Java Question

Spring MockMvc redirectedUrl with pattern

I have a simple

PersonController
class that provides
save()
method to persist the object from http post request.

package org.rw.controller;

import java.sql.Timestamp;
import java.util.List;

import org.rw.entity.Person;
import org.rw.service.PersonService;
import org.rw.spring.propertyeditor.TimestampPropertyEditor;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.WebDataBinder;
import org.springframework.web.bind.annotation.InitBinder;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;


@Controller
@RequestMapping(value="/person")
public class PersonController {

private static final Logger logger = LoggerFactory.getLogger(PersonController.class);

@Autowired
private PersonService personService;

@Autowired
TimestampPropertyEditor timestampPropertyEditor;


@InitBinder
public void initBinder(WebDataBinder binder) {
binder.registerCustomEditor(Timestamp.class, "dob", timestampPropertyEditor);
}


@RequestMapping(value="/save", method=RequestMethod.POST)
public String save(Model model, Person person) {
Long personId = personService.save(person);
return "redirect:view/" + personId;
}

}


As the
save()
method returns as
return "redirect:view/" + personId;
. It will be diffrerent for every request. it may be like
"view/5"
or
"view/6"
depending on the id of the object that has been persisted.

Then i have a simple class to test the above controller with spring mocking.

package org.rw.controller;

import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.get;
import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.post;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.redirectedUrl;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.status;

import org.junit.Test;
import org.rw.service.UserService;
import org.rw.test.SpringControllerTest;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.authentication.UsernamePasswordAuthenticationToken;
import org.springframework.security.core.Authentication;
import org.springframework.security.core.context.SecurityContextHolder;
import org.springframework.security.core.userdetails.UserDetails;

public class PersonControllerTest extends SpringControllerTest {


@Autowired
private UserService userService;


@Test
public void add() throws Exception {
mockMvc.perform(get("/person/add", new Object[0])).andExpect(status().isOk());
}


@Test
public void save() throws Exception {
UserDetails userDetails = userService.findByUsername("anil");
Authentication authToken = new UsernamePasswordAuthenticationToken (userDetails.getUsername(), userDetails.getPassword(), userDetails.getAuthorities());
SecurityContextHolder.getContext().setAuthentication(authToken);

mockMvc.perform(
post("/person/save", new Object[0])
.param("firstName", "JunitFN")
.param("lastName", "JunitLN")
.param("gender", "M")
.param("dob", "11/02/1989")
).andExpect(
redirectedUrl("view")
);
}


}


now here i have a problem that
redirectedUrl("view")
is rejecting value
"view/5"
. I have tried
redirectedUrl("view*")
and
redirectedUrl("view/*")
but its not working.




Edit :

Here I have got a workaround as per below

MvcResult result = mockMvc.perform(
post("/person/save", new Object[0])
.param("firstName", "JunitFN")
.param("lastName", "JunitLN")
.param("gender", "MALE")
.param("dob", "11/02/1989")
).andExpect(
//redirectedUrl("view")
status().isMovedTemporarily()
).andReturn();

MockHttpServletResponse response = result.getResponse();

String location = response.getHeader("Location");

Pattern pattern = Pattern.compile("\\Aview/[0-9]+\\z");
assertTrue(pattern.matcher(location).find());


but still i am looking for the proper way.




update:

I have posted the same issue on spring jira here :

Answer

As of spring 3.x this is not supported out of the box but you can easily add you custom result matcher

private static ResultMatcher redirectedUrlPattern(final String expectedUrlPattern) {
    return new ResultMatcher() {
        public void match(MvcResult result) {
            Pattern pattern = Pattern.compile("\\A" + expectedUrlPattern + "\\z");
            assertTrue(pattern.matcher(result.getResponse().getRedirectedUrl()).find());
        }
    };
}

And use it like build-in matcher

 mockMvc.perform(
    post("/person/save", new Object[0])
        .param("firstName", "JunitFN")
        .param("lastName", "JunitLN")
        .param("gender", "M")
        .param("dob", "11/02/1989")
 ).andExpect(
        redirectedUrlPattern("view/[0-9]+")
 );
