### 1、下载Echarts ###

### 2、添加echarts.js到项目中 ###

在resources目录下创建js目录，然后将刚才下载的echarts.js文件放到js目录下。

不知道为什么我在IntelliJ IDEA工具下，创建对应的js目录失败，出现“static.js”或者“static.css”目录。只好删除之前失败的目录“static.js”，然后重新在resources下创建static目录、js目录、css目录，再将js目录和css目录拖入static目录即可。

### 3、查看Echarts官方样例 ###

进入http://echarts.baidu.com/tutorial.html  
参考“5 分钟上手 ECharts”

### 4、参考上面样例代码，编写测试程序 ###

在template目录下创建测试页面echarts.html

<!DOCTYPE html>
    <html xmlns:th="http://www.thymeleaf.org">
    <head>
        <meta charset="UTF-8">
        <title>测试Echarts</title>
        
        <script type="application/javascript" th:src="@{js/echarts.js}"></script>
    </head>
    <body>
    
    <div id="main" style="width: 600px;height:400px;"></div>
    <script type="text/javascript">
        // 基于准备好的dom，初始化echarts实例
        var myChart = echarts.init(document.getElementById('main'));
    
        // 指定图表的配置项和数据
        var option = {
            title: {
                text: 'ECharts 入门示例'
            },
            tooltip: {},
            legend: {
                data:['销量']
            },
            xAxis: {
                data: ["衬衫","羊毛衫","雪纺衫","裤子","高跟鞋","袜子"]
            },
            yAxis: {},
            series: [{
                name: '销量',
                type: 'bar',
                data: [5, 20, 36, 10, 10, 20]
            }]
        };
    
        // 使用刚指定的配置项和数据显示图表。
        myChart.setOption(option);
    </script>
    </body>
    </html>

创建控制器

package cn.hadron.eba.controller;
    import org.springframework.stereotype.Controller;
    import org.springframework.ui.Model;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.ResponseBody;
    
    @Controller
    public class IndexController {
    
        @RequestMapping("/echarts")
        public String echarts(Model model){
            System.out.println("IndexController.echarts");
            return "echarts";
        }
    
    }

### 5、运行效果 ###
