用MyBatis进行查询,传入参数只有一个时(非Map)如int,报错 There is no getter for property named 'sleevetype' in 'class java.lang.Integer 解决方法一: 原因在于测试条件写法有误, <if test="sleevetype==0"><!-- 专属 --> exclusive=1 </if> <if test="sleevetype!=0"
总是记不住向方法中传数组参数的语法,所以记录一下. func calculateStatistics(scores:[Int]) -> (min:Int,max:Int,sum:Int) { var min = scores[] var max = scores[] var sum = for score in scores { if score>max { max=score } else if score<min{ min=score } sum += score } return
