如何在JAVA中使用jackson解析字符串转换为json？

<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-databind</artifactId>
    <version>2.12.3</version>
</dependency>

public class Person {
    private String name;
    private int age;

    // 必须提供默认构造函数
    public Person() {}

    // 提供getter和setter方法
    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;
    }
}

import com.fasterxml.jackson.databind.ObjectMapper;

public class Main {
    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();
        }
    }
}
