前台主站页面

页面分析:

1.在IDEA中启动服务器

Java前端页面网状图 java前端页面模板_java

2.Hbuilder打开projectWeb项目

创建一个模板template.html

<!DOCTYPE html>
<html>
	<head>
		<meta charset="utf-8">
		<title></title>
		<script src="vue.js" type="text/javascript"></script>
		<script src="axios.min.js" type="text/javascript"></script>

	<body>
		<div id="app"></div>

	<script>
		var config={

			data:{},
			methods:{
				
			},
			mounted:function(){
				console.log("mounted()");
			}
		}
		var vue=new Vue(config);
		
	</script>
</html>

3.复制模板粘贴一个模板,F2重命名为detail.html

<!DOCTYPE html>
<html>
	<head>
		<meta charset="utf-8">
		<title></title>
		<script src="vue.js" type="text/javascript"></script>
		<script src="axios.min.js" type="text/javascript"></script>
	</head>
	<body>
		<div id="app"></div>
	</body>
	<script>
		var config={
			el:"#app",
			data:{},
			methods:{
				
			},
			mounted:function(){
				debugger;
				console.log("mounted()");
				//从首页跳转过来
				//detail.html?itemId=2
				//?itemId=2
				var parameter=location.search;
				//去掉?取后面的值
				parameter=parameter.substr(1);
				//字符串的切割
				//stringArray[0]=itemId
				//stringArray[1]=2
				var stringArray=parameter.split("=");
				//取商品的编号
				var itemId=stringArray[1]
				console.log(itemId);
			}
		}
		var vue=new Vue(config);
		
	</script>
</html>

打开浏览器测试:

调取商品

连接数据库,调取商品

<!DOCTYPE html>
<html>
	<head>
		<meta charset="utf-8">
		<title></title>
		<script src="vue.js" type="text/javascript"></script>
		<script src="axios.min.js" type="text/javascript"></script>
	</head>

			手机型号:{{item.itemName}}<br>
			价格:{{item.itemPrice}}<br>
			详细:{{item.itemDesc}}<br>
			商品评论<br />
			商品推荐<br />
		</div>
	</body>
	<script>
		var config = {
			el: "#app",
			data: {
				item: null
			},

			},
			mounted: function() {
				debugger;
				console.log("mounted()");
				//从首页跳转过来
				//detail.html?itemId=2
				//?itemId=2
				var parameter = location.search;
				//去掉?取后面的值
				parameter = parameter.substr(1);
				//字符串的切割
				//stringArray[0]=itemId
				//stringArray[1]=2
				var stringArray = parameter.split("=");
				//取商品的编号
				var itemId = stringArray[1];
				console.log(itemId);
				//连接数据库调取商品数据 http://localhost:1314/item/findByItemId?id=1
				var serverUrl = "http://localhost:1314" +
					"/item/findByItemId?id=" + itemId;
				console.log(serverUrl);
				console.log(this);
				//mounted中的this代表的是vue,有item属性
				var vue = this;
				axios.get(serverUrl)
					.then(function(response) {
						debugger;
						var item = response.data;
						//this函数中,this代表的是window,没有 item属性
						//this.item=item;
						vue.item = item;
					})
					.catch(function(e) {
						window.alert("联网失败");
						//打印失败信息
						console.log(e);
					});
			}
		}
		var vue = new Vue(config);
	</script>
</html>

运行执行测试:

我们可以发现跨域调用了,调用失败

如果没有显示图片:

在IDEA项目文件目录下添加图片 projectService\src\main\resources\static
