有没有真正的轻量级4j示例将json请求映射到Java POJO对象？

import com.fasterxml.jackson.annotation.JsonProperty;

public class User {
    @JsonProperty("name")
    private String name;
    
    @JsonProperty("age")
    private int age;
    
    // 省略getter和setter方法
}

import com.fasterxml.jackson.databind.ObjectMapper;

public class Main {
    public static void main(String[] args) throws Exception {
        String json = "{\"name\":\"John\",\"age\":30}";
        
        ObjectMapper objectMapper = new ObjectMapper();
        User user = objectMapper.readValue(json, User.class);
        
        System.out.println(user.getName()); // 输出：John
        System.out.println(user.getAge()); // 输出：30
    }
}
