Jackson不能用空格解析json

import com.fasterxml.jackson.databind.ObjectMapper;

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

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

        try {
            // 解析JSON数据
            Person person = objectMapper.readValue(jsonData, Person.class);

            // 输出解析结果
            System.out.println("Name: " + person.getName());
            System.out.println("Age: " + person.getAge());
            System.out.println("City: " + person.getCity());
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

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

    // 省略getter和setter方法
}
