我可以否定（！）一系列弹簧型材吗？ [英] Can I negate (!) a collection of spring profiles?

问题描述

是否可以以一种不被一组配置文件使用的方式配置bean？目前我可以这样做（我相信）：

Is it possible to configure a bean in such a way that it wont be used by a group of profiles? Currently I can do this (I believe):

@Profile("!dev, !qa, !local")

是否有更简洁的符号来实现这一目标？我们假设我有很多个人资料。另外，如果我有一个Mock和一些服务（或其他）的具体实现，我可以只注释其中一个，并假设另一个将用于所有其他情况？换句话说，这是必要的：

Is there a neater notation to achieve this? Let's assume I have lots of profiles. Also, if I have a Mock and concrete implementation of some service (or whatever), Can I just annotate one of them, and assume the other will be used in all other cases? In other words, is this, for example, necessary:

@Profile("dev, prof1, prof2")
public class MockImp implements MyInterface {...}

@Profile("!dev, !prof1, !prof2") //assume for argument sake that there are many other profiles
public class RealImp implements MyInterface {...}

我可以只注释其中一个，并坚持一个<相反，code> @Primary 注释？

Could I just annotate one of them, and stick a @Primary annotation on the other instead?

本质上我想要这个：

@Profile("!(dev, prof1, prof2)")

提前致谢！

推荐答案

简短回答是：你做不到。

但由于 @Conditional 注释，存在整齐的解决方法。

Short answer is : You can't.
But there are neat workaround that exists thanks to the @Conditional annotation.

public abstract class ProfileCondition extends SpringBootCondition {
    @Override
    public ConditionOutcome getMatchOutcome(ConditionContext conditionContext, AnnotatedTypeMetadata annotatedTypeMetadata) {
        if (matchProfiles(conditionContext.getEnvironment())) {
            return ConditionOutcome.match("A local profile has been found.");
        }
        return ConditionOutcome.noMatch("No local profiles found.");
    }

    protected abstract boolean matchProfiles(final Environment environment);
}

public class DevProfileCondition extends ProfileCondition {
   private boolean matchProfiles(final Environment environment) {    
        return Arrays.stream(environment.getActiveProfiles()).anyMatch(prof -> {
            return prof.equals("dev") || prof.equals("prof1")) || prof.equals("prof2"));
        });
    }
}

public class ProdProfileCondition extends ProfileCondition {
   private boolean matchProfiles(final Environment environment) {    
        return Arrays.stream(environment.getActiveProfiles()).anyMatch(prof -> {
            return !prof.equals("dev") && !prof.equals("prof1")) && !prof.equals("prof2"));
        });
    }
}

使用

Use it

@Conditional(value = {DevProfileCondition.class})
public class MockImpl implements MyInterface {...}

@Conditional(value = {ProdProfileCondition.class})
public class RealImp implements MyInterface {...}

但是，这个方法需要Springboot。

However, this aproach requires Springboot.
