我正在尝试为使用
Spring MVC实现的REST API编写集成测试.
这是我的REST实现:
import org.myproject.api.input.ProjectInput; import org.myproject.dao.ProjectsDao; import org.myproject.model.Project; import org.myproject.model.Projects; import org.myproject.util.Exceptions; import org.slf4j.Logger; import org.slf4j.LoggerFactory; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.http.MediaType; import org.springframework.web.bind.annotation.*; @RestController @RequestMapping("/projects") public class ProjectsApi { @Autowired private ProjectsDao projectsDao; ... @RequestMapping(value = "/",method = RequestMethod.POST,produces = {"application/json"},consumes = {"application/json"}) public @ResponseBody Project addProject(@RequestBody ProjectInput projectInput) throws IOException { logger.info("Add project"); Project project = projectInput.createProject(); projectsDao.add(project); return project; } }
这是ProjectInput类:
@XmlRootElement public class ProjectInput { private String name; private String description; // Constructor to make JSON converter happy private ProjectInput() {} public ProjectInput(String name,String description) { this.name = name; this.description = description; } public String getName() { return name; } public String getDescription() { return description; } public void setName(String name) { this.name = name; } public void setDescription(String description) { this.description = description; } }
这是我的测试:
import com.fasterxml.jackson.databind.ObjectMapper; import org.junit.Before; import org.junit.Test; import org.junit.runner.RunWith; import org.openboard.api.input.ProjectInput; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.http.MediaType; import org.springframework.test.context.ContextConfiguration; import org.springframework.test.context.junit4.SpringJUnit4ClassRunner; import org.springframework.test.context.web.WebAppConfiguration; import org.springframework.test.web.servlet.MockMvc; import org.springframework.test.web.servlet.setup.MockMvcBuilders; import org.springframework.web.context.WebApplicationContext; import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.post; import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.content; import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.status; import static org.springframework.test.web.servlet.result.MockMvcResultHandlers.print; @RunWith(SpringJUnit4ClassRunner.class) @WebAppConfiguration @ContextConfiguration(locations={"classpath*:applicationContext.xml"}) public class TestProjectsApi { @Autowired private WebApplicationContext wac; private MockMvc mockMvc; @Before public void setup() { this.mockMvc = MockMvcBuilders.webAppContextSetup(this.wac).build(); } @Test public void testAddProject() throws Exception { ProjectInput input = new ProjectInput("name","description"); ObjectMapper mapper = new ObjectMapper(); String json = mapper.writeValueAsString(input); // json value is: {"name":"name","description":"description"} mockMvc.perform(post("/projects/") .contentType(MediaType.APPLICATION_JSON) .content(json.getBytes())) .andDo(print()) .andExpect(status().isOk()) .andExpect(content().contentType(MediaType.APPLICATION_JSON)); } }
不幸的是我收到以下错误:
org.myproject.api.TestProjectsApi > testAddProject Failed java.lang.AssertionError: Status expected:<200> but was:<415> at org.springframework.test.util.AssertionErrors.fail(AssertionErrors.java:60) at org.springframework.test.util.AssertionErrors.assertEquals(AssertionErrors.java:89) at org.springframework.test.web.servlet.result.StatusResultMatchers$10.match(StatusResultMatchers.java:653) at org.springframework.test.web.servlet.MockMvc$1.andExpect(MockMvc.java:152) at org.myproject.api.TestProjectsApi.testAddProject(TestProjectsApi.java:48)
我使用以下Gradle命令在终端中执行测试:
./gradlew --daemon test --info
UPD.我在请求中添加了print()以查看正在发送/接收的内容:
org.myproject.api.TestProjectsApi > testAddProject STANDARD_OUT MockHttpServletRequest: HTTP Method = POST Request URI = /projects/ Parameters = {} Headers = {Content-Type=[application/json]} Handler: Type = org.myproject.api.ProjectsApi Async: Async started = false Async result = null Resolved Exception: Type = org.springframework.web.HttpMediaTypeNotSupportedException ModelAndView: View name = null View = null Model = null FlashMap: MockHttpServletResponse: Status = 415 Error message = null Headers = {Accept=[application/octet-stream,*/*,text/plain;charset=ISO-8859-1,application/xml,text/xml,application/*+xml,application/x-www-form-urlencoded,multipart/form-data]} Content type = null Body = Forwarded URL = null Redirected URL = null Cookies = [] Gradle Test Executor 1 finished executing tests.
解决方法
我有类似的情况,我可以通过添加header-accept和content-type来解决它.
Headers = {Accept=[application/json;charset=UTF-8],Content-Type=[application/json;charset=UTF-8]}
在测试模块中:
MediaType MEDIA_TYPE_JSON_UTF8 = new MediaType("application","json",java.nio.charset.Charset.forName("UTF-8")); MockHttpServletRequestBuilder request = post("/myPostPath"); request.content(json); request.locale(Locale.JAPANESE); request.accept(MEDIA_TYPE_JSON_UTF8); request.contentType(MEDIA_TYPE_JSON_UTF8); mockMvc.perform(request) .andDo(print()) .andExpect(status().isOk());
首先我只放了request.accept(..).但是在添加request.contentType(..)后它终于奏效了.
