本文整理了Java中org.springframework.jdbc.core.JdbcTemplate.setQueryTimeout()方法的一些代码示例，展示了JdbcTemplate.setQueryTimeout()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。JdbcTemplate.setQueryTimeout()方法的具体详情如下：
包路径：org.springframework.jdbc.core.JdbcTemplate
类名称：JdbcTemplate
方法名：setQueryTimeout

JdbcTemplate.setQueryTimeout介绍

[英]Set the query timeout for statements that this JdbcTemplate executes.

Default is -1, indicating to use the JDBC driver's default (i.e. to not pass a specific query timeout setting on the driver).

Note: Any timeout specified here will be overridden by the remaining transaction timeout when executing within a transaction that has a timeout specified at the transaction level.
[中]设置此JdbcTemplate执行的语句的查询超时。
默认值为-1，表示使用JDBC驱动程序的默认值（即不传递驱动程序上的特定查询超时设置）。
注意：在事务级别指定了超时的事务内执行时，此处指定的任何超时将被剩余的事务超时覆盖。
