如何使用Jackson序列化到java.util.List和java.util.Map

implementation 'com.fasterxml.jackson.core:jackson-databind:2.12.4'

public class Student {
    private String name;
    private int age;
    private List<String> subjects;
    private Map<String, Integer> scores;

    // 添加构造函数、getter和setter方法
}

import com.fasterxml.jackson.databind.ObjectMapper;

public class SerializationExample {
    public static void main(String[] args) {
        ObjectMapper mapper = new ObjectMapper();

        // 创建一个Student对象
        Student student = new Student();
        student.setName("John");
        student.setAge(20);
        student.setSubjects(List.of("Math", "Science"));
        student.setScores(Map.of("Math", 90, "Science", 85));

        try {
            // 序列化为List
            String listJson = mapper.writeValueAsString(List.of(student));
            System.out.println("Serialized List: " + listJson);

            // 序列化为Map
            String mapJson = mapper.writeValueAsString(Map.of("student", student));
            System.out.println("Serialized Map: " + mapJson);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

Serialized List: [{"name":"John","age":20,"subjects":["Math","Science"],"scores":{"Science":85,"Math":90}}]
Serialized Map: {"student":{"name":"John","age":20,"subjects":["Math","Science"],"scores":{"Science":85,"Math":90}}}
