测试JPA的时候出现了如下信息：

SLF4J: slf4j-api 1.6.x (or later) is incompatible with this binding.
SLF4J: Your binding is version 1.5.5 or earlier.
SLF4J: Upgrade your binding to version 1.6.x. or 2.0.x
原来是版本的问题：
到http://www.slf4j.org/download.html这里下载最新的jar文件并将slf4j-api-1.6.3.jar和slf4j-log4j12-1.6.3.jar这两个添加进去之后搞定。
接受自己的失败面，是一种成熟，更是一种睿智
