米巴蒂蒂斯等于“一巴蒂斯”的标签是什么?
原标题:What is the MyBatis equivalent to the iBatis <isParameterPresent> tag?

我正在携带一些老的“iBatis”版本2? 如何取代<代码><isParailepresent>tag? 我读到。 MyBatis用户指南,并知道你能够做一个<if test=”>,但我不知道如何提及参数物体? 它是否有特殊的名称? 是否有不同的标签?

最佳回答

由此可见,有一个称为“参数”的特别变量。 它没有出现在用户指南中,但应当有。 然后,你可以测试这一变量,使之无效。

因此,更换<代码><isParailepresent> 是<if test=”_para amount != 无”>
