disconf-基于xml分布式配置管理mongo

mongodb目前有3种部署方式：单机、副本集（replica set）、分片（shard），本文结合disconf介绍这3种部署方式该如何和disconf配合使用

单机版本
a. 在resources文件夹下新建mongo-single.properties，内容为：

# mongo
mongo.db.name=xxxdb
mongo.host=localhost
mongo.port=27017
mongo.connectionsPerHost=8
mongo.threadsAllowedToBlockForConnectionMultiplier=4
mongo.connectTimeout=5000
mongo.maxWaitTime=15000
mongo.autoConnectRetry=true
mongo.socketKeepAlive=false
mongo.socketTimeout=5000
mongo.slaveOk=false

b.在resources文件夹下新建mongo-single.xml，内容为：

<?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:util="http://www.springframework.org/schema/util" 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-3.1.xsd
            http://www.springframework.org/schema/context
            http://www.springframework.org/schema/context/spring-context.xsd
            http://www.springframework.org/schema/util
            http://www.springframework.org/schema/util/spring-util-3.0.xsd
            http://www.springframework.org/schema/data/mongo
            http://www.springframework.org/schema/data/mongo/spring-mongo-1.0.xsd">

  <mongo:mongo host="${mongo.host}" port="${mongo.port}">
    <mongo:options connections-per-host="${mongo.connectionsPerHost}"
      threads-allowed-to-block-for-connection-multiplier="${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:db-factory dbname="${mongo.db.name}" mongo-ref="mongo" />
  <bean id="mongoTemplate" class="org.springframework.data.mongodb.core.MongoTemplate">
    <constructor-arg name="mongoDbFactory" ref="mongoDbFactory" />
  </bean>
</beans>

主要是配置了一个mongoTemplate bean提供mongo crud的api封装接口，使用时只要注入该bean就可以，主要用的是spring data mongo

副本集
创建mongo-replset.properties，内容为：

# mongo
mongo.db.name=xxxdb
mongo.replset=ip1:27017,ip1:27018,ip1:27019
mongo.connectionsPerHost=8
mongo.threadsAllowedToBlockForConnectionMultiplier=4
mongo.connectTimeout=5000
mongo.maxWaitTime=15000
mongo.autoConnectRetry=true
mongo.socketKeepAlive=false
mongo.socketTimeout=5000
mongo.slaveOk=true

主要是指定了replset，将slaveOk设置为true表示从节点是可以接受读请求（默认是不可以的，必须从client端进行设置）
创建mongo-replset.xml，内容为：

<?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:util="http://www.springframework.org/schema/util" 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-3.1.xsd
            http://www.springframework.org/schema/context
            http://www.springframework.org/schema/context/spring-context.xsd
            http://www.springframework.org/schema/util
            http://www.springframework.org/schema/util/spring-util-3.0.xsd
            http://www.springframework.org/schema/data/mongo
            http://www.springframework.org/schema/data/mongo/spring-mongo-1.0.xsd">

  <mongo:mongo id="mongo" replica-set="${mongo.replset}">
    <mongo:options connections-per-host="${mongo.connectionsPerHost}"
       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:db-factory dbname="${mongo.db.name}" mongo-ref="mongo" />
  <bean id="mongoTemplate" class="org.springframework.data.mongodb.core.MongoTemplate">
    <constructor-arg name="mongoDbFactory" ref="mongoDbFactory" />
  </bean>
</beans>

使用方法同单机

分片
新建mongo-shard.properties，内容为：

# mongo
mongo.db.name=sparta
mongo.host=ip
mongo.port=27117
mongo.connectionsPerHost=8
mongo.threadsAllowedToBlockForConnectionMultiplier=4
mongo.connectTimeout=5000
mongo.maxWaitTime=15000
mongo.autoConnectRetry=true
mongo.socketKeepAlive=false
mongo.socketTimeout=5000
mongo.slaveOk=false

这里的ip和port需要指定的是mogos（当然mongos也可以建立副本集）进程的ip和端口，由mongos负责分发请求到每个不同的分片
新建mongo-shard.xml，内容为：

<?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:util="http://www.springframework.org/schema/util" 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-3.1.xsd
            http://www.springframework.org/schema/context
            http://www.springframework.org/schema/context/spring-context.xsd
            http://www.springframework.org/schema/util
            http://www.springframework.org/schema/util/spring-util-3.0.xsd
            http://www.springframework.org/schema/data/mongo
            http://www.springframework.org/schema/data/mongo/spring-mongo-1.0.xsd">

  <mongo:mongo host="${mongo.host}" port="${mongo.port}">
    <mongo:options connections-per-host="${mongo.connectionsPerHost}"
      threads-allowed-to-block-for-connection-multiplier="${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:db-factory dbname="${mongo.db.name}" mongo-ref="mongo" />
  <bean id="mongoTemplate" class="org.springframework.data.mongodb.core.MongoTemplate">
    <constructor-arg name="mongoDbFactory" ref="mongoDbFactory" />
  </bean>
</beans>

基于上述配置可以将mongo和disconf配置使用，让disconf来管理mongo的配置文件
