Spring REST always return 404 Not Found

Ive setup a simple REST API using Spring 4 with Spring security

web.xml

<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/mysabisabi-servlet.xml,
classpath*:META-INF/spring/applicationContext.xml,
classpath*:META-INF/spring/mysabisabi-security.xml
</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<servlet>
<servlet-name>mysabisabi-rest</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

</servlet>
<servlet-mapping>
<servlet-name>mysabisabi-rest</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>


AccountController.java

@RestController
@RequestMapping(value="/api")
public class AccountController {


@RequestMapping(value="/update", method=RequestMethod.POST)
public ResponseEntity<GenericResponse> updateRegistrationToken(@RequestBody RegistrationToken token){
GenericResponse response = new GenericResponse();
//some code here

return new ResponseEntity<GenericResponse>(response, HttpStatus.ACCEPTED);
}

}


mysabisabi-servlet.xml

<bean id="jacksonObjectMapper" class="com.mysabisabi.mapper.JsonCustomMapper" />

//dataSource configuration


LOG File

2016-07-16 16:24:45 INFO RequestMappingHandlerMapping:537 - Mapped "{[/api/update],methods=[POST]}" onto public org.springframework.http.ResponseEntity<com.mysabisabi.dto.response.GenericResponse> com.mysabisabi.controller.AccountController.updateRegistrationToken(com.mysabisabi.dto.request.RegistrationToken)


When I tried to access
http://localhost:8080/mysabisabi/api/update
I got
HTTPStatus 404 Not Found - The requested resource is not available


I've tried both
/
and
/*
as url-pattern but still the same.

Can someone point out what did I miss?

Thanks.

Answer

your configuration looks fine. Change below code in web.xml.

<servlet> <servlet-name>mysabisabi-rest</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/mysabisabi-servlet.xml</param-value> </init-param>    <load-on-startup>1</load-on-startup> </servlet>

Also check below Url. Order of loading contextConfigLocation in web.xml of Spring Servlet project
