Enums having uri-reference format won't compile in Java

[pasinski]

I created a simple api spec, where one field is enum and has a uri-reference format.

source:
            type: string
            format: uri-reference
            minLength: 1
            enum:
              - com.example

Such field will get generated in Java as public static enum Source { com.example }. Since com.example is not a valid enum identifier in Java, the code will not compile.

In this case, a valid approach would be to generate a class as follows (see also enum generation in https://github.com/asyncapi/java-spring-template):

public enum Source {
            
        COM_EXAMPLE(String.valueOf("com.example"));
            
        private String value;

        Source (String v) {
            value = v;
        }

        public String value() {
            return value;
        }

        @Override
        @JsonValue
        public String toString() {
            return String.valueOf(value);
        }

        @JsonCreator
        public static SourceEnum fromValue(String value) {
            for ( SourceEnum b :  SourceEnum.values()) {
                if (Objects.equals(b.value, value)) {
                    return b;
                }
            }
            throw new IllegalArgumentException("Unexpected value '" + value + "'");
        }
    }

of course, @JsonValue can also be placed on value() method
