示例1: persist
import io.netty.buffer.ByteBuf; //导入方法依赖的package包/类
@Override
public void persist(String exchangeName, Binding binding) throws BrokerException {
Connection connection = null;
PreparedStatement statement = null;
try {
connection = getConnection();
statement = connection.prepareStatement(RDBMSConstants.PS_INSERT_BINDING);
statement.setString(1, exchangeName);
statement.setString(2, binding.getQueue().getName());
statement.setString(3, binding.getRoutingKey());
FieldTable arguments = binding.getArguments();
byte[] bytes = new byte[(int) arguments.getSize()];
ByteBuf byteBuf = Unpooled.wrappedBuffer(bytes);
byteBuf.resetWriterIndex();
arguments.write(byteBuf);
statement.setBytes(4, bytes);
statement.executeUpdate();
connection.commit();
} catch (SQLException e) {
throw new BrokerException("Error occurred while storing binding " + binding, e);
} finally {
close(connection, statement);
}
}
