我们可以使用ObjectMapper类的readValue方法将JSON字符串转换为一个List<Student>对象数组。下面是完整的代码示例: importcom.fasterxml.jackson.core.type.TypeReference;importcom.fasterxml.jackson.databind.ObjectMapper;importjava.util.List;publicclassJsonToListExample{publicstaticvoidmain(String[]args){StringjsonString=...
public class HwInstance {private String fault;private String id;@JsonProperty("OS-EXT-STS:task_state")private String state;@JsonProperty("cpu_options")private Object options;} 转List 方法一：@Autowiredprivate ObjectMapper objectMapper;String json = "";JSONObject jsonObject = JSON.parseObject(json)...
1.把String转换为List(str转换为list) List<T> list = new ArrayList<T>(); JSONArray jsonArray = JSONArray.fromObject(str);//把String转换为json list = JSONArray.toList(jsonArray,t);//这里的t是Class<T> 在这里,因为得到json字符串的时候用的是 JSONArray.fromObject(collenction),所有,在讲json...
//DEMO2 转换列表List<Item> configList =newArrayList<>(); configList.add(newItem("1","100")); configList.add(newItem("2","100")); configList.add(newItem("3","100")); configList.add(newItem("4","100")); String json=JSON.toJSONString(configList); System.out.println(json); L...
jsonString转List (Fastjson) <?>Domain
2、下面来转一下,这里的PsOrg是一个POJO String returnObj = jso.get("returnObj").toString(); JavaType javaType = getCollectionType(ArrayList.class, PsOrg.class); List<PsOrg> psOrgList = (List<PsOrg>) objectMapper.readValue(returnObj, javaType); ...
//第一种方式List<Map<String,String>> listObjectFir=(List<Map<String,String>>)JSONArray.parse(strArr);System.out.println("利用JSONArray中的parse方法来解析json数组字符串");for(Map<String,String> mapList : listObjectFir){for(Map.Entryentry : mapList.entrySet()){System.out.println( entry....
1.后台接收json数组转成封装实体类的List package no.integrasco.ingentia.news.qaedition; public class Person { private String name; private int age; public String getName() { return name; } public void setName(String name) { this.name = name; ...
//第一种方式 List<Map<String,String>> listObjectFir = (List<Map<String,String>>) JSONArray.parse(strArr); System.out.println("利用JSONArray中的parse方法来解析json数组字符串"); for(Map<String,String> mapList : listObjectFir){ for (Map.Entry entry : mapList.entrySet()){ System.out.pr...
JSON类型的String转成ListString //后端调⽤接⼝ List<String> directives = new ArrayList<>();while (matcher.find()) { directives.add(matcher.group(1));LOGGER.info("处理标签：{}", matcher.group(1));} JSONObject jsonObject = new JSONObject();Map map2=new HashMap();//将List<String>...
