Getting HTTP 404 Error in Eclipse project

I'm trying to learn how to run a Spring MVC project on a server (still very new at this), and I'm getting an http 404 error.. I'm using Eclipse Luna 4.4.1, Java 7, Spring 4.1.4 and Pivotal tc server 3.0.2 on a Windows 7 machine. Before I go further, let me say that I get the same 404 error when creating a simple practice project using Tomcat 7, so I think the problem is somewhere in my configuration of the servers (both in tc server and in Tomcat). Here is a screenshot showing my project directory, the servers I've tried running, and the error page: enter image description here

The program code seems fine. When I run my HomeControllerTest (which I've basically gotten from the new 4th edition of Spring in Action by Craig Walls), it compiles and passes. Where else do I need to look to troubleshoot this problem? ` package com.kwalker.practicewellness;

import org.junit.Test;
import org.springframework.test.web.servlet.MockMvc;
import static org.springframework.test.web.servlet.setup.MockMvcBuilders.*;
import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.*;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.*;

import com.kwalker.practicewellness.web.HomeController;

public class HomeControllerTest {

@Test
public void testHomePage() throws Exception {
    HomeController controller = new HomeController();
    MockMvc mockMvc = standaloneSetup(controller).build();

    mockMvc.perform(get("/")).andExpect(view().name("home"));

}

}

` Here is the HomeController class:

package com.kwalker.practicewellness.web;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

@Controller
public class HomeController {

@RequestMapping(value="/", method=RequestMethod.GET)
public String home() {
    return "home";
}
}

Here is the WellnessWebAppInitializer:

package com.kwalker.practicewellness.config;

import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer;

public class WellnessWebAppInitializer extends
    AbstractAnnotationConfigDispatcherServletInitializer {

@Override
protected Class<?>[] getRootConfigClasses() {
    return new Class<?>[] { RootConfig.class };
}

@Override
protected Class<?>[] getServletConfigClasses() {
    return new Class<?>[] { WebConfig.class };
}

@Override
protected String[] getServletMappings() {
    return new String[] { "/" };
}

}

Here is the RootConfig:

package com.kwalker.practicewellness.config;

import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.ComponentScan.Filter;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.FilterType;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;

@Configuration
@ComponentScan(basePackages={"practicewellness"}, 
            excludeFilters={@Filter(type=FilterType.ANNOTATION, value=EnableWebMvc.class)})
public class RootConfig {

}

Here is WebConfig:

package com.kwalker.practicewellness.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.ViewResolver;
import org.springframework.web.servlet.config.annotation.DefaultServletHandlerConfigurer;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
import org.springframework.web.servlet.view.InternalResourceViewResolver;

@Configuration
@EnableWebMvc
@ComponentScan("practicewellness.web")
public class WebConfig extends WebMvcConfigurerAdapter {

@Bean
public ViewResolver viewResolver() {
    InternalResourceViewResolver resolver = new InternalResourceViewResolver();
    resolver.setPrefix("/WEB-INF/views/");
    resolver.setSuffix(".jsp");
    resolver.setExposeContextBeansAsAttributes(true);
    return resolver;
}

@Override
public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) {
    configurer.enable();
}

}

Here is the home.jsp page:

<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%@ page session="false" %>
<html>
<head>
<title>Welcome</title>

Solution

  • It looks like in all your config you're using the @ComponentScan incorrectly - the base package name is missing the com.kwalker. part - my guess is that the component scan isn't picking up your home controller.

    Try updating the base package in your configs to full package name.

    Also, if you start the server in INFO logging mode you should get details of all the controller/paths that have been registered - that might shed some more light on it.
