我可以ping远程服务器ip，因此没有连接问题。我可以在tomcat中运行相同的代码，并且工作正常。当我在web领域部署它时，相同的代码给我上面的错误。尝试堆栈溢出的其他东西没有工作。罐子是activation-1.1.jar，mail-1.4.5.jar。任何指针都有帮助。

Answer 1

好吧，在我们的测试中，我们将这个Gradle依赖项用于邮件适配器：

mailVersion = '1.5.5'

testRuntime "com.sun.mail:javax.mail:$mailVersion"
testRuntime "com.sun.mail:smtp:$mailVersion"
testRuntime "com.sun.mail:pop3:$mailVersion"
testRuntime "com.sun.mail:imap:$mailVersion"

因此，请考虑为您的项目添加com.sun.mail:imap:1.5.5。

Answer 2

感谢您的回答，评论肯定有帮助。

最初我使用了以下代码： -

    <dependency>
        <groupId>javax.mail</groupId>
        <artifactId>javax.mail-api</artifactId>
        <version>1.5.3</version>
    </dependency>
    <dependency>
        <groupId>com.sun.mail</groupId>
        <artifactId>javax.mail</artifactId>
        <version>1.5.3</version>
    </dependency>

这解决了imap提供商的问题。所有都在本地工作但是当我在Websphere上部署代码时，我得到了类转换异常

caused by: java.lang.ClassCastException: com.sun.mail.handlers.text_plain incompatible with javax.activation.DataContentHandler

尽管text_plain从DataContenHandler扩展但仍在抱怨不同的类，它告诉它在其他地方被加载。然后排除激活jar，如下所示，以使其工作

    <dependency>
        <groupId>javax.mail</groupId>
        <artifactId>javax.mail-api</artifactId>
        <version>1.5.3</version>
        <exclusions>
            <exclusion>
                <artifactId>activation</artifactId>
                <groupId>javax.activation</groupId>
            </exclusion>
        </exclusions>
    </dependency>
    <dependency>
        <groupId>com.sun.mail</groupId>
        <artifactId>javax.mail</artifactId>
        <version>1.5.3</version>
        <exclusions>
            <exclusion>
                <artifactId>activation</artifactId>
                <groupId>javax.activation</groupId>
            </exclusion>
        </exclusions>
    </dependency>

谢谢你们。
