Expected BEGIN_OBJECT but was BEGIN_ARRAY

json解析时发生错误：

json数据格式：

 "directors":[        {            "alt":"https://movie.douban.com/celebrity/1027853/",            "avatars":{                "small":"https://img3.doubanio.com/view/celebrity/s_ratio_celebrity/public/p324.webp",                "large":"https://img3.doubanio.com/view/celebrity/s_ratio_celebrity/public/p324.webp",                "medium":"https://img3.doubanio.com/view/celebrity/s_ratio_celebrity/public/p324.webp"            },            "name":"吴宇森",            "id":"1027853"        }    ],

PersonBean：

public class PersonBean implements Serializable {    private  String alt;    private ImagesBean avatars;    private String  name;    private  String  id;    public String getAlt() {        return alt;    }    public void setAlt(String alt) {        this.alt = alt;    }    public ImagesBean getAvatars() {        return avatars;    }    public void setAvatars(ImagesBean avatars) {        this.avatars = avatars;    }    public String getName() {        return name;    }    public void setName(String name) {        this.name = name;    }    public String getId() {        return id;    }    public void setId(String id) {        this.id = id;    }    @Override    public String toString() {        return "PersonBean{" +                "alt='" + alt + '\'' +                ", avatars=" + avatars +                ", name='" + name + '\'' +                ", id='" + id + '\'' +                '}';    }}

修改前：

public class MovieDetailBean implements Serializable {private PersonBean directors;public PersonBean getDirectors() {        return directors;    }public void setDirectors(PersonBean directors) {        this.directors = directors;   }   }

修改后：

public class MovieDetailBean implements Serializable {private List<PersonBean> directors;public List<PersonBean> getDirectors() {        return directors;    }public void setDirectors(List<PersonBean> directors) {        this.directors = directors;   }   }
