在的問題，我可以看到你使用的是春天開機，所以只需添加下面的依賴在你的項目

<dependency> 
     <groupId>org.springframework.boot</groupId> 
     <artifactId>spring-boot-starter-mail</artifactId> 
    </dependency>

而且在application.properties添加適當的值到下面的鍵。

下面是添加Gmail作爲您的郵件發件人

spring.mail.host=smtp.gmail.com 
spring.mail.port=465 
spring.mail.protocol=smtps 
spring.mail.username=###@gmail.com 
spring.mail.password=##### 
spring.mail.properties.mail.transport.protocol=smtps 
spring.mail.properties.mail.smtps.auth=true 
spring.mail.properties.mail.smtps.starttls.enable=true 
spring.mail.properties.mail.smtps.timeout=2000

，然後在你的服務類自動裝配JavaMailSender樣品，你可以使用它。

我敢打賭沒有在classpath名爲org.springframework.mail.javamail.JavaMailSenderImp類。確保你只創建現有類的bean。

如果您正在使用Eclipse，可以在.classpath文件驗證這

的.classpath

類路徑指定哪些Java源文件和資源文件在項目由Java考慮並指定如何在項目之外找到類型。 Java構建器將Java 源文件編譯到輸出文件夾中，並將資源複製到中。
