方法1：
List returnBookResults = mapper.readValue(JSON.toJSONString(response.getData()),new TypeReference(){});
方法2：
JavaType javaType = mapper.getTypeFactory().constructParametricType(ArrayList.class, ReturnBookResult.class);
List returnBookResults = (List)mapper.readValue(JSON.toJSONString(response.getData()), javaType);

json转复杂类型：

private <T> BaseResponse parseResponse(String response, Class<T> clz,Class<?> ...listClz) throws IOException {
        ObjectMapper objectMapper = new ObjectMapper();
        objectMapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);
        if(clz==List.class){
            BaseResponse baseResponse = new BaseResponse();
            JavaType javaType = objectMapper.getTypeFactory().constructParametricType(BaseResponseList.class, listClz);
            BaseResponseList baseResponseList = objectMapper.readValue(response,javaType);
            baseResponse.setData(baseResponseList.getData());
            baseResponse.setStatus(baseResponseList.getStatus());
            return baseResponse;
        } else {
            JavaType javaType = objectMapper.getTypeFactory().constructParametricType(BaseResponse.class, clz);
            BaseResponse baseResponse = objectMapper.readValue(response,javaType);
            return baseResponse;
        }
    }
