I have a class that I want to deserialize to:

@Data
public class Config 

 private Map<String, Item> items;


@Data
public class Item 

 private String a;
 private String b;
 private String c;

JSON string:

 "item1": 
 "a": "1",
 "b": "2",
 "c": "3"
 ,
 "item2": 
 "a": "10",
 "b": "20",
 "c": "30"
 ,
 "item3": 
 "a": "5",
 "b": "6",
 "c": "7"
 

What should I use to deserialize the JSON string into Config?

EDIT: Added more items to JSON

UPDATE

Use JsonAlias to get multiple values in single property:

@JsonAlias("item1", "item2", "item3")
private Map<String, Item> items;

Annotation that can be used to define one or more alternative names for a property

Older answer to old question

Add JsonProperty with name item1

@Data
public class Config 
 @JsonProperty("item1")
 private Map<String, Item> items;

Marker annotation that can be used to define a non-static method as a "setter" or "getter" for a logical property (depending on its signature), or non-static object field to be used (serialized, deserialized) as a logical property.

EDIT

Updated as Map following @michaeak comment

A coworker helped me with this answer to my question:

@Data
public class Config 

 private Map<String, Item> items;

 @JsonAnyGetter
 public Map<String, Item> getItems() 
 return items;
 

 @JsonAnySetter
 public void setItem(final String key, final Item value) 
 items.put(key, value);
 


@Data
public class Item 

 private String a;
 private String b;
 private String c;
