1. 在POM中使用 统一/指定/特定 的Spring版本号
<properties> <spring.version>4.1.6.RELEASE</spring.version> <spring.security.version>3.2.3.RELEASE</spring.security.version> </properties> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework.security</groupId> <artifactId>spring-security-core</artifactId> <version>${spring.security.version}</version> </dependency>
2. 如果项目需要用到"不存在于Maven Central Repository"的特定版本的spring依赖包, 比如Milestone, 或者snapshot版, 则可以在POM中定义repository.
Maven会去对应url中下载依赖包到本地.
<repositories> <repository> <id>repository.springframework.maven.milestone</id> <name>Spring Framework Maven Milestone Repository</name> <url>http://repo.spring.io/milestone/</url> </repository> </repositories> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>3.2.0.RC2</version> </dependency>
