我在使用1.5.9版本(最新版本)的Spring Boot中显示视图文件时遇到问题.我是从Spring Initializr创建的项目.我到处搜索有关Internet的内容.我尝试了多种方法，但是无法显示视图文件，因此我决定在这里作为最后一个选择.
I have a problem at displaying view file in Spring Boot with version 1.5.9 (the latest version). I created the project from Spring Initializr. I searched everywhere about the probelm in the internet.

index.html 文件位于src/main/resources/templates文件夹中.我没有将其放在"webapp/WEB-INF/views"之类的文件夹中，因为它既旧又已弃用.Spring Boot可以处理我所假定的所有内容.您有什么建议我还能做什么?预先感谢.
index.html file is located in src/main/resources/templates folder. I did not put it in a folder like "webapp/WEB-INF/views" because it is old and deprecated. Spring Boot handles all I presume. You have any suggestion what else can I do? Thanks in advance.
推荐答案
我找到了无法解析视图的原因.我正在为那些可能遇到与我一样的问题的人撰写这篇文章，以便他们可以在此页面中使用.我看到互联网上没有有关该问题的信息.
I found the reason of not resolving view. I am writing this post for those who might have the same problem like me so they can utilize from this page. I see that there is no information regarding the problem in the internet.
我在pom.xml中包含了这两个模块
I included these two modules in pom.xml
<dependency>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-jasper</artifactId>
</dependency>
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>jstl</artifactId>
</dependency>
您可能更喜欢用Thymeleaf来做，因为这不是唯一的选择.
You can prefer doing it with Thymeleaf as this is not the only option.
