maven中spring部分源码无法下载

在eclipse中使用mvn进行spring开发时，修改pom.xml后提示如下信息：

Missing artifact com.mchange.c3p0:com.springsource.com.mchange.v2.c3p0:jar:0.9.1.2
Missing artifact org.apache.commons:com.springsource.org.apache.commons.logging:jar:1.1.1
Missing artifact org.apache.log4j:com.springsource.org.apache.log4j:jar:1.2.15

在stackoverflow查了下发现在pom.xml添加如下仓库即可，原始链接
