Tomcat未能在Eclipse中啓動--java.net.BindException：已經在使用的地址

Question

我是Tomcat和Eclipse的新手，但一直在尋找天的解決方案。我已經安裝了Tomcat v7.0，並且可以從終端啓動/停止它，但是我無法從Eclipse中使用它。我下面的教程在http://www.vogella.de/articles/EclipseWTP/article.html#jspservlets，但是當我嘗試運行我的servlet我得到警告：「服務器的Tomcat V7.0服務器在本地主機無法啓動」與控制檯輸出：

的netstat沒有按在嘗試運行Tomcat之前，不會顯示正在使用的端口8080,8005或8009，因此似乎不是問題所在。任何想法出了什麼問題？

Answer 1

看起來，當您安裝Tomcat時，它決定在服務模式下運行，並且必須在啓動系統時運行。因此，當你通過eclipse啓動tomcat時發生錯誤。使用server.xml中的其他端口可能無法解決你的問題。我猜測是tomcat的另一個實例已經在運行。你可以在啓動之前檢查另一個tomcat實例的taskmanager是否正在運行它從日食？ 也可以發佈netstat運行結果嗎？

Answer 2

更改Tomcat的端口設置：

看來Tomcat的已經集成在Eclipse中。因此，在Eclipse中應該有一個名爲「Servers」的項目，您可以找到您的Tomcat配置節點。更改server.xml中的端口屬性。當然，這個插件提供了許多與Tomcat集成的方法，但基本的想法是更改server.xml。

第1步：進入C：\ WINDOWS \ SYSTEM32 \ drivers \ etc下

第2步：

找到hosts文件，用記事本管理模式打開

第3步：

用127.0.0.1替換本地主機IP

例如

# Copyright (c) 1993-2009 Microsoft Corp. 
# 
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows. 
# 
# This file contains the mappings of IP addresses to host names. Each 
# entry should be kept on an individual line. The IP address should 
# be placed in the first column followed by the corresponding host name. 
# The IP address and the host name should be separated by at least one 
# space. 
# 
# Additionally, comments (such as these) may be inserted on individual 
# lines or following the machine name denoted by a '#' symbol. 
# 
# For example: 
# 
#  102.54.94.97  rhino.acme.com   # source server 
#  38.25.63.10  x.acme.com    # x client host 

# localhost name resolution is handled within DNS itself. 
    127.0.0.1  localhost 
# ::1    localhost 

第4步：

保存該文件並運行服務器
