struts2 中的嵌套循环

其中：

public class Stockin{

private Integer id;

private String stockInId;

private Date stockInDate;

private String stockInType;

private String batchNo;

private String createBy;

private Date createTime;

private String vendor;

private String status;

private String remark;

private Set goodsstockins = new HashSet(0);

.......省略set 和get

}

public class Goodsstockin{

   

private Integer id;

private Stockin stockin;

private String productName;

private String shelfName;

private int qty;

}

而在action中获取到：private List allStockin;

这时想在前台页面上获取allStockin中迭代中goodsstockins中的值代码如下：
