通过Jackson注解将具有大量属性的json反序列化为java类。

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

public class MyClass {
    @JsonProperty("property1")
    private String property1;

    @JsonProperty("property2")
    private int property2;

    // Getters and setters

    public static void main(String[] args) {
        String json = "{\"property1\":\"value1\",\"property2\":123}";

        try {
            ObjectMapper objectMapper = new ObjectMapper();
            MyClass myObject = objectMapper.readValue(json, MyClass.class);

            System.out.println(myObject.getProperty1());
            System.out.println(myObject.getProperty2());
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
