私の問題についてはここでたくさん見つけましたが、どれもうまくいきませんでした。 私はこれを説明しましょう。私は、電子メール、件名、テキストのようなデータを取得し、私の電子メールに送信するビューを作成しようとします。'org.springframework.mail.javamail.JavaMailSender'の適格なBeanがありません - Spring MVC
@Authowired to public JavaMailSender mailSender;私は "org.springframework.mail.javamail.JavaMailSender 'というタイプの修飾Beanはありません。そのため、@Beanを@Configに追加する必要がありますが、applicationMailSender.xmlについてはどうしたらいいですか？context：component-注釈を削除した後に をスキャンすると、NullPointerExceptionが発生します。
DBにこのデータをすべて保存した方法を作成する前に、これはうまくいきましたが、このメールで@に電子メールを送信すると何が間違っているのか理解できません。 *私はSpringBootを使用していません ありがとうございました！
MyController：
@Controller
public class ContactController {
@Autowired
private ContactService contactService;
@ModelAttribute("contactUs") //contactUs <form:form commandName="contactUs"
public Contact construct() {
return new Contact();
}
@RequestMapping("/contact")
public String contact() {
return "contact";
}
@RequestMapping(value = "/contact", method = RequestMethod.POST)
public String saveThis(@ModelAttribute("contactUs") Contact contact) {
contactService.saveThis(contact);
contactService.sendSimpleMessage(contact.getEmail().toString(), contact.getSubject().toString(),
contact.getText().toString());
return "contact";
}
}
ContactService：
public interface ContactService {
public void saveThis(Contact contact);
public void sendSimpleMessage(String email, String subject, String text);
}
クラスContactService実装：として
@Service
public class ImplContactService implements ContactService {
@Autowired
private ContactRepository contactRepository;
@Autowired
public JavaMailSender mailSender;
public void saveThis(Contact contact) {
contactRepository.save(contact);
}
public void sendSimpleMessage(String email, String subject, String text) {
SimpleMailMessage message = new SimpleMailMessage();
message.setTo(email);
message.setSubject(subject);
message.setText(text);
mailSender.send(message);
}
}
WEB-INF /コンテキストに配置されConfMailSender.xml、（同じDispatcherServlet）：
<context:component-scan base-package="pl.ourweb" />
<bean id="mailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl">
<property name="host" value="smtp.gmail.com" />
