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。
