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

Question

>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();
}
}

和一些示例测试以检查它是否有效

/**
* 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。我正在弹出测试开始

在粘贴上所有错误 https://pastebin.com/8kC4Mkm6

我试图添加依赖项

javax.servlet-api

但它没有帮助，同样的错误仍然存在。

如何处理这个问题？

Answer 1

对于所有 MVN 用户，请将以下依赖项添加到 POM 中.xml

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

Answer 2

SessionCookieConfig类出现在 3.0 版的 servlet-api 中。

要解决您的问题，只需将此依赖项添加到您的build.gradle文件中

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