Question

我正在尝试使用百日咳和弹簧启动在表格中动态创建行。

我查看了以下网址，但无法让它为我工作。

http://forum.thymeleaf.org/I-have-problem-in-binding-the-list-of-objects-contained-inside-a-object-on-the-form-using-thymeleaf-td3525038.html#a3526497

http://stingh711.github.io/dynamic-form-with-springmvc-and-thymeleaf.html

当我点击addCourse按钮时，它甚至没有进入StudentController。

请有人帮忙吗？
