Question

我正在运行一个mvn clean tomcat7：在我的项目上运行并且无法找出错误。它启动，但我永远无法访问localhost：8080上的项目。我尝试过查看此错误并测试我的端口，但没有任何效果。

这是我得到的：

我认为这只是一个小于1024的端口，只能由root用户打开。您无法打开1024以下的端口，如果您没有root权限，并且您在评论中发布的代码中，您似乎试图打开端口80，而不是8080.

转到tomcat配置并将端口更改为8080或某个端口＆gt; 1024

<plugin>
        <groupId>org.apache.tomcat.maven</groupId>
        <artifactId>tomcat7-maven-plugin</artifactId>
        <version>2.3-SNAPSHOT</version>
        <configuration>
          <url>http://localhost:8080/manager/text</url>
        </configuration>
</plugin>

或您想要的其他端口，但是1024

Maven tomcat7构建java.net.BindException
