I'm fairly new to Spring mvc and would like to make annotation configuration for my app. No web.xml or anything like this. I have written two jsp pages, that I would like to access, two controller classes and one application class with main method as shown below:
import javax.servlet.ServletContext;
import javax.servlet.ServletRegistration;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.context.web.SpringBootServletInitializer;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.WebApplicationInitializer;
import org.springframework.web.servlet.DispatcherServlet;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
@Configuration
@ComponentScan
@EnableAutoConfiguration
@EnableWebMvc
public class Application extends SpringBootServletInitializer implements WebApplicationInitializer{
static final Logger logger = LoggerFactory.getLogger(Application.class);
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(Application.class);
}
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
Example of controller:
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.servlet.ModelAndView;
@Controller
public class IndexController {
static final Logger logger = LoggerFactory.getLogger(IndexController.class);
@RequestMapping(value = {"/index","/"})
@ResponseBody
public ModelAndView index()
{
return new ModelAndView("index");
}
}
and finally my pom.xml which I edited a bit

When I try to access my jsp pages thorugh localhost:8080/index i get :
19:08:36.344 [main] INFO o.s.b.c.e.t.TomcatEmbeddedServletContainer - Tomcat started on port(s): 8080/http
19:08:36.346 [main] INFO p.e.u.d.s.service.Application - Started Application in 5.493 seconds (JVM running for 6.496)
19:08:42.571 [http-nio-8080-exec-1] INFO o.a.c.c.C.[Tomcat].[localhost].[/] - Initializing Spring FrameworkServlet 'dispatcherServlet'
19:08:42.571 [http-nio-8080-exec-1] INFO o.s.web.servlet.DispatcherServlet - FrameworkServlet 'dispatcherServlet': initialization started
19:08:42.615 [http-nio-8080-exec-1] INFO o.s.web.servlet.DispatcherServlet - FrameworkServlet 'dispatcherServlet': initialization completed in 44 ms
19:08:42.651 [http-nio-8080-exec-1] WARN o.s.web.servlet.PageNotFound - No mapping found for HTTP request with URI [/index] in DispatcherServlet with name 'dispatcherServlet'
Can anyone could provide any help on this issue? I suspect that I should inject a bean with DispatcherServlet but I don't really know where to go with that and how to set it up properly.
Add follow configuration upon webMvcConfig.java
