java实体类转成map的方式

1.第一种

 <!-- 配置gson -->
        <dependency>
            <groupId></groupId>
            <artifactId>gson</artifactId>
            <version>2.8.6</version>
        </dependency>

       Map<String, Object> map = null;
  String jsonString = (uploadBaseEntity);
       Gson gson = new Gson();
        map = new HashMap<>();
        map = (jsonString, ());

2.第二种

/**
     * 对象转化为Map
     *
     * @param obj
     * @return
     * @throws Exception
     */
    public static Map<String, String> objectToMap01(Object obj) throws Exception {
        if (obj == null) {
            return null;
        }
        Map<String, String> map = new HashMap<String, String>();

        Field[] declaredFields = ().getDeclaredFields();
        for (Field field : declaredFields) {
            (true);
            ((), (String) (obj));
        }

        return map;
    }
