方法详细资料

getBackwardsCompatibleJsonSchemaInfo

public SchemaInfo getBackwardsCompatibleJsonSchemaInfo()

Implemented for backwards compatibility reasons. since the original schema generated by JSONSchema was based off the json schema standard since then we have standardized on Avro

返回:

of

public static <T> JSONSchema<T> of(SchemaDefinition<T> schemaDefinition)

of

public static <T> JSONSchema<T> of(Class<T> pojo)

of

public static <T> JSONSchema<T> of(Class<T> pojo,
 Map<String,String> properties)

clearCaches

public static void clearCaches()

Clears the caches tied to the ObjectMapper instances and replaces the singleton ObjectMapper instance. This can be used in tests to ensure that classloaders and class references don't leak across tests.
