Error while Handling 404 error for Spring Boot REST application

Question

I trying my hand out in Spring boot exception handling . I have created a REST application and the application works for all valid url. I am trying to handle the exceptions for invalid url. But if i try hitting the application with an invalid url , i am getting the below exception:-

13:04:02.940 [http-bio-8081-exec-3] INFO  o.s.web.servlet.DispatcherServlet - FrameworkServlet 'dispatcherServlet': initialization completed in 44 ms
13:04:03.177 [http-bio-8081-exec-3] ERROR o.s.boot.context.web.ErrorPageFilter - Cannot forward to error page for/sample/processgetMessage5 (response is committed), so this response may have the wrong status code

Being new to spring boot I am not able to figure out the reason. Any pointers or suggestion will be helpful.

Wanted to try out the options mentioned in this siteenter link description here, once i am able to remove the exception.

Any pointers on how to handle 404 with annotations in spring 4 will be very helpful.

Trying out the below code :-

@Configuration
@EnableWebMvc
@EnableSwagger
public class WebConfig extends WebMvcConfigurerAdapter {
.......

  @Bean
            public EmbeddedServletContainerCustomizer containerCustomizer() {

                return new EmbeddedServletContainerCustomizer() {
                @Override
                public void customize(ConfigurableEmbeddedServletContainer container) {

                    ErrorPage error401Page = new ErrorPage(HttpStatus.UNAUTHORIZED, "/401.html");
                    ErrorPage error404Page = new ErrorPage(HttpStatus.NOT_FOUND, "/401.html");
                    ErrorPage error500Page = new ErrorPage(HttpStatus.INTERNAL_SERVER_ERROR, "/401.html");

                    container.addErrorPages(error401Page, error404Page, error500Page);
                }
            };
        }

Adding the dependency from pom.xml

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-actuator</artifactId>
            <version>1.1.5.RELEASE</version>

                </exclusion>
            </exclusions>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>

            <exclusions>

                    <artifactId>commons-logging</artifactId>
                    <groupId>commons-logging</groupId>
                </exclusion>
            </exclusions>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-jpa</artifactId>
            <version>1.1.5.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <version>1.1.5.RELEASE</version>
            <scope>test</scope>
        </dependency>

PFB the updated stack trace:-

]

The application works fine for valid url mapping. It is build using spring boot. PFB the app annotated classes:-

    @EnableJpaRepositories
    @EnableAutoConfiguration
    public class AppConfig {


        public static void main(String[] args) {
            SpringApplication.run(AppConfig .class, args);
        }



@Configuration
@EnableWebMvc
public class WebApplicationConfig extends WebMvcConfigurerAdapter {

    @Override
    public void configureMessageConverters(
            List<HttpMessageConverter<?>> converters) {
        MappingJackson2HttpMessageConverter mappingJackson2HttpMessageConverter = new MappingJackson2HttpMessageConverter();

        converters.add(mappingJackson2HttpMessageConverter);
        converters.add(new StringHttpMessageConverter());

        super.configureMessageConverters(converters);
    }

public class WebApplicationXML extends SpringBootServletInitializer {
    @Override
    protected SpringApplicationBuilder configure(
            SpringApplicationBuilder application) {
        return application.sources(Application.class);
    }   

}

It works for me with a simple 404. Maybe it's time to share the whole project and some steps to reproduce? — Dave Syer, Sep 02 '14 at 13:58
I got something to work, though not completely. After removing @EnableWebMvc, i am not getting the error. I am getting forwared to the default Whitemarker page. — Manu, Sep 04 '14 at 11:48

I have added the mapping to redirect to custom html pages if a 404 happens. PFB the changes done for this:

Removed the Annotation @EnableWebMvc from the WebConfig.java class. This is done to remove the error “response already committed”, on trying any invalid url.

Add the below code in WebConfig.java class and the revenant html pages:

@Bean
public EmbeddedServletContainerCustomizer containerCustomizer() {

    return new EmbeddedServletContainerCustomizer() {
        @Override
        public void customize(ConfigurableEmbeddedServletContainer container) {

            ErrorPage error401Page = new ErrorPage(HttpStatus.UNAUTHORIZED,
                    "/401.html");
            ErrorPage error404Page = new ErrorPage(HttpStatus.NOT_FOUND,
                    "/404.html");
            ErrorPage error500Page = new ErrorPage(
                    HttpStatus.INTERNAL_SERVER_ERROR, "/500.html");
            ErrorPage error505Page = new ErrorPage(
                    HttpStatus.HTTP_VERSION_NOT_SUPPORTED, "/505.html");
            ErrorPage error506Page = new ErrorPage(
                    HttpStatus.METHOD_NOT_ALLOWED, "/405.html");
            container.addErrorPages(error401Page, error404Page,
                    error500Page, error505Page, error506Page);
        }
    };
}

Thanks a lot for the suggestions ans hep. It was very useful.

The stack trace still says 1.1.4. Can you update that as well if you didn't already? – Dave Syer Sep 02 '14 at 06:18
Yes Dave, I forgot to update the stack trace. I have added it now. – Manu Sep 02 '14 at 08:34
