Spring测试-java.lang.IllegalArgumentException:没有足够的变量值可供扩展

我为UserController编写了下面的单元测试
@RunWith(SpringJUnit4ClassRunner.class)
@SpringApplicationConfiguration(classes = Application.class)
@WebAppConfiguration
public class UserControllerTest {
private final Log log = LogFactory.getLog(getClass());
private MediaType contentType = new MediaType(MediaType.APPLICATION_JSON.getType(),
MediaType.APPLICATION_JSON.getSubtype(),
Charset.forName("utf8"));

private HttpMessageConverter mappingJackson2HttpMessageConverter;
private final String USER_URL = "/{userId}/grantAuthz";
private final String USER_ID = "111";
private final String USER_NAME = "MockUser";
@Autowired
private WebApplicationContext webApplicationContext;
@Autowired
private UserRepository userRepository;
private String createdToken = null;
@Autowired
void setConverters(HttpMessageConverter<?>[] converters) {
this.mappingJackson2HttpMessageConverter = Arrays.asList(converters).stream().filter(
hmc -> hmc instanceof MappingJackson2HttpMessageConverter).findAny().get();
Assert.assertNotNull("the JSON message converter must not be null",
this.mappingJackson2HttpMessageConverter);
}
@Before
public void setup() throws Exception {
this.mockMvc = webAppContextSetup(webApplicationContext).build();
}
@Test
public void testGrantAuthorizationForUser() throws Exception{
Optional<UserEntity> userEntityAuthz = userRepository.findOneByUsername(USER_NAME);
Set<String> expectedAuthzList = (LinkedHashSet)userEntityAuthz.get().getAuthorizations();
List<String> grantList = new ArrayList<>();
grantList.add("ABC");
grantList.add("DEF");
grantList.add("GHI");
grantList.add("JKL");
grantList.add("MNO");
grantList.add("PQR");
grantList.add("STU");
grantList.add("VWX");
grantList.add("YZA");
JSONObject json = new JSONObject();
json.put("grantList",grantList);
MvcResult grantAuthzResult = mockMvc.perform(MockMvcRequestBuilders.post(USER_URL)
.contentType(contentType)
.param("userId",USER_ID)
.param("authorities",json.toString()))
.andExpect(status().isOk())
.andDo(print())

@以前
public void setup()引发异常{
this.mockMvc=webAppContextSetup(webApplicationContext.build();
}
@试验
public void testGrantAuthorizationForUser()引发异常{
可选userEntityAuthz=userRepository.findOneByUsername(用户名);
Set expectedAuthzList=(LinkedHashSet)userEntityAuthz.get().getAuthorizations();
List grantList=new ArrayList();
授权列表。添加(“ABC”);
授权列表。添加(“DEF”);
赠款清单。添加(“GHI”);
授权列表。添加(“JKL”);
授权列表。添加(“MNO”);
增列授权清单(“PQR”);
增列授权清单(“STU”);
授权列表添加(“VWX”);
增列(简称“YZA”);
JSONObject json=新的JSONObject();
put(“grantList”,grantList);
MvcResult grantAuthzResult=mockMvc.perform(MockMvcRequestBuilders.post(用户URL)
.contentType(contentType)
.param(“用户ID”,用户ID)
.param(“authorities”,json.toString()))
.andExpect(状态().isOk())
.andDo(print())
.andReturn();
}
}
执行时,我的测试会引发非法参数异常:
“没有足够的变量值可用于展开“userId”
我在测试中使用.param()方法发送所需的URL参数,我做错了什么?我提到了这个可能重复的问题,但没有发现它有多大用处 我发现我做错了什么,这里使用param()方法不是正确的方法,因为我的控制器方法中有
@PathVariable
和@RequestBody
作为参数
public Collection<UserEntity.UserAuthz> grantAuthz(@PathVariable("userId") String userId,
@RequestBody ArrayList<String> authorities) {
由于所需的类型是@RequestBody ArrayList
而不是使用JSONObject
,因此我使用JSONArray
并使用content()方法将JSONArray作为字符串发送
以下是我对测试方法所做的更改
@Test
public void testGrantAuthorizationForUser() throws Exception{
Optional<UserEntity> userEntityAuthz = userRepository.findOneByUsername(USER_NAME);
Set<String> expectedAuthzList = (LinkedHashSet)userEntityAuthz.get().getAuthorizations();
List<String> grantList = new ArrayList<>();
grantList.add("ABC");
grantList.add("DEF");
grantList.add("GHI");
grantList.add("JKL");
grantList.add("MNO");
grantList.add("PQR");
grantList.add("STU");
grantList.add("VWX");
grantList.add("YZA");
JSONArray json = new JSONArray();
MvcResult grantAuthzResult = mockMvc.perform(MockMvcRequestBuilders.post(USER_URL,USER_ID)
.contentType(contentType)
.content(json.toString()))
.andExpect(status().isOk())
.andDo(print())
.andReturn();
}
@测试
public void testGrantAuthorizationForUser()引发异常{
可选userEntityAuthz=userRepository.findOneByUsername(用户名);
Set expectedAuthzList=(LinkedHashSet)userEntityAuthz.get().getAuthorizations();
List grantList=new ArrayList();
授权列表。添加(“ABC”);
授权列表。添加(“DEF”);
赠款清单。添加(“GHI”);
授权列表。添加(“JKL”);
授权列表。添加(“MNO”);
增列授权清单(“PQR”);
增列授权清单(“STU”);
授权列表添加(“VWX”);
增列(简称“YZA”);
JSONArray json=新的JSONArray();
MvcResult grantAuthzResult=mockMvc.perform(MockMvcRequestBuilders.post(用户URL、用户ID)
.contentType(contentType)
.content(json.toString())
.andExpect(状态().isOk())
.andDo(print())
.andReturn();
}
这太棒了。帮助了我+从我这里得到1。谢谢
