如何在使用@ConditionalOnProperty或@ConditionalOnExpression时检查两个条件 [英] How to check two condition while using @ConditionalOnProperty or @ConditionalOnExpression

问题描述

在创建bean时，我需要检查YAML属性文件上是否满足两个条件.我该怎么做，因为@ConditionalOnProperty批注仅支持一个属性?

I need to check that two conditions are satisfied on a YAML property file, while creating a bean. How do I do that, as the @ConditionalOnProperty annotation supports only one property?

推荐答案

从@ConditionalOnProperty开始，就可以检查多个属性.名称/值属性是一个数组.

Since from the beginning of @ConditionalOnProperty it was possible to check more than one property. The name / value attribute is an array.

@Configuration
@ConditionalOnProperty({ "property1", "property2" })
protected static class MultiplePropertiesRequiredConfiguration {

    @Bean
    public String foo() {
        return "foo";
    }

}

对于带有AND检查的简单布尔属性，不需要@ConditionalOnExpression.

For simple boolean properties with an AND check you don't need a @ConditionalOnExpression.
