从3升级到spring之后。x到4.3.2，JavaMailSender和VelocityEngine的自动连接失败

Question

原因：org。springframework。豆。工厂BeanCreationException:无法自动关联字段：私有组织。springframework。邮政javamail。JavaMailSender.com。xxx。服务impl。NotificationServiceImpl。邮件发送者；嵌套的异常是org。springframework。豆。工厂NoSuchBeanDefinitionException:找不到[org.springframework.mail.javamail.JavaMailSender]类型的符合依赖项条件的bean：至少需要1个符合此依赖项autowire候选项条件的bean。依赖项注释：{@org.springframework.beans.factory.annotation.Autowired（required=true）}

其他依赖项：

• javax。邮件-1.4.7

package com.xxx.service.impl;

@Service("notificationService")
public class NotificationServiceImpl implements NotificationService {
    @Autowired
    private JavaMailSender mailSender;
}

所有依赖项都已正确添加，JavaMailSender类也存在于spring-context-support-xxx.jar中，但找不到它没有自动运行的原因。有人能帮忙吗？

Answer 1

尝试从. m2目录中删除Spring文件夹。然后更新您的maven依赖项并重建项目。
