在centOS Linux中运行的Spring Java邮件程序引发异常
我按照这里的说明编写了一个注入SpringMail的java程序-Spring EMail。我编写了一个JUNIT类来测试它。所有这些都是作为一个更大项目的一部分发生的，而这个大项目是在oracle virtual box linux centOS机器上开发的。如果我在centOS中运行测试用例，我会看到这个异常。我查看了一些linux论坛，没有看到任何与之相关的答案。我认为我没有正确地搜索，因为这是我在VBOX和Linux中远程开发的第一个项目。专家们能帮忙吗？我确保我的SMTP主机看起来不错
我找到了一些帮助here - sendmail issue in centOS -和here - spring forums-但不确定我是否能按照所有说明操作

# 1 楼答案
您是否已检查防火墙设置？您的centOS虚拟机可能不允许访问电子邮件服务器
电子邮件服务器是否与centOS或远程服务器位于同一台机器上
# 2 楼答案
我遇到了同样的错误。我的配置是（从pom.xml中删除）
和Java邮件
升级到JavaMail 1.4.5后，问题消失了
# 3 楼答案
您使用的是什么版本的JavaMail？您使用的是哪个版本的JDK？ 这一例外是否可复制
您在JavaMail代码中遇到了一个永远不会发生的断言错误。 它断言它持有当前对象的锁。自方法制定以来 断言只从同步方法调用，特别是 服务connect方法已同步，不应发生这种情况
