如何迭代对象的数组列表

Question

我使用的是dao设计模式，其中我返回了一个arraylist对象，在对象内部我可以通过将对象类型转换为类来获取对象，并像object.getName（）那样获取getter，我想使用jstl标签进行编程。我该怎么做。

Answer 1

<c:forEach items="${yourArrayList}" var="item">
    <c:out value="${item.name}" />
</c:forEach>

The objects you put in your collection should conform to the JavaBeans specification (for ex. all of their properties should be accessible via getter methods).

${yourArrayList} is actually a request attribute that you have put from a servlet and then forwarded to the jsp.

Answer 2

Ok with Bozho.

I will just say that if you redirect a servlet to jsp (which is better than calling dao from scriptlets...) don't forget to put your object that will be used in jstl in a pagecontext scope like request or session. Without that jstl lib would never find your object...
