前提用Maven搭好springMVC的框架
1、建一个jsp页面,代码如下:

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Insert title here</title>
<script type="text/javascript" src="${pageContext.request.contextPath}/js/echarts.common.min.js"></script>
<script type="text/javascript" src="${pageContext.request.contextPath}/js/jquery-1.8.3.js"></script>
</head>
<body>
<div id="chartmain" style="width: 600px;height: 400px"></div>
<script type="text/javascript">

$(function(){
var myCharts=echarts.init(document.getElementById('chartmain'));
	myCharts.setOption({
		color: ['#3398DB'],
	    title:{
	        text:'ECharts 班级成绩平均分'
	    },
	    tooltip : {
	        trigger: 'axis',
	        axisPointer : {            // 坐标轴指示器,坐标轴触发有效
	            type : 'shadow'        // 默认为直线,可选为:'line' | 'shadow'
	        }
	    },
	    legend: {
	        data: ['成绩']
	    },

	    xAxis : {
	            data : []
	        },
	    yAxis : {

	    },
	    series : [
	        {
	            name:'成绩',
	            type:'bar',
	            data:[]
	        }
	    ]
	});

		//加载时显示loading动画
		myCharts.showLoading();
		//放x轴值得数组
		var gradeName=[];
		//放y轴值得数组
		var score=[];

		//写ajax给数组存值
		 $.ajax({
	        type: "post",
	        url: "${pageContext.request.contextPath}/getGrade",     //请求发送到getStudent处
	        dataType: "json",        //返回数据形式为json
	        success: function (data) {
	            //请求成功时执行该函数内容,result即为服务器返回的json对象
	            $(data).each(function(i,e){
	            	gradeName.push(e.name);    //挨个取出班别放数组
	            	score.push(e.score);     //挨个取出分数放数组
	            });
	            myCharts.hideLoading();    //隐藏加载动画
	            myCharts.setOption({        //加载数据图表
                    xAxis: {
                        data: gradeName
                    },
                    series: [{
                        // 根据名字对应到相应的系列
                        name: '成绩',
                        type:'bar',
                        barWidth: '60%',
                        data: score,
                        itemStyle: {
							normal: {
								label: {
									show: true,       //开启显示
									position: 'top',  //在上方显示
									textStyle: {      //数值样式
										color: 'black',
										fontSize: 12
									}
								}
							}
						}

                    }]
                });

	        },
	        error: function (errorMsg) {
	            //请求失败时执行该函数
	            alert("图表请求数据失败!");
	            myCharts.hideLoading();
	        }
	    })
});
</script>

</body>

</html>

2、controller那边的代码:

@Controller
public class GradeController {
	@RequestMapping("/getGrade")
	@ResponseBody
	public List<Grade> showGradeName(){
		List<Grade> list=new ArrayList<Grade>();
		list.add(new Grade("一班","89.9"));
		list.add(new Grade("二班","90.0"));
		list.add(new Grade("三班","67.9"));
		list.add(new Grade("四班","89.9"));
		list.add(new Grade("五班","70.0"));
		list.add(new Grade("六班","67.9"));
		return list;
	}
}

3、测试结果:
使用SpringMVC、Echarts绘制柱状图:-LMLPHP
