json – Spring Boot HttpMediaTypeNotSupportedException

2019年8月5日 192次阅读

我目前正在绞尽脑汁为什么包含一个参数@RequestBody Car car打破了我的终点.

我是Spring的新手,并尝试将json字符串发布到我的休息控制器.

这是我的控制器：

@RestController
@RequestMapping("/v1/car")
@EnableWebMvc
public class CarController  {

private static final Log LOGGER = LogFactory.getLog(CarController.class);

@Autowired
private CarService carService;


@RequestMapping(value="/{accountId}", method = RequestMethod.POST, consumes={"text/plain", "application/*"})
ResponseEntity<?> start(@PathVariable final Integer accountId, @RequestBody Car car) {
    System.out.println("E: "+accountId);
    final long tid = Thread.currentThread().getId();
    final Boolean status = this.smarterWorkFlowService.startWorkFlow(accountId, car);
    return new ResponseEntity<Car>(new Car(), HttpStatus.ACCEPTED); 
}
}

我也使用jackson作为我的json解析器.我找了好几个小时,发现什么都没能帮我解释为什么我得到415回复.

{
    “timestamp”：1425341476013,
    “地位”：415,
    “错误”：“不支持的媒体类型”,
    “exception”：“org.springframework.web.HttpMediaTypeNotSupportedException”,
    “message”：“不支持的媒体类型”,
    “路径”：“/ v1 / experience / 12”
}

谢谢你的帮助！！

最佳答案 首先,在春季启动时不需要@EnableWebMvc.然后,如果您的REST服务需要生成json或xml使用

@RequestMapping(value = "properties", consumes = {MediaType.APPLICATION_JSON_VALUE, MediaType.APPLICATION_XML_VALUE}, method = RequestMethod.POST)

测试你的服务

HttpHeaders headers = new HttpHeaders();
headers.add("Content-type", header);
headers.add("Accept", header);

UIProperty uiProperty = new UIProperty();
uiProperty.setPassword("emelendez");
uiProperty.setUser("emelendez");

HttpEntity entity = new HttpEntity(uiProperty, headers);

RestTemplate restTemplate = new RestTemplate();
ResponseEntity<String> response = restTemplate.exchange("http://localhost:8080/properties/1", HttpMethod.POST, entity,String.class);
return response.getBody();

用application / json或application / xml替换头.如果您使用xml,请添加此依赖项

<dependency>
    <groupId>com.fasterxml.jackson.dataformat</groupId>
    <artifactId>jackson-dataformat-xml</artifactId>
</dependency>
