    问题缘由,maven不知道你引用的jar包的版本,导致无法获取这个jar,所以你必须指定一个版本号,${spring.version}为引用一个变量,必须在pom.xml中声明,上面错误是我从一个已有项目中直接copy过来导致,初次接触maven不懂这些,还需要把以下配置copy过来.

            <properties>
            <slf4j.version>1.7.5</slf4j.version>
            <logback.version>1.0.13</logback.version>
            <spring.version>3.2.3.RELEASE</spring.version>
            <jersey.version>2.2</jersey.version>
        </properties>
