如何将 Spring 配置文件设置为 package？

Question

I want to set a profile name to a whole package and I don't know how. If where is no easy way then I have to mark every class in the package and sub packages with @Profile annotation.

<context:component-scan/> tag does not support attribute like profile so I have no idea.

Answer 1

You can set profile for:

• Spring Beans XML file - for xml configuration

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd"
       profile="your-profile">

    <context:component-scan base-package="your.package" />
</beans>

• @Configuration class for Java config

@Configuration
@Profile("your-profile")
@Componentscan("your.package")
class AppConfig {
}

In each of them you can use component scanning for your a particular package.

Answer 2

If you don't mix XML and Java config you could use @Profile on a bean which has @ComponentScan annotation with your target package maybe?

Similarly with XML: you can have two different <beans ...> sections, each with different profile and in each of the section you define your own <context:component-scan basePackage="..." />

@Configuration
@Profile("profile1")
@ComponentScan(basePackage="package1")
class Config1 {
}

@Configuration
@Profile("profile2")
@ComponentScan(basePackage="package2")
class Config2 {
}
