I am trying to setup a boneCP connection and I am getting the following error message:
Exception in thread "main" java.lang.ClassCastException: com.jolbox.bonecp.StatementHandle cannot be cast to com.mysql.jdbc.Statement
The connection seems to work fine but I get stopped out at the query.
Here is my code:
BoneCP connectionPool = null;
Connection connection = null;
try {
// load the database driver (make sure this is in your classpath!)
Class.forName("com.mysql.jdbc.Driver");
} catch (Exception e) {
e.printStackTrace();
return;
}
try {
// setup the connection pool
BoneCPConfig config = new BoneCPConfig();
config.setJdbcUrl("jdbc:mysql://192.126.0.0:3306/"); // jdbc url specific to your database, eg jdbc:mysql://127.0.0.1/yourdb
config.setUsername("root");
config.setPassword("");
config.setMinConnectionsPerPartition(5);
config.setMaxConnectionsPerPartition(10);
config.setPartitionCount(1);
connectionPool = new BoneCP(config); // setup the connection pool
connection = connectionPool.getConnection(); // fetch a connection
if (connection != null){
System.out.println("Connection successful!");
Statement stmt = (Statement) connection.createStatement();
ResultSet rs = stmt.executeQuery("SELECT 1 FROM table"); // do something with the connection.
while(rs.next()){
System.out.println(rs.getString(1)); // should print out "1"'
}
}
connectionPool.shutdown(); // shutdown connection pool.
} catch (SQLException e) {
e.printStackTrace();
} finally {
if (connection != null) {
try {
connection.close();
} catch (SQLException e) {
e.printStackTrace();
}
}
}
