Question

在RegistrationService，@Autowired registrationDao和registerCustomer工作正常。但它不能自动连接ActivationMailService。

我没有发现问题。我在ActivationMailService中移除RegistrationService时有效。请问有谁请问我的代码中有什么问题？

我已将项目上传到http://www.mediafire.com/?baum85us0rmmue3

运行应用程序时，我收到以下错误：

管理bean：

}

Answer 1

基于例外：

org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [org.springframework.mail.javamail.JavaMailSenderImpl]

似乎Spring找不到要注入的bean

@Autowired
JavaMailSenderImpl mailSender;

在SendMail课程中。

您确定定义了一个类JavaMailSenderImpl的bean吗？

BTW直接注入实现类（而不是它的接口）有点不寻常。

Answer 2

Service类中的方法应注释@Transactional

Answer 3

在自动装配的课程中写@Service（＆＃34; sendMail＆＃34;）

Spring Autowired异常（无法自动装配字段..）
