在执行JpaTest时无法找到@SpringBootConfiguration [英] Unable to find a @SpringBootConfiguration when doing a JpaTest

问题描述

我是框架的新手（刚刚通过了这个类），这是我第一次使用springboot。

I'm new to frameworks (just passed the class) and this is my first time using springboot.

我正在尝试运行简单的Junit测试看看我的CrudRepositories是否确实有效。

I'm trying to run a simple Junit test to see if my CrudRepositories are indeed working.

我一直得到的错误是：

无法找到@SpringBootConfiguration，您需要在测试中使用@ContextConfiguration或@SpringBootTest（classes = ...）
java.lang.IllegalStateException

Unable to find a @SpringBootConfiguration, you need to use @ContextConfiguration or @SpringBootTest(classes=...) with your test java.lang.IllegalStateException

没有弹簧启动配置本身？

doesn't spring boot configure itself?

我的测试类

@RunWith(SpringRunner.class)
@DataJpaTest
@SpringBootTest(webEnvironment = WebEnvironment.RANDOM_PORT)
public class JpaTest {

@Autowired
private AccountRepository repository;

@After
public void clearDb(){
    repository.deleteAll();
}

 @Test
 public void createAccount(){
     long id = 12;
     Account u = new Account(id,"Tim Viz");
     repository.save(u);

     assertEquals(repository.findOne(id),u);

 }


 @Test
 public void findAccountByUsername(){
     long id = 12;
     String username = "Tim Viz";
     Account u = new Account(id,username);
     repository.save(u);

     assertEquals(repository.findByUsername(username),u);

 }

我的Spring启动应用程序启动器

My Spring boot application starter

@SpringBootApplication
@EnableJpaRepositories(basePackages = {"domain.repositories"})
@ComponentScan(basePackages = {"controllers","domain"})
@EnableWebMvc
@PropertySources(value    {@PropertySource("classpath:application.properties")})
    @EntityScan(basePackages={"domain"})
    public class Application extends SpringBootServletInitializer {
        public static void main(String[] args) {
            ApplicationContext ctx = SpringApplication.run(Application.class, args);         

        }
    }

我的存储库

public interface AccountRepository extends CrudRepository<Account,Long> {

    public Account findByUsername(String username);

    }
}

提前感谢

推荐答案

事实上，Spring Boot确实在很大程度上自我设定。你可能已经摆脱了很多你发布的代码，特别是在应用程序。

Indeed, Spring Boot does set itself up for the most part. You can probably already get rid of a lot of the code you posted, especially in Application.

我希望你已包含所有类的包名，或至少包含应用程序和 JpaTest 的包名。关于 @DataJpaTest 和其他一些注释的事情是他们在当前包中寻找 @SpringBootConfiguration 注释，如果他们在那里找不到它们，他们会遍历包层次结构直到找到它。

I wish you had included the package names of all your classes, or at least the ones for Application and JpaTest. The thing about @DataJpaTest and a few other annotations is that they look for a @SpringBootConfiguration annotation in the current package, and if they cannot find it there, they traverse the package hierarchy until they find it.

例如，如果测试类的完全限定名称是 com.example.test.JpaTest ，你的应用程序的那个是 com.example.Application ，那么你的测试类就可以了找到 @SpringBootApplication （其中， @SpringBootConfiguration ）。

For example, if the fully qualified name for your test class was com.example.test.JpaTest and the one for your application was com.example.Application, then your test class would be able to find the @SpringBootApplication (and therein, the @SpringBootConfiguration).

但是，如果应用程序位于包层次结构的不同分支中，例如 com.example.application.Application ，它将不找到它。

If the application resided in a different branch of the package hierarchy, however, like com.example.application.Application, it would not find it.

考虑以下Maven项目：

Consider the following Maven project:

my-test-project
  +--pom.xml
  +--src
    +--main
      +--com
        +--example
          +--Application.java
    +--test
      +--com
        +--example
          +--test
            +--JpaTest.java

然后 Application.java中的以下内容：

package com.example;

@SpringBootApplication
public class Application {

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

后跟的内容JpaTest.java ：

package com.example.test;

@RunWith(SpringRunner.class)
@DataJpaTest
public class JpaTest {

    @Test
    public void testDummy() {
    }
}

一切都应该有效。如果你在 src / main / com / example 中创建一个名为 app 的新文件夹，然后把你的<$ c其中有$ c> Application.java （并在文件中更新 package 声明），运行测试会出现以下错误：

Everything should be working. If you create a new folder inside src/main/com/example called app, and then put your Application.java inside it (and update the package declaration inside the file), running the test will give you the following error:

java.lang.IllegalStateException：无法找到@SpringBootConfiguration，您需要使用@ContextConfiguration或@SpringBootTest（classes = ...）与您的测试

java.lang.IllegalStateException: Unable to find a @SpringBootConfiguration, you need to use @ContextConfiguration or @SpringBootTest(classes=...) with your test
