如何为Gmail配置Spring JavaMailSenderImpl

Question

我正在尝试使用JavaMailSenderImpl类找到用于连接到Gmail SMTP服务器的正确属性.

我先说我尝试过这里的方法.这很好.但是当我尝试使用完全相同的身份验证信息在该帖子下面的配置时,我收到了javax.mail.AuthenticationFailedException.

我目前的配置如下所示.

<bean id="mailSender" class ="org.springframework.mail.javamail.JavaMailSenderImpl" >
    <property name="username" value="XXX@gmail.com" />
    <property name="password" value="XXX" />
    <property name="javaMailProperties">
    <props>
        <prop key="mail.smtp.host">smtp.gmail.com</prop>
        <prop key="mail.smtp.port">587</prop>
        <prop key="mail.smtp.auth">true</prop>
        <prop key="mail.smtp.starttls.enable">true</prop>
    </props>
    </property>
</bean>

如果我知道我的凭据是正确的,为什么我仍然会收到此javax.mail.AuthenticationFailedException.

更新

以下是基于以下答案的更新代码.我仍然收到同样的例外.

<bean id="mailSender" class ="org.springframework.mail.javamail.JavaMailSenderImpl" >
    <property name="username" value="XXX@gmail.com" />
    <property name="password" value="XXX" />
    <property name="javaMailProperties">
    <props>
        <prop key="mail.smtp.from">XXX@gmail.com</prop>
        <prop key="mail.smtp.user">XXX@gmail.com</prop>
        <prop key="mail.smtp.password">XXX</prop>
        <prop key="mail.smtp.host">smtp.gmail.com</prop>
        <prop key="mail.smtp.port">587</prop>
        <prop key="mail.smtp.auth">true</prop>
        <prop key="mail.smtp.starttls.enable">true</prop>
    </props>
    </property>
</bean>

Answer 1

这对我有用:

        <property name="host"><value>smtp.gmail.com</value></property>
        <property name="port"><value>587</value></property>
        <property name="protocol"><value>smtp</value></property>
        <property name="username"><value>${mail.username}</value></property>
        <property name="password"><value>${mail.password}</value></property>
        <property name="javaMailProperties">
            <props>
                <prop key="mail.smtp.auth">true</prop>
                <prop key="mail.smtp.starttls.enable">true</prop>
                <prop key="mail.smtp.quitwait">false</prop>
            </props>
        </property>

对我来说真正的诀窍原来是"协议"值必须是"smtp"(而不是"smtps").

我挣扎了一个小时,找到了正确的设置,使用javamailsender从Gmail发送电子邮件,最后做到了.我发布这个,因为我找不到一个全面的例子来通过gmail发送javamailsender所以希望这会帮助那些想要做同样事情的人:

步骤1:

将以下设置添加到mail.properties:

mail.protocol=smtp
mail.host=smtp.gmail.com
mail.port=465
mail.smtp.socketFactory.port=465
mail.smtp.auth=true
mail.smtp.starttls.enable=true
mail.smtp.debug=true
mail.smtp.starttls.required=true
mail.smtp.socketFactory.fallback=false
mail.from=XXX@gmail.com
mail.username=XXX@gmail.com
mail.password=my_password

然后在你的mailConfiguration类中,@ Value他们:

@Configuration
@PropertySource("classpath:mail.properties")
public class MailConfiguration {

    @Value("${mail.protocol}")
    private String protocol;
    @Value("${mail.host}")
    private String host;
    @Value("${mail.port}")
    private int port;
    @Value("${mail.smtp.socketFactory.port}")
    private int socketPort;
    @Value("${mail.smtp.auth}")
    private boolean auth;
    @Value("${mail.smtp.starttls.enable}")
    private boolean starttls;
    @Value("${mail.smtp.starttls.required}")
    private boolean startlls_required;
    @Value("${mail.smtp.debug}")
    private boolean debug;
    @Value("${mail.smtp.socketFactory.fallback}")
    private boolean fallback;
    @Value("${mail.from}")
    private String from;
    @Value("${mail.username}")
    private String username;
    @Value("${mail.password}")
    private String password;

    @Bean
    public JavaMailSender javaMailSender() {
        JavaMailSenderImpl mailSender = new JavaMailSenderImpl();

        Properties mailProperties = new Properties();
        mailProperties.put("mail.smtp.auth", auth);
        mailProperties.put("mail.smtp.starttls.enable", starttls);
        mailProperties.put("mail.smtp.starttls.required", startlls_required);
        mailProperties.put("mail.smtp.socketFactory.port", socketPort);
        mailProperties.put("mail.smtp.debug", debug);
        mailProperties.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
        mailProperties.put("mail.smtp.socketFactory.fallback", fallback);

        mailSender.setJavaMailProperties(mailProperties);
        mailSender.setHost(host);
        mailSender.setPort(port);
        mailSender.setProtocol(protocol);
        mailSender.setUsername(username);
        mailSender.setPassword(password);
        return mailSender;
    }
}

请注意,我的春节,服务器已启用SSL所以这就是为什么我使用端口465用于SSL端口465如果您正在使用487,你必须使用TLS.

第2步:

点击此链接并选择开启对安全性较低的应用的访问权限.

https://www.google.com/settings/security/lesssecureapps

第3步:

如果您的PC上有AVAST,请将其关闭.AVAST Mail Shield与发送电子邮件冲突.如果您不关闭它,您将收到以下错误:

servlet [dispatcherServlet]的Servlet.service()与path []的上下文引发了异常[请求处理失败; 嵌套异常是org.springframework.mail.MailSendException:邮件服务器连接失败; 嵌套异常是javax.mail.MessagingException:异常读取响应; 嵌套异常是:javax.net.ssl.SSLHandshakeException:sun.security.validator.ValidatorException:PKIX路径构建失败:sun.security.provider.certpath.SunCertPathBuilderException:无法找到请求目标的有效证书路径.

Answer 3

GMail 所需的唯一属性是

<prop key="mail.smtp.starttls.enable">true</prop>

Answer 4

要使Gmail使用TLS或SSL:

TLS/STARTTLS的
端口:用于SSL的587 端口:465

两者都是强制性的参数javax.net.ssl.SSLSocketFactory,mail.smtp.socketFactory.fallback并且mail.smtp.starttls.enable是假的.

<beans>
    <bean id="mailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl">

</beans>

下面的配置（yaml 格式）对我有用

• 我禁用了两因素身份验证https://support.google.com/accounts/answer/1064203?hl=en&ref_topic=7189195
• 我启用了不太安全的应用程序https://www.google.com/settings/security/lesssecureapps

spring.mail:
  host: smtp.gmail.com
  port: 465
  protocol: smtp
  username: xyz@gmail.com
  password: abc
  test-connection: true
  properties:
    "mail.smtp.auth": true
    "mail.smtp.starttls.enable": true
    "mail.smtp.starttls.required": true
    "mail.smtp.socketFactory.class": javax.net.ssl.SSLSocketFactory
    "mail.debug": true

这似乎没有显着不同，但也许可以尝试：

<bean id="mailSender" class ="org.springframework.mail.javamail.JavaMailSenderImpl" >
    <property name="username" value="XXX@gmail.com" />
    <property name="password" value="XXX" />
    <property name="javaMailProperties">
    <props>
        <prop key="mail.smtp.user" value="XXX@gmail.com" />
        <prop key="mail.smtp.password" value="XXX" />
        <prop key="mail.smtp.host">smtp.gmail.com</prop>
        <prop key="mail.smtp.port">587</prop>
        <prop key="mail.smtp.auth">true</prop>
        <prop key="mail.smtp.starttls.enable">true</prop>
    </props>
    </property>
</bean>
