沒有找到 java.lang.NoClassDefFoundError 類：javax/servlet/SessionCookieConfig

Question

我在項目中有依賴項

 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")

我想做集成測試所以我添加了依賴項

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

我創建了基本的配置類

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

和一個抽象類

/**
 * 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();
    }
}

和一些示例測試來檢查它是否有效

/**
 * 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));
    }
}

它不工作。 我正在測試開始彈出

java.lang.NoClassDefFoundError: javax/servlet/SessionCookieConfig

在 pastebin 所有錯誤https://pastebin.com/8kC4Mkm6

我試圖添加一個依賴項

javax.servlet-api

但它沒有幫助，同樣的錯誤仍然存​​在。

如何處理？

Answer 1

SessionCookieConfig類出現在 3.0 版的 servlet-api 中。

要解決您的問題，只需將此依賴項添加到您的build.gradle文件中

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

Answer 2

對於所有 mvn 用戶，請將以下依賴項添加到 pom.xml

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