Im trying to convert my spring mvc project into spring boot. I converted all necessary files according to spring boot.There are no errors on console. But when i run my web app in browser im getting this error.

No mapping found for HTTP request with URI [/onlineshopping/WEB-INF/views/page.jsp] in DispatcherServlet with name 'dispatcherServlet'

any url i try to run im getting the same error why?

OnlineshoppingApplication.java

    package net.kzn.onlineshopping;

Please tell me what am i doing wrong here?

My problem solved after adding this configuration

@Override

public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) {

    configurer.enable();

}

after adding this configuration white page error stopped but jsp page code started showing as html so added these two dependancies.

JSP file not rendering in Spring Boot web application

Your view resolver doesn't seem to have a viewclass for handling jsps. Try setting the viewclass in you AppConfig.java

/** View resolver for JSP */

@Bean

public ViewResolver getViewResolver(){

    InternalResourceViewResolver resolver = new InternalResourceViewResolver();

    resolver.setViewClass(JstlView.class);

    resolver.setPrefix("/WEB-INF/views/");

    resolver.setSuffix(".jsp");

    return resolver;

}
