hjr-SQL-Mongotemplet配置和使用

現在properties配置

#本地mongodb
mongo.hostport=127.0.0.1:27017
mongo.host=127.0.0.1  
mongo.port=27017
mongo.username=
mongo.password=
mongo.database=xxx

在applicationContext.xml裏配置

<?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:context="http://www.springframework.org/schema/context"  
    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/context   
        http://www.springframework.org/schema/context/spring-context-3.0.xsd  
        http://www.springframework.org/schema/data/mongo  
        http://www.springframework.org/schema/data/mongo/spring-mongo-1.0.xsd">  
     <!-- 導入外部的properties文件 -->
     <context:property-placeholder location="classpath:application.properties"/>  

    <mongo:mongo id="mongo"  host="${mongo.host}" port="${mongo.port}"   />

     <bean id="userCredentials" class="org.springframework.data.authentication.UserCredentials">  
         <constructor-arg name="username"  value="${mongo.username}"/>  
         <constructor-arg name="password"  value="${mongo.password}"/>  
<!--         此處爲用戶名和密碼，默認爲空 -->
     </bean>  

     <bean id="mongoTemplate" class="org.springframework.data.mongodb.core.MongoTemplate">  
         <constructor-arg ref="mongo" />  
         <constructor-arg value="${mongo.database}" />  
         <constructor-arg ref="userCredentials" />  
     </bean>  
</beans>  

//獲取mongoTemplet實例
ApplicationContext ctx = new ClassPathXmlApplicationContext("applicationContext.xml");
    MongoOperations mongoTemplate = (MongoOperations) ctx.getBean("mongoTemplate");

或者直接寫class配置文件用註解初始化

@Configuration
public class MongoConfig extends AbstractMongoConfiguration {
//未實現方法
}

//獲取mongoTemplet實例
ApplicationContext ac = new AnnotationConfigApplicationContext(MongoConfig.class);  
MongoOperations mo = (MongoOperations)ac.getBean("mongoTemplate");  

操作
mongoTemplet.insert()
mongoTemplet.remove()
mongoTemplet.updata()
mongoTemplet.find()
