Jackson JSON:仅使用流中的单个对象

import com.fasterxml.jackson.databind.ObjectMapper;

public class Main {
    public static void main(String[] args) throws Exception {
        // 创建ObjectMapper对象
        ObjectMapper objectMapper = new ObjectMapper();

        // 将对象序列化为JSON字符串
        MyObject myObject = new MyObject();
        String json = objectMapper.writeValueAsString(myObject);
        System.out.println(json);

        // 将JSON字符串反序列化为对象
        MyObject deserializedObject = objectMapper.readValue(json, MyObject.class);
        System.out.println(deserializedObject);
    }
}

class MyObject {
    private String name;
    private int age;

    // 省略getter和setter方法

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