mysql - Maven - Tomcat 7 - Hibernate MySQL : Broken Pipe Exception when doing mvn deploy

Question

对于我学校的编程考试，我们需要能够在 Tomcat (7) 服务器上使用 maven 构建和部署 Spring MVC 项目。这些东西大部分都在工作。 mvn clean install 提供了 BUILD SUCCESS，这很好，我可以设置我的 tomcat 服务器。但是，当我尝试使用例如 mvn tomcat7:deploy 来运行或部署我的项目时，我收到了损坏的管道异常，它看起来像这样:

[ERROR] Failed to execute goal org.apache.tomcat.maven:tomcat7-maven-plugin:2.2:deploy (default-cli) on project SpringMVCBlog: Cannot invoke Tomcat manager: Broken pipe -> [Help 1]

完整的堆栈跟踪 (mvn tomcat7:deploy -e) 如下:

[ERROR] Failed to execute goal org.apache.tomcat.maven:tomcat7-maven-plugin:2.2:deploy (default-cli) on project SpringMVCBlog: Cannot invoke Tomcat manager: Protocol wrong type for socket -> [Help 1]

我已经为此苦苦挣扎了很长时间，但似乎一直找不到解决方案。当我使用 glassfish 服务器在 IDE (IntelliJ) 中运行此项目时，它可以工作，但目标是使用终端(我在 Mac 上)运行它并将其部署在 Tomcat 服务器上。

我已经搜索过，但没有太多关于破损管道异常的信息。我发现它与Hibernate和MySQL有关。我在应用程序中有一个基本的 Hibernate 结构，只有一个基本的 hibernate.cfg/xml 和一些设置，以及一个用于获取 session 的 Util 类，以便我可以在数据库上保存和更新。损坏的管道与连接池有关，据我所知，我在项目中没有使用连接池。

我真的希望有人能帮助我，这个问题非常令人沮丧。请告诉我是否需要任何额外的代码!

只需使用

mvn tomcat7:redeploy

如果您的应用程序已部署。

否则，您需要先取消部署应用程序，然后再执行mvn tomcat7:deploy
