使用Jackson解析Json并将其分配给DTO

import com.fasterxml.jackson.databind.ObjectMapper;

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

        try {
            // 创建ObjectMapper对象
            ObjectMapper objectMapper = new ObjectMapper();

            // 解析JSON并将其分配给DTO
            PersonDTO personDTO = objectMapper.readValue(json, PersonDTO.class);

            // 打印DTO对象的属性
            System.out.println("Name: " + personDTO.getName());
            System.out.println("Age: " + personDTO.getAge());
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

class PersonDTO {
    private String name;
    private int age;

    // 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;
    }
}
