Spring Data之Mongodb初探

1、環境配置：     Mongodb安裝：     1）、下載            地址：http://www.mongodb.org/downloads     2）、安裝            安裝指南：http://docs.mongodb.org/manual/installation/            步驟：            在/data目錄下建立/data/mongodb/data、以及/data/mongodb/log目錄            解壓：tar -zxvf mongodb-linux-x86_64-2.2.2.tar            進入mongodb的bin的目錄下執行以下命令：            ./mongod --dbpath /data/mongodb/data --logpath /data/mongodb/log/mongo.log --logappend2、Spring data mongodb包下載      地址：http://s3.amazonaws.com/dist.springframework.org/release/SDMONGO/spring-data-mongo-1.1.0.RELEASE.zip      Spring data common jar包下載：      地址：http://s3.amazonaws.com/dist.springframework.org/milestone/DATACMNS/spring-data-commons-1.4.0.RC1.zip3、Mongodb的java驅動包下載：      地址：https://github.com/mongodb/mongo-java-driver/downloads4、所需jar包：      aopalliance-1.0.jar、asm-all-3.3.1.jar、cglib-2.2.2.jar、slf4j-api-1.7.1.jar、slf4j-log4j12-1.6.1.jar、slf4j-nop-1.5.8.jar、       commons-logging.jar、log4j-1.2.9.jar、Spring Framework  jar包、mongo-2.10.1.jar、Spring data mongodb的相關jar包、Spring data common的jar包5、建立Spring_mongodb java項目，將以上jar包匯入其中。     配置mongodb由Spring管理有兩種方法：    1）、使用@Configuration註解來進行配置：    這裡需要建立一個配置類，返回一個MongodbFactory對象、如：

@Configurationpublic class AppConfig {public @Bean MongoOperations mongoTemplate(Mongo mongo) {      MongoTemplate mongoTemplate = new MongoTemplate(mongo, "test");      return mongoTemplate;   }/*   * Factory bean that creates the Mongo instance   */   public @Bean MongoFactoryBean mongo() {       MongoFactoryBean mongo = new MongoFactoryBean();       mongo.setHost("localhost");       return mongo;   }/*   * Use this post processor to translate any MongoExceptions thrown in @Repository annotated classes   */   public @Bean PersistenceExceptionTranslationPostProcessor persistenceExceptionTranslationPostProcessor() {      return new PersistenceExceptionTranslationPostProcessor();   }}

2）、使用XML形式配置：

<?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"xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans-3.0.xsdhttp://www.springframework.org/schema/contexthttp://www.springframework.org/schema/context/spring-context-3.0.xsd"><context:annotation-config/><context:component-scan base-package="com.springdb.mongodb"><context:exclude-filter type="annotation" expression="org.springframework.context.annotation.Configuration"/></context:component-scan><bean id="mongoTemplate"><constructor-arg name="mongo" ref="mongo"/><constructor-arg name="databaseName" value="test"/></bean><!-- Factory bean that creates the Mongo instance --><bean id="mongo"><property name="host" value="192.168.130.170"/><property name="port" value="27017"/></bean><!-- Use this post processor to translate any MongoExceptions thrown in @Repository annotated classes --><bean/></beans>
