我在Apache Servicemix上安装了Jersey RESTful服务。该服务无法正常工作的一种方法,错误日志是这样的:multipart/mixed MessageBodyWriter找不到(Jersey,Servicemix)
2015-09-10 12:12:25,374 | ERROR | tp1599275925-203 | WriterInterceptorExecutor | ? ? | 250 - org.glassfish.jersey.core.jersey-common - 2.17.0 | MessageBodyWriter not found for media type=multipart/mixed, type=class org.glassfish.jersey.media.multipart.FormDataMultiPart, genericType=class org.glassfish.jersey.media.multipart.MultiPart.
方法是这样的:
@Authenticated
@Path("/floor")
@POST
@Consumes("application/json")
@Produces("multipart/mixed")
public MultiPart getFloorHeatMap(@NotNull(message = "You must provide a floor.") @Valid Floor floor) {
try {
Map<File, String> resp = null;
if (floor == null) {
throw new Exception("you must provide a floor");
}
ValidatorFactory factory = Validation.byDefaultProvider()
.providerResolver(new OSGiServiceDiscoverer())
.configure()
.buildValidatorFactory();
Validator validator = factory.getValidator();
Set<ConstraintViolation<Floor>> constraints = validator.validate(floor, Default.class);
for (ConstraintViolation<Floor> cv : constraints) {
throw new Exception(cv.getMessage());
}
resp = template.requestBody(AppServerRouteBuilder.GET_HEATMAPS_ENDPOINT, floor, Map.class);
final MultiPart multipart = new FormDataMultiPart();
if (resp != null) {
for (File file : resp.keySet()) {
multipart.bodyPart(new FileDataBodyPart(file.getName(), file, new MediaType("image", resp.get(file))));
}
return multipart;
} else {
ServiceResponse response = new ServiceResponse(ResultCode.NOT_FOUND);
return new FormDataMultiPart().field("Response", "Failed to get HeatMaps", MediaType.TEXT_PLAIN_TYPE);
}
} catch (Exception e) {
LOG.error("EXCEPTION CAUGHT");
LOG.error(e.getMessage(), e);
ServiceResponse response = new ServiceResponse(ResultCode.INTERNAL_ERROR, e.getMessage());
return new FormDataMultiPart().field("Response", "Failed to get HeatMaps", MediaType.TEXT_PLAIN_TYPE);
}
}
我开始我的应用程序是这样的:
ServletContextHandler context = new ServletContextHandler(ServletContextHandler.SESSIONS);
context.setContextPath("/");
server = new Server(Integer.parseInt(getPort()));
server.setHandler(context);
ServletHolder sh = new ServletHolder(new ServletContainer());
Map<String, String>map = new HashMap<>();
map.put("jersey.config.server.provider.classnames",
"org.glassfish.jersey.jackson.JacksonFeature,org.glassfish.jersey.media.multipart.MultiPartFeature");
map.put("jersey.config.server.provider.packages", "com.extremenetworks.rfplanner.wb.resources");
map.put("jersey.config.server.jsonFeature", "JacksonFeature");
map.put("org.glassfish.jersey.media.multipart.MultiPartFeature", "MultiPartFeature");
map.put("jersey.config.beanValidation.enableOutputValidationErrorEntity.server", "true");
sh.setInitParameters(map);
context.addServlet(sh, getPathSpec());
server.start();
我在我的.pom文件中有所有必需的依赖关系,我也已经将Service Jersey的泽西OSGI包部署到了Servicemix。
请您指出错误可能来自哪里,因为我已阅读所有文档和论坛,但仍不知道该怎么办。
谢谢!
'ServletContainer'需要'ResourceConfig'作为参数。您可以在'ResourceConfig'中进行类型安全的配置,而不是依赖于字符串。这样你就可以知道你是否拥有所有必需的依赖关系。现在我们不知道。 Spring属性没有编译错误,而且你实际上并没有向我们显示你的依赖关系。 –
我会仔细检查一下,在pom.xml中有'org.glassfish.jersey.media:jersey-media-multipart'依赖项。另外,我在扩展'ResourceConfig'的Application类中使用'register(MultiPartFeature.class)'调用,但我猜你注册MultipartFeature的方法也应该起作用。 – jFrenetic
