java jackson 将对象转json时，忽略子对象的某个属性

//父对象

public class user implements java.io.Serializable {

@JsonIgnoreProperties(value={"addressId"})//在解析成json时，忽略子属性的addressId字段

private Address address;

private String username;

//.........

}

//子对象

public class Address  implements java.io.Serializable {

private int addressId;

private String address;

private String phone;

//..........

}

//注：当对象是hibernate查出来的代理对象时，一对多对象会给子对象注入handler和hibernateLazyInitializer属性，如果给jackson解析就会报错

//在一对多或多对一字段前加上@JsonIgnoreProperties(value={"handler","hibernateLazyInitializer"})即可
