Question

我尝试按照本教程

https://jaxenter.de/jax-rs-20-websocket-13453（德语教程）

现在我被卡住了。我已经完成了所有的事情，直到听力4.现在我想尝试一下，如果它能起作用的话。大多数代码只是与其他一些变量名称重复，但当我尝试在我的服务器上部署此程序时，它总是显示我：

引起：org.jboss.weld.exceptions.DeploymentException：WELD-001408：带有限定符@Default的MarketPriceStore类型的不满意依赖项在注入点[UnbackedAnnotatedField] @Inject private ws.SimpleStockMarketResource.marketPriceStore 在ws.SimpleStockMarketResource.marketPriceStore（SimpleStockMarketResource.java:0）

Class MarketPriceStore出了问题，我不知道是什么......

我的MarketPriceStore代码

@Singleton
@LocalBean

public class MarketPriceStore {
    private Map<String,Double> map = new HashMap<String,Double>();

@Inject
Event<MarketpriceChangedEventObject> eventSource;

public void store(String companyName, Double marktPreisNeu){
    Double marktPreisAlt = map.get(companyName);

    if(!Objects.equals(marktPreisAlt, marktPreisNeu)){
        map.put(companyName,marktPreisNeu);
        eventSource.fire(new MarketpriceChangedEventObject(companyName, marktPreisNeu));
    }
}

public Optional<Double> retrieve(String key){
    return Optional.ofNullable(map.get(key));
}

我已经问了一位同事，我们搜索了一下，但没有一个答案令人满意。

我的MarketpriceChangedEventObject代码

public class MarketpriceChangedEventObject {
public final String companyName;
public final Double marktpreis;
public MarketpriceChangedEventObject(String companyName, Double marktpreis){
    this.companyName = companyName;
    this.marktpreis = marktpreis;
    }
}

我的SimpleStockMarketResource代码

public class SimpleStockMarketResourceClient {

private static final String URI = "http://localhost:8080/Entenhausen/ws/SimpleStockMarketResource";

public static void main(String[] args) throws Exception {
    try {
        String operation = args[0];
        String companyName = args[1];

        if (operation.equalsIgnoreCase("-get")) {
            Double marketPrice = ClientBuilder.newClient()
                    .target(URI)
                    .path("{companyName}")
                    .resolveTemplate("companyName", companyName)
                    .request()
                    .get(Double.class);
            System.out.println("SUCCESS: Get! => [Market Price=" + marketPrice + "]");
        } else if (operation.equalsIgnoreCase("-set")) {
            Double marketPrice = Double.valueOf(args[2]);

            Response response = ClientBuilder.newClient()
                    .target(URI)
                    .path("{companyName}")
                    .resolveTemplate("companyName", companyName)
                    .request()
                    .put(Entity.text(marketPrice));

            if (response.getStatusInfo().getFamily() == Response.Status.Family.SUCCESSFUL) {
                System.out.println("SUCCESS: Set!");
            } else {
                System.err.println("ERROR: Set! => [Status Code=" + response.getStatus() + "]");
            }
        }
    } catch (Exception e) {
        e.printStackTrace();
    }
}

}

为什么我的服务器会抛出此错误
