sping整合MongoDB (吐血经验)

最近老师叫我们写一个项目练练MongoDB的使用, 我想着就用spring + springMVC + Mongodb来写. 这简直就是给自己挖坑往里面跳 哎哎哎!!!

下面就分享下我的经历

1.新建一个spring +web 的项目 (我用的是idea) , 开始项目部署

第一步 添加Exploded到项目中

第三步 添加tomcat到项目中(这一步很重要)

点击右面的 + 号 添加tomcat

第四步添加MongoDB所需要的jar包

lib包

上面那几个对勾一定要和我的一样, 第二对勾是添加MongoDB 所依赖的库.
由于我们在新建项目的时候idea就帮我们添加了spring5 最新版的jar包. 所以我们要选
spring-data-mongodb-2.2.4.RELEASE.jar 也是最新版jar包 然后他就自动帮你添加整合MongoDB所有的jar包 包括驱动包

要是springMVC的jar 没导进来 在这可以添加

到此jar包依赖完成
