Example for Annotation @MappingTable with HashMap

A HashMap cannot be defined directly in an annotation.

The following example is NOT possible:

public static Map<Object, Object> salutationMap = new HashMap<>() {{
    put("1", "MALE");
    put("2", "FEMALE");
    put("3", "DIVERS");
}};

@MappingTable(map = salutationMap)
private MappingValue<String> salutation;

A HashMap can be used with Enum, Class or nested Annotation:

• Example with Enum
• Example with Class
• Example with nested Annotation
