首先在pom.xml中对需要的几个maven插件进行配置，配置如下:
<!-- 下面进行maven项目的打包配置 -->
<build>
<plugins>
<!-- 用于maven编译的plugin -->
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.1</version>
<configuration>
<fork>true</fork>
<defaultLibBundDir>lib</defaultLibBundDir>
<source>1.8</source>
<target>1.8</target>
<encoding>UTF-8</encoding>
<!-- 如果配置了JAVA_HOME,下面应该可以不用配
<executable>E:\JDK\jdk1.8\bin\javac.exe</executable> -->
</configuration>
</plugin>
<!-- resource插件 -->
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-resources-plugin</artifactId>
<version>2.7</version>
<configuration>
<encoding>UTF-8</encoding>
</configuration>
</plugin>
<!-- 用于拷贝maven依赖的plugin -->
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>
<version>2.10</version>
<executions>
<execution>
<id>copy-war</id>
<phase>package</phase>
<goals>
<goal>copy</goal>
</goals>
<configuration>
<artifactItems>
<artifactItem>
<groupId>${project.groupId}</groupId>
<artifactId>${project.artifactId}</artifactId>
<type>${project.packaging}</type>
</artifactItem>
</artifactItems>
<!-- 将打好的war包拷贝到指定目录之下，我这里直接到tomcat下 -->
<outputDirectory>F:/tomcat/apache-tomcat-7.0.70/webapps</outputDirectory>
<includes>
<include>*.war</include>
</includes>
</configuration>
</execution>
</executions>
</plugin>
<!-- 打war包配置pligin 默认是打包到target目录下-->
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<version>2.6</version>
<configuration>
<!-- war包不要带版本号，默认是有的 -->
<warName>${project.artifactId}</warName>
<webResources>
<resource>
<!-- 将资源属性配置文件放到classpath下 -->
<directory>src/main/resources</directory>
<targetPath>WEB-INF/classes</targetPath>
<filtering>true</filtering>
</resource>
</webResources>
</configuration>
</plugin>
</plugins>
</build>其次，项目右键Run As --》 maven clean ---》maven build...
最后就到了上面配置的
<outputDirectory>F:/tomcat/apache-tomcat-7.0.70/webapps</outputDirectory>
