1、继续将这个LinkedHashMap进行序列化程JSON,然后再反序列化,但是这样效率就低了。 2、直接使用自带的convertValue方法将这个LinkedHashMap以Object类型转成想要的实体。 样例: POJO pojo = mapper.convertValue(singleObject, POJO.class);//or:List<POJO> pojos = mapper.convertValue(listOfObjects,newTypeReference<...

failed; nested exception is java.lang.ClassCastException: java.util.LinkedHashMap cannot be cast to 使用Map<String,Object> map = data，然后使用map.get()来获取里面的值。注意：如果有多个字段的话，不建议使用这样来做，太傻了。使用阿里的fastJson来将这个linkedHashMap转换成对象。
