尝试将我自己的包导入 servlet 时出现包不存在错误

Question

我正在尝试使用 tomcat 将我自己的包导入到我正在制作的 servlet 中。

我使用的两个 java 文件是 servlet (movieServlet.java)，另一个我试图从包中导入的类 (Movie.java)

文件夹的层次结构是：

classes
|
+--movieServlet.java
|
+--movie
   |
   +--Movie.java

movieServlet.java

import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
import javax.servlet.annotation.WebServlet;
import movie.Movie;

@WebServlet(urlPatterns = {"/movieServlet"})
public class movieServlet extends HttpServlet {

public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
    PrintWriter out = response.getWriter();

    Movie Movie = new Movie();
    request.setAttribute("movies", Movie.getAllMovies());

    RequestDispatcher dispatcher = getServletContext().getRequestDispatcher("/WEB-INF/jsps/movies.jsp");
    dispatcher.forward(request,response);
} 


public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
    PrintWriter out = response.getWriter();


    RequestDispatcher dispatcher = getServletContext().getRequestDispatcher("/WEB-INF/jsps/movieDetails.jsp");
    dispatcher.forward(request,response);
} 

}

这是 Movie.java 的顶部（它是一个长文件）

package movie;
import java.util.*;
import java.util.List;
import javax.sql.*;
import java.sql.*;
import javax.naming.InitialContext;

public class Movie implements java.io.Serializable
{
private static DataSource dataSource = null;
private static Connection c = null;

private int id;
private String title;
private String url;
private int year;

public Movie(){}

如果需要更多信息，请询问:)，这一直困扰着我。

我是新来的，如果我的回答不完美，请见谅。正如您所提到的，您想导入自己的包含 Movie 类的包。我尝试实现你所有的主要方法，它运行完美，我从 Movie.java 中获得了我的价值。

movieServlet.java

import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import movie.Movie;

public class movieServlet extends HttpServlet {

    protected void doGet(HttpServletRequest request, HttpServletResponse response)
           throws ServletException, IOException {
              PrintWriter out = response.getWriter();
               Movie Movie = new Movie();
               request.setAttribute("movies", Movie.getAllMovies());
               out.println(request.getAttribute("movies"));
   }


 }

Movie.java

package movie;
public class Movie {
String s;
   public Movie(){
      s="hello zDoctor";   
   }
   public String getAllMovies(){
       return s;
   }
}

servlet output
