【问题描述】：
我正在尝试使用 java 邮件 api 与用户 loginId 密码和主机名连接到邮件服务器。但是，如果任何一个 id 无法建立连接，那么即使它们具有正确的凭据，以下 id 也无法授权。
我是否必须在循环后关闭存储值。
sessions = Session.getDefaultInstance(properties);
store = sessions.getStore(emailAccType);
store.connect(emailHost,emailId, emailPwd);
我需要在 try/catch 的 finally 块中关闭什么。
以下错误。
javax.mail.MessagingException: Connect failed;

它是第一次执行，但如果失败，就会出现这个问题。 提前致谢
