Spring Autowired异常（无法自动装配字段..）

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。 当我在RegistrationService删除ActivationMailService时，它可以正常工作。 有人能告诉我，我的代码中有什么问题吗？

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

我在运行应用程序时遇到以下错误：

Answer 1

基于例外情况：

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

看来Spring无法找到注入的bean

@Autowired
JavaMailSenderImpl mailSender;

在SendMail类中。

您确定定义了JavaMailSenderImpl类的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

在自动装配的类中编写@Service（“sendMail”）
