If i close my eclipse and start again, then project works fine for the first time. 如果我关闭日食并重新开始，则项目第一次正常运行。

Answer : I get answers for this is stop tomcat from command line or restart the elipse or change the port no. 答案：我得到的答案是从命令行停止tomcat或重新启动Elipse或更改端口号。

I just installed m2e plugin in eclipse, so i cannot stop through command line. 我只是在eclipse中安装了m2e插件，所以我无法通过命令行停止。 I dont want to restart my eclipse everytime and change my port no. 我不想每次都重新启动Eclipse并更改端口号。 Is there any other way to do this. 还有其他方法可以做到这一点。 Can't we stop or start tomcat from eclipse ? 我们不能从eclipse停止或启动tomcat吗？

java.net.BindException: Address already in us

Tomcat is already in starting mode. Tomcat已经处于启动模式。

To start again you need to stop it first and then start again.Or you can restart the TOMCAT. 要重新启动，您需要先将其停止然后再启动。或者您可以重新启动TOMCAT。 It will take care about stopping and starting server. 它将注意停止和启动服务器。

You're trying to re-run the application without killing the first tomcat server 您正在尝试重新运行应用程序而不会杀死第一个tomcat服务器 

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

Kill that instance first. 首先杀死该实例。 then re-run. 然后重新运行。

java.net.BindException: Address already in use java.net.BindException：地址已在使用中

you are encountering this problem because you are not closing an instance of tomcat which is already running and you are trying to run it again 您正在遇到此问题，因为您没有关闭已在运行的tomcat实例，并试图再次运行它

so you can do two things either close first instance and re-run and if problem persists change the port by following method. 因此，您可以执行以下两项操作：关闭第一个实例并重新运行，如果问题仍然存在，请通过以下方法更改端口。

open server.xml search for 8080 and change it to 8081 打开server.xml搜索8080并将其更改为8081

check this answer for closing tomcat 检查此答案以关闭tomcat

mvn tomcat:stop

Use this before tomcat:start. 在tomcat：start之前使用它。

See your console view. 查看您的控制台视图。 It has a red button to stop your application. 它有一个红色按钮来停止您的应用程序。
