有沒有相當於@Startup的彈簧？

Question

我必須將企業應用程序轉換爲spring。到目前爲止，我已經掌握了一切。但是我仍然需要在我的兩個bean上替換@Startup註釋。

是否有春季等價物，或者春天你會怎麼做？

在此先感謝！

Answer 1

不知道這是你要求的。我總是用@PostConstruct註釋在我的春節，豆，做的東西，需要在應用程序的啓動做：

@Component 
public class SchedulerBootstrap { 

    @Autowired 
    MyRepository myRepository; 

    @Autowired 
    OpenPropertyPlaceholderConfigurer configurer; 

    @PostConstruct 
    /** 
    * This method will be called after the bean has been 
    * instantiated and all dependencies injected. 
    */ 
    public void init() { 

    } 
} 

加入你如何編寫單元測試的例子與行爲實驗在Spring環境中的bean。

import org.springframework.beans.factory.annotation.Autowired; 
import org.springframework.test.context.ContextConfiguration; 
import org.springframework.test.context.junit4.AbstractJUnit4SpringContextTests; 

@ContextConfiguration(locations = {"classpath:spring-context.xml"}) 
public class BootstrapTest extends AbstractJUnit4SpringContextTests { 

    @Autowired 
    SchedulerBootstrap schedulerBootstrap; 

    @Test 
    public void myTest() { 
     //Some code that berifies that init-method had been called. 
     //Or start unit test in debug-mode and add a breakpoint in the 
     //init-method, you will see it being called before the test is executed. 
    } 
}
