读取文本文件中所有内容，java

1、使用Files.lines() 方法，逐行读取，然后拼接

        //        读取 
        String interfaceTxtPath="D:\\基础.postman_collection.json";
        
        List<String> lines = Files.readAllLines(Paths.get(interfaceTxtPath), StandardCharsets.UTF_8);
        String content= String.join(System.lineSeparator(),lines);

2、使用BufferedReader 逐行读取，然后以字符串存储

    public static void main(String[] args) throws IOException {
        String path = "D:\\基础.postman_collection.json"; 
        StringBuilder contentBuilder = new StringBuilder();
        try (BufferedReader br = new BufferedReader(new FileReader(path))) {
            String line;
            while ((line = br.readLine()) != null) {
                contentBuilder.append(line).append(System.lineSeparator());
            }
        } catch (IOException e) {
            e.printStackTrace();
        }

        String fileContent = contentBuilder.toString();
        System.out.println(fileContent);

    }

3、使用Files.readString()
