Springboot+echarts实现可视化

人气:0

现在在做毕设,做一个电商平台日志分析系统,需要结合可视化,达到一个直观的效果

1.搭建springboot项目,maven搭建,这是项目整体架构

2.后台代码:

@RestController
@RequestMapping("/wanglk_bds")
public class VisualController {

 @Autowired
 private VisualInterface visualInterface;

 /**
 * 每一天的访问用户量
 * @return
 */
 @RequestMapping(value="/bar-simple",method=RequestMethod.GET,produces="application/json")
 @ResponseBody
 public List<DayTotal> getDateTotal(){
 List<DayTotal> all = visualInterface.getAll();

 return all;

 }
}
@Service
public class VisualInterfaceImpl implements VisualInterface {

 @Autowired
 VisualMapper visualMapper;

 @Override
 public List<DayTotal> getAll() {
 List<DayTotal> totals = visualMapper.selectAllFromTable();

 return totals;
 }
}
@Mapper
public interface VisualMapper {
 List<DayTotal> selectAllFromTable();
}
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.wanglk_bds.visual.mapper.VisualMapper">
 <resultMap id="BaseResultMap" type="com.wanglk_bds.visual.bean.DayTotal">

 <result column="date" jdbcType="VARCHAR" property="date" />
 <result column="total" jdbcType="VARCHAR" property="total" />
 </resultMap>


 <sql id="Base_Column_List">
 date,total
 </sql>

 <select id="selectAllFromTable" resultMap="BaseResultMap">
 select
 <include refid="Base_Column_List" />
 from keyword
 </select>
</mapper>

3.前端代码:

<!DOCTYPE html>
<html style="height: 100%">
 <head>
 <meta charset="utf-8">
 </head>
 <body style="height: 100%; margin: 0">

 <script type="text/javascript" src="echarts.min.js"></script>

 <script type="text/javascript" src="jquery-1.11.3.min.js"></script>
 <div id="mainChart" style="height:500px;border:1px solid #ccc;padding:10px;"></div>
 <script type="text/javascript">
 var dom = document.getElementById("mainChart");
 var myChart = echarts.init(dom);
 myChart.clear();


 $.ajax({
 method:'get',
 url:'http://localhost:8888/wanglk_bds/bar-simple',
 dataType:'json',
 success:function(data){

 var option = {
 xAxis: {
 name: '日期',
 type: 'category',
 data: [data[0].date,
 data[1].date,
 data[2].date,
 data[3].date,
 data[4].date,
 data[5].date,
 data[6].date,
 data[7].date,
 data[8].date,
 data[9].date,
 data[10].date,
 data[11].date]
 },
 yAxis: {
 name:'访问量'
 },
 series: [{

 data: [data[0].total,
 data[1].total,
 data[2].total,
 data[3].total,
 data[4].total,
 data[5].total,
 data[6].total,
 data[7].total,
 data[8].total,
 data[9].total,
 data[10].total,
 data[11].total],
 type: 'bar'
 }]
 };


 myChart.setOption(option, true);
 }
 });

 </script>


 </body>
</html>

4.总结:

代码没什么技术含量,都能写出来,但是过程中出现的错误不是每个人都有

1.后台 controller层使用的注解 restcontroller 返回json格式的数据

2.mybatis自动生成文件的xml出错,为解决,

3.前台使用echarts的时候,将echarts部分放进ajax的success函数中,

4.还有css和js代码的位置问题,加载先后顺序

5.端口问题

6.使用本地tomcat部署springboot项目
