使用java发送邮件时获取异常

我在春季使用一个应用程序，有一个与发送邮件有关的问题。发送邮件时发生异常

“javax.mail.MessaginException:501 5.0.0 HELO需要域地址”

当我研究这个问题时，我们发现，这与发送邮件的机器有关

这是我首先设置邮件属性的方式

<bean id="mailSession" class="javax.mail.Session" factory-method="getInstance">
        <constructor-arg>
            <props>
                <prop key="mail.smtp.auth">${mail.smtp.auth}</prop>
                <prop key="mail.smtp.socketFactory.port">${mail.port}</prop>
                <prop key="mail.smtp.socketFactory.class">${mail.smtp.socketFactory.class}</prop>
                <prop key="mail.smtp.socketFactory.fallback">${mail.smtp.socketFactory.fallback}</prop>
                </prop>
            </props>
        </constructor-arg>
        <constructor-arg ref="smtpAuthenticator" />
    </bean>
    <bean id="smtpAuthenticator" class="com.iris.allofactor.commons.mail.SmtpAuthenticator">
        <property name="logger"><ref bean="logger"/></property> 
        <constructor-arg><value>${mail.username}</value></constructor-arg>
        <constructor-arg><value>${mail.password}</value></constructor-arg>
    </bean>
    <bean id="mailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl">
        <property name="host"><value>${mail.host}</value></property>
        <property name="session" ref="mailSession" />
    </bean> 

${mail.smtp.auth}
${mail.port}
${mail.smtp.socketFactory.class}
${mail.smtp.socketFactory.fallback}
${mail.username}
${mail.password}
${mail.host}

在得到HELO异常后，我添加了另一个peroprty

<prop key="mail.smtp.localhost">${mail.smtp.localhost}

${mail.smtp.localhost}

${mail.smtp.socketFactory.fallback}之后

现在没有例外邮件成功，但我的收件人没有收到邮件。有人能帮我解决这个问题吗

我在加载bean时也遇到了一个异常， 例外的是一些类似这样的东西

问：我在尝试发送消息时收到“MessaginException:501 HELO需要域地址”。
答：SMTP提供程序在SMTP HELO命令中使用InetAddress.getLocalHost（）.getHostName（）的结果。如果该调用未能返回任何数据，则HELO命令中不会发送任何名称。检查JDK和名称服务器配置，确保该调用返回正确的数据。您还可以将“mail.smtp.localhost”属性设置为要用于HELO命令的名称

资料来源：

据我所知，当您的电子邮件服务器查看InetAddress.getLocalHost（）.getHostName（）返回的java web服务器的名称，然后拒绝它时，就会发生这种情况。如果电子邮件服务器无法将dns反向发送到web服务器，或者web服务器提供了一个无意义的名称（如localhost），则可能会拒绝主机名。如果您的Web服务器将自己标识为localhost，请尝试添加JDK属性，如props.put（“mail.smtp.localhost”、“real hostname.com”）

我在运行时遇到了类似的问题，下面是解决问题应该做的事情

当您的计算机启动时，它需要知道一些主机名到IP地址的映射，然后才能引用DNS。此映射保存在/etc/hosts文件中。在没有名称服务器的情况下，系统上的任何网络程序都会查阅此文件以确定与主机名对应的IP地址

似乎您正在应用程序中实现邮件，它试图首先找到本地IP映射以路由TCP/UDP包

只要做：

vi/etc/hosts
现在你可以看到了

27.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4

：：1 localhost localhost.localdomain localhost6 localhost6.localdomain6

修改第一行并将Tomcat2附加到Tomcat2.localadminTomcat2，如下所示

27.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 Tomcat2 Tomcat2.localadminTomcat2

：：1 localhost localhost.localdomain localhost6 localhost6.localdomain6

就这样

问候,，

c3po池正在尝试使用
InetAddress.getLocalHost（）.getAddress（）获取本地地址。这将在无法解析本地主机地址的情况下生成异常。很可能您的计算机主机地址配置错误。请注意，Linux服务器上的/etc/hosts应该正确配置并与/etc/hostname对应
 我今天收到了相同的错误消息。它无法解析“localhost”。向hosts文件/etc/hosts中添加一个简单的地址和服务器名，就可以解决这个问题

127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4 Tomcat2: Tomcat2

yourIP      Tomcat2: Tomcat2 "your hostnamename"

我认为你的xml是无效的。您有一个
标记，但没有打开。@kocko不会导致OP看到的错误。有人知道这个问题吗？有人知道解决方案吗
