Spring MVC test - Injecting a mock repository when ever the integration test requires a specific type

Question

I have written a web application using spring mvc 3. It provides a single endpoint that returns JSON. I did having it running successfully using url paramters but now I need to change this to use path variables instead.

I changed my controller

from:

@Controller
public class DataController {

    @Autowired
    private IDataService dateService;

    @RequestMapping(
            value = "/some/data",
            method = RequestMethod.GET,
            produces = "application/json"
    )
    public @ResponseBody Data getDataByCode(@RequestParam String code) {
        return versionService.getDataByCode(code);
    }
}

to:

@Controller
public class DataController {

    @Autowired
    private IDataService dateService;

    @RequestMapping(
            value = "/some/data/{code}",
            method = RequestMethod.GET,
            produces = "application/json"
    )
    public @ResponseBody Data getDataByCode(@PathVariable String code) {
        return versionService.getDataByCode(code);
    }
}

and my web xml to map the url...

from:

    <servlet>
        <servlet-name>dataBycode</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:/config/servlet-config.xml</param-value>
        </init-param>
    </servlet>

    <servlet-mapping>
        <servlet-name>dataBycode</servlet-name>
        <url-pattern>/some/data</url-pattern>
    </servlet-mapping>

to:

    <servlet>
        <servlet-name>dataBycode</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:/config/servlet-config.xml</param-value>
        </init-param>
    </servlet>

    <servlet-mapping>
        <servlet-name>dataBycode</servlet-name>
        <url-pattern>/some/data/*</url-pattern>
    </servlet-mapping>

But I get a 404 for the http request: http://localhost/some/data/1234 Where I know that 1234 exists.

To top it off, the request never even gets to the controller method, so its got to be the web xml url pattern configuration.

As a test I tried changing the url pattern to exactly match a request with a code and it returned JSON as expected, so I know its the url pattern. I just dont know how to fix it.

I have tried:

1. /
2. /*
3. /some/data*
4. /some/data/*

Answer 1

Your url-pattern should be:

  <servlet-mapping>
        <servlet-name>dataBycode</servlet-name>
        <url-pattern>/</url-pattern>
  </servlet-mapping>

In the second hand, can you try to access http://localhost/some/data/myTest and put a System.out.println in your getDataByCode method to see if the method is called.

If it works I think the problem come from Spring MVC which interprate "1234" as an integer and not a String.

Answer 2

If your are using Eclipse:

1. Double click on your Server inside Server View

2. Go to Modules Tab

3. check the path for your Application

The final application url = path + some/data/1234
