Thank you for reporting this issue: I was able to reproduce it with a simplified example. Also does not seem to fail for 2.9. I suspect this may be related to type introspection optimizations, wherein some resolution would be avoid for |

Hmmh. Odd. 2.10 fails, 2.11 does not. And |

Fixed for 2.10. Problem was not quite what I thought, but was able to pinpoint it to specific change in detecting Enum types ( Thank you again for reporting this; fix will be in 2.10.2 which should be released quite soon. |
This problem of failing to serialize an Enum instance which includes a method override only occurs in 2.10.1, not 2.10.0.
Here is a simple test:
public class EnumSerializationTestU { @Test public void testSerializationOfEnumInstanceWithOverrideMethod() { ObjectMapper om = new ObjectMapper(); om.enable(DeserializationFeature.USE_BIG_DECIMAL_FOR_FLOATS); try { String stringResult = om.writeValueAsString(EnumWithOverrideMethod.ATTRIBUITES); Map result = (Map) om.readValue(stringResult, Map.class); assertEquals("attributes", result.get("key")); } catch (JsonProcessingException e) { System.err.println("Serialization Of EnumInstanceWithOverrideMethod fails: "); e.printStackTrace(); } } @JsonFormat(shape = JsonFormat.Shape.OBJECT) public enum EnumWithOverrideMethod { DEFAULT("default"), ATTRIBUITES("attributes") { public Class sectionInfoClass () { return AttributesSectionInfo.class; } }, DOC_LAYOUT("doclayout") { public Class sectionInfoClass () { return DocLayoutSectionInfo.class; } } ; private final String key; private EnumWithOverrideMethod(String key) { this.key = key; } public String getKey() { return this.key; } public Class sectionInfoClass() { return null; } } public interface LayoutSectionInfo { } public class AttributesSectionInfo implements LayoutSectionInfo { private LinkedHashMap attributes; public LinkedHashMap getAttributes() { return attributes; } } public class DocLayoutSectionInfo implements LayoutSectionInfo { private String relatedDocField; public String getRelatedDocField() { return relatedDocField; } public void setRelatedDocField(String relatedDocField) { this.relatedDocField = relatedDocField; } } }The text was updated successfully, but these errors were encountered:
