Spring 在集成测试期间引导未解析来自 application.properties 的自定义属性

Spring boot not resolving custom properties from application.properties during integration tests

我的Spring开机测试配置如下:

@RunWith(SpringJUnit4ClassRunner.class)
@SpringApplicationConfiguration(classes = {TestEnd2EndIntegrationConfiguration.class})
@WebAppConfiguration
@ActiveProfiles(Profiles.TEST)//=="test"
@Transactional
public abstract class AbstractEnd2EndIntegrationTest {

}

然后从 application-test.properties 我有以下 custom 属性:

database.hibernate.dialect=org.hibernate.dialect.H2Dialect
database.hibernate.hbm2ddl.auto=create
database.hibernate.logSqlInfo=true

我使用如下:

@Value("${database.hibernate.dialect}")
private String hibernateDialect;

但是,自定义属性没有得到解决,我得到了如下异常:

com.bignibou.it.controller.signup.SignupRestControllerTest > shouldRejectUnavailableEmailAddress FAILED
    java.lang.IllegalStateException
        Caused by: org.springframework.beans.factory.BeanCreationException
            Caused by: org.hibernate.boot.registry.selector.spi.StrategySelectionException

编辑:

这是我的 gradle 配置:

 sourceSets {

        main {
            output.resourcesDir = output.classesDir
        }

        integrationTest {
            java.srcDirs = ['src/it/java']
            resources.srcDirs = ['src/it/resources', 'src/main/resources']
            compileClasspath = sourceSets.main.output + configurations.testRuntime
            runtimeClasspath = output + compileClasspath
        }
    }

   task integrationTest(type: Test) {
        description "Run the integration tests."
        testClassesDir = sourceSets.integrationTest.output.classesDir
        classpath = sourceSets.integrationTest.runtimeClasspath
        reports.html.destination = file("$reports.html.destination/integration")
        reports.junitXml.destination = file("$reports.junitXml.destination/integration")
    }

当我 运行 来自 IDE (intellij) 的测试时,我得到一个不同的错误:

这是来自 Gradle 集成测试

可以看出属性没有展开...这是为什么呢?

您需要 3 件事才能让您的属性在集成测试中自动装配 classes:

  1. PropertySource 注释。看起来你错过了那个。 您可以将类似的内容添加到您的抽象集成测试 class:
@PropertySource(value= {"classpath:*.properties"})
  1. 属性 文件必须在您的 class 路径中。我建议为测试和集成测试属性添加一个单独的文件夹。在 src/main 中创建一个 integration-test-resources 目录并将您的 属性 文件复制到那里,然后配置您的构建管理器以将它们添加为 class 路径资源。

下面是如何在 Gradle 中执行此操作的示例:

sourceSets {
  integrationTest {
     resources {
       srcDir "integration-test-resources"
     }
  }
}
  1. @Value 注释你的 属性。看起来你已经在这样做了。

如果您想将 Hibernate 属性放入 application-${profile}.properties,即 Spring 属性文件,我认为您应该使用 spring.jpa.hibernate.dll-auto

同样,应该使用spring.jpa.database-platform=org.hibernate.dialect.H2Dialect

我使用 Spring 这样的配置启动,我从来不需要任何 @PropertySource 注释。

问题实际上出在以下代码行:

@SpringApplicationConfiguration(classes = {TestEnd2EndIntegrationConfiguration.class})

TestEnd2EndIntegrationConfiguration 不是 Spring 带有主程序的引导应用程序,最重要的是它没有使用 @EnableAutoConfiguration 注释进行注释。

我改为:

@Configuration
@EnableAutoConfiguration(exclude = {
        ManagementWebSecurityAutoConfiguration.class,
        ...
        MailSenderAutoConfiguration.class
})
@ComponentScan(basePackages = {"com.bignibou.configuration", "com.bignibou.it.configuration"})
public class TestApplication {

    public static void main(String[] args) throws Exception {
        SpringApplication.run(TestApplication.class, args);
    }
}

和我的抽象测试class:

@RunWith(SpringJUnit4ClassRunner.class)
@SpringApplicationConfiguration(classes = {TestApplication.class})//Notice the change
@WebAppConfiguration
@ActiveProfiles(Profiles.TEST)
@Transactional
public abstract class AbstractIntegrationTest {

}

现在 运行 作为 spring 启动应用程序的测试和 application.properties 中的自定义属性也已解决。
