How Deserialization Yaml Array to List<ParserRule> type

[Zixuan Liu]

JavaBean

@Data
public class ParserRule {
    private String bankName;
    private String bankCode;
}

Yaml

- bankName: Test1
  bankCode: CMB
- bankName: Test2
   bankCode: BOC

main.java

Yaml yaml = new Yaml();
List<ParserRule> lists = (List<ParserRule>)yaml.load(body);
System.out.println(lists);    // this is ok
for(ParserRule list : lists){
    System.out.println(list.getBankcode());   // this is error
}

Exception in thread "main" java.lang.ClassCastException: java.util.LinkedHashMap cannot be cast to com.nodece.ParserRule

i need your help， thanks

Duplicate of #387.

ATM, I don't see how you can do it without explicit tags for ParseRule.

Or if you put that list as property of some JavaBean it may work.

@Data
public class RulesContainer {
     private List<ParseRule> rules;
}

BTW, this is wrong place to ask question. Especially starting "How ...."
