java – Spring MVC测试框架 – 不支持的媒体类型
作者:互联网
我正在使用spring test mvc框架为控制器编写测试.我正在尝试测试一个post请求,它会产生JSON.实际代码正在运行但测试失败.
我得到错误状态预期200但得到415这意味着不支持的媒体类型.我检查网上的所有例子,似乎我的实现是正确的.请帮帮我.
MyTestcase TestStringPost()运行成功,但TestJSONPost失败.
我使用的是Spring 3.2
我的控制器
@Controller
public class HomeController {
@RequestMapping(value = "/v1/checkstringvalue", method = RequestMethod.POST, produces = "application/json")
public @ResponseBody void testStringPost(@RequestBody String value) {
logger.info("Welcome home! The client locale is {}.");
}
@RequestMapping(value = "/v1/checkjsonvalue", method = RequestMethod.POST, produces = "application/json")
public @ResponseBody String testJSONPost(@RequestBody Map<String, String> userMap) {
System.out.println("Inside test jsonpost controller");
logger.info("Welcome home! The client locale is {}.");
return "Success";
}
}
这是我的测试控制器
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration
@WebAppConfiguration
public class HomeControllerTest {
@Autowired
private WebApplicationContext wac;
private MockMvc mockMvc;
private static final String PROVIDER_A = "PROVIDER_A";
public static final MediaType APPLICATION_JSON_UTF8 = new MediaType(
MediaType.APPLICATION_JSON.getType(),
MediaType.APPLICATION_JSON.getSubtype(), Charset.forName("utf8"));
@Configuration
public static class TestConfiguration {
@Bean
public HomeController simpleController() {
return new HomeController();
}
}
@Before
public void setup() {
mockMvc = MockMvcBuilders.webAppContextSetup(wac).build();
}
@Test
public void testStringPost() throws Exception {
final String createJson = "hello";
ResultActions resultActions = mockMvc.perform(post(
"/v1/checkstringvalue").contentType(MediaType.TEXT_PLAIN)
.content(createJson));
resultActions.andDo(print());
resultActions.andExpect(status().isOk());
}
@Test
public void testjsonPost() throws Exception {
System.out.println("Inside testjsonpost");
final String createJson = "{\"name\":\"hello\",\"email\":\"hello@example.com\"}";
ObjectMapper objectMapper = new ObjectMapper();
ObjectNode userJson = objectMapper.createObjectNode();
userJson.put("name", "tarun");
userJson.put("email", "tarun@gmail.com");
ResultActions resultActions = mockMvc
.perform(post("/v1/checkjsonvalue")
.contentType(APPLICATION_JSON_UTF8)
.accept(APPLICATION_JSON_UTF8)
.content(objectMapper.writeValueAsBytes(userJson)));
resultActions.andDo(print());
resultActions.andExpect(status().isOk());
}
}
解决方法:
好的,所以有了
perform(post("/myapi").contentType(MediaType.APPLICATION_JSON).content("{\"mykey\":\"myvalue\"}"))
很重要
但也请检查您的控制器:如果缺少任何这些注释,它将无法工作:
@EnableWebMvc
@Controller
public class MyController {
@RequestMapping(value="/myapi", method=RequestMethod.POST)
public void postOnApi(@RequestBody MyWidget myWidget) {
}
}
@EnableWebMvc @Controller和@RequestBody都需要(在我的实验中)来删除415状态代码错误.
