Spring, MVC and REST in two servlets

Question

Long story short: I have MVC servlet that handles requests correctly, but REST servlet seems to never handle any request, at all. Like it was not there, or requests are somehow not matched.

In more details:

My spring version is 4.2.1.

I have an application with Spring MVC, which already works. Problem is a second servlet, that I want to add, so it would handle REST requests.

This was the web.xml before I tried to add REST servlet into it (so everything worked here so far):

<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee 
     http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
     version="3.1">

    <display-name>My app</display-name>

    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/core-context.xml /WEB-INF/spring-security.xml</param-value>
    </context-param>

    <listener>
        <listener-class>
            org.springframework.web.context.ContextLoaderListener
        </listener-class>
    </listener>

    <servlet-mapping>
        <servlet-name>AccServlet</servlet-name>
        <url-pattern>*.do</url-pattern>
    </servlet-mapping>

    <welcome-file-list>
        <welcome-file>index.do</welcome-file>
    </welcome-file-list>

    <servlet>
        <servlet-name>RestServlet</servlet-name>
        <servlet-class>
            org.springframework.web.servlet.DispatcherServlet
        </servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>

    <filter>
        <filter-name>springSecurityFilterChain</filter-name>
        <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
    </filter>

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

    <session-config>
        <session-timeout>10</session-timeout>
    </session-config>
</web-app>

In few words - all requests to *.do will be handled by MVC servlet, all requests in general will pass through Spring Security.

I have a simple MVC controller to handle that:

@Controller
public class JspController {

    @Autowired
    private UserService userService;

    @RequestMapping(value = "/index.do", method = RequestMethod.GET)
    public String provideIndexModel(ModelMap model) {
        User user = userService.getLoggedUser();
        model.addAttribute("user", user.getUsername());
        if (user.getBusiness() != null) {
            model.addAttribute("business", user.getBusiness().getCompanyName());
        }
        return "index";
    }

    @RequestMapping(value = "/login.do", method = {RequestMethod.GET})
    public String provideLoginModel(ModelMap model) {
        return "login";
    }

    public UserService getUserService() {
        return userService;
    }

    public void setUserService(UserService userService) {
        this.userService = userService;
    }
}

The controller is in package scanned by proper scan declaration in servlet's context xml file.

Now, what I did to enable REST was to add following servlet to web.xml:

<servlet>
    <servlet-name>AccServlet</servlet-name>
    <servlet-class>
        org.springframework.web.servlet.DispatcherServlet
    </servlet-class>
    <load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
    <servlet-name>RestServlet</servlet-name>
    <url-pattern>*.rest</url-pattern>
</servlet-mapping>

Then I created another servlet context file RestServlet-servlet.xml, where I put <context:component-scan base-package="my.app.rest"/> - that's the package, where I then put a RestController, like this:

@RestController
public class RestService {

    public RestService() {
        System.out.println("yes!");
    }

    @RequestMapping(value = "/user.rest", method = RequestMethod.GET)
    public String getUser() {
        return "abc";
    }
}

The rest controller indeed is created (I debugged the constructor), so spring does see it, but when I try to call it from the Postman (Chrome extension), I get 404 response. My request is for URL: localhost:8080/acc/user.rest (where acc is my app name).

Why my calls matching *.rest do not get redirected to proper controller? (I tried to stop there in debug - it's never called).

EDIT 1:

This is my current full web.xml:

Note, that the last line in log comes from my GET request try to the rest service.

Answer 1

Found the problem. It turned out that both *-servlet.xml context files should have <mvc:annotation-driven /> declaration in order to have controllers working properly. Without it the servlet worked, but mappings were not handled correctly.

Answer 2

It seems to me the difference in the servlet name in servlet definition and mapping(<servlet-name>RestServlet</servlet-name> and <servlet-name>AccServlet</servlet-name>) is causing the problem.

You are naming the dispatcher servlet AccServlet and providing the mapping for RestServlet will not work.

In spring-mvc all delegation is done by DispatcherServlet.A possible combination would be:

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>/WEB-INF/core-context.xml /WEB-INF/spring-security.xml</param-value>
</context-param>

<listener>
    <listener-class>
        org.springframework.web.context.ContextLoaderListener
    </listener-class>
</listener>
<servlet>
    <servlet-name>AccServlet</servlet-name>
    <servlet-class>
        org.springframework.web.servlet.DispatcherServlet
    </servlet-class>
    <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
    <servlet-name>AccServlet</servlet-name>
    <url-pattern>/*</url-pattern>
</servlet-mapping>
<filter>
    <filter-name>springSecurityFilterChain</filter-name>
    <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
</filter>

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

<session-config>
    <session-timeout>10</session-timeout>
</session-config>

Then your RESt controller could be like this:

@RestController
@RequestMapping("/rest")
public class RestService {
}

All your rest clients would user URl of the pattern http://ip:port/yourapp/rest/something
The MVC controller could be:

@Controller
@RequestMapping("/mvc")
public class JspController {

  @RequestMapping(value = "/index.do", method = RequestMethod.GET)
  public String provideIndexModel(ModelMap model) {
      User user = userService.getLoggedUser();
      model.addAttribute("user", user.getUsername());
      if (user.getBusiness() != null) {
          model.addAttribute("business",   user.getBusiness().getCompanyName());
      }
      return "index";
  }
}

Use the URL of the pattern localhost:8080/acc/mvc/index.do for MVC stuff.
