写这篇文章也做了下思考，首先是本人技术欠佳。但就是喜欢研究一些东西。因为在此之前有很多的朋友已经写过类似的，很多我也看过，但是讲解的不够深入。对有些朋友提出的问题不能给出答案。在这里，我根据我目前的能力对其进行整理。并最终运行成功。
在测试过程中出现过一下问题：
1、org/springframework/data/mapping/context/MappingContextAware
2、src-resolve: Cannot resolve the name 'repository:repository' to a(n) 'type definition'
以上都是版本不匹配引起的。特别是第二个错误我看有些解决时候提到了jpa，但是我这里没有使用jpa后来我是把spring-data-commons的包替换了个版本就不出现了。
我先说下我的开发环境：
myeclipse 6.5
MongoDB 2.0.8
spring 3.0.4
最后就是下面2个(这两个版本不对就容易出现各种各样的，杂七杂八的问题) 这里我就给出我所采用的版本
spring-data-document
spring-data-commons
有所改变所有版本必须要对应好下面是jar下载地址
http://www.springsource.org/spring-data/mongodb
http://www.springsource.org/spring-data/commons
下载版本分别为：
spring-data-commons-dist-1.4.0.M1
spring-data-document-1.0.0.M2.zip
下面给出我工程的图片
然后就开始我们开发之旅吧!
首先新建application.xml配置文件

然后编写操作mongodb的接口

运行出现一下日志，就没什么问题。
