JDBC 数据库连接超时和查询超时控制问题 - ITeye问答
DriverManager.setLoginTimeout();
Statement.setQueryTimeout();
不起作用
问题补充：chen_yongkai 写道引用Oracle&& JDBC&& does&& not&& support&& login&& timeouts.&& Calling&& the&& static&& DriverManager.setLoginTimeout()&& method&& will&& have&& no&& effect
找了个ojdbc15.jar，可以，但是mysql的还是不行。。
问题补充：chen_yongkai 写道引用void setQueryTimeout(int seconds)
&&&&&&&&&&&&&&&&&&&& throws SQLException将驱动程序等待 Statement 对象执行的秒数设置为给定秒数。如果超过该限制，则抛出 SQLException。
参数：
seconds - 以秒为单位的查询超时限制；零表示没有任何限制
有没有把时间单位搞错了？
setQueryTimeout方法用oracle、mysql测试，可以。
问题补充：chen_yongkai 写道还与数据库的驱动程序有关系，你用的是什么驱动（jar包）？
mysql5.1的jar包还是不行，通过设置connectiontimeout参数可以实现，但不是想要的结果，不知道针对不同数据库jdbc驱动有没有统一的实现方法来控制连接超时？
采纳的答案
引用不知道针对不同数据库jdbc驱动有没有统一的实现方法来控制连接超时？ 应该没有统一的方法，这和数据库厂商的接口有关系，也没有形成统一的标准。

　　由异常来看，是由于MongoDB连接超时造成的。于是，往MongoDB上找原因。首先上MongoDB的配置文件：
mongodb.replica-set=192.98.12.242:.12.245:30007
mongodb.hostname=192.98.12.245
mongodb.port=30007
mongodb.connections-per-host=1000
mongodb.threads-allowed-to-block-for-connection-multiplier=200
mongodb.connect-timeout=2000
mongodb.max-wait-time=2000
mongodb.auto-connect-retry=true
mongodb.socket-keep-alive=true
mongodb.socket-timeout=1500
mongodb.slave-ok=true
mongodb.write-number=1
mongodb.write-timeout=1000
mongodb.write-fsync=true
mongodb.dbname=shardvectordb
mongodb.dbuser=
mongodb.dbpassword=
　　连接时间2秒。然后在定位mongodb的查询，结果为6、7秒。原来是这个原因。然后定位，一个查询为什么耗时那么久呢？
经过排查，原来是查询字段没有创建索引。然后把索引创建，查询几十毫秒，ok问题全部解决。
