在每个春季启动 @Test 上覆盖单个 @Configuration 类 [英] Override a single @Configuration class on every spring boot @Test

问题描述

在我的 Spring Boot 应用程序中，我只想用测试配置覆盖我的 @Configuration 类之一(特别是我的 @EnableAuthorizationServer @Configuration class)，在我所有的测试中.

On my spring boot application I want to override just one of my @Configuration classes with a test configuration (in particular my @EnableAuthorizationServer @Configuration class), on all of my tests.

到目前为止spring boot 测试功能和spring 集成测试功能没有直接的解决方案浮出水面:

So far after an overview of spring boot testing features and spring integration testing features no straightforward solution has surfaced:

• @TestConfiguration:用于扩展，而不是覆盖；
• @ContextConfiguration(classes=… ) 和 @SpringApplicationConfiguration(classes =… ) 让我覆盖整个配置，而不仅仅是一个类；
• 建议使用 @Test 内部的 @Configuration 类来覆盖默认配置，但未提供示例；

• @TestConfiguration: It's for extending, not overriding;
• @ContextConfiguration(classes=…​) and @SpringApplicationConfiguration(classes =…​) let me override the whole config, not just the one class;
• An inner @Configuration class inside a @Test is suggested to override the default configuration, but no example is provided;

有什么建议吗?

推荐答案

内测配置

用于测试的内部 @Configuration 示例:

Example of an inner @Configuration for your test:

@RunWith(SpringRunner.class)
@SpringBootTest
public class SomeTest {

    @Configuration
    static class ContextConfiguration {
        @Bean
        @Primary //may omit this if this is the only SomeBean defined/visible
        public SomeBean someBean () {
            return new SomeBean();
        }
    }

    @Autowired
    private SomeBean someBean;

    @Test
    public void testMethod() {
        // test
    }
}

可重复使用的测试配置

如果您希望对多个测试重用测试配置，您可以使用 Spring Profile @Profile("test") 定义一个独立的配置类.然后，让您的测试类使用 @ActiveProfiles("test") 激活配置文件.查看完整代码:

If you wish to reuse the Test Configuration for multiple tests, you may define a standalone Configuration class with a Spring Profile @Profile("test"). Then, have your test class activate the profile with @ActiveProfiles("test"). See complete code:

@RunWith(SpringRunner.class)
@SpringBootTests
@ActiveProfiles("test")
public class SomeTest {

    @Autowired
    private SomeBean someBean;

    @Test
    public void testMethod() {
        // test
    }
}

@Configuration
@Profile("test")
public class TestConfiguration {
    @Bean
    @Primary //may omit this if this is the only SomeBean defined/visible
    public SomeBean someBean() {
        return new SomeBean();
    }
}

@Primary

bean定义上的@Primary注解是为了确保在发现多个时优先使用这个.

The @Primary annotation on the bean definition is to ensure that this one will have priority if more than one are found.
