Spring-boot + mail/Session JNDI 资源 = NoSuchBeanDefinitionException (JavaMailSender)
Spring-boot + mail/Session JNDI resource = NoSuchBeanDefinitionException (JavaMailSender)
我已经为 mail/Session 配置为 JNDI 资源（在 Tomcat 端声明）而苦苦挣扎了几天（没有任何进展），将被拾起通过 spring-boot 应用程序。这个想法是为了避免在应用程序中包含任何关键信息，例如 user/password 数据。
(注意 1：通过 SMTP 的凭据和连接已经过测试，具有应用程序端配置，硬编码在 application.properties 中，因此这不是问题）。
我当前使用的配置如下：
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 我有 spring-boot-starter-mail 依赖（以及其他必要的依赖）。我在其中输入 JavaMailSender bean 的 class 是这个（简化）：
(注意 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、密码后创建 JavaMailSender bean...spring.mail properties（当我设置主机时，后者会起作用，端口，用户名和密码 application.properties)，但是当我使用 jndiName 选项时它会抛出以下堆栈：

我以同样的方式将数据源配置为 JNDI 资源，并且它运行良好。 (mail)Session 是否需要不同的方法，或者我是否遗漏了它的配置？
正如 @m-deinum 在评论中指出的那样，问题不在于配置，而是 spring-boot 1.3.x[= 下的版本缺少 JNDI 支持11=]
为了解决这个问题，我最终听取了@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 类 和新配置并准备就绪！
