使用Maven自动部署Java Web项目到Tomcat问题小记

来源：互联网发布：mac迅雷怎么看片编辑：程序博客网时间：2024/06/05 17:14

不过我的问题都不是上面两个，我的问题是自动部署命令写错了，应该是mvn tomcat7:deploy命令，而我之前用的是mvn tomcat:deploy命令

tomcat-users.xml

<role rolename="admin-gui"/>

<role rolename="admin-script"/>

<role rolename="manager-gui"/>

<role rolename="manager-script"/>

<role rolename="manager-jmx"/>

<role rolename="manager-status"/>

<user username="admin" password="admin" roles="manager-gui,manager-script,manager-jmx,manager-status,admin-script,admin-gui"/>

maven/config/ settings.xml

<server>

<id>myserver</id>

<username>admin</username>

<password>admin</password>

</server>

<!-- tomcat7插件 -->

<plugin>

<groupId>org.apache.tomcat.maven</groupId>

<artifactId>tomcat7-maven-plugin</artifactId>

<version>2.2</version>

<configuration>

<url>http://localhost:8080/manager/text</url>

<server>myserver</server>

<path>/${project.artifactId}</path>

<update>true</update>

<username>admin</username>

<password>admin</password>

<update>true</update>

<uriEncoding>UTF-8</uriEncoding>

</configuration>

</plugin>

“Application already exists at path”问题 使用tomcat7-maven-plugin插件部署到tomcat服务器时，当服务器上已经有相同名字的项目就会导致

FAIL - Application already exists at path ...

解决方法是在pom.xml文件中配置tomcat7-maven-plugin插件时加入参数update

“web.xml which will be ignored ”问题在使用Maven 编译项目的时候会出现：

[WARNING] Warning: selected war files include a WEB-INF/web.xml which will be ignored(webxml attribute is missing from war task, or ignoreWebxml attribute is specified as 'true')

解决方法是添加下面这样一个plugin即可：

<plugin>  <groupId>org.apache.maven.plugins</groupId>  <artifactId>maven-war-plugin</artifactId>  <version>2.1.1</version>  <configuration>     <packagingExcludes>WEB-INF/web.xml</packagingExcludes>  </configuration></plugin>
