java - Spring @ContextConfiguration

Question

我正在运行下一个测试:

import static org.junit.Assert.assertEquals;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "/META-INF/spring/applicationContext.xml" })
public class FloorServiceTest {

    @Autowired
    private FloorService floorService;

    @Test
    public void testFloorService() {

        floorService.findById((long)1);

    }
}

在文件夹/APP/src/main/resources/META-INF/spring/下有文件applicationContext.xml

但似乎没有正确地 Autowiring bean:

  org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'com.confloorapp.services.FloorServiceTest': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.confloorapp.services.FloorService com.confloorapp.services.FloorServiceTest.floorService; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [com.confloorapp.services.FloorService] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}

Answer 1

尝试

@ContextConfiguration(locations = { "classpath:/META-INF/spring/applicationContext.xml" })

老实说，我会离开 xml 而走这条路。改变

@ContextConfiguration(locations = { "/META-INF/spring/applicationContext.xml" })

到

@ContextConfiguration(classes = { FloorServiceTestConfig.class })

并创建关于类

@Configuration
public class FloorServiceTestConfig
{
    @Bean
    public FloorService floorService()
    {
          return new FloorService();
    }
}

这样当你需要为你的类模拟你的bean时你没有测试它看起来像下面

@Configuration
public class FloorServiceTestConfig
{
    @Bean
    public FloorService floorService()
    {
          return Mockito.mock(FloorService.class);
    }
}
