最近在使用JSP讀取MySQL數(shù)據(jù)庫的過程中，遇到了亂碼的問題。
經(jīng)過反復(fù)的實(shí)驗(yàn)和研究，發(fā)現(xiàn)主要原因是JSP頁面和MySQL數(shù)據(jù)庫之間的字符編碼不一致。相信很多人都曾經(jīng)遇到過這種問題，下面我將分享一下我如何解決這個問題：
<%@ page language="java" pageEncoding="UTF-8"%><%request.setCharacterEncoding("UTF-8"); %><%@page import="java.sql.*"%><%@ page import="java.io.*,java.util.*" %>JSP MySQL Database Connection <%
Connection conn = null;
Statement stmt = null;
ResultSet rs = null;
String url = "jdbc:mysql://localhost:3306/test";
String username = "root";
String password = "123456";
String sql = "select * from user";
try {
Class.forName("com.mysql.jdbc.Driver").newInstance();
conn = DriverManager.getConnection(url,username,password);
stmt = conn.createStatement();
rs = stmt.executeQuery(sql);
while(rs.next()){
out.println(rs.getInt(1)+" ");
out.println(rs.getString(2)+" ");
out.println(rs.getString(3)+" ");
out.println(rs.getString(4)+" ");
out.println(rs.getInt(5)+"
");
}
} catch(Exception e){
e.printStackTrace();
} finally {
try {
if (rs != null) rs.close();
if (stmt != null) stmt.close();
if (conn != null) conn.close();
} catch (Exception e) {
e.printStackTrace();
}
}
%>在代碼中，我們首先要在頁面中聲明字符編碼為UTF-8，然后在JSP頁面中設(shè)置請求的字符編碼為UTF-8，還要確保數(shù)據(jù)庫的字符編碼也為UTF-8。最后，在獲取數(shù)據(jù)之前設(shè)置正確的字符編碼就可以解決亂碼問題了。
希望這篇文章對大家理解和解決JSP和MySQL編碼問題有所幫助。
