- html - 出于某种原因,IE8 对我的 Sass 文件中继承的 html5 CSS 不友好?

我决定编写一个相当简单的测试来检查我的Spring Boot自动配置是否正常工作-所有必需的bean及其依赖关系都已创建。
自动配置是:
package org.project.module.autoconfigure;
import org.project.module.SomeFactory;
import org.project.module.SomeProducer;
import org.project.module.SomeServiceClient;
import org.springframework.boot.autoconfigure.condition.ConditionalOnMissingBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
/**

* @author istepanov
*/
@Configuration
@ComponentScan("org.project.module.support")
public class SomeAutoConfiguration {
@Bean
@ConditionalOnMissingBean
public SomeFactory someFactory() {
return new SomeFactory();
}
@Bean
@ConditionalOnMissingBean
public SomeServiceClient someServiceClient() {
return new SomeServiceClient();
}
@Bean
@ConditionalOnMissingBean
public SomeProducer someProducer() {
return new SomeProducer();
}
}
package org.project.module.autoconfigure;
import org.project.module.SomeFactory;
import org.project.module.SomeProducer;
import org.project.module.SomeServiceClient;

@RunWith(SpringJUnit4ClassRunner.class)
@SpringBootTest(classes = {SomeAutoConfiguration.class}, webEnvironment = SpringBootTest.WebEnvironment.NONE)
public class SomeAutoConfigurationTest {

最佳答案
在我看来,这更像是一个常规的Spring配置问题,不一定是Spring Boot自动配置问题。
在测试中,您仅配置了SomeAutoConfiguration
来初始化应用程序上下文,并且由于有了@ComponentScan
批注,它会发现其他要设置的组件,例如SomeMetrics
。 SomeMetrics
依赖于某些Spring Boot Actuator bean的存在,由于测试中的上下文配置狭窄,它们不存在。
如果您想让事情正常工作,则必须在上下文中添加更多的bean,或者在SomeMetrics
组件中添加一些条件以防止它被创建,除非存在必要的bean,例如:
@Component
@ConditionalOnBean({CounterService.class, GaugeService.class})
public class SomeMetrics {
// Content ommitted for brevity.
}
