Question

我有一个课程，即下面提供的@Injectable() export class Globals { public baseURL:string; public loginURL:string; public proxyURL:string; public servicesURL:string; constructor(platformLocation: PlatformLocation) { this.baseURL = (platformLocation as any).location.href; this.loginURL = this.baseURL + 'rest/login'; this.proxyURL = this.baseURL + 'rest/proxy'; this.servicesURL = this.baseURL + 'rest/serviceRegistry'; } }，

OrderProviderData

我想设置public class OrderProviderData { public enum TradingInterface {CX_CLIENT, CX_SERVER, CX_ADMIN, CX_ENGINE} private boolean easyTrade = false; private OrderPreSelect order; private String[] event; public OrderPreSelect getOrder() { return order; } public void setOrder(OrderPreSelect order) { this.order = order; } public String[] getEvent() { return event; } public void setEvent(String[] event) { this.event = event; } }实例的值基于某些条件的OrderProviderData方法。

receiveEvent

如何正确编写？我也愿意提供更好的建议。

将枚举作为字段添加到您的班级。您只是定义枚举本身。（也需要吸气剂和固定剂）

公共类OrderProviderData {

public enum TradingInterface {CX_CLIENT, CX_SERVER, CX_ADMIN, CX_ENGINE}

private boolean easyTrade = false;

private TradingInterface tradingInterface;

private OrderPreSelect order;
private String[] event;

public OrderPreSelect getOrder() {
    return order;
}

public void setOrder(OrderPreSelect order) {
    this.order = order;
}

public String[] getEvent() {
    return event;
}

public void setEvent(String[] event) {
    this.event = event;
}

public TradingInterface getTradingInterface() {
    return tradingInterface;
}

public void setTradingInterface(TradingInterface tradingInterface) {
    this.tradingInterface = tradingInterface;
}

}

然后您可以switch查看案例（这是枚举的值）。您无法在switch和第一case

@Override
public final Object receiveEvent() throws Exception {
    Server f = new Server();

    switch (f.getInf()) {
    case CX_CLIENT:
        // set
        break; // optional

    case CX_SERVER:
        // set
        break; // optional

    default:
        // some code
    }

}

设置类的枚举值
