struts2 返回 json

 

 1、action 片段

public Map responseJson;   
    public Map getResponseJson() {   
        return responseJson;   
    }   
    public void setResponseJson(Map responseJson) {   
        this.responseJson = responseJson;   
    }

Map<String, Object> map = new HashMap<String, Object>();  
		List<Map<String, Object>> list = new ArrayList<Map<String, Object>>();  
		
		
			Map<String, Object> m = new HashMap<String, Object>();  
			m.put("m0001",m0005.getM0001()); 
			m.put("m0002",m0005.getM0002()); 
			
			list.add(m); 

		map.put("status", 1);
		map.put("M0005List", list);
		this.setResponseJson(map);

 

2、struts2 XML

<package name="shopManagerJson" extends="json-default" namespace="/shopManagerJson">
		<action name="*"
			class="com.mall.shop.action.ShopAction" method="{1}">
			<result type="json">
				<!-- 这里指定将被Struts2序列化的属性，该属性在action中必须有对应的getter方法 -->
				<param name="root">responseJson</param>
			</result>
			</action>
	</package>

 

 

3、js

$.post(postUrl,{gid:goodsId,num:goodsNum,sid:shopid},function(data){
	         			
	         			if(data.status){

	         				tdTemp.empty();
	         				
	         				$.each(data.M0005List,function(i, item){
	         		           
	         		           tdTemp.append('<td bgcolor="#ffffff" align="center" style="width:250px;" valign="middle"><a href="<%=basePath%>goodsManager/toFindGoodsPage.do?id='+item.m0003+'" target="_blank"><img style="width:50px; height:50px;" src="<%=basePath%>photo/'+item.m0010+'" border="0"><br>'+item.m0007+'</a> </td>');
	         		          tdTemp.append('<input name="goodsId" type="hidden" value="'+item.m0003+'"><input name="sid" type="hidden" value="'+item.m0001+'">');
	         		         tdTemp.append('<td bgcolor="#ffffff" align="center">'+item.m0004+' <br></td>');
	         		         tdTemp.append('<td align="center" bgcolor="#ffffff"><span class="price">'+item.m0008.toFixed(1)+'</span></td>');
	         		         tdTemp.append('<td align="center" bgcolor="#ffffff"><input class="min" name="" type="button" value="-"> <input type="text" name="" id="goods_number" readonly="readonly" value="'+item.m0005+'" size="4" class="text_box" style="text-align:center "> <input class="add" name="" type="button" value="+"> </td>');
	         		        tdTemp.append('<td align="center" bgcolor="#ffffff"><span class="priceSmallTotal">'+item.m0006.toFixed(1)+'</span></td>');
	         		       tdTemp.append('<td align="center" bgcolor="#ffffff"><a href="javascript:if (confirm(\'您确实要把该商品移出购物车吗？\')) location.href=\'<%=basePath%>shopManager/delM0005.do?id='+item.m0001+'\';">删除</a></td>');
	         		          

	         		        
	         		        });
	         		        
	         				
	         			}else{
	         				alert('获取失败！');
	         				window.location.reload();
	         			}
	         			
	         		},'json');
