我经历了类似的问题，但答案似乎并没有解决这个问题。我从GitHub https://github.com/PCS0725/blogprabhat下载了这个简单的项目来学习java web开发。我使用Eclipse来完成这个。我在导入java类文件时出错。在Eclipse中，它显示无法解决导入java.util。

<%@page import="main.Config"%>
<%@page import="java.util.Date"%>
<%@page import="java.util.ArrayList"%>
<%@page import="main.datalayer.Database"%>
<%@page import = "main.model.Article" %>
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>
<!DOCTYPE html>
<html lang="en">
  <head>
    <title>Welcome Page</title>
    <link rel="stylesheet" type="text/css" href="<%=Config.style %>" />
  </head>
  <body>
    <div id="container">
      <a href="."><img id="logo2" src="<%=Config.imageSrc %>" alt="My name here"></a>
       <ul id="headlines">
      <%
            ArrayList<Article> articles = Database.getList(Config.numRows); //number of articles to show on homepage
            int i = 0;
            for(i=0; i<articles.size();++i)                     //parse all articles and diplay in a format
            {
                int id = articles.get(i).getId();
                Date date = articles.get(i).getPublicationDate();
                java.text.SimpleDateFormat sdf = 
                         new java.text.SimpleDateFormat("dd MMMM ");
                String dte = sdf.format(date);
                //passing a paramter(viewArticleId) to viewArticle.jsp to specify the article
        %>
                <li>
                    <h2>
                        <span class="pubDate"><%=dte %></span><a href="viewArticle.jsp?viewArticleId=<%=id%>"><%=articles.get(i).getTitle()%></a>
                    </h2>
                    <p class="summary"><%=articles.get(i).getSummary() %></p>
            </li>
            <%
            }
            %>
         </ul>
        
        <p><a href="archive.jsp">Article Archive</a></p>
        <div id="footer" style = "text-align : center">
          <%=Config.footer %><a href="loginForm.jsp">Site Admin</a>
         </div>
    </div>
  </body>
</html>

服务器上的错误：

我也遇到了同样的问题，我从包p1导入我的类User，但我得到了这个错误：
只能导入类型。p1.用户解析为包
我所做的就是将pageEncoding="ISO-8859-1"更改为pageEncoding="UTF-8"，并且成功了！

<%@ page language="java" contentType="text/html; charset=ISO-8859-1" 
    pageEncoding="UTF-8"%>
   <%@page import="p1.User" %>

字符串
将页面编码更改为UTF-8可能已通过确保更好地处理字符和字节序列来修复此问题。有时，字符编码问题可能会导致代码解释中出现意外错误。切换到UTF-8可能解决了底层解析问题，从而使类导入能够正常运行。
