如何使用Java stream collect创建一个以字符串作为关键字而不是对象的映射？

import java.util.List;
import java.util.Map;
import java.util.stream.Collectors;

public class Main {
    public static void main(String[] args) {
        List<Person> persons = List.of(
                new Person("John", 25),
                new Person("Jane", 30),
                new Person("Bob", 35)
        );

        Map<String, Person> personMap = persons.stream()
                .collect(Collectors.toMap(Person::getName, person -> person));

        System.out.println(personMap);
    }
}

class Person {
    private String name;
    private int age;

    public Person(String name, int age) {
        this.name = name;
        this.age = age;
    }

    public String getName() {
        return name;
    }

    public int getAge() {
        return age;
    }

    @Override
    public String toString() {
        return "Person{" +
                "name='" + name + '\'' +
                ", age=" + age +
                '}';
    }
}

{Bob=Person{name='Bob', age=35}, Jane=Person{name='Jane', age=30}, John=Person{name='John', age=25}}
