步骤 2 : 模仿和排错 步骤 3 : view.html
老规矩，先下载右上角的可运行项目，配置运行起来，确认可用之后，再学习做了哪些步骤以达到这样的效果。
先启动 EurekaServerApplication 跟着启动 IndexCodesApplication 然后启动 IndexDataApplication 接着启动 TrendTradingBackTestServiceApplication 随后启动 TrendTradingBackTestViewApplication 最后启动 IndexZuulServiceApplication 注： 记得运行redis-server.exe 以启动 redis 服务器 然后访问地址： http://127.0.0.1:8031/api-view/
在确保可运行项目能够正确无误地运行之后，再严格照着教程的步骤，对代码模仿一遍。
模仿过程难免代码有出入，导致无法得到期望的运行结果，此时此刻通过比较正确答案 ( 可运行项目 ) 和自己的代码，来定位问题所在。 采用这种方式，学习有效果，排错有效率，可以较为明显地提升学习速度，跨过学习路上的各个槛。 推荐使用diffmerge软件，进行文件夹比较。把你自己做的项目文件夹，和我的可运行项目文件夹进行比较。 这个软件很牛逼的，可以知道文件夹里哪两个文件不对，并且很明显地标记出来 这里提供了绿色安装和使用教程：diffmerge 下载和使用教程
数据什么的已经有了，这里只是遍历出来就行了
