给tomcat配置用户名密码##

在tomcat文件夹中conf文件夹的tomcat-users.xml中进行配置

<?xml version='1.0' encoding='cp936'?><tomcat-users><role rolename="manager-gui"/>
  <role rolename="manager-script"/>
  <user username="username" password="password" roles="manager-gui,manager-script"/></tomcat-users>

在maven工程的pom.xml中添加如下代码##

    <build>
        <pluginManagement>
            <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>  
                <url>http://localhost:8080/manager/text</url>  
                <username>username</username>  
                <password>password</password>  
                <path>/${project.artifactId}</path>  
            </configuration>  
        </plugin> 

    </plugins>
        </pluginManagement>
        <finalName>maven2</finalName>
    </build>

部署应用##

->Run As->Maven build…->在Goals里面输入tomcat7:deploy
注意：部署之前一定要把tomcat打开。
然后在浏览器中输入http://localhost:8080/maven2/就可以访问了。
