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=...
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...
Student o = JSONObject.parseObject(jsonString, Student.class); 2.json转List json: 花括号{} String jsonString = “[{"id":1, "name": "zhangsan", "sex": "male", "age": 18, :city": "Beijing"},{"id": 2, "name": "lisi", "sex": "female", "age": 18, "city": "Shanghai"...
package com.zkn.newlearn.json; import com.alibaba.fastjson.JSON; import com.alibaba.fastjson.JSONArray; import com.alibaba.fastjson.JSONObject; import java.util.List; import java.util.Map; public class JsonToMapTest02 { public static void main(String[] args){ String strArr = "[{\"0\":\...
JSON与List之间的转换 jsonString转换为list: JSONArray jsonArray=JSONArray.fromObject(result); List<RentCar> books=(List)JSONArray.toList(jsonArray, Class); list转换为jsonString Gson gson=new Gson(); bookString = gson.toJson(list);
2.2json字符串转成JsonArrayToList[],代码实现比较简单 packagecom.cppba.jackson;importcom.fasterxml.jackson.annotation.JsonProperty;importcom.fasterxml.jackson.databind.ObjectMapper;importjava.io.IOException;importjava.util.List;publicclassStringToObject{publicstaticObjectMapperobjectMapper=newObjectMapper();publicst...
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; ...
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>...
