Failure to transfer org.springframework:spring-jdbc:jar:2.5.6 from http://repo1.maven.org/maven2 was cached in the local repository, resolution will not be reattempted until the update interval of central has elapsed or updates are forced. Original error: Could not transfer artifact org.springframework:spring-jdbc:jar:2.5.6 from/to central (http://repo1.maven.org/maven2): No response received after 60000
只时我打开window command窗口，在dos下进入到pom.xml文件所在目录，执行如下命令
mvn -U test
就好了
