フィールドをautowireできませんでした：private org.springframework.mail.javamail.JavaMailSender [Spring 4.0.0 REALEASE]

Question

私のアプリケーションでHTMLメール送信者を作成しようとしましたが、このエラーが発生しました。

<?xml version="1.0" encoding="UTF-8"?> 
<beans xmlns="http://www.springframework.org/schema/beans" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" 
    xsi:schemaLocation="http://www.springframework.org/schema/beans 
    http://www.springframework.org/schema/beans/spring-beans.xsd 
    http://www.springframework.org/schema/context 
    http://www.springframework.org/schema/context/spring-context.xsd"> 

    <context:property-placeholder location="classpath*:/mail_server.properties" /> 
    <bean id="mailSender" class="org.springframework.mail.javamail.JavaMailSender"> 
     <property name="host" value="${host}"/> 
     <property name="port" value="${port}"/> 
     <property name="username" value="${username}"/> 
     <property name="password" value="${password}"/> 
     <property name="javaMailProperties"> 
      <props> 
       <prop key="mail.transport.protocol">smtp</prop> 
       <prop key="mail.smtp.auth">true</prop> 
       <prop key="mail.smtp.starttls.enable">true</prop> 
       <prop key="mail.debug">true</prop> 
      </props> 
     </property> 
    </bean> 
</beans> 

次に、私はそれをSpringプロジェクトのapplicationContext.xmlファイルにインポートしました。 Javaクラスでは、単にHTMLメールを送信するメソッドを記述します。

import java.io.UnsupportedEncodingException; 
import java.util.Date; 

import javax.inject.Inject; 
import javax.mail.MessagingException; 
import javax.mail.internet.MimeMessage; 

import org.springframework.mail.MailException; 
import org.springframework.mail.SimpleMailMessage; 
import org.springframework.mail.javamail.JavaMailSender; 
import org.springframework.mail.javamail.MimeMessageHelper; 
import org.springframework.stereotype.Repository; 

import fi.vietjob.bean.mail.Mail; 

@Repository 
public class mailFeature { 
    @Inject 
    private JavaMailSender mailSender; 

    public JavaMailSender getMailSender() { 
     return mailSender; 
    } 

    public void setMailSender(JavaMailSender mailSender) { 
     this.mailSender = mailSender; 
    } 

    public void getPalaute(Mail mail, String to) { 
     SimpleMailMessage message = new SimpleMailMessage(); 
     message.setSubject(mail.getSubject()); 
     message.setText(mail.getText()); 
     message.setFrom(mail.getFrom()); 
     message.setSentDate(new Date()); 
     mailSender.send(message); 
    } 

    public void sendHTMLEmail(Mail mail, String to, String senderName) { 

     try { 
      MimeMessage mime = mailSender.createMimeMessage(); 
      MimeMessageHelper helper = new MimeMessageHelper(mime, true); 
      helper.setFrom(mail.getFrom(), senderName); 
      helper.setText(mail.getText()); 
      helper.setSubject(mail.getSubject()); 
      helper.setSentDate(new Date()); 
      helper.setTo(to); 
      mailSender.send(mime); 
     } catch (MailException e) { 
      // TODO Auto-generated catch block 
      e.printStackTrace(); 
     } catch (UnsupportedEncodingException e) { 
      // TODO Auto-generated catch block 
      e.printStackTrace(); 
     } catch (MessagingException e) { 
      // TODO Auto-generated catch block 
      e.printStackTrace(); 
     } 

    } 
} 

と私はそれを実行したとき、私はstackstraceだ：あなたはこのように、メールの送信者を作成したXMLファイルで

Answer 1

を：

<bean id="mailSender" class="org.springframework.mail.javamail.JavaMailSender"> 
    <property name="host" value="${host}"/> 
    <property name="port" value="${port}"/> 
    <property name="username" value="${username}"/> 
    <property name="password" value="${password}"/> 
    <property name="javaMailProperties"> 
     <props> 
      <prop key="mail.transport.protocol">smtp</prop> 
      <prop key="mail.smtp.auth">true</prop> 
      <prop key="mail.smtp.starttls.enable">true</prop> 
      <prop key="mail.debug">true</prop> 
     </props> 
    </property> 
</bean> 

ので、春には、Beanを作成しますIDがmailSender リポジトリに注入しようとすると、単に@Injectを使用します。だから、書いてみる@Injectと@Qualifier

を使用しよう：

@Repository 
public class mailFeature { 
    @Inject 
    @Qualifier("mailSender") 
    private JavaMailSender mailSender; 
.... 
} 

それは

を動作するはずです、私はそれが
