将json字符串反序列化为具有属性的对象，这些属性是jackson中的字符串

import com.fasterxml.jackson.databind.ObjectMapper;

public class JsonDeserializationExample {
    public static void main(String[] args) {
        String jsonString = "{\"name\":\"John\", \"age\":30}";

        try {
            ObjectMapper objectMapper = new ObjectMapper();
            Person person = objectMapper.readValue(jsonString, Person.class);

            System.out.println("Name: " + person.getName());
            System.out.println("Age: " + person.getAge());
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

class Person {
    private String name;
    private int age;

    // Getters and setters

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }
}
