LinkedHashMap转ArrayList

第一种、LinkedHashMap转数组，数组再转成ArrayList

ObjectMapper objectMapper=new ObjectMapper();
ResultPortalBean rpb=(ResultPortalBean)objectMapper.readValue(data,ResultPortalBean.class);
UserInfoBO[] userArr=(UserInfoBO[])objectMapper.readValue(objectMapper.writeValueAsString(rpb.getData),UserInfoBO[].class);
List<UserInfoBO> userList=Arrays.asList(userArr);

第二种、jackson自带convertValue方法转换

ObjectMapper objectMapper=new ObjectMapper();
ResultPortalBean rpb=(ResultPortalBean)objectMapper.readValue(data,ResultPortalBean.class);
List<UserInfoBO> userList=( List<UserInfoBO>)objectMapper.convertValue(objectMapper.writeValueAsString(rpb.getData),new TypeReference<List<UserInfoBO>>(){});
