Java獲取漢字拼音或拼音首字母

在進行模糊查詢時，經常用到使用漢字拼音或者首字母進行匹配查詢。以下是獲取漢字拼音或者首字母的java代碼實現

jdbc訪問數據庫

1 將數據庫的JDBC驅動加載到classpath中，在基于JAVAEE的WEB應用實際開發過程中，通常要把目標數據庫產品的JDBC驅動復制到WEB-INF/lib下.
2 加載JDBC驅動，并將其注冊到DriverManager中；
3 建立數據庫連接，取得Connection對象.例如:
MySQL：
    String Driver="com.mysql.jdbc.Driver";    //驅動程序
    String URL="jdbc:mysql://localhost:3306/db_name";    //連接的URL,db_name為數據庫名
    String Username="username";    //用戶名
    String Password="password";    //密碼
    Class.forName(Driver).new Instance();
    Connection con=DriverManager.getConnection(URL,Username,Password);

Microsoft SQL Server驅動(msbase.jar、mssqlserver.jar、msutil.jar):
    String Driver="com.microsoft.jdbc.sqlserver.SQLServerDriver";    //連接SQL數據庫的方法
    String URL="jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=db_name";    //db_name為數據庫名
    String Username="username";    //用戶名
    String Password="password";    //密碼
    Class.forName(Driver).new Instance();    //加載數據驅動
    Connection con=DriverManager.getConnection(URL,UserName,Password);

Microsoft SQL Server驅動(jtds-1.2.jar):
    String Driver="net.sourceforge.jtds.jdbc.Driver";    //連接SQL數據庫的方法
    String URL="jdbc:jtds:sqlserver://localhost:1433/db_name;s=8.0;lastupdatecount=true";    //db_name為數據庫名
    String Username="username";    //用戶名
    String Password="password";    //密碼
    Class.forName(Driver).new Instance();    //加載數據驅動
    Connection con=DriverManager.getConnection(URL,UserName,Password);

Sysbase:
    String Driver="com.sybase.jdbc.SybDriver";    //驅動程序
    String URL="jdbc:Sysbase://localhost:5007/db_name";    //db_name為數據可名
    String Username="username";    //用戶名
    String Password="password";    //密碼
    Class.forName(Driver).newInstance();
    Connection con=DriverManager.getConnection(URL,Username,Password);

Sysbase:
  String url="jdbc:sybase:Tds:localhost:5007/tsdata";
  Properties sysProps=System.getProperties();
  SysProps.put("user","userid");
  SysProps.put("password","user_password");
  Connection conn=DriverManager.getConnection(url,SysProps);

Oracle(用thin模式):
    String Driver="oracle.jdbc.driver.OracleDriver";    //連接數據庫的方法
    String URL="jdbc:oracle:thin:@loaclhost:1521:orcl";    //orcl為數據庫的SID
    String Username="username";    //用戶名
    String Password="password";    //密碼
    Class.forName(Driver).newInstance();    //加載數據庫驅動
    Connection con=DriverManager.getConnection(URL,Username,Password);

PostgreSQL:
    String Driver="org.postgresql.Driver";    //連接數據庫的方法
    String URL="jdbc:postgresql://localhost/db_name";    //db_name為數據可名
    String Username="username";    //用戶名
    String Password="password";    //密碼
    Class.forName(Driver).newInstance();
    Connection con=DriverManager.getConnection(URL,Username,Password);

DB2：
    String Driver="com.ibm.db2.jdbc.app.DB2.Driver";    //連接具有DB2客戶端的Provider實例
    //String Driver="com.ibm.db2.jdbc.net.DB2.Driver";    //連接不具有DB2客戶端的Provider實例
    String URL="jdbc:db2://localhost:5000/db_name";    //db_name為數據可名
    String Username="username";    //用戶名
    String Password="password";    //密碼
    Class.forName(Driver).newInstance();
    Connection con=DriverManager.getConnection(URL,Username,Password);

Informix:
    String Driver="com.informix.jdbc.IfxDriver";
    String URL="jdbc:Informix-sqli://localhost:1533/db_name:INFORMIXSER=myserver";    //db_name為數據可名
    String Username="username";    //用戶名
    String Password="password";    //密碼
    Class.forName(Driver).newInstance();
    Connection con=DriverManager.getConnection(URL,Username,Password);

JDBC-ODBC:
    String Driver="sun.jdbc.odbc.JdbcOdbcDriver";
    String URL="jdbc:odbc:dbsource";    //dbsource為數據源名
    String Username="username";    //用戶名
    String Password="password";    //密碼
    Class.forName(Driver).newInstance();
    Connection con=DriverManager.getConnection(URL,Username,Password);

4 建立Statement對象或PreparedStatement對象.例如：
//建立Statement對象
Statement stmt=conn.createStatement();
//建立ProparedStatement對象
String sql="select * from user where userName=? and password=?";
PreparedStatement pstmt=Conn.prepareStatement(sql);
pstmt.setString(1,"admin");
pstmt.setString(2,"liubin");
5 執行SQL語句.例如：
String sql="select * from users";
ResultSet rs=stmt.executeQuery(sql);
//執行動態SQL查詢
ResultSet rs=pstmt.executeQuery();
//執行insert update delete等語句，先定義sql
stmt.executeUpdate(sql);
6 訪問結果記錄集ResultSet對象。例如：
while(rs.next)
{
out.println("你的第一個字段內容為："+rs.getString());
out.println("你的第二個字段內容為："+rs.getString(2));
}
7 依次將ResultSet、Statement、PreparedStatement、Connection對象關閉，釋放所占用的資源.例如:
rs.close();
stmt.clost();
pstmt.close();
con.close();
