我使用Spring（REST的API），我想擁有的POJO的JSON輸出小寫以下劃線代替駝峯：隱蔽首字母大寫小寫以下劃線春天
如： PhotoUpload：
package com.rh.dao.entity;
/**
*
* @author fabianlurz
*/
public class PhotoUpload {
private String imageUrl;
/**
* @return the imageUrl
*/
public String getImageUrl() {
return imageUrl;
}
/**
* @param imageUrl the imageUrl to set
*/
public void setImageUrl(String imageUrl) {
this.imageUrl = imageUrl;
}
}
所以IMAGEURL應該IMAGE_URL（也爲進入對象 - >映射）
有沒有一種方法來在全球擁有這個配置？ （不想使用JsonProperty註釋）

你是什麼意思與'擁有的POJO的小寫的輸出與underscore'？變量'imageUrl'的名稱更改爲'image_url'？如果是這樣。您應該避免使用[Oracle - 教程變量命名]（https://docs.oracle.com/javase/tutorial/java/nutsandbolts/variables.html#Naming）。 – SubOptimal
我的意思是Json輸出。 Sry說不清楚。我只想爲我的Json輸出使用另一種格式，然後是POJO原來的格式。所以imageUrl應該是Json輸出中的image_url。 –
