Spring JUnit 测试未加载完整的应用程序上下文

Question

Hi I am trying to so spring junit test cases... and I require my full application context to be loaded. However the junit test does not initialize the full application context.

Test class:

@RunWith(SpringJUnit4ClassRunner.class)
@SpringApplicationConfiguration(classes = Application.class)
public class MongoDbRepositoryTest {

    @Value("${spring.datasource.url}")
    private String databaseUrl;

    @Inject
    private ApplicationContext appContext;

    @Test
    public void testCRUD() {
        System.out.println("spring.datasource.url:" + databaseUrl);
        showBeansIntialised();
        assertEquals(1, 1);
    }

    private void showBeansIntialised() {
        System.out.println("BEEEAAANSSSS");
        for (String beanName : appContext.getBeanDefinitionNames()) {
            System.out.println(beanName);
        }
    }

Output:

spring.datasource.url:${spring.datasource.url}
BEEEAAANSSSS
org.springframework.context.annotation.internalConfigurationAnnotationProcessor
org.springframework.context.annotation.internalAutowiredAnnotationProcessor
org.springframework.context.annotation.internalRequiredAnnotationProcessor
org.springframework.context.annotation.internalCommonAnnotationProcessor
org.springframework.context.annotation.internalPersistenceAnnotationProcessor
org.springframework.context.annotation.ConfigurationClassPostProcessor.importAwareProcessor
org.springframework.context.annotation.ConfigurationClassPostProcessor.enhancedConfigurationProcessor

Main Application Class Annotations:

@ComponentScan(basePackages = "com.test")
@EnableAutoConfiguration(exclude = { MetricFilterAutoConfiguration.class, MetricRepositoryAutoConfiguration.class })
@EnableMongoRepositories("com.test.repository.mongodb")
@EnableJpaRepositories("com.test.repository.jpa")
@Profile(Constants.SPRING_PROFILE_DEVELOPMENT)
public class Application { ...

Hence it should scan all the spring bean in the package com.test and also load them into the applicationcontext for the Junit testcase. But from the output of the beans initalised it doesnt seem to be doing this.

Answer 1

You need to annotate your test class with @ActiveProfiles as follows; otherwise, your Application configuration class will always be disabled . That's why you currently do not see any of your own beans listed in the ApplicationContext .

@RunWith(SpringJUnit4ClassRunner.class)
@SpringApplicationConfiguration(classes = Application.class)
@ActiveProfiles(Constants.SPRING_PROFILE_DEVELOPMENT)
public class MongoDbRepositoryTest { /* ... */ }

In addition, Application should be annotated with @Configuration as was mentioned by someone else.

Answer 2

您是否可能在Application类中缺少@Configuration注释？

Answer 3

在每个无法扩展的测试类中添加 @ActiveProfile 在 VM 选项中添加它

-Dspring.profiles.active=test
