直接贴代码
@GetMapping("/writeDataToFile")
public void writeDataToFile(String jsonStr) throws IOException {
//文件目录
Path rootLocation = Paths.get("folder")
if(Files.notExists(rootLocation)){
Files.createDirectories(rootLocation);
}
//data.js是文件
Path path = rootLocation.resolve("data.js");
byte[] strToBytes = jsonStr.getBytes();
Files.write(path, strToBytes);
}
