出错的原因是Person类中缺少无参构造函数

public class Person {
    private String lastName;

    private String firstName;

    public String getLastName() {
        return lastName;
    }

    public void setLastName(String lastName) {
        this.lastName = lastName;
    }

    public String getFirstName() {
        return firstName;
    }

    public void setFirstName(String firstName) {
        this.firstName = firstName;
    }

    public Person(String lastName, String firstName) {
        this.lastName = lastName;
        this.firstName = firstName;
    }

    public Person() {
        super();
    }

    @Override
    public String toString() {
        return "Person{" +
                "lastName='" + lastName + '\'' +
                ", firstName='" + firstName + '\'' +
                '}';
    }
}
补上红色部分就好了
