关于近几周使用MongoDB数据库的心得（小白宝典）

其他 2018-05-09 22:57:43 阅读次数: 0

最近因为项目需要，用到了MongoDB数据库，在此做一个总结；

1.安装MongoDB数据库：

当前所选MongoDB的版本为2.6.9

下载路径如下：http://dl.mongodb.org/dl/win32/x86_64

安装教程：https://jingyan.baidu.com/article/d5c4b52bef7268da560dc5f8.html

2.下载MongoDB的VUE可视化工具：

链接：https://pan.baidu.com/s/1slsRWC1 密码：6j2u

里面包含客户端以及破解版，破解版的图标文件替换客户端的即可；

上面两步做好之后，就可以使用了；

使用VUE要点：

这是我们连接本地时的框框，记住：用户名跟密码不用填，里面会有默认的admin库

其他的增删改查的方式可参看下面链接：http://blog.csdn.net/tuzongxun/article/details/50345161


3.关于MongoDB的整合Spring:

这是项目中用到的jar包，下载Spring和mongodb的相关依赖即可

这是整合spring和mongodb的applicationContext.xml文件

利用MongoTemplet进行增删改查

代码如下：

<?xml version="1.0" encoding="UTF-8"?>

   <context:component-scan base-package="com.tickets.*" />

    <mongo:mongo-client id="mongo" host="${mongo.host}" port="${mongo.port}" credentials="${mongo.user}:${mongo.pwd}@${mongo.defaultDbName}">
    
   <mongo:client-options
     connections-per-host="${mongo.connectionsPerHost}"
     threads-allowed-to-block-for-connection-multiplier="${mongo.threadsAllowedToBlockForConnectionMultiplier}"
     connect-timeout="${mongo.connectTimeout}"
     max-wait-time="${mongo.maxWaitTime}"
     socket-keep-alive="${mongo.socketKeepAlive}"
     socket-timeout="${mongo.socketTimeout}"
     /> 
   </mongo:mongo-client> 

    <!-- mongo的工厂，通过它来取得mongo实例,dbname为mongodb的数据库名，没有的话会自动创建 -->  
	<mongo:db-factory id="mongoDbFactory"
					  dbname="${mongo.DbName}"
	                  mongo-ref="mongo"/>

	<bean id="mappingContext"
        class="org.springframework.data.mongodb.core.mapping.MongoMappingContext" />
    <!-- 默认Mongodb类型映射 -->
    <bean id="defaultMongoTypeMapper"
        class="org.springframework.data.mongodb.core.convert.DefaultMongoTypeMapper">
        <constructor-arg name="typeKey">
            <null /><!-- 这里设置为空,可以把 spring data mongodb 多余保存的_class字段去掉 -->
        </constructor-arg>
    </bean>


    <bean id="mappingMongoConverter"
        class="org.springframework.data.mongodb.core.convert.MappingMongoConverter">
        <constructor-arg name="mongoDbFactory" ref="mongoDbFactory" />
        <constructor-arg name="mappingContext" ref="mappingContext" />
        <property name="typeMapper" ref="defaultMongoTypeMapper" />
    </bean>
    <!-- mongodb的主要操作对象，所有对mongodb的增删改查的操作都是通过它完成 -->  
    <bean id="mongoTemplate" class="org.springframework.data.mongodb.core.MongoTemplate">  
        <constructor-arg name="mongoDbFactory" ref="mongoDbFactory" />
        <constructor-arg name="mongoConverter" ref="mappingMongoConverter" /> 
    </bean>

</beans>

切记：获取配置资源用Mongo-client；里面也有连接用户名和密码的操作；

测试可用！

第一次写，写的不好请见谅；
