我從REST技術開始，選擇Spring 3.2和Jackson 2.2。我有一個小問題。我創建了REST API，它看起來像這樣：Spring 3.2 Jackson 2.2 REST API
@Controller
public class WorkersController {
@Autowired
public DatabaseService dbService;
@ResponseBody
@RequestMapping(value="/workers", method = RequestMethod.GET, produces = "application/json")
public ArrayList<Worker> getAllWorkersFromDatabase() {
}
@ResponseBody
@RequestMapping(value="/workers/new", method = RequestMethod.POST, produces = "application/json", consumes="application/json")
public String saveWorker(@RequestBody final WorkerDTO workerDto) {
}
@ResponseBody
@RequestMapping(value="/workers/{workerid}", method = RequestMethod.GET, produces = "application/json")
public Worker getWOrkerByDatabaseId(@PathVariable Integer workerid) {
}
@ResponseBody
@RequestMapping(value="/workers/{workerid}/edit", method = RequestMethod.PUT, produces = "application/json")
public String editWorker(@PathVariable Integer workerid, @RequestBody Worker worker) {
}
}
當我使HTTP GET一切正常但我有POST的問題。當我打電話saveWorker（）方法獲得：
The server refused this request because the request entity is in a format not supported by the requested resource for the requested method
我進口需要的庫：
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-core</artifactId>
<version>${jackson.version}</version>
</dependency>
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-databind</artifactId>
<version>${jackson.version}</version>
</dependency>
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-annotations</artifactId>
<version>${jackson.version}</version>
</dependency>
我認爲主要的問題是在配置文件和@RequestBody着地圖JSON到DTO。這是我的配置：
@Configuration
@ComponentScan(basePackages = "org.schedule.service")
@EnableWebMvc
@Import(DatabaseSpringConfig.class)
public class ServiceSpringConfig extends WebMvcConfigurationSupport{
@Override
protected void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
MappingJackson2HttpMessageConverter jsonConverter = new MappingJackson2HttpMessageConverter();
List<MediaType> jsonTypes = new ArrayList<>(jsonConverter.getSupportedMediaTypes());
jsonTypes.add(MediaType.TEXT_PLAIN);
jsonTypes.add(MediaType.APPLICATION_JSON);
jsonConverter.setSupportedMediaTypes(jsonTypes);
converters.add(jsonConverter);
}
}
我的DTO：
public class WorkerDTO implements Serializable {
private static final long serialVersionUID = 1L;
public String name;
public String surname;
public WorkerDTO() {
}
}
JSON：
{
"name": "asdssss",
"surname": "asdssssss"
}
和HTTP調用：
localhost:8080/Schedule-service/workers/new?Content-type=application/json
感謝您的回覆。
