HTTP Status 404 - Using Spring+Tomcat

Question

I am beginner to Spring and I am working on my learning project. With below code, I can view the index.jsp but not test.jsp. I use Spring 4.0.1+ Tomcat 7.0.52 + STS 3.4.0.

Webapp.java

package springweb;

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

public class Webapp extends AbstractAnnotationConfigDispatcherServletInitializer {
    @Override
    protected Class<?>[] getRootConfigClasses() {
        return new Class<?>[0];
    }

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

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

IndexController.java

package springweb.controller;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class IndexController {
    private static final Logger logger = LoggerFactory.getLogger(IndexController.class);
    @RequestMapping(value="/")
    public String index() {
        logger.info("Welcome Index!");
        return "index";
    }
}

TestController.java

package springweb.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.RequestMethod;

@Controller
public class TestController {
    private static final Logger logger = LoggerFactory.getLogger(TestController.class);
    @RequestMapping(value="/test/", method = RequestMethod.GET)
    public String test() {
        logger.info("Welcome test!");
        return "test";
    }
}

WebConfig.java

package springweb;

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.EnableWebMvc;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
import org.springframework.web.servlet.view.InternalResourceViewResolver;
import org.springframework.web.servlet.view.JstlView;

@Configuration
@EnableWebMvc
@ComponentScan(basePackages={"springweb.controller"})
public class WebConfig extends WebMvcConfigurerAdapter {
    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/resources/**").addResourceLocations("/resources/");
    }

    @Bean
    public ViewResolver viewResolver() {

        InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
        viewResolver.setViewClass(JstlView.class);
        viewResolver.setPrefix("/WEB-INF/jsp/");
        viewResolver.setSuffix(".jsp");
        return viewResolver;
    }
}

Answer 1

Simple answer for 100% free xml:

1. Set property for the DispatcherServlet

    public class SpringMvcInitializer extends AbstractAnnotationConfigDispatcherServletInitializer { @Override protected Class<?>[] getRootConfigClasses() { return new Class[] { RootConfig.class }; } @Override protected Class<?>[] getServletConfigClasses() { return new Class[] {AppConfig.class }; } @Override protected String[] getServletMappings() { return new String[] { "/" }; } //that's important!! @Override protected void customizeRegistration(ServletRegistration.Dynamic registration) { boolean done = registration.setInitParameter("throwExceptionIfNoHandlerFound", "true"); // -> true if(!done) throw new RuntimeException(); } } 

2. Create @ControllerAdvice:

    @ControllerAdvice public class AdviceController { @ExceptionHandler(NoHandlerFoundException.class) public String handle(Exception ex) { return "redirect:/404"; } @RequestMapping(value = {"/404"}, method = RequestMethod.GET) public String NotFoudPage() { return "404"; } } 

that's all
