MongoDB整合Spring实例详细讲解(含代码)

时间：2021-10-17 15:59:17

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

MongoDB整合Spring实例详细讲解(含代码)

然后就开始我们开发之旅吧!

首先新建application.xml配置文件

    <property name="mongoTemplate" ref="mongoTemplate"></property>

然后编写操作mongodb的接口

再写对应接口的实现类：
