杰克逊注释

本文介绍了杰克逊注释 - 如何重命名元素名称？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

什么是杰克逊JSON注解的方式当量为以下JAX-B注解？

我需要产生JSON，而不是XML和需要知道在JAX-B等价表示常规杰克逊注释。

重命名域。

使用getter方法​​，而不是领域。

这些功能如果JSON / XML元素名称是一个java的保留字特别重要像新，公共，静态 等。

所以，我们必须命名POJO领域_new_，_public_，_static_等，分别为

但使用JAX-B注释它们重命名回新，公，静等在生成的XML（和JSON）的元素。

重命名字段

@XmlAccessorType（XmlAccessType.FIELD）公共类Person {    @XmlElement（必填= TRUE）    受保护的字符串名称;    @XmlElement（必填= TRUE）    受保护的字符串地址;    @XmlElement（NAME =包工头）    保护布尔_restricted_;    @XmlElement（NAME =新）    保护布尔_new_;}

重定向到使用属性的getter （我觉得这是它是如何在JAX-B完成）

@XmlAccessorType（XmlAccessType.PROPERTY）公共类Person {    受保护的字符串名称;    受保护的字符串地址;    保护布尔_restricted_;    保护布尔_new_;    @XmlElement（必填= TRUE）    保护字符串的getName（）{返回名称;}    @XmlElement（必填= TRUE）    保护字符串的getAddress（）{返回地址;}    @XmlElement（NAME =包工头）    保护布尔getRestricted（）{返回_restricted_;}    @XmlElement（NAME =新）    保护布尔GETNEW（）{返回_new_;}}

解决方案

也许这是一个有点晚了，但无论如何..

您可以重命名一个属性只是添加

@JsonProperty（承包人）

和默认杰克逊使用getter和setter序列化和反序列化。

What is the equiv way in Jackson json annotation for the following jax-b annotations?

I need to produce json rather than xml and need to know the conventional jackson annotations that is equivalently denoted in jax-b.

rename a field.

use getters instead of fields.

These features are especially crucial if the json/xml element name is a java reserved word like "new", "public", "static", etc.

So that we have to name the POJO fields as "_new_", "_public_", "_static_", etc, respectively,

but use jax-b annotation to rename them back to "new", "public", "static", etc in the generated XML (and json) elements.

Renaming a field

@XmlAccessorType(XmlAccessType.FIELD) public class Person{ @XmlElement(required = true) protected String name; @XmlElement(required = true) protected String address; @XmlElement(name = "contractor") protected boolean _restricted_ ; @XmlElement(name = "new") protected boolean _new_ ; }

Redirect to using property getter (I think this is how it is done in jax-b)

@XmlAccessorType(XmlAccessType.PROPERTY) public class Person{ protected String name; protected String address; protected boolean _restricted_ ; protected boolean _new_ ; @XmlElement(required = true) protected String getName() {return name;} @XmlElement(required = true) protected String getAddress() {return address;} @XmlElement(name = "contractor") protected boolean getRestricted() {return _restricted_;} @XmlElement(name = "new") protected boolean getNew(){return _new_;} }

解决方案

Probably it's a bit late but anyway..

you can rename a property just adding

@JsonProperty("contractor")

And by default Jackson use the getter and setter to serialize and deserialize.
