里面有三个方法 open(String filename)
打开文件操作
String readLine() 和BufferedReader差不多，执行一次读取一行，直到返回Null
close()关闭文件
怎么写啊，简单点就可以了
刚刚给人写的，工你参考
import java.io.BufferedReader;
import java.io.File;
import java.io.FileReader;
import java.io.IOException;
public class ReadFile {
public static void main(String[] args) throws IOException {
String fileContent = readFileContent("睁枣");
System.out.println(fileContent);
}
//参数string为你的文件名
private static String readFileContent(String fileName) throws IOException {
File file = new File(fileName);//读文件
BufferedReader bf = new BufferedReader(new FileReader(file));
String content = "";
StringBuilder sb = new StringBuilder();
while(content != null){
content = bf.readLine();//悉斗拆读每一行
if(content == null){//读销雹到null,返回
break;
}
sb.append(content.trim());
}
bf.close();//关闭文件
return sb.toString();
}
}
Reader reader = null;
BufferedReader br = null;
try {
// 读取复制过的日志文件
reader = new FileReader("要读取的橘世销文返基件");
br = new BufferedReader(reader);
ServletActionContext.getResponse().setContentType("圆游text/html;charset=UTF-8");
PrintWriter out =ServletActionContext.getResponse().getWriter();
String data = null;
while ((data = br.readLine()) != null) {
out.print(data);
}
} catch (IOException e) {
e.printStackTrace();
} finally {
try {
reader.close();
br.close();
} catch (Exception e) {
e.printStackTrace();
}
}
读取到response对象中
