java調用mysql存儲過程

 

public static final String DRIVER_CLASS = "com.mysql.jdbc.Driver"; //驅動名
public static final String URL = "jdbc:mysql://127.0.0.1:端口號/項目名?useUnicode=true&characterEncoding=UTF-8";
public static final String USERNAME = "root"; //用戶名
public static final String PASSWORD = "root";//密碼

//方法實現

private Map callBillCheck(String billDate) throws Exception

CallableStatement cstm = connection.prepareCall(sql); //實例化對象cstm
cstm.setString(1, billDate); // 存儲過程輸入參數
// cstm.setInt(2, 2); // 存儲過程輸入參數
cstm.registerOutParameter(2, Types.INTEGER); // 設置返回值類型 即返回值
cstm.registerOutParameter(3, Types.VARCHAR); // 設置返回值類型 即返回值
