Question

I have been using the new feature of Spring 3.1.1 the “java based configuration”.
I have faced an issue while creating a small demo to test that new concept.

When I deploy my “springway.war” over tomcat ,when I request “http://localhost:8080/springway/” –> I gout “HTTP Status 404”

I am sure that I missing something but I couldn’t figure it out .
I have been looking at the “GreenHouse” example that is over Spring site but I still get the same issue.

Here is my WebConfig.java :

package config;

import java.util.List;

import javax.inject.Inject;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.support.ReloadableResourceBundleMessageSource;
import org.springframework.core.env.Environment;
import org.springframework.http.converter.HttpMessageConverter;
import org.springframework.http.converter.json.MappingJacksonHttpMessageConverter;

import org.springframework.validation.Validator;
import org.springframework.validation.beanvalidation.LocalValidatorFactoryBean;

import org.springframework.web.multipart.MultipartResolver;
import org.springframework.web.multipart.commons.CommonsMultipartResolver;
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.WebMvcConfigurer;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
import org.springframework.web.servlet.view.UrlBasedViewResolver;
import org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer;
import org.springframework.web.servlet.view.freemarker.FreeMarkerView;
import org.springframework.web.servlet.view.tiles2.TilesConfigurer;
import org.springframework.web.servlet.view.tiles2.TilesView;

@Configuration
@EnableWebMvc
public class WebConfig extends WebMvcConfigurerAdapter {

    @Inject
    private Environment environment;

    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/resources/**").addResourceLocations("/resources/");
    }

    public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
        converters.add(new MappingJacksonHttpMessageConverter());
    }


    /**
     * ViewResolver configuration required to work with Tiles2-based views.
     */
    @Bean
    public ViewResolver viewResolver() {
        UrlBasedViewResolver viewResolver = new UrlBasedViewResolver();
        viewResolver.setViewClass(FreeMarkerView.class);
        return viewResolver;
    }

    /**
     * Configures Tiles at application startup.
     */
    @Bean
    public TilesConfigurer tilesConfigurer() {
        TilesConfigurer configurer = new TilesConfigurer();
        configurer.setDefinitions(new String[]{
                "/WEB-INF/layouts/tiles.xml",
                "/WEB-INF/views/**/tiles.xml"
        });
        configurer.setCheckRefresh(true);
        return configurer;
    }

//    @Bean
//    public FreeMarkerConfigurer freeMarkerConfigurer() {
//        FreeMarkerConfigurer configurer = new FreeMarkerConfigurer();
//        configurer.setTemplateLoaderPath(
//
//                "/WEB-INF/views/**/freemarker.xml");
////        configurer.set(true);
//        return configurer;
//    }

    @Bean
    public MultipartResolver multipartResolver() {
        CommonsMultipartResolver multipartResolver = new CommonsMultipartResolver();
        multipartResolver.setMaxUploadSize(500000);
        return multipartResolver;
    }
}

And the web.xml:

Answer 1

The issues I have faced have been resolved.
I have resolved the isse of scanning the controllers via
“@ComponentScan(“my.package.containing.controllers.to.scan”)”

You can see the demo here: http://refile.net/f/?o8v
