When using MockMvc to test the controller, a parameter passing error occurred - spring

Question

I am using MockMvc to test the controller. Regarding parameter import, I encountered a type mismatch problem. I tried all the json styles.But nothing works
This is my controller class::
package app.dnatask.controller;
import ......;
#Slf4j
#RestController
#RequestMapping(value = "/API/scanresultconfigure")
public class ScanResultConfigureController extends BaseController {
#RequestMapping(value = "/queryScanResultList/{taskId}/{externalname}", method = RequestMethod.POST)
public IBaseResult queryscanResultList(final HttpServletRequest request, #PathVariable final String taskId, #PathVariable final String externalname, #RequestBody Map map) throws Exception {
return runController(new IControllRunner() {
public void run(IOutResult or, CheckResult cr) throws Exception {
......
}
}
}
}
This is my test class::
package app.dnatask.controller;
import ......
#WebAppConfiguration
#ContextConfiguration(classes = {ScanResultConfigureController.class})
#ComponentScan(
includeFilters = {
#ComponentScan.Filter(type = FilterType.CUSTOM,
value = {ScanResultConfigureController.class})
},
useDefaultFilters = false,
lazyInit = true
)
public class ScanResultConfigureControllerTest extends AbstractTestNGSpringContextTests {
#Autowired
private WebApplicationContext webApplicationContext;
private MockMvc mockMvc;
#BeforeMethod
public void setup() {
mockMvc = MockMvcBuilders.webAppContextSetup(webApplicationContext).dispatchOptions(true).build();
System.out.println("UT starting.............");
}
#AfterMethod
public void am() {
System.out.println("UT ending.............");
}
#Test
public void testQueryscanResultList() throws Exception {
Map<String, String> testMap = new HashMap<>();
testMap.put("key1", "value1");
testMap.put("key2", "value2");
String requestJson = JSONObject.toJSONString(testMap);
mockMvc.perform(
post("/API/scanresultconfigure/queryScanResultList/001/abc")
.contentType(MediaType.APPLICATION_JSON)
.param("map", requestJson)
)
.andExpect(status().isOk())
.andDo(print());
}
}
Error message::
org.springframework.web.HttpMediaTypeNotSupportedException: Content type 'application/json' not supported
java.lang.AssertionError: Status expected:<200> but was:<415>
This is a project implemented by springmvc framework, I use TestNG for unit testing.

Regarding my problem, the solution is as follows::
MvcResult mvcResult = mockMvc.perform(
post("/API/scanresultconfigure/queryScanResultList/{taskId}/{externalname}", "123", "abc")
.contentType(MediaType.APPLICATION_JSON)
.content(requestJson)
)
.andExpect(status().isOk())
.andDo(print())
.andReturn();
