我想以追加模式写入临时文件.我看到文件已创建,但Stringbuffer中的数据未写入.有人可以告诉我为什么吗？请在下面找到我写的代码,
public static void writeToFile(String pFilename,StringBuffer sb)
throws IOException {
String property = "java.io.tmpdir";
String tempDir = System.getProperty(property);
File dir = new File(tempDir);
File filename = File.createTempFile(pFilename,".tmp",dir);
FileWriter fileWriter = new FileWriter(filename.getName(),true);
System.out.println(filename.getName());
BufferedWriter bw = new BufferedWriter(fileWriter);
bw.write(sb.toString());
bw.close();
}
解决方法
FileWriter fileWriter = new FileWriter(filename.getName(),true);
应该
FileWriter fileWriter = new FileWriter(filename,true);
