SSM中加入MongoDB配置

1.新建MongoDB的配置xml文件

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop"
	xmlns:tx="http://www.springframework.org/schema/tx" xmlns:util="http://www.springframework.org/schema/util"
	xmlns:context="http://www.springframework.org/schema/context"
	xmlns:mongo="http://www.springframework.org/schema/data/mongo"
	xsi:schemaLocation="
		 http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
		 http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd
		 http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd
		 http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util.xsd
		 http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd
		 http://www.springframework.org/schema/data/mongo http://www.springframework.org/schema/data/mongo/spring-mongo-1.8.xsd">

    <!-- 加载mongodb的属性配置文件 -->
   <!-- <context:property-placeholder location="mongodb-config.properties" ignore-unresolvable="true" />  -->

    <mongo:mongo-client id="mongo" host="${mongo.host}" port="${mongo.port}">
        <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:db-factory id="mongoDbFactory" dbname="${mongo.dbname}" mongo-ref="mongo" />

    <bean id="mongoTemplate" class="org.springframework.data.mongodb.core.MongoTemplate" lazy-init="false">
        <!-- <constructor-arg ref="mongo" />
        <constructor-arg name="databaseName" value="${mongo.dbname}" /> -->
        <constructor-arg name="mongoDbFactory" ref="mongoDbFactory"/>
    </bean>


    <!-- 映射转换器，扫描back-package目录下的文件，根据注释，把它们作为mongodb的一个collection的映射 -->
    <!--<mongo:mapping-converter base-package="jaky.web.*.dao" />-->
    <!-- mongodb bean的仓库目录，会自动扫描扩展了MongoRepository接口的接口进行注入 -->
    <!--<mongo:repositories base-package="jaky.web.*" />-->
</beans>

mongodb-config.xml文件新建成功。

2.新建MongoDB-config.properties

# MongoDB
# 做测试 可以先用下面这个数据库
mongo.host=localhost
mongo.dbname=test
#mongo.host=192.168.20.208
#mongo.dbname=unknown
mongo.port=27017
mongo.connectionsPerHost=8
mongo.threadsAllowedToBlockForConnectionMultiplier=4
#连接超时时间
mongo.connectTimeout=1000
#等待时间
mongo.maxWaitTime=1500
mongo.autoConnectRetry=true
mongo.socketKeepAlive=true
#Socket超时时间
mongo.socketTimeout=1500
mongo.slaveOk=true

mongo.host=localhost 连接的数据库地址ip

mongo.dbname=test  要连接的数据库

3.映入到配置文件中

在applicationContext.xml文件中映入刚才两个文件

   <!--对bean中的属性值进行外在化管理 -->
    <bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
        <property name="locations">
            <list>
                <value>classpath:common.properties</value>
                <value>classpath:mongodb-config.properties</value>
            </list>
        </property>

    </bean>

测试：

打开C:\Program Files\MongoDB\Server\3.6\bin mongod.exe 服务测试

后记：

学而不是则罔，思而不学则殆
