循环读取文件：
File[] dbfiles=new File("E:\pengyw\workspace1\bbsics_dk_2.0\log").listFiles();
for(File file:dbfiles){
String Str = JavaUtil.readUTF8File(file);
if(Str.indexOf("ception")!=-1){
System.out.println(file.getName());
}else
System.out.println(0);
}
读取文件方法
public static String readUTF8File(File file) {

else
content = content + new String(data, 0, len, "GBK");
len = fs.read(data);
i++;
}
fs.close();
