Servlet 非常漂亮，可以读取具有英文名称(如 hello.txt)的文件。它不想读取具有俄语名称的文件，例如pushkin.txt。有谁能帮忙解决这个问题吗？
这是代码:
import java.io.File;
import java.io.FileReader;
import java.io.IOException;
import java.io.PrintWriter;
import java.util.ArrayList;
import java.util.List;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
public class servlet extends HttpServlet {
/**
*
*/
private static final long serialVersionUID = 1L;
public static List<String> getFileNames(File directory, String extension) {
List<String> list = new ArrayList<String>();
File[] total = directory.listFiles();
for (File file : total) {
if (file.getName().endsWith(extension)) {
list.add(file.getName());
}
if (file.isDirectory()) {
List<String> tempList = getFileNames(file, extension);
list.addAll(tempList);
}
}
return list;
}
@SuppressWarnings("resource")
protected void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException{
response.setContentType("text/html; charset=UTF-8");
String myName = request.getParameter("text");
List<String> files = getFileNames(new File("C:\\Users\\vany\\Desktop\\test"), "txt");
for (String string : files) {
if (myName.equals(string)) {
try {
File file = new File("C:\\Users\\vany\\Desktop\\test\\" + string);
FileReader reader = new FileReader(file);
int b;
PrintWriter writer = response.getWriter();
writer.print("<html>");
writer.print("<head>");
writer.print("<title>HelloWorld</title>");
writer.print("<body>");
writer.write("<div>");
while((b = reader.read()) != -1) {
writer.write((char) b);
}
writer.write("</div>");
writer.print("</body>");
writer.print("</html>");
}
finally {
if(reader != null) {
try{
reader.close();
} catch (Exception e) {
e.printStackTrace();
}
}
}
}
}
}
}

最佳答案
我认为您对这些陈述有疑问
for (String string : files) {
if (myName.equals(string)) {
我会这样比较
for (File file: files) {
if (myName.equals(file.getName())) {
希望对你有帮助。 注:感谢您的评论，您可以尝试一下。
