配置全局变量控制版本号,修改起来比较快速方便,使用方式分两步:

第一步:在pom.xml文件中的<dependencies>标签前新增一个标签<properties></properties>

 <properties><project.artifactId>CarCenterSys</project.artifactId><springside.version>4.2.2.GA</springside.version><spring.version>4.2.5.RELEASE</spring.version><mybatis.version>3.2.5</mybatis.version><mybatis-spring.version>1.2.2</mybatis-spring.version><logback.version>1.1.1</logback.version><tomcat-jdbc.version>8.0.35</tomcat-jdbc.version><jackson.version>2.3.1</jackson.version></properties><dependencies>......</dependencies>

第二步:使用方式为${之前定义的标签名称}

<dependencies><dependency><groupId>org.springframework</groupId><artifactId>spring-test</artifactId><version>${spring.version}</version><scope>test</scope></dependency><dependency><groupId>ch.qos.logback</groupId><artifactId>logback-classic</artifactId><version>${logback.version}</version><scope>runtime</scope></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-webmvc</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-jdbc</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-tx</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.mybatis</groupId><artifactId>mybatis</artifactId><version>${mybatis.version}</version></dependency><dependency><groupId>org.mybatis</groupId><artifactId>mybatis-spring</artifactId><version>${mybatis-spring.version}</version></dependency><!-- connection pool --><dependency><groupId>org.apache.tomcat</groupId><artifactId>tomcat-jdbc</artifactId><version>${tomcat-jdbc.version}</version><scope>runtime</scope></dependency>
</dependencies>

OK,是不是方便很多呢?
