【JSON 注解】JSON循环引用1-----Jackson常用注解介绍 eq:@JsonIgnore

2022-10-31 21:18:58

循环引用：实体A与实体B有关系，A中有B作为字段，B中有A作为一个字段。查询A对象后，将A对象转化为JSON格式数据时，会因为序列化过程中导致A中有B字段，B字段中又有A，这样就引起了循环引用的问题！！

即如下的解释：

如果A对象持有B的引用，B对象持有A的引用，这样就形成了循环引用，如果直接使用json-lib转换，会报错：

net.sf.json.JSONException: There is a cycle in the hierarchy!

错误由来：

maven搭建的项目使用spring+hibernate+springMVC

两个实体类： Product产品类：Disease疾病类（1：n）关系

发现错误依旧存在，经查询，是因为：

是转json时候死循环的问题。需要用jackson注解@jsonignore，

然后就像上面的Disease实体类中所写，

 private static final long serialVersionUID = 1L;

     private String diseaseId;

     @JsonIgnore

     private Product product;

     private String diseaseName;

     private String diseasePath;

     private Integer diseaseOrder;

     private String diseaseCre;

将@jsonignore注解加载Product这个属性上。

就可以解决问题了！！

但是这样仅仅解决了可以查询Disease实体类的问题，如果要将实体类转化为JSON格式的数据传递给前台，就会报错！！！！下一篇JSON循环引用2 解决这个问题！！

下面将借鉴来的文章贴下：

一般情况下使用JSON只使用了java对象与字符串的转换，但是，开发APP时候，我们经常使用实体类来做转换；这样，就需要用到注解；

Jackson默认是针对get方法来生成JSON字符串的，可以使用注解来做一些特殊用途；常见的使用如下：

1 排除属性

@JsonIgnore，一般标记在属性或方法上；作用于序列化与反序列化；

@JsonIgnoreProperties，如果是代理类，由于无法标记在属性或方法上，所以，可以标记在类声明上；也作用于反序列化时的字段解析；

2 属性别名

@JsonProperty，序列化/反序列化都有效；

3 属性排序

@JsonPropertyOrder，注释在类声明中；

4 属性格式转换

使用自定义序列化/反序列化来处理；

@JsonSerialize，序列化；

@JsonDeserialize，反序列化；

注意：在使用hibernate的时候，查询数据库后产生的实体类是个代理类，这时候转换JSON会报错；

解决方法有两种：

1）设置FAIL_ON_EMPTY_BEANS属性，告诉Jackson空对象不要抛异常；

mapper.disable(SerializationConfig.Feature.FAIL_ON_EMPTY_BEANS);

2）使用@JsonIgnoreProperties注解

在实体类声明处加上@JsonIgnoreProperties(value = {"hibernateLazyInitializer", "handler"})注解；

建议使用@JsonIgnoreProperties注解，这样生成的JSON中不会产生多余的字段；

5 父/子关联

@JsonManagedReference，放在父亲类中；

@JsonBackReference，放在孩子类中；

6 去掉包装

@JsonUnwrapped，意思如下：

Ability to map JSON like

{

"name" : "home",

"latitude" : 127,

"longitude" : 345

}

to classes defined as:

class Place {

public String name;

@JsonUnwrapped

public Location location;

}

class Location {

public int latitude, longitude;

}
