判断 当前的 dataSource 是否关闭,如果关闭 ,抛出异常 判断fastPathPool 是否为null ,默认为null 判断当前的pool 是否为null ,如果为空,那就就行初始化,所以项目启动完了之后,第一次请求时间比较长 不为空 ,返回 result.getConnection() public Connection getConnection() throws SQLException{ if (isClosed()) {...
public DruidDataSource getDataSource(JdbcSourceInfo jdbcSourceInfo) throws SourceException { /* 省略业务代码 属性获取 */ String key = getDataSourceKey(jdbcSourceInfo); DruidDataSource druidDataSource = dataSourceMap.get(key); if (druidDataSource != null && !druidDataSource.isClosed()) { retu...

继续查,发现在dbcp在中PoolingDataSource(实现DataSource接口)调用PoolableConnection(dbcp pool相关的delegate操作)进行相应关闭时,会检查_conn.isClosed(),针对DataSource如果isClosed返回为true的则不调用returnObject,直接丢弃了链接 解释: 正因为在获取异常链接后,因为做了_conn.isClosed()判断,所以异常链接并没有返...

spring.datasource.url=jdbc:mysql://10.0.71.13:33052/appdb?socketTimeout=60000&connectTimeout=30000&serverTimezone=UTC 此后对 MySQL 可靠性场景进行多次验证,发现连接挂死的现象已经不再出现,此时问题得到解决。 四、小结 本次分享了一次关于 MySQL 连接挂死问题排查的心路历程,由于环境搭建的工作量巨大,而且...
spring.datasource.hikari.connection-timeout=30000 其中 注意到 hikari 连接池配置了 minimum-idle = 10,也就是说,就算在没有任何业务的情况下,连接池应该保证有 10 个连接。更何况当前的业务访问量极低,不应该存在连接数不够使用的情况。 除此之外,另外一种可能性则可能是出现了“僵尸连接”,也就是说在重启...
