maven发布项目到本地tomcat

添加plugin：

                       <plugin>
<!-- 使用maven的tomcat插件打包并部署war文件到tomcat -->
<groupId>org.apache.tomcat.maven</groupId>
<artifactId>tomcat7-maven-plugin</artifactId>
<version>2.0</version>
<configuration>
    <path>/${project.build.finalName}</path>  
<url>http://localhost:8080/manager/text</url>
<server>tomcat</server>
<username>tomcat</username>
<password>password</password>
</configuration>
</plugin>

<plugin>
<!-- 这里版本为1.7 请注意编译版本 否则会报错 -->
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.1</version>
<configuration>
<source>1.7</source>
<target>1.7</target>
<encoding>${project.build.sourceEncoding}</encoding>
</configuration>
</plugin>

其中用户名和密码的配置可以理解为maven为了和本地tomcat打交道而由tomcat的配置的口令，首先要在tomcat安装目录下conf文件夹下的tomcat-users.xml文件中配置：

<tomcat-users>
<!--
  NOTE:  By default, no user is included in the "manager-gui" role required
  to 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 comment
  and thus are ignored when reading this file. Do not forget to remove
  <!.. ..> that surrounds them.
-->
    <!-- maven发布到tomcat -->
<role rolename="manager-gui"/> 
 <role rolename="manager-script"/> 
 <user username="tomcat" password="password" roles="manager-gui, manager-script"/>

</tomcat-users>

这里配置好后，启动tomcat，在浏览器输入localhost：8080/manage会让你输入用户名密码，输入这里配置的用户名/密码，若验证通过会跳到tomcat web application Manager页面，就说明该配置是成功的，就可以往下进行；若验证不通过，会跳到一个说明页面，里面有对各role的说明（想了解上面role的童鞋请自行查看），此时再修改配置，直至验证成功。

<servers>
    <!-- server
     | Specifies the authentication information to use when connecting to a particular server, identified by
     | a unique name within the system (referred to by the 'id' attribute below).
     |
     | NOTE: You should either specify username/password OR privateKey/passphrase, since these pairings are
     |       used together.
     |
    <server>
      <id>deploymentRepo</id>
      <username>repouser</username>
      <password>repopwd</password>
    </server>
    -->
    <server>  
 <id>tomcat</id> 
 <username>tomcat</username> 
 <password>password</password>  
    </server> 

  </servers>

配置maven的settings.xml文件，至于settings.xml文件在你机器的哪里，请自行查找。这里的用户名和密码都与tomcat-users.xml中验证通过的用户名密码一致，这里的‘id’要与pom文件的<server> tomcat</server>一致，当然pom文件的用户名和密码也要对应。

共有三处进行了用户名密码配置。

选择eclipse的绿色启动按钮的下拉列表的run configurations...，新增一个maven指令“tomcat7:deploy”，运行指令前先启动tomcat，

不出意外就发布成功。
