Spring，我没有用于测试的应用程序上下文。这有什么问题？

我是一天到春天

这是我的测试看起来的方式

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration
public class PropertyReaderTest {

    @Autowired
    private PropertyReader propertyReader;
    @Test
    public void testGetProfile() throws Exception {
        System.out.printf(System.getProperty("spring.active.profiles"));
        assertEquals("development", propertyReader.getProfile());
    }
}

这是我的源类

@Component
public class PropertyReader {
    @Value("${spring.active.profiles")
    private String profile;

    @Nonnull
    public String getProfile() {
        return profile;
    }

和maven依赖

<dependencies>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-context</artifactId>
            <version>4.0.3.RELEASE</version>
        </dependency>
    </dependencies>

我看了docs，他们的代码就像

一样 
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "/simple-job-launcher-context.xml", 
                                    "/jobs/skipSampleJob.xml" })
public class SkipSampleFunctionalTests extends AbstractJobTests { ... }

但是我没有任何这样的上下文文件，我缺少什么？

当你只是将ContextConfiguration留空时，就像这样.. 

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration // nothing defined here
public class PropertyReaderTest {

...然后它将查看上下文定义的默认位置。这通常以xml文件的形式出现，您可以在其中定义bean和“上下文”信息。

在该xml文件中，您将要创建一个正在尝试使用Spring @Autowire的PropertyReader的bean定义。你没想到Spring只是知道怎么做而没有一些指示吗？ ;）和Spring一样神奇，你需要帮助它定义一些东西。

也许您想要运行一个独立的JUnit测试文件，其中包含自己定义的所有内容。然后你可以这样定义你的类：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes=PropertyReaderTest.class)
public class PropertyReaderTest {

您告诉JUnit在您自己的类中查找Context定义，它将读取您在JUnit类中添加的任何注释定义。

请记住，当你希望Spring在“Context”中阅读时，需要以某种形式定义上下文......

如果您不想明确定义所有组件，可以让Spring查找它们。但是，你仍然需要创建一个告诉Spring这样做的上下文。看这里： http://docs.spring.io/spring/docs/3.0.0.M3/reference/html/ch04s12.html

答案 1 :(得分：0)

春天的

上下文文件是配置和注册bean所必需的。

如果我们不想使用它，那么我们应该以其他方式配置bean。

所以我们现在会看到你的问题的其他方法（基于java的bean配置）

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(loader=AnnotationConfigContextLoader.class)
public class PropertyReaderTest {

@Configuration
    static class ContextConfiguration {

        // this bean will be injected into the OrderServiceTest class
        @Bean
        public PropertyReader getPropertyReader () {
            PropertyReader propertyReader  = new PropertyReader();
            // set profile property and other properties, etc.
            return propertyReader;
        }
    }

    @Autowired
    private PropertyReader propertyReader;

    @Test
    public void testGetProfile() throws Exception {
        System.out.printf(System.getProperty("spring.active.profiles"));
        assertEquals("development", propertyReader.getProfile());
    }
}
