削除処理
変更と同じように一覧でItemnのcodeをhiddenで渡してActionを呼び出します。
<s:if test="#session['user'].delete_priv == true">
<td>
<s:form action="Delete_select">
<s:hidden name="code"/>
<s:submit key="button.delete"/>
</s:form>
</td>
</s:if> 削除のJSP

</html>削除のActionではcodeに該当するItemをDBから削除し、再度SubListを抜き出して、一覧表示JSPに遷移します。
@Action(
value = "/Delete_execute",
results = {
@Result(name = "execute", location = "/WEB-INF/form/retrieveResultForm.jsp" )
}
)
public String execute() throws Exception {
int deletedNumber = iService.deleteItem(item.getCode());
HttpServletRequest request = ServletActionContext.getRequest();
rdManager.deleteItemInList(request, item);
return "execute";
}deleteItemメソッド
@Override
public void deleteItemInList(HttpServletRequest request, Item item) {
HttpSession session = request.getSession();
List<Item> subList = (List<Item>) session.getAttribute("items");
int i = 0;
for(Item delItem: subList) {
if(delItem.getCode() == item.getCode()) {
subList.remove(i);
break;
}
i++;
}
int currentPage = (Integer)request.getSession().getAttribute("currentPage");
getRetrieveSubList(request, currentPage);
}
