import org.apache.commons.dbcp.BasicDataSource;//此处引入类的要与xml文件中的class文件一致

@Controller
public class OptimizationTerminalLonLatController {

@Autowired
  BasicDataSource dataSource;

@RequestMapping(value = "/XXXX.XXX")
  public void demo(){
String databaseUrl = dataSource.getUrl();//url连接 
 String username = dataSource.getUsername();//用户名
    String password = dataSource.getPassword();//密码

}
}
