mysql、postgresql、druid链接池踩坑记录

The last packet successfully received from the server wIs 10,010 milliseconds ago. The last packet sent successfully to the server was 10,010 milliseconds ago.### The error may exist in URL 

mysql 链接字符串没有 &connectTimeout=600000&socketTimeout=600000 导致查询超过10秒就报错了

org.postgresql.util.PSQLException: An I/O error occurred while sending to the backend.

postgresql是同样的问题，报错不一样，也是10秒超时。postgresql链接字符串加了&connectTimeout=600000&socketTimeout=600000这个不生效。发现druid这个玩意也是个坑

不管datasource.setSocketTimeout()给多少值根本就不生效 在datasource.getConnection()的时候就会更新成 10000 

最后用 HikariDataSource就没问题。

HikariConfig config = new HikariConfig();config .setJdbcUrl(url);config .setUsername(username);config .setPassword(password);config .setDriverClassName(driverClass);// 设置连接池属性config.setMaximumPoolSize(10);config.setMinimumIdle(5);config.setIdleTimeout(30000);return new HikariDataSource(config);
