SpringMVC 整合Mongodb

引言

平时都在用 SpringMVC 进行开发，但是，基本上都是在用 SpringMVC+Mybatis+MySQL 进行开发。对于 Mongodb 只是听说过，
自己实际没有操作过，近期，在工作之余决定研究一下 Mongodb 。

那么，开始进入正题吧，此次我构建的项目是 SpringMVC+Mongodb+Maven ，有不对之处，还望指出。

作为一个 Maven 工程，我们还是先从 pom.xml 文件开始把,在 pom.xml 里配置我们的工程所依赖的 jar。
pom.xml

接着就是web.xml 文件，有一点我们需要明确的就是， web.xml 文件并不是 web 工程所必须的，但是，一般情况下，我们都是以 web.xml 作为我们 web工程的
入口。
web.xml
