Spring boot 如何添加胡须电子邮件模板并发送

胡须模板：

email.Mustache

{{subject}}

Hello {{userName}}!

我将发送的对象

{{subject}}

Hello {{userName}}!

data class Email(
        @Email
        val emailAddress: String,
        val subject: String,
        val userName: String,
        val message: String
)

我的服务：

{{subject}}

Hello {{userName}}!

@Service
class EmailService {

    @Autowired
    private lateinit var javaMailSender: JavaMailSender

    override fun sendEmail(email: Email): Boolean {
        val msg = SimpleMailMessage()
        msg.setTo(email.emailAddress)
        msg.setSubject(email.subject)
        msg.setText(email.message)
        try {
            javaMailSender.send(msg)
        } catch (e: Exception) {
            return false
        }
        return true
    }
}

但是我怎样才能在这里加载我的胡子模板呢？我想我需要解析胡须模板，然后使用它作为

msg.setText（parsedTemplate）

——类似的东西。

它看起来可以做你需要的事情：

{{subject}}

Hello {{userName}}!

import com.github.mustachejava.DefaultMustacheFactory
import com.github.mustachejava.Mustache
import java.io.StringWriter

data class Email(
    val subject: String,
    val userName: String
)

fun main() {
    val scopes = mapOf(
        "email" to Email(subject = "Welcome", userName = "J_Strauton")
    )

    val writer = StringWriter()
    val mf = DefaultMustacheFactory()
    val mustache: Mustache = mf.compile("email.mustache")
    mustache.execute(writer, scopes)
    writer.flush()

    val email = writer.toString()
}

您的

email.mustache

文件可能如下所示：

{{subject}}

Hello {{userName}}!

{{email.subject}}

Hello {{email.userName}}!
