deploy project to Tomcat from Eclipse
提问by Dónal
I'm trying to deploy a multi-module Maven project from Eclipse to a local Tomcat. The project has the following structure:
我正在尝试将多模块 Maven 项目从 Eclipse 部署到本地 Tomcat。该项目具有以下结构：
root [packaging: pom]
|
|--- domain [packaging: jar]
|
|--- manager [packaging: jar]
|
|--- web [packaging: war]
I import all the projects into Eclipse, then add the "Dynamic Web Module" facet to the web project
我将所有项目导入 Eclipse，然后将“动态 Web 模块”方面添加到 Web 项目中
In the Runtimes tab of the same dialog, I configure the project to use a (local) Apache Tomcat v6.0 runtime.
在同一个对话框的 Runtimes 选项卡中，我将项目配置为使用（本地）Apache Tomcat v6.0 运行时。
I then right-click on the project and choose "Run As -> Run on Server" from the menu. In the following dialog I (again?) choose "Tomcat v6.0 Server"
然后我右键单击该项目并从菜单中选择“运行方式 -> 在服务器上运行”。在下面的对话框中，我（再次？）选择“Tomcat v6.0 Server”
In the following dialog, I add the web project to the list of configured projects
在以下对话框中，我将 Web 项目添加到已配置项目列表中
When I click "Finish", it appears from the console messages that the server has started, but when I go to http://localhost:8080/web/in a browser I get a 404. I also tried http://localhost:8080/and that also returns a 404, what am I doing wrong?
当我单击“完成”时，从控制台消息中显示服务器已启动，但是当我在浏览器中访问http://localhost:8080/web/ 时，我得到一个 404。我也尝试过http://localhost :8080/并且也返回 404，我做错了什么？

I also tried http://localhost:8080/and that also returns a 404.
我也试过http://localhost:8080/并且也返回 404。
I would infer that either Tomcat is not listening on port 8080, for the behavior is to display the contents of $CATALINA_HOME/webapps/ROOT/index.htmlas the welcome page. You might want to verify that Tomcat is configured to listen on port 8080 in the first place. The $CATALINA_HOME/conf/server.xmlfile should have entry similar to one listed below:
我会推断 Tomcat 没有侦听端口 8080，因为行为是将 的内容显示$CATALINA_HOME/webapps/ROOT/index.html为欢迎页面。您可能首先要验证 Tomcat 是否配置为侦听端口 8080。该$CATALINA_HOME/conf/server.xml文件应具有类似于下面列出的条目：
<Server port="8005" shutdown="SHUTDOWN">
...
<Service name="Catalina">
...
<Connector port="8080" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443" />
If you've got this right, but you are seeing a 404 response, then obviously something is wrong with the configuration. Either $CATALINA_HOME/webapps/ROOTdoes not exist, or something else which you might determine by looking at the logs in the $CATALINA_HOME/logsdirectory.
如果您做对了，但您看到的是 404 响应，那么显然配置有问题。要么$CATALINA_HOME/webapps/ROOT不存在，要么您可以通过查看$CATALINA_HOME/logs目录中的日志来确定其他内容。
When I click "Finish", it appears from the console messages that the server has started, but when I go to http://localhost:8080/web/in a browser I get a 404
当我单击“完成”时，从控制台消息中显示服务器已启动，但是当我在浏览器中访问http://localhost:8080/web/ 时，我收到 404
Assuming that Tomcat has been configured successfully, this described behavior is likely if you do not have a welcome file listed in web.xml. The structure of the welcome-file-listis similar to the one listed below:
假设 Tomcat 已成功配置，如果您没有在web.xml. 的结构welcome-file-list类似于下面列出的结构：
<web-app>
...
<welcome-file-list>
<welcome-file>somePage.html</welcome-file>
</welcome-file-list>
...
</web-app>
Quite obviously, you'll need to have valid HTML in the welcome page. You could also have a JSP page to act as the welcome page.
很明显，您需要在欢迎页面中有有效的 HTML。您还可以有一个 JSP 页面作为欢迎页面。
Maven integration with Eclipse
Maven 与 Eclipse 的集成
I'm putting this in a separate section, as I'm unsure if your Eclipse project is setup correctly in the first place. Typically one would use either of m2eclipseor the maven-eclipse-pluginto configure a WTP project in Eclipse.
我把它放在一个单独的部分，因为我不确定你的 Eclipse 项目是否首先设置正确。通常，可以使用m2eclipse或maven-eclipse-plugin来配置 Eclipse 中的 WTP 项目。
If you have added the Maven nature (using the m2eclipse plug-in) to the project, then you must know that m2eclipse has the tendency to revert any changes that might conflict the ones that it generates. For instance, m2eclipse would set the version Java facet to the sourceversion specified for the maven-compiler-pluginin your pom.xml.
如果您已将 Maven 特性（使用 m2eclipse 插件）添加到项目中，那么您必须知道 m2eclipse 倾向于还原任何可能与其生成的更改冲突的更改。例如，m2eclipse 会将版本 Java facet 设置source为maven-compiler-plugin在 pom.xml 中为 指定的版本。
Also, it might be important to run the packagephase, before deploying the application on the server. I've been tripped by this behavior on some occasions.
此外，package在服务器上部署应用程序之前运行该阶段可能很重要。在某些情况下，我被这种行为绊倒了。

Success!!!
成功！！！
When I added the dynamic module Eclipse incorrectly created a WebContent directory. I deleted this directory and made the following change to the file in the .settingsdirectory named org.eclipse.wst.common.component
当我添加动态模块时，Eclipse 错误地创建了一个 WebContent 目录。我删除了这个目录并对.settings名为的目录中的文件进行了以下更改org.eclipse.wst.common.component
<wb-resource deploy-path="/" source-path="/src/main/webapp"/>
<!--
<wb-resource deploy-path="/" source-path="/WebContent"/>
-->
