tomcat runs smoothly, there aren't errors or warnings in editor, , brings browser 404 - home.jsp not found.
i've got code running on wildfly 10 , after dropped home.jsp /src/main/webapp/ directory served content.

edit:
and confirm you, downloaded tomcat 9.0.0.m19 , receiving 404 when request http://localhost:8080/springtest-0.0.1-snapshot/. i'll give 8 quick whirl.
edit 2:
tomcat 8.5.13 returns 404 well. . . . both 8.5 , 9 support servlet 3 spec, i'm guessing there's wrinkle in there somewhere when collides these newer spring features. found spring java config: tomcat deploy without web.xml , http://docs.spring.io/autorepo/docs/spring-framework/4.3.x/javadoc-api/org/springframework/web/webapplicationinitializer.html notes that:
mapping '/' under tomcat
apache tomcat maps internal defaultservlet "/", , on tomcat versions <= 7.0.14, servlet mapping cannot overridden programmatically. 7.0.15 fixes issue. overriding "/" servlet mapping has been tested under glassfish 3.1.
i did try changing mapping / /home , tomcat still wasn't happy (wildfly was).
more edits come if find anything.
edit 3:
umm. well, i'm bit gobsmacked. tested tomcat 9, instead of requesting http://localhost:8080/springtest-0.0.1-snapshot/ try going http://localhost:8080/springtest/. home.jsp, above, code works!
edit 4 (sigh):
for completeness , perhaps because i'm using eclipse, had add 2 bits of maven build plugin configuration:
<build> <plugins> <plugin> <groupid>org.apache.maven.plugins</groupid> <artifactid>maven-compiler-plugin</artifactid> <version>3.5.1</version> <configuration> <source>1.8</source> <target>1.8</target> </configuration> </plugin> <plugin> <groupid>org.apache.maven.plugins</groupid> <artifactid>maven-war-plugin</artifactid> <version>3.0.0</version> <configuration> <failonmissingwebxml>false</failonmissingwebxml> </configuration> </plugin> </plugins> </build> i wouldn't expect these affect if haven't previously.
