@Id - 配置id

@Document  映射到数据库的集合名，可以设置名称

@DBRef - applied at the field to indicate it is to be stored using a com.mongodb.DBRef.

@Indexed - applied at the field level to describe how to index the field.

@CompoundIndex - applied at the type level to declare Compound Indexes

@GeoSpatialIndexed - applied at the field level to describe how to geoindex the field.

@Transient - 当有数据部需要保存的时候可以使用

@PersistenceConstructor - marks a given constructor - even a package protected one - to use when instantiating the object from the database. Constructor arguments are mapped by name to the key values in the retrieved DBObject.

@Value - this annotation is part of the Spring Framework . Within the mapping framework it can be applied to constructor arguments. This lets you use a Spring Expression Language statement to transform a key's value retrieved in the database before it is used to construct a domain object.

@Field - 给该属性添加存储在数据库中的名字

@Document@CompoundIndexes({@CompoundIndex(name ="age_idx",def="{'lastName': 1, 'age': -1}")})

//上面配置了联合属性lastName和agepublicclassPerson<T extendsAddress>{

@IdprivateString id;

@Indexed(unique =true)privateInteger ssn;

@Field("fName")privateString firstName;

@IndexedprivateString lastName;

privateInteger age;

@TransientprivateInteger accountTotal;

@DBRefprivateList<Account> accounts;

private T address;

publicPerson(Integer ssn){this.ssn = ssn;}

@PersistenceConstructorpublicPerson(Integer ssn,String firstName,String lastName,Integer age, T address){this.ssn = ssn;this.firstName = firstName;this.lastName = lastName;this.age = age;this.address = address;}}
