Jackson:如何使用带有@JsonAnySetter注释的自定义反序列化器？

@JsonDeserialize(using = CustomDeserializer.class)
public class CustomObject {
    // ...
}

public class CustomDeserializer implements JsonDeserializer<CustomObject> {
    @Override
    public CustomObject deserialize(JsonParser jsonParser, DeserializationContext deserializationContext) throws IOException, JsonProcessingException {
        CustomObject customObject = new CustomObject();
        
        // 获取根节点
        JsonNode rootNode = jsonParser.getCodec().readTree(jsonParser);
        
        // 遍历所有属性
        Iterator<Map.Entry<String, JsonNode>> fields = rootNode.fields();
        while (fields.hasNext()) {
            Map.Entry<String, JsonNode> field = fields.next();
            String fieldName = field.getKey();
            JsonNode fieldValue = field.getValue();
            
            // 使用@JsonAnySetter注释的方法将属性映射到Java对象上
            customObject.setUnknownProperty(fieldName, fieldValue);
        }
        
        return customObject;
    }
}

public class CustomObject {
    // ...
    
    @JsonAnySetter
    public void setUnknownProperty(String name, JsonNode value) {
        // 将未知属性映射到Java对象的字段或属性上
        // ...
    }
}
