简介

Java maven项目，spring boot + mybatis + thymeleaf + Echarts。

实现目标

可以访问html。
数据可以带入html。
数据可以在Echarts中使用。

实现步骤

1.引入依赖

            <scope>test</scope>
        </dependency>
    </dependencies>

注意：打包时候需要把前端文件打包进去。如果产生无法打包问题，填入如下代码

  <build>
        <resources>
            <resource>
                    <directory>src/main/resources/static</directory>

                <targetPath>${project.build.directory}/classes/static</targetPath>
            </resource>
            <resource>
                <directory>src/main/resources/templates</directory>

                <targetPath>${project.build.directory}/classes/templates</targetPath>
            </resource>
       </resources>
</build>

2.编写后端接口

此处自由发挥即可，注意传给前端的参数。本例中传入的是list

 @RequestMapping(value = "count",method = RequestMethod.GET)
    public ModelAndView count(){
       return new ModelAndView("interface/countNumber","interfaceList",operationLogService.getInterfaceCount());
    }

3.前端接收参数

默认路径如下：

resource/static/css，resource/static/js，resource/templates/自定义（与代码中return对应，本例中interface）/html页面名称

页面代码

<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org">
<head>
    <meta charset="UTF-8"/>
    <title>接口使用统计</title>
