接着[solr测试项目（上）–基于maven的springmvc环境搭建][solr_maven_springmvc]  
我们已经把一个简单的springmvc环境搭建好，下面我们开始整合spring-data-mongo。

# 整合spring-data-mongo #

参考[Ubuntu 14.04 LTS 安装 MongoDB][Ubuntu 14.04 LTS _ MongoDB]  
先将mongo数据库搭建好。

这里采用spring提供的MongoTemplate来操作。

## 依赖 ##

将spring和spring-data的版本采用bom管理起来

<properties>
        <spring-version>4.2.5.RELEASE</spring-version>
        <releasetrain-version>Hopper-SR3</releasetrain-version>
    </properties>
    <dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.springframework</groupId>
                <artifactId>spring-framework-bom</artifactId>
                <version>${spring-version}</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
            <dependency>
                <groupId>org.springframework.data</groupId>
                <artifactId>spring-data-releasetrain</artifactId>
                <version>${releasetrain-version}</version>
                <scope>import</scope>
                <type>pom</type>
            </dependency>
        </dependencies>
    </dependencyManagement>

最终的spring依赖和spring-data-mongodb和mongod的java驱动依赖如下

## 配置文件 ##

在src/main/resources/spring下建一个spring-dao.xml主要用来配置数据库的

**spring-dao.xml**

<?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:p="http://www.springframework.org/schema/p" xmlns:mongo="http://www.springframework.org/schema/data/mongo" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/data/mongo http://www.springframework.org/schema/data/mongo/spring-mongo.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">
        
        <context:property-placeholder location="classpath:mongo.properties" file-encoding="utf-8" 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="mylearn" mongo-ref="mongo" />
        
        <bean id="mongoTemplate" class="org.springframework.data.mongodb.core.MongoTemplate">
            <constructor-arg name="mongoDbFactory" ref="mongoDbFactory" />
        </bean>
    </beans>

在src/main/resources下建一个配置文件mongo.properties

**mongo.properties**

mongo.host=你的mongo数据库的地址
    mongo.port=27017
    mongo.connectionsPerHost=8
    mongo.threadsAllowedToBlockForConnectionMultiplier=4
    mongo.connectTimeout=1000
    mongo.maxWaitTime=1500
    mongo.socketKeepAlive=true
    mongo.socketTimeout=1500

**导入spring-dao.xml**  
在spring-core.xml中导入spring-dao.xml

## 测试 ##

测一下增删改查，其他的参考官方文档。

测试之前先把日志弄好
