java实体entity<----->map互转

 

一:entity转map

一句搞定，直接返回map对象：
import org.springframework.cglib.beans.BeanMap;

BeanMap.create(entityObj);

也可用jackson的ObjectMapper 转

 

二:map转实体类

        Map<String,String> map = new LinkedHashMap<>();
        ObjectMapper objectMapper = new ObjectMapper();
        User user = objectMapper.convertValue(map, User.class);
