警告:建议不要在没有服务器身份验证的情况下建立SSL连接
Gri*_*dis 8 java mysql ssl servlets
您好我试图通过使用eclipse和tomcat的java servlet连接到mysql数据库,但是我采取了以下错误:"警告:不建议在没有服务器身份验证的情况下建立SSL连接".我添加了"useSSL = false？" 到连接URL但仍然得到相同的错误.任何建议？servlet的代码是:
package com.simpleWebApplication.servlet;
import java.io.IOException;
import java.io.PrintWriter;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
@WebServlet("/register")
public class RegisterServlet extends HttpServlet {
private static final long serialVersionUID = 1L;
/**
* @see HttpServlet#HttpServlet()
*/
public RegisterServlet() {
super();
// TODO Auto-generated constructor stub
}
protected void doPost(HttpServletRequest request, HttpServletResponse
response)
throws ServletException, IOException {
doGet(request, response);
response.setContentType("text/html");
PrintWriter out = response.getWriter();
String idusers = request.getParameter("0");
String name = request.getParameter("name");
String surname = request.getParameter("surname");
String gender = request.getParameter("gender");
String birthdate = request.getParameter("birthdate");
String workAddress = request.getParameter("workAddress");
String homeAddress = request.getParameter("homeAddress");
try{
Class.forName("com.mysql.jdbc.Driver");
Connection con = DriverManager.getConnection("jdbc:mysql://localhost:3306/mysys?autoReconnect=true&useSSL=false","root","pass");
PreparedStatement ps = con.prepareStatement("insert into Users values(?,?,?,?,?,?)");
ps.setString(1, idusers);
ps.setString(2, name);
ps.setString(3, surname);
ps.setString(4, gender);
ps.setString(5, birthday);
ps.setString(6, workAddress);
ps.setString(7, homeAddress);
int i=ps.executeUpdate();
if(i>0)
{
out.println("You are sucessfully registered");
}
}
catch(Exception se)
{
se.printStackTrace();
}
}
}
这是与servlet连接的register.jsp页面.

堆栈错误:
Wed Sep 28 08:58:53 EEST 2016 WARN: Establishing SSL connection without server's identity verification is not recommended. According to MySQL 5.5.45+, 5.6.26+ and 5.7.6+ requirements SSL connection must be established by default if explicit option isn't set. For compliance with existing applications not using SSL the verifyServerCertificate property is set to 'false'. You need either to explicitly disable SSL by setting useSSL=false, or set useSSL=true and provide truststore for server certificate verification.
