MongoDB是面向檔案的非關系型資料庫，資料模型是一種類似于JSON的結構，在資料庫中存的是各種各樣的JSON，官網下載地址：https://www.mongodb.com/download-center/enterprise
一、以Centos為例，安裝mongoDB
1）下載安裝包mongodb-linux-x86_64-rhel70-4.2.1.tgz，上傳opt目錄
2）解壓安裝包 tar -zxvf mongodb-linux-x86_64-rhel70-4.2.1.tgz
3）mv mongodb-linux-x86_64-rhel70-4.2.1/ /usr/local/mongodb
4）在bin目錄，新增mongodb.conf組態檔
dbpath = /data/db #資料檔案存放目錄，提前新建目錄 logpath = /data/logs/mongodb.log #日志檔案存放目錄，提前新建目錄 port = 27017 #埠fork = true #以守護程式的方式啟用，即在后臺運行bind_ip=0.0.0.0 #允許所有的連接auth=true #是否安全檢驗
5）運行服務
./mongod --config mongodb.conf
二、創建資料庫與用戶
1）修改配置引數，重啟服務
auth=false #是否安全檢驗
2）登錄服務，跳過權限驗證，創建應用資料庫與用戶，新增成功以后，改回安全校驗模式，
2.1）切換資料庫 use cmp; 創建用戶 2.2）db.createUser({user:"cmp",pwd:"123456",roles:[{role:"dbAdmin",db:"cmp"},{role:"readWrite",db:"cmp"}]}); 
3）使用NoSQLBooster客戶端登錄
三、Spring整合MongoDB
1）引入MongoDB的pom檔案
<?xml version="1.0" encoding="UTF-8"?><project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.demo</groupId> <artifactId>springmongodb</artifactId> <version>1.0-SNAPSHOT</version> <name>springmongodb</name> <url>http://www.example.com</url> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <maven.compiler.source>1.7</maven.compiler.source> <maven.compiler.target>1.7</maven.compiler.target> </properties> <dependencies> <dependency> <groupId>org.springframework.data</groupId> <artifactId>spring-data-mongodb</artifactId> <version>1.8.6.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-test</artifactId> <version>4.1.9.RELEASE</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-log4j12</artifactId> <version>1.7.25</version> </dependency> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.12</version> <scope>test</scope> </dependency> </dependencies></project>
2）Spring組態檔
mongodb.properties
mongodb.hostport=服務IP埠mongodb.db=mongodb.username=mongodb.password=
spring-mongodb.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:context="http://www.springframework.org/schema/context" xmlns:mongo="http://www.springframework.org/schema/data/mongo" xsi:schemaLocation=" http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.2.xsd http://www.springframework.org/schema/data/mongo http://www.springframework.org/schema/data/mongo/spring-mongo-1.0.xsd http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.2.xsd"> <context:property-placeholder location="classpath:mongodb.properties" /> <context:component-scan base-package="com.itep"></context:component-scan> <!-- 定義mongo物件，對應的是mongodb官方jar包中的Mongo，replica-set設定集群副本的ip地址和埠 --> <mongo:mongo id="mongo" replica-set="${mongodb.hostport}"> <!-- 一些連接屬性的設定 --> <mongo:options connections-per-host="8" threads-allowed-to-block-for-connection-multiplier="4" connect-timeout="20000" max-wait-time="20000" auto-connect-retry="true" socket-keep-alive="true" socket-timeout="20000" slave-ok="true" write-number="1" write-timeout="0" write-fsync="true" /> </mongo:mongo> <mongo:repositories base-package="com.itep.dao"></mongo:repositories> <mongo:db-factory dbname="${mongodb.db}" mongo-ref="mongo"/> <!-- 配置用戶名密碼 --> <bean id="userCredentials" > <constructor-arg name="username" value="https://www.cnblogs.com/walkwithmonth/p/${mongodb.username}" /> <constructor-arg name="password" value="https://www.cnblogs.com/walkwithmonth/p/${mongodb.password}" /> </bean> <bean id="mongoTemplate" > <constructor-arg ref="mongo" /> <constructor-arg ref="userCredentials" /> <constructor-arg name="databaseName" value="https://www.cnblogs.com/walkwithmonth/p/${mongodb.db}" /> </bean></beans>3）編碼
