一、在JSP页面中读取本地文件内容：
<%
try {
BufferedReader in = new BufferedReader(new FileReader("D:/test.txt"));
String file = "";
String temp = "";
while((temp=in.readLine())!=null) {
file += temp + "<br>";
}
out.println(file);
in.close();
out.flush();
} catch(Exception e) {
e.printStackTrace();
}
%>
二、在JSP页面中写入文件内容：
<%
try {
PrintWriter writer = new PrintWriter(new BufferedWriter(new FileWriter("D:/test.txt", true)));
writer.write(content);
writer.close();
out.println("已经写入到文件中");
} catch(Exception e) {
e.printStackTrace();
}
%>
