关于hikari链接释放和mysql空闲链接问题

项目描述:

springboot2+hikari,配置连接池大小是15,连接空闲时间1分钟,池中连接的最长生命周期是10分钟。

图片说明

1:当项目启动,会创建15个连接,此时使用mysql命令“SHOW STATUS LIKE 'Threads%'; ”看到Threads_connected增加了15个

2:10分钟后,控制台看到这些输出
图片说明

3:继续查看mysql连接数为30,又增加了15个

4:每隔十分钟mysql连接增加15个

5:停止项目运行,控制台输出为
图片说明

6:查看mysql连接数15个,减少了15个

疑问:为什么10分钟后执行了Closing connection命令,而数据库连接数并没有减少?停止项目运行,同样执行了Closing connection命令,数据库连接释放了

关闭实例不对,必须对hikaricp提供的连接实例调用close(),

如何理解hikari数据库连接中的maximumpoolSize?

数据库连接池,如何理解最大连接数这个值呢?关于hikari数据库连接池,网上的计算公式是cpu核心数*2+硬盘数,如果值设置为15,是不是意味着同一时刻最多只能有15个用户进行访问呢?有谁能讲解一下吗,十分感谢。

MySQL驱动从mysql-connector-java6.0.6升级到8.0.11后使用load datalocal infile出现的问题

我们之前的MySQL驱动是6.0.6的,现在升级到8.0.11后,别的问题没有,就在插入大量数据时出现了问题,我们使用的是load datalocal infile插入的; 以下是出现问题的代码: ``` try { if(inputStream == null){ logger.info("InputStream is null ,No data is imported"); return 0; } conn = jdbcTemplate.getDataSource().getConnection(); statement = conn.prepareStatement(sql); if (statement.isWrapperFor(Statement.class)) { com.mysql.cj.jdbc.ServerPreparedStatement mysqlStatement = statement.unwrap(com.mysql.cj.jdbc.ServerPreparedStatement.class); mysqlStatement.setLocalInfileInputStream(inputStream); result = mysqlStatement.executeUpdate(); } return result; } catch (Exception e) { logger.info("批量插入eda数据异常,原因: " + e.getMessage()); } ``` 这个是出现的报错信息: ``` 批量插入eda数据异常,原因: Unable to unwrap to class com.mysql.cj.jdbc.ServerPreparedStatement ``` 查了好久都没有找到解决办法,各位大神帮忙啊,感激不尽

springboot1.5 设置mysql utf8mb4 需要mysql 的字符集也为utf8mb4 吗

现mysql 版本为5.5.40,字符集为utf8。 springboot 1.5 连接mysql 时只在配置文件中修改为 ``` datasource:     tomcat:         init-s-q-l: SET NAMES utf8mb4 COLLATE utf8mb4_unicode_ci ``` 保存emoji 表情时依旧报错。 如果mysql 默认字符集没有修改为utf8mb4,只在springboot 配置中将字符集设置为utf8mb4 是不生效的么?
