I am very new to Spring. I am trying to build a MVC application using Spring Boot which shows a list of products. But i am getting the below error:
javax.servlet.ServletException: Circular view path [products]: would dispatch back to the current handler URL [/products] again. Check your ViewResolver setup! (Hint: This may be the result of an unspecified view, due to default view name generation.)
Here is controller:
package com.springframeworkguru.controllers;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import com.springframeworkguru.services.ProductService;
@Controller
public class ProductController {
private ProductService productService;
@Autowired
public void setProductService(ProductService productService) {
this.productService = productService;
}
@RequestMapping("/products")
public String listProducts(Model model){
model.addAttribute("products", productService.listAllProducts());
return "products";
}
}
This is the main class:
package com.springframeworkguru;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.context.web.SpringBootServletInitializer;
import com.springframeworkguru.controllers.ProductController;
@SpringBootApplication
public class SpringmvcApplication extends SpringBootServletInitializer{
public static void main(String[] args) {
SpringApplication.run(SpringmvcApplication.class, args);
}
}
and products.html:

<tr th:each="product : ${products}">

<td th:text="${product.imageUrl}"></td>
<td><a th:href="${'/product/' + product.id}">View</a> </td>
</tr>
</table>
</div>
</div>
</body>
</html>
The products.html is in /static folder. Also, I am using Eclipse Kepler.
