     <version>1.4</version>  
</dependency>

Answer 3

您需要实现javax.mail依赖关系。如果您使用的是Maven，请将以下内容添加到pom.xml文件中：

<dependency>
    <groupId>javax.mail</groupId>
    <artifactId>mail</artifactId>
    <version>1.4.4</version>
</dependency>
