问题描述
今天，我决定从最新的Spring 4.3官方版本切换到Spring 5.0.0.M3，这要归功于他对junit多线程内置功能的支持以及Flux gesture确实听起来很有趣.
Today I decided to switch from latest Spring 4.3 official release to spring 5.0.0.M3 thanks for his support with junit multithreading built-in possibilities and it's Flux gestion that definitely sounds really interesting.
花了整整一天的时间尝试弄清楚pom.xml为何不起作用后，我终于设法使其起作用了，至少我认为，mvn test命令运行良好，并为所有命令输出了BUILD SUCCESS我的数百个单元测试中.尽管该应用程序无法启动，但它给了我这个奇怪的错误:
After spending the whole day playing with my pom.xml trying to figure out why it wouldn't work I finally managed to make it work, at least I thought, the mvn test command runs fine and output a BUILD SUCCESS for all of my hundred of unit tests. Altough the application doesn't boot and it gives me this strange error :

我在这里和在Google上搜索时发现了一些非常相似的错误，但问题总是来自另一个bean的错误，而该错误无法通过清晰的消息启动.就我而言，它表示未设置servlet上下文，我可以理解这是有问题的，但是我不明白为什么未设置它?有人知道吗?多谢您日后的协助！
I found some pretty similar errors down here and by searching on google but the thing is it always comes from an error with another bean that couldn't be initiated with a pretty clear message. In my case it says that the servlet context wasn't set which I can understand would be problematic, however I can't understand why it didn't setup? Any one has a clue? Thanks a bunch for your future help!
下面是我的pom.xml，这肯定是所有这些的原因:

PS:很抱歉将日志作为javascript代码段放置，但我无法弄清楚如何在此处打印整个堆栈跟踪信息，除非它说我必须在每行前面添加4个空格.
PS: sorry for putting the log as a javascript snippet but I couldn't figure out how to print the whole stack trace in here without it saying that I have to add 4 spaces in front of each line.

在尝试共享一个不起作用的示例时，我发现此示例按预期工作.因此，我试图注释掉我的配置类的某些部分，并设法进行了弹簧引导.实际上，问题是以下原因: 我的Spring Configuration类扩展了WebMvcConfigurationSupport类，其中包含
While trying to share a non working example, I figured out that this one worked as expected. I therefore tried to comment some parts of my config classes and managed to make the spring boot. Actually the problem was the following : My Spring Configuration class which extended WebMvcConfigurationSupport class contained
public void addInterceptors(InterceptorRegistry registry);
出于某些自定义原因，我使用此方法添加了customHandlerInterceptor. 事实是，此拦截器是在另一个conf类中声明的bean，而我以前使用@Autowired批注在此实际类中将其获取.出于某种原因，我忽略了该功能，该功能以前可以在以前的Spring版本中使用，但现在不再可用了.通过在此类中声明了这个豆给我带来了所有这些问题，我设法使该豆不同于@Autowired批注.引导现在运行正常，但在每个请求下我都会收到404错误: 例如
I used this method to add a customHandlerInterceptor for some custom reasons. The thing is that this interceptor was a bean declared in another conf class and I used to get it in this actual class using the @Autowired annotation. For a reason I ignore, this used to work with previous Spring versions but now it doesn't anymore... I managed to get this bean differently than from @Autowired annotation by declaring this bean in this class that gave me all those problems. The boot is now running fine except at each request I get a 404 error : for example
2017-08-30 16:43:03.379 WARN 18584 --- [nio-8082-exec-4] o.s.web.servlet.PageNotFound : No mapping found for HTTP request with URI [/v1/admin/validate] in DispatcherServlet with name 'dispatcherServlet'

该映射实际上有效，但是在Spring 4.3中，它以前在每个端点名称之前都考虑了"/v1"，该参数是在application.properties中给出的，而我认为并未考虑在内.似乎新的春季版本尚不支持swagger文档插件，因为整个文档只是不加载，而是在重定向时发送404. 除此之外，我的处理程序现在还没有正确注册，但是我想这是因为我对最新的修改做错了，所以我需要先解决这个问题.
The mapping actually works but in Spring 4.3 it used to take into account "/v1" before each endpoint's name, this parameter was given in the application.properties and it's not taken into account I suppose. It seems like swagger documentation plugin isn't supported yet with new spring version because the whole documentation just doesn't load and sends a 404 instead on redirection. Other than that, my handler isn't correctly registered now but I guess it's because I've done something wrong with my latest modification so I will need to fix this first.

我已经读到某个地方，在Spring 5中，您必须用"extends WebMvcConfigurerSupport"类替换"extends WebMvcConfigurerAdapter"类，因为不赞成使用第一个类，但是这对我不起作用，我必须实现WebMvcConfigurer.现在一切都按预期工作(包括摇摇欲坠).另外，要修改contextPath，您必须在application.properties中修改此参数:"server.servlet.context-path"，而不是最后一个受支持的"server.contextPath"
I've read somewhere that in Spring 5 you have to replace the "extends WebMvcConfigurerAdapter" by "extends WebMvcConfigurerSupport" class because the first one was deprecated, however this didn't work for me and I had to implements WebMvcConfigurer instead. Now everything is working fine as expected (including swagger). Also, to modify the contextPath, you have to modify this param in your application.properties : "server.servlet.context-path" instead of last one supported "server.contextPath"
