我定义了以下类
@JsonTypeName("PhotoSetUpdater")
public class PhotoSetUpdater {
@JsonProperty("Title")
private String title;
@JsonProperty("Caption")
private String caption;
@JsonProperty("Keywords")
private String[] keywords;
@JsonProperty("Categories")
private int[] categories;
@JsonProperty("CustomReference")
private String customReference; // new in version 1.1
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
public String getCaption() {
return caption;
}
public void setCaption(String caption) {
this.caption = caption;
}
public String getCustomReference() {
return customReference;
}
public void setCustomReference(String customReference) {
this.customReference = customReference;
}
public void setKeywords(String[] keywords) {
this.keywords = keywords;
}
public String[] getKeywords() {
return keywords;
}
public void setCategories(int[] categories) {
this.categories = categories;
}
public int[] getCategories() {
return categories;
}
}
问题是,在我用 Jackson JSON 序列化程序序列化这个类之后,这些字段在结果负载中插入了两次:一个以小写字母开头,一个以大写字母开头:
... {“标题”:“aa”,“标题”:“aa”,...}
类型定义可能有什么问题?
