Json KEY不断变化时对Java对象的Spring响应

public class MyObject {
    @JsonAlias({"key1", "key2", "key3"})
    private String myProperty;
    // getter and setter
}

public class MyObjectDeserializer extends JsonDeserializer<MyObject> {
    @Override
    public MyObject deserialize(JsonParser jsonParser, DeserializationContext deserializationContext) throws IOException {
        ObjectNode node = jsonParser.getCodec().readTree(jsonParser);
        String myProperty = null;
        if (node.has("key1")) {
            myProperty = node.get("key1").asText();
        } else if (node.has("key2")) {
            myProperty = node.get("key2").asText();
        } else if (node.has("key3")) {
            myProperty = node.get("key3").asText();
        }
        MyObject myObject = new MyObject();
        myObject.setMyProperty(myProperty);
        return myObject;
    }
}

@JsonDeserialize(using = MyObjectDeserializer.class)
public class MyObject {
    private String myProperty;
    // getter and setter
}

public ResponseEntity<Map<String, Object>> handleJsonResponse(@RequestBody Map<String, Object> json) {
    // 处理Json数据
    // ...
    return ResponseEntity.ok(json);
}
