Openshift MySQL UTF-8編碼

Question

我得到了問題，以正確的UTF-8編碼插入字符串到MySQL數據庫。字符串未正確插入。我在網上發現了這個問題的很多解決方案，但在Openshift上我沒有任何效果。我可以在我的本地服務器上正確插入它，但不能在雲配置中插入。這裏是我的問題：

從EJB I'm插入：Přílišžluťoučký坤像素ďábelskéODY

但MySQL的存儲：P裏？ ？lu？ou？k？k ?? 2 P升belsk

我用的PaaS雲Openshift，JBoss應用服務器7時，MySQL 5.5

這裏是我的代碼：？

1. 的MySQL：數據庫，表和colums已設置正確的排序規則：utf8_czech_ci

   mysql> SHOW VARIABLES LIKE'％character％';

Variable_name     Value 

character_set_client   utf8 

character_set_connection  utf8 

character_set_database  utf8 

character_set_filesystem  binary 

character_set_results   utf8 

character_set_server   utf8 

character_set_system   utf8 

character_sets_dir   /opt/rh/mysql55/root/usr/share/mysql/charsets 

2.jsp

<form role="form" method="post" action="MakeRezervationServlet"> 
        <input type="hidden" name="term" value="${param.termin}"/> 
        <div class="form-group"> 
         <label for="userName">Startovní lokace</label> 
         <input type="text" name="startLocation" value="U autoskoly" class="form-control" id="exampleInputEmail1" > 
        </div> 
        <div class="form-group"> 
         <label for="userName">Poznámka</label> 
         <input type="text" name="note" class="form-control" id="exampleInputEmail1" placeholder="Zde můžete zanechat vzkaz pro instruktora" > 
        </div> 
        <button type="submit" class="btn btn-success">Potvrdit termín</button> 

3.Servlet。我發現通過測試，該字符串中的Servlet OK，沒有servlet和JSP

package application.servlets; 

import java.io.IOException; 

import javax.ejb.EJB; 
import javax.servlet.ServletException; 
import javax.servlet.annotation.WebServlet; 
import javax.servlet.http.HttpServlet; 
import javax.servlet.http.HttpServletRequest; 
import javax.servlet.http.HttpServletResponse; 
import javax.servlet.http.HttpSession; 

import application.ejb.RezervationLocal; 


@WebServlet("/MakeRezervationServlet") 
public class MakeRezervationServlet extends HttpServlet { 
    private static final long serialVersionUID = 1L; 

@EJB 
private RezervationLocal rezervation; 

public MakeRezervationServlet() { 
    super();  
} 

protected void processRequest(HttpServletRequest request, HttpServletResponse response) 
     throws ServletException, IOException { 

    response.setContentType("text/html;charset=UTF-8"); 
    request.setCharacterEncoding("UTF-8"); 

    String note = request.getParameter("note"); 
    byte[] n = note.getBytes("ISO8859_1"); 
    note = new String(n, "UTF-8"); 

    String startLocation = request.getParameter("startLocation"); 
    byte[] startLoc = startLocation.getBytes("ISO8859_1"); 
    startLocation = new String(startLoc, "UTF-8"); 

    String term = request.getParameter("term"); 
    int idTerm = Integer.valueOf(term); 

    HttpSession session = request.getSession(); 
    String IDuser; 
    int intIDuser; 

    synchronized (session) { 
     IDuser = (String) session.getAttribute("IDuser"); 
     intIDuser = Integer.valueOf(IDuser); 
    } 

    //hardcode předává konstantního instruktora id=3 
    String message = rezervation.makeRezervation(idTerm, intIDuser, 3, startLocation, note); 
    request.setAttribute("message", message); 
    request.getRequestDispatcher("kalendar.jsp").forward(request, response); 
} 


@Override 
protected void doGet(HttpServletRequest request, HttpServletResponse response) 
     throws ServletException, IOException { 
    processRequest(request, response); 
} 

@Override 
protected void doPost(HttpServletRequest request, HttpServletResponse response) 
     throws ServletException, IOException { 
    processRequest(request, response); 
} 


@Override 
public String getServletInfo() { 
    return "Short description"; 
} 

}

1. EJB之間的問題。我發現通過測試，同樣在EJB是字符串仍處於JDBC URL確定

   package application.ejb; 
   
   import java.sql.Connection; 
   import java.sql.Connection; 
   import java.sql.PreparedStatement; 
   import java.sql.ResultSet; 
   import java.sql.SQLException;

   import javax.sql.DataSource; 
   import javax.ejb.LocalBean; 
   import javax.ejb.Stateless; 
   import javax.naming.Context; 
   import javax.naming.InitialContext; 
   
   @Stateless 
   @LocalBean 
   public class Rezervation implements RezervationLocal { 
   
   @EJB 
   private LoggerBeanLocal loggerBean; 
   @EJB 
   private UtilityBeanLocal utilityBean; 
   
   public Rezervation() { 
       // TODO Auto-generated constructor stub 
   } 
   
   @Override 
   public String makeRezervation(int idTerm, int idStudent, int idInstructor, String startLocation, String note) { 
       String message = ""; 
       Connection conn = null; 
       PreparedStatement stat = null; 
       ResultSet rs = null; 
   
       try { 
        try { 
         conn = connect(); 
        } catch (Exception e) { 
         // TODO Auto-generated catch block 
         e.printStackTrace(); 
        } 
        synchronized (conn) { 
         stat = conn.prepareStatement("SELECT ID_TERM FROM TBL_TERMS WHERE ID_STUDENT = ? AND ID_TYPE_OF_STATUS <= 2 ORDER BY ID_TERM"); 
         stat.setInt(1, idStudent); 
         rs = stat.executeQuery(); 
   
         Boolean podminka1 = false; 
         Boolean podminka2 = false; 
   
         int counter = 0; 
         String term2 = String.valueOf(idTerm); 
         term2 = term2.substring(0, 8); 
         String term; 
   
         while (rs.next()) { 
   
          term = String.valueOf(rs.getInt("ID_TERM")); 
          term = term.substring(0, 8); 
          if (term.equals(term2)) { 
           podminka1 = true; 
          } 
   
          counter++; 
          if (counter == 14) { 
           podminka2 = true; 
          } 
   
         } 
         if (podminka1) { 
          message = "Nelze rezervovat více jízd ve stejný den."; 
         } else if (podminka2) { 
          message = "Nelze rezervovat více jízd. Již máte absolvováno nebo rezervováno všech 14 jízd."; 
         } else { 
   
          stat = conn.prepareStatement("INSERT INTO TBL_TERMS (ID_TERM, ID_STUDENT, ID_INSTRUCTOR, START_LOCATION, NOTE, ID_TYPE_OF_STATUS) VALUES(?,?,?,?,?,?)"); 
          stat.setInt(1, idTerm); 
          stat.setInt(2, idStudent); 
          stat.setInt(3, idInstructor); 
          stat.setString(4, startLocation); 
          stat.setString(5, note); 
          stat.setInt(6, 1); 
          stat.execute(); 
          String date = utilityBean.parseDate(idTerm); 
          message = "Termín " + date + " byl uložen"; 
          loggerBean.log(idStudent, "made rezervation "+idTerm); 
         } 
        } 
   
       } catch (SQLException ex) { 
        message = "Termín nebyl uložen: " + ex.toString(); 
   
       } finally { 
   
        try { 
         if (rs != null) { 
          rs.close(); 
         } 
         if (stat != null) { 
          stat.close(); 
         } 
         if (conn != null) { 
          conn.close(); 
         } 
        } catch (SQLException e) { 
        } 
       } 
       return message; 
   } 
   
   public Connection connect() throws Exception { 
       String jndiName = "java:jboss/datasources/MysqlDS"; 
       Connection con = null; 
       Context ic = new InitialContext(); 
       Object obj = ic.lookup(jndiName); 
       javax.sql.DataSource ds = (javax.sql.DataSource) obj; 
       con = ds.getConnection();   
       return con; 
   } 
   

   }

5.standalone.xml -I使用//...?useUnicode=true &的characterEncoding = UTF-8

任何幫助讚賞。我已經花了很多時間來解決這個問題。由於
