找不到java.lang.NoClassDefFoundError类：javax/servlet/SessionCookieConfig

我在项目中有依赖项

 compile("org.springframework.boot:spring-boot-starter-data-jpa") {
    exclude group: "org.apache.tomcat", module: "tomcat-jdbc"
    exclude group: "org.hibernate", module: "hibernate-entitymanager"
}
compile("org.springframework.boot:spring-boot-starter-security")
compile("org.springframework.boot:spring-boot-starter-mail")
compile("org.springframework.boot:spring-boot-configuration-processor")
compile("org.eclipse.persistence:org.eclipse.persistence.jpa")
compile("org.eclipse.persistence:org.eclipse.persistence.jpa.modelgen.processor")
compile("com.google.api-client:google-api-client")
compile("com.google.oauth-client:google-oauth-client-jetty")
compile("com.google.apis:google-api-services-drive")

   // dependencies from the inherited module (compile(project("..."))
    api("com.fasterxml.jackson.core:jackson-databind")
    api("org.hibernate.validator:hibernate-validator")
    api("commons-validator:commons-validator")
    api("org.apache.commons:commons-lang3")
    implementation("com.google.guava:guava")

我想做集成测试，所以我添加了依赖项

testCompile("com.github.springtestdbunit:spring-test-dbunit:1.3.0")
testCompile("org.dbunit:dbunit:2.5.4")

我创建了基本配置类

/**
 * Spring configuration class for integration tests.
 */
@Configuration 
@EnableAutoConfiguration 
@ComponentScan
public class PopcornCoreTestApplication {}

和一个抽象类

/**
 * Base class to save on configuration.
 */
@RunWith(SpringRunner.class)
@SpringBootTest(classes = PopcornCoreTestApplication.class, webEnvironment = SpringBootTest.WebEnvironment.MOCK)
@TestExecutionListeners(
        {
                DependencyInjectionTestExecutionListener.class,
                DirtiesContextTestExecutionListener.class,
                TransactionalTestExecutionListener.class,
                TransactionDbUnitTestExecutionListener.class
        }
)
public abstract class DBUnitTestBase {

    @Autowired
    private UserRepository userRepository;

    /**
     * Clean out the db after every test.
     */
    @After
    public void cleanup() {
        this.userRepository.deleteAll();
    }
}

和一些示例测试来检查它是否有效

/**
 * Integration tests for UserPersistenceServiceImpl.
 */
public class UserPersistenceServiceImplIntegrationTests extends DBUnitTestBase {

    @Autowired
    private UserPersistenceService userPersistenceService;

    /**
     * Setup.
     */
   @Test
    public void setup() {
        Assert.assertThat(this.userRepository.count(), Matchers.is(0L));
    }
}

而且它不起作用。我要开始考试了

关于所有错误

我试图添加一个依赖项

javax.servlet-api

但这没有帮助，同样的错误仍然存在

---

如何处理这个问题？

SessionCookieConfig类出现在3.0版的servlet api中

要解决问题，只需将此依赖项添加到build.gradle文件中即可

testCompile("javax.servlet:javax.servlet-api:3.1.0")

---

对于所有mvn用户，请在pom.xml中添加以下依赖项

<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>javax.servlet-api</artifactId>
    <version>3.1.0</version>
    <scope>test</scope>
</dependency>

javax.servlet
javax.servlet-api
3.1.0
测试
