泽西岛忽略杰克逊的注解
[英]Jersey ignoring Jackson annotations
问题描述
I'm working on a Java project that uses Jersey and Jackson to convert Java objects to JSON. 
我正在开发一个使用Jersey和Jackson将Java对象转换为JSON的Java项目。 A few days ago I noticed that using com.fasterxml.jackson.annotation.JsonProperty to try to change the name of a JSON property had no effect. 几天前，我注意到使用com.fasterxml.jackson.annotation.JsonProperty尝试更改JSON属性的名称无效。 This issue wasn't that big so I ignored it. 这个问题并不大，所以我忽略了它。 Today I created a JPA relationship between to @Entity POJOs. 今天，我在@Entity POJO之间创建了JPA关系。 The relationship was @OneToMany and @ManyToOne . 关系是@OneToMany和@ManyToOne 。 One of the POJOs was being converted to JSON which created an infinite recursion (StackOverflowError). 其中一个POJO被转换为JSON，从而创建了无限递归（StackOverflowError）。 I attached a com.fasterxml.jackson.annotation.JsonIgnore annotation to one of the fields but like before this annotation was ignored. 我将com.fasterxml.jackson.annotation.JsonIgnore批注附加到其中一个字段，但就像在忽略此批注之前一样。 I've supplied excerpts of my pom.xml which I thought would be relevant based off of this answer to a related question. 我提供了我的pom.xml摘录，基于对一个相关问题的回答 ，我认为这是有意义的。

This is the offending class: 这是令人反感的类：
@Entity
@Table(name = "PAGE")
@XmlRootElement
public class Page implements Serializable {
//... Id and other fields here
@JsonIgnore
@OneToMany(fetch = LAZY, mappedBy = "page")
private Set<Activity> analyticsActivity;
}

A time ago I have the same problem annotation JsonIgnoreProperties is used on class scope. 前一段时间，我在类范围上使用了相同的问题注释JsonIgnoreProperties。 On jackson when you want ignore some field you need specify the field name. 在杰克逊上，当您要忽略某些字段时，需要指定字段名称。
@JsonIgnoreProperties(ignoreUnknown = true, value= {"prev", "next"})
public class Model implements Serializable {
private Model prev;
private Model next; ....
Jackson Ignore Annotations example 杰克逊忽略注释示例
To prevent "an infinite recursion (StackOverflowError)" make sure you dont have any reference, method calling a inside member, to prevent that you can ignore this fields too. 为防止发生“无限递归（StackOverflowError）”，请确保您没有任何引用（调用内部成员的方法），以防止您也忽略此字段。 An example of "an infinite recursion (StackOverflowError)" “无限递归（StackOverflowError）”的示例
public class Model implements Serializable {
private Model prev; // reference previous model
private Model next; // reference next model
this type of data structure cause infinite recursion because always Jackson get prev or next field and get again and again and again. 这种类型的数据结构会导致无限递归，因为杰克逊总是获得上一个或下一个字段，并且一次又一次地获取。

The solution I found to this issue may unfortunately have nothing even to do with Jackson or Jersey. 不幸的是，我找到的解决方案甚至与杰克逊或泽西岛也没有任何关系。 As someone stated "This is so unnecessary, confusing, and makes it difficult to figure out what is actually being used for for what." 正如某人所说：“这是不必要的，令人困惑的，并且使弄清楚实际用于什么用途变得困难。” In my question I did not share the entire 174 dependency long pom.xml so it would've been impossible for anyone to answer this question. 在我的问题中，我没有共享整个174个依赖项长的pom.xml，因此任何人都不可能回答这个问题。 I hope someone finds this useful though. 我希望有人会觉得有用。
When I added @XmlTransient to the field it made no positive difference. 当我将@XmlTransient添加到该字段时，没有任何积极的区别。 When I added it to the getter and the field I was able to hide the analyticsActivity from the produced JSON. 当我将其添加到getter和字段中时，我能够从生成的JSON中隐藏analyticsActivity 。 I did not test if adding @XmlTransient to the getter alone is effective. 我没有测试仅将@XmlTransient添加到吸气剂是否有效。
import javax.xml.bind.annotation.XmlTransient;
@Entity
@Table(name = "PAGE")
@XmlRootElement
public class Page implements Serializable {
//... Id and other fields here
@XmlTransient
@OneToMany(fetch = LAZY, mappedBy = "page")
private Set<Activity> analyticsActivity;
@XmlTransient
public Set<TmptREPDeskAnalytics> getAnalyticsActivity() {
return analyticsActivity;
}
}
