Configure ViewResolver with Spring Boot and annotations gives No mapping found for HTTP request with URI error

Question

I\'m trying to make \"hello world\" application with gradle, spring boot and spring mvc with the simplest view resolver and html.

I started from the thymeleaf spring

Answer 1

View resolver can also be configured in application.properties file of Spring-Boot web applications, something like below:

spring.mvc.view.prefix=/WEB-INF/jsp/
spring.mvc.view.suffix=.jsp

Answer 2

After investigating more I discovered an alternative solution that works without adding configureDefaultServletHandling method. You need to add an embedded tomcat jsp engine to build.gradle:

compile("org.apache.tomcat.embed:tomcat-embed-jasper")

As opposed to configureDefaultServletHandling method this solution works not only with plain html but also with jsp.

All solutions are available at: https://github.com/driver-pete/spring-mvc-example This solution is available on master. Biju's solution is on DefaultServletHandling_solution branch.

Answer 3

You only need to enable the default servlet, this is done by adding the following to your MvcConfiguration:

@Configuration
@EnableWebMvc
public class MvcConfiguration extends WebMvcConfigurerAdapter{
    @Bean
    public ViewResolver getViewResolver() {
        InternalResourceViewResolver resolver = new InternalResourceViewResolver();
        resolver.setPrefix("/WEB-INF/");
        resolver.setSuffix(".html");
        return resolver;
    }

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

Essentially what is happening is Spring does not know how to handle the handling of such content natively(could be a jsp say), and to this configuration is the way to tell it to delegate it to the container.
