我在处理请求时捕获了一个I/O异常(java.net.SocketException):Connection reset by peer: socket write error问题在使用maven插件部署tomcat时
这个问题困扰了我好几天。由于 connection reset by peers 错误，我无法使用 tomcat7:deploy 通过 maven 插件上传我的 war 文件。
这是我的 pom.xml 的一部分

并且配置了远程tomcat-user.xml。
我不知道如何解决这个问题。如果我可以提供任何对故障排除有用的信息，请告诉我。
提前致谢
最佳答案
试试这些，
使用redeploy代替deploy
tomcat 中的默认 war 大小为 50 MB，如果您的 war 大于 50 MB，请尝试增加它
列出的许多用户导致我在 tomcat-users.xml 中缺少角色。如果缺少，请尝试添加管理脚本角色，Question Link
Tomcat7 插件可能会从 maven conf settings.xml 而不是 .m2\settings.xml 中选取服务器详细信息。在该文件中添加服务器信息可能会解决问题。
