No mapping found for HTTP request with URI [/WEB-INF/views/welcome.jsp] in DispatcherServlet with name 'dispatcherServlet'
I configured the Application and code the "DispatcherServlet" to viewResolver like this:
@Configuration
@EnableWebMvc
@ComponentScan ({"controllers"})
@EnableAutoConfiguration
@SpringBootApplication
public class Application {
@Bean
public InternalResourceViewResolver viewResolver() {
InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
viewResolver.setViewClass(JstlView.class);
viewResolver.setPrefix("/WEB-INF/views/");
viewResolver.setSuffix(".jsp");
return viewResolver;
}
public static void main(String[] args){
SpringApplication.run(Application.class, args);
}
}
Controller class to handle requests looks this:
@Controller
public class HelloControllerImpl {
@RequestMapping(value= "/welcome", method= RequestMethod.GET)
public String getWelcomePage(ModelMap model) {
model.addAttribute("message", "Spring 3 MVC - Hello World");
model.addAttribute("name", "vzateychuk");
return "welcome";
}
}
The view file: \WEB-INF\views\welcome.jsp
<html>
<body>
<h1>Hello, : ${name}</h1>
<h2>Message : ${message}</h2>
</body>
</html>
The application structure: Welcome application structure
I think that something is missing in the configuration files, but I can not see. Could you guest what is wrong and what means: "No mapping found for HTTP request with URI [/WEB-INF/views/welcome.jsp]"? Should I provide xml configuratin like dispatcher-servlet.xml or something like that? Thank you in advance.
Update: I guessing that my DispatcherServlet unable to find the appropriate view. I have tryed to completely delete /WEB-INF directory, but nothing changes. Probably something wrong with this code:
public InternalResourceViewResolver viewResolver() {
InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
viewResolver.setViewClass(JstlView.class);
**viewResolver.setPrefix("/WEB-INF/views/");**
.... Can anybody guess what can be wrong? (May it be if the anotation @EnableAutoConfiguration not allow to define viewResolver's prefix?
Answer
I did simple project similiar to yours. You can check on my github
What you have to do is:
- Rename hello.html to hello.jsp
- Check that you have all dependencies in your pom.xml. I didn't see it so I am not sure if it is wrong. Make sure you have these two dependencies:
For that point you will find the explanation here<dependency> <groupId>org.apache.tomcat.embed</groupId> <artifactId>tomcat-embed-jasper</artifactId> <scope>provided</scope> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>jstl</artifactId> <scope>provided</scope> </dependency> - Indeed, you may have a problem with launching it with IDEA Community Version. I have experienced that problem as well. What you can do is first check it using command line and maven. Execute following command:
You may also configure your IDEA to run that command. Go to Run->Edit Configuration, click green plus sign on the left side and choose Maven. Then in the "Command line" field write "spring-boot:run", press ok. And run this configuration.mvn spring-boot:run - (Optional) You also have some redundant annotations on your Application class. You can remove:
- @Configuration, because @SpringBootApplication already has it
- @EnableWebMvc, because Spring Boot adds it automatically when it sees spring-webmvc on the classpath
- @EnableAutoConfiguration, because @SpringBootApplication already has it
Note that you need @ComponentScan ({"controllers"}), because of your package structure - you have Application class in different package than your controller.
