我在 SprintBoot 2 上配置了一个数据库连接（HikariCP）。我在application.properties 中定义了 poolName ：

spring.datasource.hikari.poolName=HikariConnectionPool

我想监视空闲 DB 连接的数量，所以我尝试创建一个线程来监视 DB 连接：

public class HikariCPStatistics implements Runnable {

    public static final Logger logger = LoggerFactory.getLogger(HikariCPStatistics.class);

    private static HikariPoolMXBean poolProxy;

    public HikariCPStatistics() {
            MBeanServer mBeanServer = ManagementFactory.getPlatformMBeanServer();
            try {

                    poolProxy = JMX.newMXBeanProxy(mBeanServer, poolName, HikariPoolMXBean.class);

            } catch (MalformedObjectNameException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
            }
    }

    @Override
    public void run() {
            logger.info("Starting Connection Pool status monitor");
            while ( true ) { …
