注意:官方文档和案例配置都是旧版本的配置案例,spring-data-mongo从1.0.0.M1到1.0.0.M3的版本叫做Spring Data Document。1.0.0.M4开始更名为Spring Data MongoDB 1.0.0 M4,不过官网并没有特别说明,乍一看有点莫名其妙,尤其是MongoTemplate从org.springframework.data.document.mongod移动到org.springframework.data.mongodb.core,官网的HelloWorldExample却还是用org.springframework.data.document.mongodb做配置案例。多少会导致使用时的误导。
(4)配置spring-servlet.xml

注意:spring-servlet.xml的命名是根据web.xml中配置spring DispatcherServlet的名字 (<servlet-name>spring</servlet-name>)加上-servlet命名的。
