使用jackson反序列化改造后的json，其中相同的变量名可以表示两个不同的对象

import com.fasterxml.jackson.annotation.JsonProperty;
import com.fasterxml.jackson.databind.ObjectMapper;

class Person {
    @JsonProperty("name")
    private String personName;

    @JsonProperty("age")
    private int personAge;

    public String getPersonName() {
        return personName;
    }

    public void setPersonName(String personName) {
        this.personName = personName;
    }

    public int getPersonAge() {
        return personAge;
    }

    public void setPersonAge(int personAge) {
        this.personAge = personAge;
    }
}

public class JsonDeserializationExample {
    public static void main(String[] args) throws Exception {
        String json = "{\"name\":\"John\",\"age\":30}";
        ObjectMapper objectMapper = new ObjectMapper();
        Person person = objectMapper.readValue(json, Person.class);

        System.out.println("Name: " + person.getPersonName());
        System.out.println("Age: " + person.getPersonAge());
    }
}
