從3.x升級彈簧4.3.2之後，JavaMailSender的自動裝配和VelocityEngine失敗

Question

Caused by: org.springframework.beans.factory.BeanCreationException: Could not autowire field: private org.springframework.mail.javamail.JavaMailSender com.xxx.service.impl.NotificationServiceImpl.mailSender; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [org.springframework.mail.javamail.JavaMailSender] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}

<!-- Configure Velocity for sending e-mail --> 
<bean id="velocityEngine" class="org.springframework.ui.velocity.VelocityEngineFactoryBean">

      </prop> 
      <prop key="velocimacro.library"></prop> 
     </props> 
    </property> 
</bean> 

其他依賴關係： - javax.mail - 1.4.7， org.apache.velocity - 中還存在1.7

package com.xxx.service.impl; 
@Service("notificationService") 
public class NotificationServiceImpl implements NotificationService { 
@Autowired 
private JavaMailSender mailSender; 
} 

所有依賴關係正確添加，JavaMailSender類春季上下文-support-xxx.jar，但找不到自動裝配的原因。有人可以幫忙嗎？

嘗試從.m2目錄中刪除彈出文件夾。然後更新你的Maven依賴項並重建項目。
