枚举类示例

     * UserTypeEnum  ROOT_ADMIN => ROOT_ADMIN.getName()...
     * UserTypeEnum  ADMIN => ADMIN.getName()...
     * UserTypeEnum  USER => USER.getName()...
     * UserTypeEnum valueOf(String enum) // 字符串转枚举
     * UserTypeEnum[] values()
     */

    ADMIN("2", "管理员", "相关权限"),
    USER("3", "普通用户", "普通权限");
    private String name;
    private String code;
    private String desc;

    }
    public String getName() {
