Question

Spring数据框架将数据插入错误的集合中。当我想要添加productPropertiesService.add(new ProductProperties(200,100));时，此记录会转到Product集合而不是ProductProperties集合。如何解决？

我的 applicationContext ：

...
  <bean id="mongoTemplate" class="org.springframework.data.mongodb.core.MongoTemplate">
        <constructor-arg name="mongoDbFactory" ref="mongoDbFactory"/>
    </bean>
    <bean id="mongoDbFactory"
          class="org.springframework.data.mongodb.core.SimpleMongoDbFactory">
        <constructor-arg name="mongo" ref="mongoFactoryBean" />
        <constructor-arg name="databaseName" value="test" />
    </bean>
    <bean id="mongoFactoryBean" class="org.springframework.data.mongodb.core.MongoFactoryBean">
        <property name="host" value="localhost" />
        <property name="port" value="27017"/>
    </bean>
    <bean class="org.springframework.dao.annotation.PersistenceExceptionTranslationPostProcessor" />
    <mongo:repositories base-package="ee.test.mongo.dao"/>
    <mongo:repositories base-package="mongodb"/>
    ...

测试插入的类：

public class MongoDBJDBC {

    public static void main( String args[] ){
ConfigurableApplicationContext context = new ClassPathXmlApplicationContext("spring/applicationContext.xml");

        ProductService productService = context.getBean(ProductService.class);
        ProductPropertiesService productPropertiesService = context.getBean(ProductPropertiesService.class);
        productPropertiesService.add(new ProductProperties(200,100));
        }
}

服务

@Service
            public class ProductPropertiesService {
                @Autowired
                private ProductPropertiesDao productPropertiesDao;

                public void add(ProductProperties productProperties) {
                    productPropertiesDao.save(productProperties);
                }
             }

存储库：

@Repository
            public class ProductPropertiesDao {

                @Autowired
                private MongoOperations mongoOperations;

                public void save(ProductProperties productProperties) {
                    mongoOperations.save(productProperties);
                }

更新实体类：

@Document(collection = ProductProperties.COLLECTION_NAME)
public class ProductProperties implements Serializable {

    public static final String COLLECTION_NAME = "product_properties";
    @Id
    private String id;
    private String property;
    ...
  }

问题已解决，但作为一种奇怪的副作用，文档被添加到正确的集合中，但添加了额外的字段"_class" : "ee.test.mongo.model.ProductProperties"。如何解决？
