首先我怀疑是不是获取到连接时直接就失效了.

版本

druid: 1.0.26
mysql: 5.1.44

配置

DruidDataSource dataSource = new DruidDataSource();
dataSource.setInitialSize(5);
dataSource.setMinIdle(5);
dataSource.setMaxWait(60000);
dataSource.setValidationQuery("select 1");
dataSource.setMaxActive(30);
dataSource.setTestWhileIdle(true);
dataSource.setTestOnBorrow(false);
dataSource.setTestOnReturn(false);
dataSource.setRemoveAbandoned(true);
dataSource.setTimeBetweenEvictionRunsMillis(60000);
dataSource.setMinEvictableIdleTimeMillis(300000);
dataSource.setPoolPreparedStatements(true);
dataSource.setMaxPoolPreparedStatementPerConnectionSize(20);
String connectionInitSqls = "SET NAMES utf8mb4";
StringTokenizer tokenizer = new StringTokenizer(connectionInitSqls, ";");
dataSource.setConnectionInitSqls(Collections.list(tokenizer));
return dataSource;

异常

它们用的同一把锁 <0x00000000870b7690> (a com.mysql.jdbc.JDBC4Connection)

导致连接无法回收, 直到满八个小时才被回收.

有什么建议不？谢谢。
