Spring-boot-SpringBootCondition

下面的代码示例演示了如果当前服务的启动环境是windows系统，则不会注入Tyc这个类的实例到spring容器，如果不是windows系统，则会注入Tyc这个类的实例到spring容器

@Service
@Conditional(value = WindowsPlatformCondition.class)
public class Tyc{
    
}

/**
 * 如果是windows平台，则不会往spring中注入某些类的实例对象

@Component
public class WindowsPlatformCondition extends SpringBootCondition {

    private static final boolean IS_WINDOWS = System.getProperties().getProperty("os.name").toLowerCase(Locale.ROOT).contains("windows");

    @Override
    public ConditionOutcome getMatchOutcome(ConditionContext context, AnnotatedTypeMetadata metadata) {
        if (IS_WINDOWS) {
            return new ConditionOutcome(false, "windows platform");
        } else {
            return new ConditionOutcome(true, "windows platform");
        }
