java - 根据多个 Spring 配置文件定义 bean

Question

我的应用程序中有 3 个配置文件，名为:dev、test、prod。我想使用 spring 配置文件来自定义 bean 注入(inject)，这样对于配置文件开发和测试我将有一个 bean 实现，对于配置文件生产我将有另一个。问题是如何实现这一目标。我如何设置一个 bean 在两个不同的配置文件中处于 Activity 状态。我试过这样的事情:

@Component
@Profile("dev, test")
class DevTestBean{}

但不幸的是，spring 将其视为一个名为 dev comma space test 的配置文件。

Answer 1

你必须更改为 @Profile({"dev", "test"})

该值必须声明为 Set。查看documentation

If a @Configuration class is marked with @Profile, all of the @Bean methods and @Import annotations associated with that class will be bypassed unless one or more of the specified profiles are active. This is analogous to the behavior in Spring XML: if the profile attribute of the beans element is supplied e.g., , the beans element will not be parsed unless at least profile 'p1' or 'p2' has been activated. Likewise, if a @Component or @Configuration class is marked with @Profile({"p1", "p2"}), that class will not be registered or processed unless at least profile 'p1' or 'p2' has been activated.
