我有一个spring
rest网络应用程序，其中包含一个通用的rest控制器，如下所示。杰克逊将对象序列化为JSON后，GET方法运行良好。但是，当我尝试调用save方法时，RequestBody参数将转换为LinkedHashMap，而不是T泛型类型定义的类型。

@RestController
public abstract class CrudAPI<T extends Object, ID extends Serializable>{

    @Transactional
    @RequestMapping(method = RequestMethod.POST, consumes = "application/json")
    public ResponseEntity<Void> save(@RequestBody T entity){
        service.save(entity);
        return new ResponseEntity(HttpStatus.CREATED);
    }

}

JSON：

{
   "id":null,
   "version":null,
   "name":"Copel",
   "disabled":false,
   "type":"P",
   "labels":[
      {
         "id":null,
         "version":null,
         "name":"unidade consumidora"
      }
   ]
}

我收到以下错误：

HTTP状态500-请求处理失败；嵌套的异常是org.springframework.beans.NotReadablePropertyException：Bean类[java.util.LinkedHashMap]的无效属性“版本”：在回退访问期间找不到属性字段！

Spring配置：

@Configuration
@Import(Application.class)
@EnableWebMvc
@ComponentScan(basePackages = {"br.com.doc2cloud"})
public class WebConfig extends WebMvcConfigurerAdapter implements WebApplicationInitializer {

    @Override
    public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) {
        configurer.enable();
    }

    private MappingJackson2HttpMessageConverter jacksonConverter() {
        ObjectMapper mapper = new ObjectMapper();
        mapper.registerModule(new Hibernate5Module());
        mapper.configure(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS, false);
        mapper.setDateFormat(new ISO8601DateFormat());
        mapper.setVisibility(PropertyAccessor.ALL, Visibility.NONE);
        mapper.setVisibility(PropertyAccessor.FIELD, Visibility.ANY);
        mapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);

        MappingJackson2HttpMessageConverter jacksonConverter = new MappingJackson2HttpMessageConverter();
        jacksonConverter.setObjectMapper(mapper);

        return jacksonConverter;
    }

 @Override
    public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
        converters.add(jacksonConverter());
        super.configureMessageConverters(converters);
    }

    @Override
    public void onStartup(ServletContext servletContext) throws ServletException {
        servletContext.setInitParameter("javax.servlet.jsp.jstl.fmt.localizationContext", "messages");
        EnumSet<DispatcherType> dispatcherTypes = EnumSet.of(DispatcherType.REQUEST, DispatcherType.FORWARD);
        CharacterEncodingFilter characterEncodingFilter = new CharacterEncodingFilter();
        characterEncodingFilter.setEncoding("UTF-8");
        characterEncodingFilter.setForceEncoding(true);
        FilterRegistration.Dynamic characterEncoding = servletContext.addFilter("characterEncoding", characterEncodingFilter);
        characterEncoding.addMappingForUrlPatterns(dispatcherTypes, true, "/*");
    }
}

我的代码有什么问题？
