springMVC+hibernate配置

hibernate由spring管理，配置文件如下：

applicationContext.xml

有了applicationContext再在web.xml在配置一下便可同时使用spring和hibernate了，但是要使用spring mvc ，还得在web里做一点手脚，具体如下：

如上面配置文件的注释所说，由于配置了spring mvc ，还得有相关的文件，以上面的配置对应的文件名为:

springmvc-servlet.xml

按照本文所提到的配置文件配置的话，三个文件全部都放在web-inf里面，其中springmvc-servlet.xml里面配置的信息转换用到了两个外加的包

jackson-core-asl-1.4.2.jar

jackson-mapper-asl-1.4.2.jar

本文章主要是配置文件的编写，所以不涉及JAVA代码
