1.所需的包：

2.代碼：
(1)配置文件一：bootstrap.xml
<?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="org.springframework.data.mongodb.examples.hello"/> </beans>
(2)配置文件二：AppConfig.java(Spring通過配置一掃描注解得到)
@Configuration public class AppConfig { public @Bean MongoOperations mongoTemplate(Mongo mongo) { MongoTemplate mongoTemplate = new MongoTemplate(mongo, "test"); return mongoTemplate; } //用于創建Mongo實例 public @Bean MongoFactoryBean mongo() { MongoFactoryBean mongo = new MongoFactoryBean(); mongo.setHost("localhost"); return mongo; } public @Bean PersistenceExceptionTranslationPostProcessor persistenceExceptionTranslationPostProcessor() {return new PersistenceExceptionTranslationPostProcessor();} }
(3)main函數
ConfigurableApplicationContext context = new ClassPathXmlApplicationContext("META-INF/spring/bootstrap.xml");HelloMongo hello = context.getBean(HelloMongo.class);hello.run();System.out.println("DONE!");
(4)持久層：HelloMongo.java
@Repository public class HelloMongo { @Autowired MongoOperations mongoOperations; public void run() { if (mongoOperations.collectionExists(Person.class)) { mongoOperations.dropCollection(Person.class); } mongoOperations.createCollection(Person.class); Person p = new Person("John", 39); mongoOperations.insert(p); List<Person> results = mongoOperations.findAll(Person.class); System.out.println("Results: " + results); } }
(5)實體類：Person.java

類前使用@Document注解，id前使用@Id注解
