When you do, MyBatis will automatically wrap it in a Map, and key it by name. List instances will be keyed to the name “list” and array instances will be keyed to the name “array”.</blockquote> 可以传递一个List或Array类型的对象作为参数,MyBatis会自动的将List或Array对象包装到一个Map对象中,List类型对象会使用list作为键名,而Array对象会用array作为键名。 集合类型通常用于构造IN条件，sql映射文件中使用foreach元素来遍历List或Array元素。 mapper接口: <table border="0" style='border-collapse: collapse;
