如何将Groovy中的文件读入字符串？

File file = new File("path/to/your/file.txt")
String content = file.getText()

File file = new File("path/to/your/file.txt")
InputStream inputStream = new FileInputStream(file)
BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream))
StringBuilder content = new StringBuilder()
String line
while ((line = reader.readLine()) != null) {
    content.append(line).append("\n")
}
reader.close()
inputStream.close()

File file = new File("path/to/your/file.txt")
StringBuilder content = new StringBuilder()
file.withReader { reader ->
    String line
    while ((line = reader.readLine()) != null) {
        content.append(line).append("\n")
    }
}
