spring和mongo的集成

1spring和mong集成需要的jar包 

   spring-data-commons-core-1.2.1.RELEASE.jar

   spring-data-mongodb-1.0.4.RELEASE.jar

   mongo-2.10.1.jar

 

2 web.xml配置,classpath*:会自动读取ClassPath路径下面所有文件

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
id="WebApp_ID" version="3.0">
<display-name>cms_service</display-name>

<!-- ContextParam Config -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath*:applicationContext*.xml</param-value>
</context-param>

</web-app>

3 applicationContext-mongodb.xml的配置

<?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:mongo="http://www.springframework.org/schema/data/mongo"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.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.db.host}">
<mongo:options connections-per-host="10"
threads-allowed-to-block-for-connection-multiplier="5"
connect-timeout="10000" max-wait-time="120000"
auto-connect-retry="true"
max-auto-connect-retry-time="0" socket-keep-alive="false"
socket-timeout="0" write-number="1"
write-timeout="0" write-fsync="true" slave-ok="true" />
</mongo:mongo>


<mongo:db-factory dbname="${mongo.db.name}" mongo-ref="mongo"
username="${mongo.db.username}" password="${mongo.db.password}" />


<bean id="mongoOperations" class="org.springframework.data.mongodb.core.MongoTemplate">
<constructor-arg name="mongoDbFactory" ref="mongoDbFactory" />
</bean>

<bean id="mongodbDao" class="com.whty.aam.common.mongo.MongodbDao">
  <property name="mongoOperations" ref="mongoOperations"/>
</bean>

 

</beans>

4 由于都是${}的形式，是因为applicationContext.xml中配置了

  <bean id="propertyConfigurer"
class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="location">
<value>classpath:sysconfig.properties</value>
</property>
</bean>

该properties文件里面是

mongo.db.name=tycms_m
mongo.db.username=
mongo.db.password=
mongo.db.host=127.0.30.26:30000
#mongo.db.host=127.0.212.41:22000
mongo.connectionsPerHost=10
mongo.threadsAllowedToBlockForConnectionMultiplier=5
mongo.connectTimeout=10000
mongo.maxWaitTime=120000
mongo.autoConnectRetry=true
mongo.socketKeepAlive=false
mongo.socketTimeout=0

5 java操作mongo,使用如下

public class MongodbDao {

public MongoOperations mongoOperations;

public <T extends BaseDomain> void insert(T entity) {
Date date = new Date(); // 创建时间
entity.setCreateTime(date);
entity.setUpdateTime(date);
entity.setCreateTimeStr(DateUtils.dateToStrLong(date));
entity.setUpdateTimeStr(DateUtils.dateToStrLong(date));
mongoOperations.insert(entity);
}

}
