Spring 4 MVC 中的 javax/mail/MessagingException

Question

我有一个应用程序(使用注释的 Spring 4 MVC+Hibernate 4+MySQL+Maven 集成示例)，使用基于注释的配置将 Spring 与 Hibernate 集成。

启动应用程序时出现此错误。

我在 pom.xml 中有这个

 <dependency>
            <groupId>javax.mail</groupId>
            <artifactId>mail</artifactId>
            <version>1.4</version>
        </dependency>

我检查了存储库并且在那里:

/Users/paquirrin/.m2/repository/javax/mail/mail/1.4

我已经更新了 Maven 项目 1000 次，但它不起作用!

我在本地主机的 tomcat7 中运行该项目

似乎您使用了错误的依赖项。请尝试以下操作:

<dependency>
    <groupId>javax.mail</groupId>
    <artifactId>mailapi</artifactId>
    <version>1.4.3</version>
</dependency>

确保刷新依赖项，并重建项目。
