我有以下代码, 它所做的是,它从http连接获取响应并将其写入logs.txt。 当我执行程序时,响应将写入txt文件,但是当我再次运行同一程序时,它不会将响应写入txt文件。
BufferedReader in = new BufferedReader(new InputStreamReader(con.getInputStream()));
String inputLine;
StringBuffer response = new StringBuffer();
while ((inputLine = in.readLine()) != null) {
response.append(inputLine);
}
in.close();
BufferedWriter out = new BufferedWriter(new FileWriter("C:/Users/mkumaru/Desktop/Elastic/elasticsearch/server/logs/logs.txt"));
try {
out.write(response.toString());
}
catch (IOException e)
{
System.out.println("Exception ");
}
finally
{
out.close();
}
所以我期望的是, 在第一次执行时,logs.txt应该是 response1
在同一程序的第二次执行中, 回应1 response2
我该怎么做。
答案 0 :(得分:0)
BufferedWriter writer = new BufferedWriter(
new FileWriter("C:/Users/mkumaru/Desktop/Elastic/elasticsearch/server/logs/logs.txt", true) //Set true for append mode
);
writer.newLine(); //Add new line
writer.write(textToAppend);
