The @Import<\/code> annotation allows you to specify which configurations your Spring application should load.<\/p>\n\n\n\n

You can think of this annotation as your Java class’s import statements. In this case, it\u2019s going to import only classes with the @Configuration<\/code> annotation. It\u2019s not the exact concept, but you get the idea.<\/p>\n\n\n\n

By using the @Import<\/code>, you explicitly import configurations. This annotation is useful when you need specific configurations from a package that is not scanned by default for your application, and you don\u2019t want to load all configurations in that package.<\/p>\n\n\n\n

You can also use it to group some configurations and load that specific group.<\/p>\n\n\n\n

Let\u2019s see an example:<\/h2>\n\n\n\n

Let’s create some configuration classes that we can import using @Import:<\/p>\n\n\n\n

<\/circle><\/circle><\/circle><\/g><\/svg><\/span><\/path><\/path><\/svg><\/span>
import<\/span> <\/span>org<\/span>.<\/span>springframework<\/span>.<\/span>context<\/span>.<\/span>annotation<\/span>.<\/span>Bean<\/span>;<\/span><\/span>\nimport<\/span> <\/span>org<\/span>.<\/span>springframework<\/span>.<\/span>context<\/span>.<\/span>annotation<\/span>.<\/span>Configuration<\/span>;<\/span><\/span>\n<\/span>\n@<\/span>Configuration<\/span><\/span>\npublic<\/span> <\/span>class<\/span> <\/span>DataSourceConfig<\/span> <\/span>{<\/span><\/span>\n<\/span>\n    <\/span>@<\/span>Bean<\/span><\/span>\n    <\/span>public<\/span> <\/span>DataSource<\/span> <\/span>dataSource<\/span>()<\/span> <\/span>{<\/span><\/span>\n        <\/span>return<\/span> <\/span>new<\/span> <\/span>DataSource<\/span>(<\/span>"<\/span>url<\/span>"<\/span>,<\/span> <\/span>"<\/span>username<\/span>"<\/span>,<\/span> <\/span>"<\/span>password<\/span>"<\/span>)<\/span>;<\/span><\/span>\n    <\/span>}<\/span><\/span>\n}<\/span><\/span>\n<\/span>\n@<\/span>Configuration<\/span><\/span>\npublic<\/span> <\/span>class<\/span> <\/span>ServiceConfig<\/span> <\/span>{<\/span><\/span>\n<\/span>\n    <\/span>@<\/span>Bean<\/span><\/span>\n    <\/span>public<\/span> <\/span>MyService<\/span> <\/span>myService<\/span>()<\/span> <\/span>{<\/span><\/span>\n        <\/span>return<\/span> <\/span>new<\/span> <\/span>MyService<\/span>()<\/span>;<\/span><\/span>\n    <\/span>}<\/span><\/span>\n}<\/span><\/span>\n<\/span>\n<\/span><\/code><\/pre><\/div>\n\n\n\n
However, importing all configurations can be exhausting. We can create groups (like categories), to group these configurations and use @Import to achieve this.<\/p>\n\n\n\n
<\/circle><\/circle><\/circle><\/g><\/svg><\/span><\/path><\/path><\/svg><\/span>
import<\/span> <\/span>org<\/span>.<\/span>springframework<\/span>.<\/span>context<\/span>.<\/span>annotation<\/span>.<\/span>Configuration<\/span>;<\/span><\/span>\nimport<\/span> <\/span>org<\/span>.<\/span>springframework<\/span>.<\/span>context<\/span>.<\/span>annotation<\/span>.<\/span>Import<\/span>;<\/span><\/span>\n<\/span>\n@<\/span>Configuration<\/span><\/span>\n@<\/span>Import<\/span>({<\/span>DataSourceConfig<\/span>.<\/span>class<\/span>,<\/span> <\/span>ServiceConfig<\/span>.<\/span>class<\/span>})<\/span><\/span>\npublic<\/span> <\/span>class<\/span> <\/span>AppConfig<\/span> <\/span>{<\/span><\/span>\n}<\/span><\/span>\n<\/span>\n<\/span><\/code><\/pre><\/div>\n\n\n\n
Then when we are configuring our application, we can import the configuration groups using the @Import annotation.<\/p>\n\n\n\n
<\/circle><\/circle><\/circle><\/g><\/svg><\/span><\/path><\/path><\/svg><\/span>
import<\/span> org.springframework.boot.SpringApplication;<\/span><\/span>\nimport<\/span> org.springframework.boot.autoconfigure.SpringBootApplication;<\/span><\/span>\nimport<\/span> org.springframework.context.annotation.Import;<\/span><\/span>\n<\/span>\n@<\/span>SpringBootApplication<\/span><\/span>\n@<\/span>Import<\/span>(AppConfig.class)<\/span><\/span>\npublic<\/span> <\/span>class<\/span> <\/span>MyApplication<\/span> {<\/span><\/span>\n    <\/span>public<\/span> <\/span>static<\/span> <\/span>void<\/span> <\/span>main<\/span>(<\/span>String<\/span>[] <\/span>args<\/span>) {<\/span><\/span>\n        SpringApplication.<\/span>run<\/span>(MyApplication.class, args);<\/span><\/span>\n    }<\/span><\/span>\n}<\/span><\/span>\n<\/span>\n<\/span><\/code><\/pre><\/div>\n\n\n\n
Now you know how to configure your Spring applications using the @Import annotation.<\/p>\n\n\n\n
