Question

当我得到以下输出时：

System.out.print(name);

我无法正确看到这些角色。

我该如何解决？

这是我的代码：

insert.jsp

<%@page import="dao.DaoAdmin"%>
<%@ page import="java.sql.*"%>
<%@ page import="java.sql.PreparedStatement;"%>
<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
    <%    request.setCharacterEncoding("UTF8");   %>
<%
    String name = request.getParameter("name");
    String city = request.getParameter("city");
    String phone = request.getParameter("phone");
    System.out.print(name);
%>

Answer 1

我不知道它是否会对你有所帮助，但我在你的代码insert.jsp中注意到的是你在编写这段代码：

<%
    String name = request.getParameter("name");
    String city = request.getParameter("city");
    String phone = request.getParameter("phone");
    System.out.print(name);
%>

甚至在您开始<html>代码之前。此代码应位于<body> ...</body>标记中的某个位置。

其次，为什么要编写具有不同属性的多个<%@page ..>标记。

<%@page import="dao.DaoAdmin"%>
<%@ page import="java.sql.*"%>
<%@ page import="java.sql.PreparedStatement;"%>
<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<%    request.setCharacterEncoding("UTF8");   %>

而是像这样写：

<%@page import="dao.DaoAdmin;java.sql;java.sql.PreparedStatement" language="java"
contentType="text/html; charset=UTF-8" />

所以试试这个。

Answer 2

尝试在开头添加response.setCharacterEncoding ("UTF-8");。
