问题描述
我想在一个配置类中有多个@PostConstruct注释方法，应根据@Profile进行调用.您可以想像这样的代码片段:
I'd like to have multiple @PostConstruct annotated methods in one configuration class, that should be called dependent on the @Profile. You can imagine a code snipped like this:
@Configuration
public class SilentaConfiguration {
private static final Logger LOG = LoggerFactory.getLogger(SilentaConfiguration.class);
@Autowired
private Environment env;
@PostConstruct @Profile("test")
public void logImportantInfomationForTest() {
LOG.info("********** logImportantInfomationForTest");
}
@PostConstruct @Profile("development")
public void logImportantInfomationForDevelopment() {
LOG.info("********** logImportantInfomationForDevelopment");
}
}
但是，根据@PostConstruct的javadoc，我只能使用一种使用此注释进行注释的方法. Spring的Jira中对此有一个开放的改进， https://jira.spring.io/browse/SPR -12433 .
However according to the javadoc of @PostConstruct I can only have one method annotated with this annotation. There is an open improvement for that in Spring's Jira https://jira.spring.io/browse/SPR-12433.
您如何解决此要求?我总是可以将此配置类分为多个类，但是也许您有一个更好的主意/解决方案.
How do you solved this requirement? I can always split this configuration class into multiple classes, but maybe you have a better idea/solution.
顺便说一句.上面的代码运行没有问题，但是无论配置文件设置如何，都可以调用这两种方法.
BTW. The code above runs without problems, however both methods are called regardless of the profile settings.
推荐答案
我用每个@PostConstruct方法的一个类解决了它. (这是Kotlin，但几乎翻译成了Java 1:1.)
I solved it with one class per @PostConstruct method. (This is Kotlin but it translates to Java almost 1:1.)
@SpringBootApplication
open class Backend {
@Configuration
@Profile("integration-test")
open class IntegrationTestPostConstruct {
@PostConstruct
fun postConstruct() {
// do stuff in integration tests
}
}
@Configuration
@Profile("test")
open class TestPostConstruct {
@PostConstruct
fun postConstruct() {
// do stuff in normal tests
}
}
}
