Hi there,
maybe I have an regression issue with Jackson 2.10.. but maybe I doing
something wrong... hope you can help me out.
A simple Test shows the problem. We having a class like this:
@JsonTypeInfo(
use = JsonTypeInfo.Id.MINIMAL_CLASS,
include = JsonTypeInfo.As.PROPERTY,
property = "@class"
)
public class EnumContaintingClass <ENUM_TYPE extends Enum<ENUM_TYPE>> {
private ENUM_TYPE selected;
private List<ENUM_TYPE> options;
public EnumContaintingClass(){
}
public EnumContaintingClass(ENUM_TYPE selected, Class<ENUM_TYPE> cls) {
this.selected = selected;
readOptionsFromEnum(cls);
}
private void readOptionsFromEnum(Class < ENUM_TYPE > enumClass) {
ENUM_TYPE[] enumConstants = enumClass.getEnumConstants();
options = Arrays.asList(enumConstants);
}
// getter and setter here..
}
And a Test for a roundtrip:
public class JacksonTestCase {
public enum TestEnum { FIRST, SECOND, THIRD; }
@Test
public void serialize() throws IOException {
EnumContaintingClass gui = new EnumContaintingClass(TestEnum.SECOND,
TestEnum.class);
ObjectMapper mapper = new ObjectMapper();
String str = mapper.writer().writeValueAsString(gui);
Object o = mapper.readerFor(EnumContaintingClass.class).readValue(str);
Assert.assertNotNull(o);
}
}
Serializing works fine but deserzializing fails with
*Cannot deserialize Class java.lang.Enum (of type enum) as a Bean*
This testcase works fine with the latest 2.9 Jackson but with 2.10 it fails.
I tried to add the TypeInfos also to the member but this didn't make it
works. The only thing I could do is changing from <ENUM_TYPE extends Enum<
ENUM_TYPE>> to <ENUM_TYPE>.
But that is not what we want to have, only Enums shall be allowed there (to
indicate this I added the readOptionsFromEnum-Method).
So please could you guide me how to make this work in Jackson 2.10 or is
this an regression issue?
