No mapping found for HTTP request with URI… in DispatcherServlet with name [duplicate]

Answer 1

Add @Controller to your controller or where ever you have the @RequestMapping for you json end point.

This worked for me while deploying a similar application.

Answer 2

Please check your [PROJECT_NAME]\target\classes directory to see whether myController.class is generated or not.

If not, please check all your java source code whether there are any compilation errors.

Answer 3

addition of <mvc:annotation-driven/> worked for me. Add it before line <context:component-scan ............/>

Answer 4

If you depend on Spring Social, check that you have configured a Web Controller bean:

import org.springframework.context.annotation.Bean;
import org.springframework.social.connect.web.ConnectController;
import org.springframework.social.connect.ConnectionFactoryLocator;
import org.springframework.social.connect.ConnectionRepository;

...

@Bean
public ConnectController connectController(ConnectionFactoryLocator connectionFactoryLocator, ConnectionRepository connectionRepository) {
    return new ConnectController(connectionFactoryLocator, connectionRepository);
}

Answer 5

If you are using Java code based on Spring MVC configuration then enable the DefaultServletHandlerConfigurer in the WebMvcConfigurerAdapter object.

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

Answer 6

What is /Elso?

You try:

@RequestMapping("/Elso")
public class myController {

    @RequestMapping("/hello")
    public ModelAndView helloWorld() {

        String message = "Hello World, Spring 3.0!";
        return new ModelAndView("hello", "message", message); 
    }
}
