public String saveAdd() {try {goodsManager.add(goods);this.msgs.add("商品添加成功");this.urls.put("商品列表", "goods!list.do");} catch (RuntimeException e) {e.printStackTrace();this.msgs.add(e.getMessage());}return this.MESSAGE;}

message.jsp页面：

<div    class='success'><c:forEach var="msg" items="${msgs}">  <h4>${msg }</h4></c:forEach>       <div style="clear:both;">   <c:forEach var="url" items="${urls}">           <a href="${url.value}" target="_self" >    返回${url.key}  </a>    </c:if>    </c:forEach>   </div></div>
