我想在新项目中使用 Spring Data JPA。我基本上遵循https://spring.io/guides/gs/accessing-data-jpa/中描述的设置.
当我启动应用程序或开始单个测试时,一切正常。
一旦我同时开始两个测试,Spring 就无法在第二个测试中加载 ApplicationContext,因为它失败了:
java.lang.IllegalStateException: Failed to load ApplicationContext
Caused by: org.springframework.jmx.export.UnableToRegisterMBeanException: Unable to register MBean [HikariDataSource (testdb)] with key 'dataSource'; nested exception is javax.management.InstanceAlreadyExistsException: com.zaxxer.hikari:name=dataSource,type=HikariDataSource
如何避免第二次尝试注册 HikariDataSource?
这是我的 build.gradle
dependencies {
compileOnly "org.projectlombok:lombok:1.16.12"
compile "org.springframework.boot:spring-boot-starter-web"
compile "org.springframework.boot:spring-boot-starter-data-jpa"
compile "com.h2database:h2"
compile "org.apache.commons:commons-lang3:3.6"
testCompile "org.junit.jupiter:junit-jupiter-api:5.0.0"
testCompile "org.junit.jupiter:junit-jupiter-params:5.0.0"
testRuntime "org.junit.platform:junit-platform-launcher:1.0.0"
testRuntime "org.junit.jupiter:junit-jupiter-engine:5.0.0"
testCompile "org.springframework.boot:spring-boot-starter-test"
}
和第一个测试类
@SpringJUnitConfig(Application.class)
class FirstRepositoryTest {
@Autowired
private FirstRepository firstRepository;
使用junit 4和@RunWith(SpringJUnit4ClassRunner.class)
解决了问题,所以肯定是junit 5和spring交互导致的。
最佳答案
您需要为所有测试加载一次 Spring Context,例如 post它使用@ContextConfiguration:
that problem was loading the Spring Context with each test class. The solution was restructuring the test classes by extending an AbstractContext base class which loaded a Spring Context for all tests to share, and all the Beans therein.
