我想编写必须使用 Spring Framework 和自定义 JPA 提供程序的集成测试。我认为简单的答案是创建一个测试类并对其进行注释,如下所示:
@RunWith(SpringRunner.class)
@SpringBootTest
public class Test { ...
希望所有需要的默认自动配置都能自行发生。但事实并非如此,错误是:
java.lang.IllegalStateException: Unable to find a @SpringBootConfiguration, you need to use @ContextConfiguration or @SpringBootTest(classes=...) with your test
我可以避免创建:
@SpringBootApplication
public class TestApp { ...
并且仅使用 src/test/java 文件夹并提供带有“@SpringBootTest(classes=...)”的配置?那我需要什么样的配置类呢?
最佳答案
我刚刚遇到问题,让我回到开头; 首先添加一个配置类ApplicationContainer
public final class ApplicationContainer {
private static volatile ApplicationContainer singleton;
private ApplicationContext context;
private ApplicationContainer()
{
}
public static ApplicationContainer getInstance()
{
if(ApplicationContainer.singleton == null)
{
synchronized(ApplicationContainer.class)
{
if(ApplicationContainer.singleton == null)
{
ApplicationContainer.singleton = new ApplicationContainer();
}
}
}
return ApplicationContainer.singleton;
}
public void setApplicationContext(ApplicationContext context)
{
this.context = context;
}
public <T> T getBean(Class<T> requiredType)
{
if(this.context == null)
{
throw new IllegalStateException("ApplicationContainer is not started");
}
return this.context.getBean(requiredType);
}
public void start()
{
if(this.context == null)
{
this.context = new AnnotationConfigApplicationContext(ApplicationConfig.class);
}
}
public void stop()
{
if(this.context == null)
{
return;
}
if(this.context instanceof AnnotationConfigApplicationContext)
{
((AnnotationConfigApplicationContext)this.context).close();
}
this.context = null;
}
@Configuration
@ComponentScan("com.domain.package")
public static class ApplicationConfig
{
}}
并像这样更改您的测试类:
@RunWith(SpringRunner.class)
@SpringBootTest(classes = {ApplicationContainer.ApplicationConfig.class})
public class YourTestIT {
@Autowired
private ApplicationContext applicationContext;
@Before
public void up() {
ApplicationContainer.getInstance().setApplicationContext(this.applicationContext);
}
@After
public void down() {
ApplicationContainer.getInstance().stop();
}
//test cases
}
然后你可以@Autowired你的存储库类并直接使用你也应该添加IT扩展你的测试类名称。
