SpringBoot+Mybatis使用Enum枚举类型总是报错No enum constant XX问题

public class Question {
	private String id;
	// 类型
	private QuType quType;
    。。get set
}

public enum QuType {
 
	YESNO("是否","yesno", 0);
	
	private String quName;
	private String quEnName;
	private int index;
	
	QuType(String quName,String quEnName,int index){
		this.cnName=quName;
		this.quEnName=quEnName;
		this.index=index;
	}
 
	..get set
}
