使用Maven自动部署Java Web项目到Tomcat问题小记

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>
