Spring Boot viewResolver not working - not mapping to given location

问题

I am developing spring boot application for learning.

@Override
public void configureViewResolvers(ViewResolverRegistry registry) {
    InternalResourceViewResolver resolver = new InternalResourceViewResolver();
    resolver.setPrefix("/views/");
    resolver.setSuffix(".jsp");
    registry.viewResolver(resolver);
}

I have configured my view resolver as given above. And below is the API endpoint for page

@RequestMapping(value = "/",method = RequestMethod.GET)
public ModelAndView homePage(){
    ModelAndView modelAndView = new ModelAndView();
    modelAndView.setViewName("index");
    return modelAndView;
}

But when i hit this api, i am unable to get a response. I get 404 and error i get on console is No mapping found for HTTP request with URI [/WEB-INF/views/index.jsp] in DispatcherServlet with name 'dispatcherServle

How can i fix this ?

回答1:

for people struggling with issues like this - the Spring Boot documentation states here that JSPs are not supported when running in embeddable servlet container - i.e. when using JAR packaging.

when using WAR packaging, the suggestion given in the answers here should work - but check that in the final WAR there is a directory at root: WEB-INF/views, with your JSPs

回答2:

the view path is wrong /WEB-INF/view/ instead /view/

@Override
public void configureViewResolvers(ViewResolverRegistry registry) {
    InternalResourceViewResolver resolver = new InternalResourceViewResolver();
    resolver.setPrefix("/WEB-INF/views/");
    resolver.setSuffix(".jsp");
    registry.viewResolver(resolver);
}

or you can use the application.properties located in /resources/ instead

and add these properties

spring.mvc.view.prefix: /WEB-INF/views/
spring.mvc.view.suffix: .jsp

important: the jsp views should be in /resources/ directory
