如果我关闭我的日食并重新开始，那么项目第一次正常工作。

答：我得到的答案是从命令行停止tomcat或重启elipse或更改端口号。

我刚刚在eclipse中安装了m2e插件，所以我无法通过命令行停止。我不想每次都重启我的eclipse并改变我的端口号。有没有其他方法可以做到这一点。我们不能从日食中停止或启动tomcat吗？

Answer 1

java.net.BindException: Address already in us

Tomcat已经处于启动模式。

要重新开始，您需要先停止它然后重新开始。或者您可以重新启动TOMCAT。它会关注停止和启动服务器。

Answer 2

您尝试重新运行应用程序而不杀死第一个tomcat服务器

java.net.BindException: Address already in use <null>:8080

首先杀死该实例。然后重新运行。

Answer 3

java.net.BindException：已在使用的地址

您遇到此问题，因为您没有关闭已经运行的tomcat实例并且您正在尝试再次运行它

所以你可以做两件事关闭第一个实例并重新运行，如果问题仍然存在，请按照以下方法更改端口。

打开server.xml搜索8080并将其更改为8081

检查this answer for closing tomcat

Answer 4

mvn tomcat:stop

在tomcat之前使用：start。

查看您的控制台视图。它有一个红色按钮来停止你的应用程序。
