Spring - RestController dispatcher - spring

Question

in order to get my basic rest-api (only GET) working, i created this setup:
web.xml:
<?xml version="1.0" encoding="UTF-8"?>
<web-app
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://java.sun.com/xml/ns/javaee"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
version="3.0">
<display-name>app</display-name>
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
<servlet>
<servlet-name>app</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>app</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
</web-app>
next i have this api controller:
package packagename.controller.api;
import java.util.concurrent.atomic.AtomicLong;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;
import packagename.model.Home;
#RestController
public class HomeApiController {
#RequestMapping("/api/home")
public Home greeting() {
return new Home(1, "asdas");
}
}
and the actual Home model:
package packagename.model;
public class Home {
private final long id;
private final String content;
public Home(long id, String content) {
this.id = id;
this.content = content;
}
public long getId() {
return id;
}
public String getContent() {
return content;
}
}
When i create the war file and put it into the webapps folder of my tomcat server, i open "localhost:8080/webappname/api/home".
Next i get 404-error, but i have no idea why.
Anybody could help me with this setup?
Thanks and Greetings!

You've mixed spring boot with traditional web application.
RestController is enough and there is no need to specify a web.xml.
What you need is removing web.xml and add dependency spring-boot-starter-tomcat and marking it as provided and change packaging to war and configuring war plugin continue without a web.xml.
And document http://docs.spring.io/spring-boot/docs/1.4.0.BUILD-SNAPSHOT/reference/htmlsingle/#build-tool-plugins-maven-packaging could help.
Please let me know if any question.
