Class JsonObjectMapper

  • All Implemented Interfaces:
    com.fasterxml.jackson.core.Versioned, Serializable
    public class JsonObjectMapper
extends com.fasterxml.jackson.databind.ObjectMapper
    Pre-configured Jackson ObjectMapper with utility methods for JSON operations.

    This class extends Jackson's ObjectMapper with RocketRest-specific configuration and provides convenient static methods for common JSON serialization and deserialization tasks.

    Default Configuration

    • Field visibility: ANY (serializes private fields)
    • Getter/Setter visibility: NONE (ignores getters/setters)
    • Indented output: enabled
    • Unknown properties: ignored
    • Null values: excluded from output

    Object Serialization

    
 User user = new User("John", "john@example.com");

 // To JSON string (indented)
 String json = JsonObjectMapper.toJsonString(user);

 // To JSON string (compact)
 String compact = JsonObjectMapper.toJsonStringNoIdent(user);

    Object Deserialization

    
 String json = "{\"name\":\"John\",\"email\":\"john@example.com\"}";

 // To typed object
 User user = JsonObjectMapper.jsonToObject(json, User.class);

 // To Map
 Map<String, Object> map = JsonObjectMapper.jsonToMap(json);

 // To List of Maps
 String arrayJson = "[{\"id\":1},{\"id\":2}]";
 List<Map<String, Object>> list = JsonObjectMapper.jsonToListOfMap(arrayJson);

    JsonNode Operations

    
 JsonNode node = JsonObjectMapper.getJsonNode(json);
 String name = node.get("name").asText();

 Map<String, Object> map = JsonObjectMapper.jsonNodeToMap(node);

    Singleton Access

    
 // Get pre-configured singleton instance
 ObjectMapper mapper = JsonObjectMapper.get();

 // Get fresh default-configured mapper
 ObjectMapper fresh = JsonObjectMapper.getDefault();
