将JSON类反序列化为不同名称的Java类

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

class MyJsonClass {
    @JsonProperty("json_property_name")
    private String javaPropertyName;

    // getter and setter methods
    // ...

    public static void main(String[] args) throws Exception {
        String json = "{\"json_property_name\":\"value\"}";

        ObjectMapper objectMapper = new ObjectMapper();
        MyJsonClass myJsonClass = objectMapper.readValue(json, MyJsonClass.class);

        System.out.println(myJsonClass.getJavaPropertyName()); // 输出：value
    }
}
