java jackson 将对象转json时，忽略子对象的某个属性

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;

//.........

}

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
