问题 There is a way to specify IBatis query timeout using oracle jdbc and Java? Thanks 回答1: From the iBatis manual : in the <settings> element : defaultStatementTimeout (iBATIS versions 2.2.0 and later) This setting is an integer value that will be applied as the JDBC query timeout for all statements. This value can be overridden with the “statement” attribute of any mapped statement. If not specified, no query timeout will be set unless specified on the “statement” attribute of a mapped statement
