mysql有中文版的吗？

呵呵,这简单,把jar放到classpath里,就是当你用MyEclipse建一个web工程时,放在webapps下的WebRoot的WEB-INF/lib就可以了,就相当于引用到classpath里,就可以用MyEclipse写代码了,一般都是写一个DB类,以后就可以重复使用这个类了。你可以上网找一些视频来看看,尚学堂讲的视频不错,都是基础的 

给你一个例子:
import java.sql.*;

public class DB {
 public static Connection getConn() {
 Connection conn = null;
 try {
 Class.forName("com.mysql.jdbc.Driver");
 conn = DriverManager.getConnection("jdbc:mysql://localhost/test?user=root&password=root");
 } catch (ClassNotFoundException e) {
 e.printStackTrace();
 } catch (SQLException e) {
 e.printStackTrace();
 }

 return conn;
 }

 public static PreparedStatement prepare(Connection conn, String sql) {
 PreparedStatement pstmt = null; 
 try {
 if(conn != null) {
 pstmt = conn.prepareStatement(sql);
 }
 } catch (SQLException e) {
 e.printStackTrace();
 }
 return pstmt;
 }

 public static PreparedStatement prepare(Connection conn, String sql, int autoGenereatedKeys) {
 PreparedStatement pstmt = null; 
 try {
 if(conn != null) {
 pstmt = conn.prepareStatement(sql, autoGenereatedKeys);
 }
 } catch (SQLException e) {
 e.printStackTrace();
 }
 return pstmt;
 }

 public static Statement getStatement(Connection conn) {
 Statement stmt = null; 
 try {
 if(conn != null) {
 stmt = conn.createStatement();
 }
 } catch (SQLException e) {
 e.printStackTrace();
 }
 return stmt;
 }

 /*
 public static ResultSet getResultSet(Connection conn, String sql) {
 Statement stmt = getStatement(conn);
 ResultSet rs = getResultSet(stmt, sql);
 close(stmt);
 return rs;
 }
 */

 public static ResultSet getResultSet(Statement stmt, String sql) {
 ResultSet rs = null;
 try {
 if(stmt != null) {
 rs = stmt.executeQuery(sql);
 }
 } catch (SQLException e) {
 e.printStackTrace();
 }
 return rs;
 }

 public static void executeUpdate(Statement stmt, String sql) {
 try {
 if(stmt != null) {
 stmt.executeUpdate(sql);
 }
 } catch (SQLException e) {
 e.printStackTrace();
 }
 }

 public static void close(Connection conn) {
 try {
 if(conn != null) {
 conn.close();
 conn = null;
 }
 } catch (SQLException e) {
 e.printStackTrace();
 }
 }

 public static void close(Statement stmt) {
 try {
 if(stmt != null) {
 stmt.close();
 stmt = null;
 }
 } catch (SQLException e) {
 e.printStackTrace();
 }
 }

 public static void close(ResultSet rs) {
 try {
 if(rs != null) {
 rs.close();
 rs = null;
 }
 } catch (SQLException e) {
 e.printStackTrace();
 }
 }

 public static void main(String[]args) throws SQLException {
 Statement stmt = getStatement(getConn());
 String sql = "select * from user";
 ResultSet rs = getResultSet(stmt,sql);
 while(rs!=null&&rs.next()) {
 System.out.println(rs.getString(2));
 }
 }
}
