我花了几个小时来解决我的问题，但没有大的结果，也许有人会帮助我 :)
我的项目是这样的:
我想使用一个库来绘制本教程中的图表: FusionCharts
我收到这样的错误信息:
09-Jan-2018 21:56:22.304 WARNING [http-nio-8080-exec-1] org.springframework.web.servlet.PageNotFound.noHandlerFound No mapping found for HTTP request with URI [/] in DispatcherServlet with name 'spring' 09-Jan-2018 21:56:22.323 WARNING [http-nio-8080-exec-3] org.springframework.web.servlet.PageNotFound.noHandlerFound No mapping found for HTTP request with URI [/] in DispatcherServlet with name 'spring' 09-Jan-2018 21:56:22.465 WARNING [http-nio-8080-exec-5] org.springframework.web.servlet.PageNotFound.noHandlerFound No mapping found for HTTP request with URI [/] in DispatcherServlet with name 'spring'
文件 FusionCharts、fusioncharts.charts.js 和 fusioncharts.js 来自库。
家庭 Controller 代码:

}
public String chartmaker(){
FusionCharts lineChart = new FusionCharts (
"line",// chartType
"chart1",// chartId

return lineChart.render();

当我运行一个项目时，我收到了这条消息:
当我去 http://localhost:8080/welcome.html我有一个清晰的屏幕，这个库没有绘制任何图表或类似的东西。
我的配置文件是 web.xml 还是 spring-servlet.xml？ 我将不胜感激任何建议
问候， 阿德里安
最佳答案
我建议您使用 @Controller 注释您的 HomeController 类，并在具有任何名称的方法内(例如 public String showIndex() { return "index "; })。使用 @GetMapping("/") 注释该方法应该有效。
