我正在创建一个将接受 JSON 请求的 REST API。
我正在使用 CURL 对其进行测试：
curl -i -POST -H 'Accept: application/json' -d '{"id":1,"pan":11111}' http://localhost:8080/PurchaseAPIServer/api/purchase
但得到以下错误：
HTTP/1.1 415 Unsupported Media Type
Server: Apache-Coyote/1.1
Content-Type: text/html;charset=utf-8
Content-Length: 1051
Date: Wed, 25 Apr 2012 21:36:14 GMT
The server refused this request because the request entity is in a format not supported by the requested resource for the requested method ().
在调试时，它甚至不会进入我在控制器中的创建操作。
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.http.HttpStatus;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.bind.annotation.ResponseStatus;
import com.app.model.Purchase;
import com.app.service.IPurchaseService;
@Controller
public class PurchaseController {
@Autowired
private IPurchaseService purchaseService;
@RequestMapping(value = "purchase", method = RequestMethod.GET)
@ResponseBody
public final List<Purchase> getAll() {
return purchaseService.getAll();
}
@RequestMapping(value = "purchase", method = RequestMethod.POST)
@ResponseStatus( HttpStatus.CREATED )
public void create(@RequestBody final Purchase entity) {
purchaseService.addPurchase(entity);
}
}
更新
我将 Jackson 配置添加到 AppConfig.java：
@Configuration
@ComponentScan(basePackages = "com.app")
public class AppConfig {
@Bean
public AnnotationMethodHandlerAdapter annotationMethodHandlerAdapter()
{
final AnnotationMethodHandlerAdapter annotationMethodHandlerAdapter = new AnnotationMethodHandlerAdapter();
final MappingJacksonHttpMessageConverter mappingJacksonHttpMessageConverter = new MappingJacksonHttpMessageConverter();
HttpMessageConverter<?>[] httpMessageConverter = { mappingJacksonHttpMessageConverter };
String[] supportedHttpMethods = { "POST", "GET", "HEAD" };
annotationMethodHandlerAdapter.setMessageConverters(httpMessageConverter);
annotationMethodHandlerAdapter.setSupportedMethods(supportedHttpMethods);
return annotationMethodHandlerAdapter;
}
}
我的 GET 现在工作正常：
curl -i -H "Content-Type:application/json" -H "Accept:application/json" http://localhost:8080/PurchaseAPIServer/api/purchase
HTTP/1.1 200 OK
Server: Apache-Coyote/1.1
Content-Type: application/json
Transfer-Encoding: chunked
Date: Thu, 26 Apr 2012 21:19:55 GMT
[{"id":1,"pan":111}]
但是我在尝试 POST 时得到以下信息：
curl -i -X POST -H "Content-Type:application/json" -H "Accept:application/json" http://localhost:8080/PurchaseAPIServer/api/purchaseMe -d "{"id":2,"pan":122}"
HTTP/1.1 400 Bad Request
Server: Apache-Coyote/1.1
Content-Type: text/html;charset=utf-8
Content-Length: 971
Date: Thu, 26 Apr 2012 21:29:56 GMT
Connection: close
The request sent by the client was syntactically incorrect ().
我的模型：
@Entity
@XmlRootElement
public class Purchase implements Serializable {
/**
*
*/
private static final long serialVersionUID = 6603477834338392140L;
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Long id;
private Long pan;
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public Long getPan() {
return pan;
}
public void setPan(Long pan) {
this.pan = pan;
}
}
有什么想法我哪里出错了吗？
谢谢
