代码如下

复制代码

public void writeData2Txt(String content) {
　　 //存放文件的目录
String fileDir = ServletActionContext.getServletContext().getRealPath("D:/file/");
　　 //简单的生成文件名
String fileName =new SimpleDateFormat("yyyyMMddHHmmsszzz").format(new Date())+".txt";
File txtFile= new File(fileDir,fileName);
BufferedReader bufferedReader = null;
BufferedWriter bufferedWriter = null;
try {
bufferedReader = new BufferedReader(new StringReader(content));
bufferedWriter = new BufferedWriter(new FileWriter(txtFile));
char buf[] = new char[1024]; //字符缓冲区
　 int len;
while ((len = bufferedReader.read(buf)) != -1) {
bufferedWriter.write(buf, 0, len);
}

} catch (IOException e) {
e.printStackTrace();
} finally {
try {
bufferedWriter.flush();
bufferedWriter.close();
bufferedReader.close();

} catch (IOException e) {
e.printStackTrace();
}
}

}
