Question

假设我有一个如下所示的枚举：

    public enum Env {

    holding, integration, staging, production;

    public enum Holding {
        THE_SAME_ENUM("Some String1, "Another String1");

        String name;
        String uuid;

        Holding(String name, String uuid) { this.name = name; this.uuid = uuid; }

        public String getName() {return name;}

        public String getData() {return uuid;}
    }

    public enum Integration {

        THE_SAME_ENUM("Some String2, "Another String2");

        String name;
        String uuid;

        Integration(String name, String uuid) { this.name = name; this.uuid = uuid; }

        public String getName() {return name;}

        public String getData() {return uuid;}
    }

    public enum Staging {
        THE_SAME_ENUM("Some String3, "Another String3");

        String name;
        String uuid;

        Staging(String name, String uuid) { this.name = name; this.uuid = uuid; }

        public String getName() {return name;}

        public String getData() {return uuid;}
    }

    public enum Production {
        THE_SAME_ENUM("Some String4, "Another String4");

        String name;
        String uuid;

        Production(String name, String uuid) { this.name = name; this.uuid = uuid; }

        public String getName() {return name;}

        public String getData() {return uuid;}
    }
}

然后在一个方法中，我想做这样的事情：

Env env;
switch(System.getEnv()) {
    case holding:
        env = Env.holding;
    case integration:
        env = Env.integration;
    case staging:
        env = Env.staging;
    case production:
        env = Env.production;

    //Expecting "Some String(1)or(2)or(3)or(4)"
    System.out.println(env.THE_SAME_ENUM.getName());
}

我真的只想根据环境变量更改类型，然后根据环境使用我硬编码的设置。我还没有找到实现这个目标的方法。任何帮助将不胜感激！

您可能想要一些与此相关的内容

public enum Env {

    holding("Some String1", "Another String1"),
    integration("Some String2", "Another String2"), 
    staging("Some String3", "Another String3"), 
    production("Some String4", "Another String4");

    String name;
    String uuid;
    Env(String name, String uuid) { this.name = name; this.uuid = uuid; }

        public String getName() {return name;}

        public String getData() {return uuid;}
    }
}

这就是我最终解决问题的方法。枚举的每个参数代表不同的环境，我只使用getter方法为每个环境返回正确的id。

public enum EnvironmentIds {

USER_MANAGER_CHANGED("e29e902c","28a6e01c", "281916f6"),
USER_ADDED_TO_GROUP("5059020b", "f039fc37", "0e480029"),
USER_CREATED("d9bc6a0c", "f26f0a23", "9261f53a"),
USER_REMOVED_FROM_GROUP("fc30b97c", "15528295", "c08af3b2");


String holdingId;
String productionId;
String stagingId;

EnvironmentIds(String holdingId, String stagingId, String productionId) {
    this.holdingId = holdingId;
    this.stagingId = stagingId;
    this.productionId = productionId;
}

public String getId(String environment) {
    switch(environment) {
        case "holding":
            return getHoldingId();
        case "production":
            return getProductionId();
        case "staging":
            return getStagingId();
        default:
            return null;
    }
}
public String getHoldingId() {return holdingId;}

public String getProductionId() {return productionId;}

public String getStagingId() {return stagingId;}
}

我可以构造枚举枚举并使用方法根据变量切换内部枚举
