java接收ret的文本文件输入

Question

@GetMapping(value = "/test")
@ResponseBody
public String getText(@RequestParam String text) {
    return modified(text);
}

我如何调整此代码以使其在.txt文件中接收相同的文本？

@GetMapping(value = "/try")
@ResponseBody
public String getText(@RequestParam("filePath") String filePath) throws 
IOException {
File file = new File(filePath);
BufferedReader reader = new BufferedReader(new FileReader(file));
String line = reader.readLine();
StringBuilder builder = new StringBuilder();
while (line != null) {
    builder.append(line);
    line = reader.readLine();
}
reader.close();
return modified(builder.toString());
