【问题描述】：
我正在使用 tomcat7-maven-plugin 部署我的 spring 批处理管理应用程序，
下面是我在pom中的配置，
<plugin>
<groupId>org.apache.tomcat.maven</groupId>
<artifactId>tomcat7-maven-plugin</artifactId>
<version>2.1</version>
<configuration>
<!-- Tomcat 7 has a different manager path - text - than other versions -->
<url>http://localhost:8081/manager/text</url>
<username>myusername</username>
<password>mypassword</password>
<path>/${project.build.finalName}</path>
<update>true</update>
</configuration>
</plugin>
我在跑步，
mvn clean install tomcat7:deploy
虽然成功完成，但完成此命令所需的时间太长，几乎（4-5 分钟）。
下面是命令的输出。上传war文件后需要很长时间才能收到响应。您可以在输出下方观察，耗时 4.16 分钟。
它运行得非常快，直到它显示消息“已上传..”但之后它一直等待响应 4-5 分钟。
我需要在多台服务器（5 台服务器）上部署应用程序，因此需要 25 分钟，这对于仅部署来说太长了。

【问题讨论】：
-
那是因为
tomcat7:deploy等待应用程序启动而不是Tomcat，这可能需要很长时间。 -
如果我手动启动tomcat，应用程序会在tomcat启动后立即启动。使用maven插件时发生这种情况有什么原因吗？
-
很明显，当你重新部署应用程序时，它会停止旧版本，取消部署它，然后部署新版本并启动它
-
首先我建议清理我的构建，它有很多警告。
