Question

我已经在将邮件/会话配置为JNDI资源（在Tomcat端声明）上进行了几天（并且没有进展）的困难，并被Spring-boot应用程序选中。我们的想法是避免在应用程序中包含任何关键信息，例如用户/密码数据。

（注意1 ：已通过SMTP测试凭据和连接，应用程序端配置在application.properties中进行了硬编码，因此这不是问题。）

我使用的当前配置如下：

server.xml （$ TOMCAT / conf）

<Resource
   name="mail/Session"
   auth="Container"
   type="javax.mail.Session"
   username="user@test.com"
   password="XXX"
   mail.user="user@test.com"
   mail.password="XXX"
   mail.transport.protocol="smtp"
   mail.smtp.host="smtp.test.com"
   mail.smtp.auth="true"
   mail.smtp.port="587"/>

context.xml （webapp / META-INF）

<Context>
    <ResourceLink 
        name="mail/Session"
        global="mail/Session"
        auth="Container"
        type="javax.mail.Session"/>
</Context>

application.properties

spring.mail.jndi-name=java:comp/env/mail/Session

在 pom.xml 中，我有spring-boot-starter-mail依赖项（以及其他必要的依赖项）。我正在使用JavaMailSender bean的类就是这个（简化）：

（注2 ：使用的spring-boot版本是1.2.8.RELEASE）

@Service("emailService")
public class EmailService {

    @Autowired
    public JavaMailSender javaMailSender;

    public void sendSimpleMail(/* ... */) throws MessagingException {

        //Create message
        MimeMessage message = javaMailSender.createMimeMessage();

        MimeMessageHelper helper = new MimeMessageHelper(message);
        helper.setFrom(fromAddress);
        helper.setTo(toAddress);
        helper.setSubject(subject);
        helper.setText(body);

        //Send message
        javaMailSender.send(message);
    }
}

我知道spring-boot自动配置应该在找到jndiName或主机，端口，用户名，密码... spring.mail properties后创建JavaMailSender bean（后者在设置主机，端口，用户名和密码时起作用）在application.properties）中，但是当我使用jndiName选项时它会抛出以下堆栈：

我以相同的方式将dataSource配置为JNDI资源，并且它完美地运行。（邮件）会话是否需要一个不同的方法，或者我错过了它的配置？

Answer 1

正如@m-deinum在评论中指出的那样，问题不在于配置，而是在1.3.x下的spring-boot版本中缺少JNDI支持

为了解决这个问题，我最终注意到 @ m-deinum 的提示并将spring-boot从1.2.8升级到1.3.5 ...处理一些已弃用的问题课程和新配置，随时可用！

Spring-boot + mail / Session JNDI resource = NoSuchBeanDefinitionException（JavaMailSender）
