docker：二、（3） spring和spring-boot 对应mongo权限配置的不同

applicationContext-AppConfig.xml  内容

spring-boot 配置：

<!-- 引入配置文件 -->
<context:property-placeholder location="classpath:*.properties" />

<!-- mongo依赖 -->
<!-- 定义mongo对象，对应的是mongodb官方jar包中的Mongo，replica-set设置集群副本的ip地址和端口 -->
<mongo:mongo-client id="mongo" replica-set="${mongo.hostport}" credentials="${mongo.userPassDb}" >
<!-- 一些连接属性的设置 -->
<mongo:client-options connections-per-host="10"
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 dbname="leopard" mongo-ref="mongo"  />

<bean id="mongoTemplate" class="org.springframework.data.mongodb.core.MongoTemplate">
<constructor-arg ref="mongo" />
<constructor-arg name="databaseName" value="leopard" />
</bean>

配置文件内容
    application.properties

mongo.autoConnectRetry=true
mongo.connectTimeout=10000
mongo.connectionsPerHost=10
mongo.hostport=地址1\:端口,地址2\:端口?replicaSet\=mgset-4434465
mongo.maxWaitTime=1500
mongo.slaveOk=true
mongo.socketKeepAlive=true
mongo.socketTimeout=10000
mongo.threadsAllowedToBlockForConnectionMultiplier=4
mongo.userPassDb=用户名\:密码@数据库名

hostport ： 可配置多个mongo地址实现负载，  
    其中 replicaSet 参数为复制集，作用：使用N个mongo地址，自动容错，自动恢复，高可用
userPassDb ：mongo配置文件加入权限后，设置可访问的用户名和密码

常用 spring 配置：

<context:property-placeholder location="classpath:*.properties" />

<!-- mongo依赖 -->
<bean id="userCredentials" class="org.springframework.data.authentication.UserCredentials">
<constructor-arg   name="username" value="${mongo.userName}" />
<constructor-arg   name="password" value="${mongo.password}" />
</bean>
<!-- 定义mongo对象，对应的是mongodb官方jar包中的Mongo，replica-set设置集群副本的ip地址和端口 -->
<mongo:mongo id="mongo" replica-set="${mongo.hostport}">
<!-- 一些连接属性的设置 -->
<mongo:options connections-per-host="10"
threads-allowed-to-block-for-connection-multiplier="${mongo.threadsAllowedToBlockForConnectionMultiplier}"
connect-timeout="${mongo.connectTimeout}" max-wait-time="${mongo.maxWaitTime}"
auto-connect-retry="${mongo.autoConnectRetry}" socket-keep-alive="${mongo.socketKeepAlive}"
socket-timeout="${mongo.socketTimeout}" slave-ok="${mongo.slaveOk}"
write-number="1" write-timeout="0" write-fsync="true" />
</mongo:mongo>
<!-- 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 dbname="leopard" mongo-ref="mongo" />

<bean id="mongoTemplate" class="org.springframework.data.mongodb.core.MongoTemplate">
<constructor-arg ref="mongo" />
<constructor-arg name="databaseName" value="leopard" />
<constructor-arg ref="userCredentials" />
</bean>

配置文件内容
    mongo.properties

mongo.hostport=地址1\:端口,地址2\:端口?replicaSet\=mgset-4434465
mongo.connectionsPerHost=10
mongo.threadsAllowedToBlockForConnectionMultiplier=4
mongo.connectTimeout=10000
mongo.maxWaitTime=1500
mongo.autoConnectRetry=true
mongo.socketKeepAlive=true
mongo.socketTimeout=10000
mongo.slaveOk=true
mongo.userName=用户名
mongo.password=密码

与spring-boot相比较，只有 用户名、密码、数据库名、xml文件中前缀名，的引用有所不同

在拉取的  docker-compose 文件中加入 “ command: [--auth] ” 如下，便可开启权限限制version: '2'
services:
mongo:
# restart: always
image: mongo:3.2
command: [--auth]
ports:
- "37017:27017"
volumes:
- /data/db
