在pom.xml中添加依赖时语法如下
<dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>1.2.6</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aop</artifactId> <version>1.2.6</version> </dependency>
有这样一个问题,在spring的依赖中,我们需要引用一系列版本的spring,如版本1.2.6。每次都写不利于维护
解决办法:
在pom.xml定义properties标签
<properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <spring.version>1.2.6</spring.version> <developer.organization><![CDATA[xy公司]]></developer.organization> </properties>
<dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aop</artifactId> <version>${spring.version}</version> </dependency>
