//方法2 先将json字符串转换成JSONObject对象JSONObjectjsonObject1=newJSONObject(JSON.parseObject(jsonStr));//将转换后的JSONObject对象转换成Student对象Studentstudent1=(Student) JSONObject.toJavaObject(jsonObject1,Student.class); 1 2 3 4 示例:解析如下json字符串 { “name”: “Tom”, “Grade”: ...
步骤二:使用Jackson库转换json字符串 我们可以使用下面的代码将json字符串转为List对象: importcom.fasterxml.jackson.core.type.TypeReference;importcom.fasterxml.jackson.databind.ObjectMapper;publicclassJsonUtils{publicstaticList<Person>jsonToList(StringjsonStr){ObjectMappermapper=newObjectMapper();try{returnmapper.r...
Type listType = new TypeToken<List<Person>>() {}.getType(); List<Person> personList = gson.fromJson(jsonArray, listType); return personList; } 4.使用Org.json Org.json或JSON-Java是一个简单轻量的基于Java的库,我们可以使用它来进行JSON和XML、HTTP头、Cookies和CDL之间的编码和解码。它完全符合...
JSONObject jsonObject =newJSONObject(result);//result 是json对象,如果不是直接报错 JSONArray jsonArray = jsonObject.getJSONArray("list");//这儿list是json 本身的名字叫list for(inti = 0; i < jsonArray.length(); i++) { JSONObjectobject= jsonArray.getJSONObject(i);// JSON 是java 原生方...

转换为List<T>对象:根据需要,将解析后的Java对象转换为List<T>对象。 下面是一个使用Jackson库进行JSON解析的示例代码: 代码语言:txt 复制 // 导入Jackson库的相关依赖 import com.fasterxml.jackson.databind.ObjectMapper; import com.fasterxml.jackson.core.type.TypeReference; // 假设收到的JSON响应为respons...
