将maven项目打war包并部署到Tomcat上

本文主要是介绍将maven项目打war包并部署到Tomcat上，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

1、环境：eclipse、apache-maven-3.3.3、apache-tomcat-7.0.63

2、配置：

（1）配置Tomcat的manager访问权限：在F:\software\apache-tomcat-7.0.63\conf\tomcat-users.xml下做如下修改

<tomcat-users>
<!--NOTE:  By default, no user is included in the "manager-gui" role requiredto operate the "/manager/html" web application.  If you wish to use this app,you must define such a user - the username and password are arbitrary.
-->
<!--NOTE:  The sample user and role entries below are wrapped in a commentand thus are ignored when reading this file. Do not forget to remove<!.. ..> that surrounds them.
-->
<!--<role rolename="tomcat"/><role rolename="role1"/><user username="tomcat" password="tomcat" roles="tomcat"/><user username="both" password="tomcat" roles="tomcat,role1"/><user username="role1" password="tomcat" roles="role1"/>
--><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"/>
</tomcat-users>

（2）apache-maven-3.3.3配置：为了让maven可以访问tomcat的权限，所以需要把如上创建的用户添加到settings.xml中

<servers><!-- 配置tomcat-/manager/text 访问权限 --><server><id>tomcat</id><username>admin</username><password>admin</password></server></servers>

（3）配置工程目录下的pom.xml文件，加入build，并配置tomcat7的maven插件，如下配置

	<build><!--  <finalName>hxyc</finalName> --><!-- directory缺省情况下指向target --> <!--<directory>${basedir}/target</directory>--><plugins><plugin><groupId>org.apache.maven.plugins</groupId><artifactId>maven-compiler-plugin</artifactId><version>2.3.2</version><configuration><source>1.7</source><target>1.7</target></configuration></plugin><plugin><groupId>org.apache.tomcat.maven</groupId><artifactId>tomcat7-maven-plugin</artifactId><version>2.2</version><configuration><port>8080</port><url>http://localhost:8080/hxyc</url><server>local_tomcat</server><ignorePackaging>true</ignorePackaging><contextReloadable>true</contextReloadable><!-- server、username、password对应maven的setting下的配置 --><server><id>tomcat</id><username>admin</username><password>admin</password></server><!--  <path>/${project.build.finalName}</path> --><!-- war文件路径缺省情况下指向target --><!--<warFile>${basedir}/target/${project.build.finalName}.war</warFile>--></configuration></plugin></plugins></build>

3、命令打包

在部署之前，必须先启动tomcat7服务，C:\Program Files\apache-tomcat-7.0.39\bin\startup.bat

找到要部署的工程文件根目录下，执行如下maven命令

> mvn clean install //clean是清理输出文件，install编译打包，在每次打包之前必须执行clean，才能保证发布为最新文件
