然后,我们可以使用以下代码来读取JSON文件并将其转换为Person对象: publicclassMain{publicstaticvoidmain(String[]args){try{StringjsonString=JsonFileReader.readFile("person.json");Personperson=JsonToObjectConverter.convertToObject(jsonString,Person.class);System.out.println(person.getName());System.out.print...
现在,我们可以将上述两个步骤整合到一个示例程序中,以展示如何从文件中读取JSON内容并转换为JSONObject。 publicclassMain{publicstaticvoidmain(String[]args){try{StringfilePath="path/to/your/jsonfile.json";StringjsonContent=JsonReader.readFileContent(filePath);JSONObjectjsonObject=JsonParser.parseJson(jsonCon...
4、读取JSON文件获取字符串,并转为对象 publicstaticJSONObjectreadTxtToJson(String txt){File file=newFile(txt);String json="";FileInputStream fis=null;InputStreamReader isr=null;BufferedReader br=null;try{fis=newFileInputStream(file);// 文件输入流isr=newInputStreamReader(fis,"utf-8");// 转为...
public static <T> T jsonFile2Object(String finalPath, Class<T> targetClass) { String jsonString; File file = new File(finalPath); try { FileInputStream inputStream = new FileInputStream(file); int size = inputStream.available(); byte[] buffer = new byte[size]; inputStream.read(buffer...
path=path.replace("file:/",""); }*/ClassPathResource resource=newClassPathResource("menu.json"); File filePath=resource.getFile(); JSONArray btnArray=null;//读取文件String input=FileUtils.readFileToString(filePath,"UTF-8");//将读取的数据转换为JSONObjectJSONObject jsonObject=JSONObject.fromOb...
打开资源管理器,在工程TestReadJSON 文件夹下,创建一个 文件夹:lib,在其中放入:gson-2.8.0.jar 工程结构目录如下: 选择gson-2.8.0.jar,右键->Build Path->Add to Build Path 此时,工程结构目录一览: 代码: packagecom.siwuxie095.json; importjava.io.FileNotFoundException; ...
You can refer to an existing thread [1] to understand how to read a JSON file from the resource folder. importcom.fasterxml.jackson.databind.ObjectMapper;importcom.fasterxml.jackson.databind.type.CollectionType;importcom.fasterxml.jackson.databind.type.TypeFactory;importcom....
