首先Maven引入Hutool依赖：

        <dependency>
            <groupId>cn.hutool</groupId>
            <artifactId>hutool-all</artifactId>
            <version>5.8.21</version> <!-- 请根据实际最新版本调整 -->
        </dependency>

测试：

1、创建一个User实体类 

@Data
@RequiredArgsConstructor
@AllArgsConstructor
public class User {
    private Long id;
    private String name;
    private String sex;
    private String address;

}

2、代码测试：

    public void auditChanges() {


        User oldEntity = new User(1L,"小明", "男", "广州");
        User newEntity = new User(1L,"小明", "女", "深圳");

        // 获取对象的属性
        Map<String, Object> oldMap = BeanUtil.beanToMap(oldEntity);
        Map<String, Object> newMap = BeanUtil.beanToMap(newEntity);
        System.out.println("-----对象User字段的变化记录------");
        oldMap.forEach((key, oldValue) -> {
            Object newValue = newMap.get(key);
            if (newValue != null && !oldValue.equals(newValue)) {
                System.out.println("字段名称: " + key + ", 旧值: " + oldValue + ", 新值: " + newValue);
            }
        });

    }

3、运行结果：
