Recently, druid monitoring is needed for maintenance of old projects, but druid is at least compatible with hibernate 4. There is no way to do this. You can do it by yourself.

Based on com.alibaba.druid.support.hibernate.DruidConnectionProvider, the ConnectionProvider interface is implemented

To use the druid data source, make the following changes

    @Override
    public void configure(Properties properties) throws HibernateException {
        String druid = properties.getProperty("druid");//Get the property file of druid and configure it in hibernate xml
        InputStream inputStream = this.getClass().getClassLoader().getResourceAsStream(druid);
        Properties druidProperties = new Properties();
        try {
            druidProperties.load(inputStream);
           // properties.putAll(druidProperties);
            /*dataSource=new DruidDataSource();
            dataSource.configFromPropety(druidProperties);*/
            dataSource = (DruidDataSource)DruidDataSourceFactory.createDataSource(druidProperties);
        } catch (IOException e) {
            e.printStackTrace();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    @Override
    public Connection getConnection() throws SQLException {
        return dataSource.getConnection();
    }

    @Override
    public void closeConnection(Connection connection) throws SQLException {
        connection.close();
    }

    @Override
    public void close() throws HibernateException {
        ((DruidDataSource)dataSource).close();;
    }

    @Override
    public boolean supportsAggressiveRelease() {
        return false;
    }
}

Later, I thought that there was an old data source in the project, so it would be better to merge the two together.

Final problem solving.

Finally, a small tip is given. If the druid connection pool is configured, and sql is not monitored, add the attribute filters:stat
