YangFei updated FLINK-12412: ---------------------------- Description: public static class UserBehavior { public long userId; public long itemId; public int categoryId; public long timestamp; public List<String> comments; } public static void main(String[] args) throws Exception { PojoTypeInfo<UserBehavior> pojoType = (PojoTypeInfo<UserBehavior>) TypeExtractor.createTypeInfo(UserBehavior.class); } ); } The filed `comments` in `UserBehavior` will be extracted by TypeExtractor to `GenericType` . I think it can be extracted to ListTypeInfo . This would be a big improvement as in many cases classes including List or Map was: public static class UserBehavior { public long userId; public long itemId; public int categoryId; public long timestamp; public List<String> comments; } public static void main(String[] args) throws Exception { PojoTypeInfo<UserBehavior> pojoType = (PojoTypeInfo<UserBehavior>) TypeExtractor.createTypeInfo(UserBehavior.class); }); } The filed `comments` in `UserBehavior` will be extracted by TypeExtractor to `GenericType` . I think it can be extracted to ListTypeInfo .
