java - @ConditionalOnProperty on TYPE level w/@Configuration

Question

是否可以在 TYPE 级别使用 @ConditionalOnProperty，以便它查看/评估非默认属性文件中定义的属性？

以下似乎仅当属性在默认属性文件中定义时才有效，即在 application.properties

@Configuration
@ConditionalOnProperty(prefix = "jmx.rmi", value = "enabled")
public class JmxConfiguration {
    // JMX related stuff
}

Answer 1

@ConditionalOnProperty 从 org.springframework.core.env.Environment bean 中提取数据。这取决于您如何填充它。您可以显式声明多个属性文件:

@PropertySources({
        @PropertySource(name = "default", value = "classpath:application.properties"),
        @PropertySource(name = "custom", value = "file:custom.properties", ignoreResourceNotFound = true)
})
public class SpringBootApplication {...}

并且这两个文件的内容将附加到 Environment
