问题描述
我有一个测试任务-apache CXF中的小型REST api,应该从远程资源获取股票汇率。我将其作为Maven项目(.war)运行并通过TomEE进行部署。我是这个主题的新手,这就是为什么我无法弄清楚,为什么我总是会收到404错误。
这就是我的服务
@Path("stock")
public class StockService {
private Stock stock = new Stock();
@GET
@Path("currencies")
@Produces("text/json")
public String getAllCurrencies() {
return stock.getAllCurrenciesJson();
}
@GET
@Path("{currency}/{date}")
@Produces("text/plain")
public String getRateByDate(@PathParam("currency") String currency,@PathParam("date") String date) {
return stock.findrateByDate(Currency.findByShortcut(currency),date);
}
@GET
@Path("{date}")
@Produces("text/json")
public String getAllRates(@PathParam("date") String date) {
return stock.findAllRatesByDate(date);
}
@GET
@Path("convert/{currency}/{date}")
@Produces("text/plain")
public String getConversionByDate(@PathParam("currency") String currency,@PathParam("date") String date,Double amount) {
return stock.convert(Currency.findByShortcut(currency),amount,date);
}
}
我隐藏了模型,因为问题肯定出在部署上。然后,我有几个预先创建的类,例如:
@ApplicationPath("service")
public class MyApplication extends Application {
@Override
public Set<Class<?>> getClasses() {
final Set<Class<?>> classes = new HashSet<>();
//I add this line
classes.add(StockService.class);
return classes;
}
}
@Singleton
@Startup
public class MyStartupBean {
private static final Logger logger = LoggerFactory.getLogger(MyStartupBean.class);
private final ServiceRegistryService serviceRegistryService;
protected MyStartupBean() {
this.serviceRegistryService = null;
}
@Inject
public MyStartupBean(ServiceRegistryService serviceRegistryService) {
this.serviceRegistryService = serviceRegistryService;
}
@postconstruct
public void init() {
logger.info("Starting service");
serviceRegistryService.registerService();
logger.info("Started service");
}
}
@ApplicationScoped
public class ServiceRegistryService {
private static final Logger logger = LoggerFactory.getLogger(ServiceRegistryService.class);
public void registerService() {
serviceRegistration = ServiceRegistry
.createRegistration("this.service.id:v1","/service/")
.build();
ServiceRegistry.submitRegistration(serviceRegistration);
logger.info("Service registered as {}",serviceRegistration);
}
}
我的web.xml
是空的(没有指定servlet
或类似的标签)以及beans.xml
。为了在服务器上运行我的服务(TomEE上的.war网络应用会自动部署),我应该对那些类进行更改或更改或添加?
P.S。而且我不允许使用Spring
解决方法
回答我的问题:问题是 TomEE 不支持 Java 11 的某些功能。我不得不将我的代码降级到 Java 8,然后它才能工作。
