Controller:

package com.prizy.controller;


import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;

import com.prizy.model.Product;
import com.prizy.service.ProductService;

@RestController
public class ProductController {

    @Autowired
    private ProductService productService;

    @RequestMapping("/products")
    public List<Product> getAllProducts() {
        return productService.getAllProducts();
    }

    @RequestMapping("/hi")
    public String getString() {
        return "Hi";
    }

    @RequestMapping("/products/{productId}")
    public Product getProduct(@PathVariable int productId){     
        return productService.getTopic(productId);
    }

    @RequestMapping(method=RequestMethod.POST, value="/products")
    public void addProduct(@RequestBody Product product) {
        productService.addProduct(product);
    }

    @RequestMapping(method=RequestMethod.PUT, value="/products/{productId}")
    public void updateProduct(@RequestBody Product product, @PathVariable int productId) {
        productService.updateProduct(product,productId);
    }

    @RequestMapping(method=RequestMethod.DELETE, value="/products/{productId}")
    public void deleteProduct(@PathVariable int productId) {
        productService.deleteProduct(productId);
    }

}

Main Class is

package com.prizy;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;


@EnableAutoConfiguration
@SpringBootApplication
public class ProductApiApplication {

    public static void main(String[] args) {
        SpringApplication.run(ProductApiApplication.class, args);
    }
}

Answer 1

After trying all the scenario I have finally changed the Spring boot version to 1.3.2.RELEASE

After doing this its working fine. I am still trying to get the answer why its not working on 1.5.2 Release.

But to resolve this error, i did below change to my POM.xml file

    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>1.3.2.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>

After this change , I can see the request mapping urls in logs too:

2017-04-19 11:10:49.785  INFO 4236 --- [           main] s.w.s.m.m.a.RequestMappingHandlerMapping : Mapped "{[/hello]}" onto public java.lang.String com.epic.controllers.TestController.sayHello()
2017-04-19 11:10:49.786  INFO 4236 --- [           main] s.w.s.m.m.a.RequestMappingHandlerMapping : Mapped "{[/helloss]}" onto public java.lang.String com.epic.TestControllerTest.sayHello()
2017-04-19 11:10:49.789  INFO 4236 --- [           main] s.w.s.m.m.a.RequestMappingHandlerMapping : Mapped "{[/error]}" onto public org.springframework.http.ResponseEntity<java.util.Map<java.lang.String, java.lang.Object>> org.springframework.boot.autoconfigure.web.BasicErrorController.error(javax.servlet.http.HttpServletRequest)

Please note that meanwhile I changed the mapping urls names so it may not be same as the question.

Answer 2

check the web.xml file is available or not into src>main>webapp>WEB-INF>web.xml. if not available the craete this file and use the below code.

 <servlet>
    <servlet-name>myServlet</servlet-name>
 <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:ApplicationContext.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
    <servlet-name>myServlet</servlet-name>
    <url-pattern>/api/*</url-pattern>
</servlet-mapping>

<filter>
    <filter-name>encoding-filter</filter-name>
    <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
    <init-param>
        <param-name>encoding</param-name>
        <param-value>UTF-8</param-value>
    </init-param>
    <init-param>
        <param-name>forceEncoding</param-name>
        <param-value>true</param-value>
    </init-param>
</filter>

<filter-mapping>
    <filter-name>encoding-filter</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>
