使用嵌入式Mongo DB进行Spring启动测试时启动速度非常慢

spring-boot-test startup spring-boot mongodb

    即使运行一个测试,您也需要超过1分钟的时间:

    • 嵌入式Mongo启动约1分钟

    我不明白这种行为的原因是什么?
    从控制台截取以下内容:

    full console log

    这句话在台词之后最难理解:

    c、 t.p.p.c.AsyncConfigurationTest:为测试创建同步任务执行器

    pom 文件: 

    <parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.1.0.RELEASE</version>
    <relativePath/> <!-- lookup parent from repository -->
</parent>
<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-mongodb</artifactId>
    </dependency>
    <dependency>
        <groupId>de.flapdoodle.embed</groupId>
        <artifactId>de.flapdoodle.embed.mongo</artifactId>
        <version>2.1.1</version>

    <dependency>

        <artifactId>spring-boot-starter-test</artifactId>
        <scope>test</scope>
    </dependency>

    没有额外的插件,只有 spring-boot-maven-plugin .
    此外,没有额外的配置 application.yml 用于测试。

    接下来是Mongo配置: 

    @Configuration
public class MongoConfig {

    private static final String MONGO_DB_URL = "localhost";
    private static final String MONGO_DB_NAME = "embeded_db";

    @Bean
    public MongoTemplate mongoTemplate() throws IOException {
        EmbeddedMongoFactoryBean mongo = new EmbeddedMongoFactoryBean();
        mongo.setBindIp(MONGO_DB_URL);
        MongoClient mongoClient = mongo.getObject();
        return new MongoTemplate(mongoClient, MONGO_DB_NAME);
    }
}

    任务执行器配置: 

    @Slf4j
@Configuration
@Profile("test")
public class AsyncConfigurationTest {

    @Bean
    @Primary
    public TaskExecutor taskExecutor() {
        log.info("Creating sync task executor for tests");
        return new SyncTaskExecutor();
    }
}

    下一步是测试: 

    @Slf4j
@SpringBootTest
@ActiveProfiles("test")
@RunWith(SpringRunner.class)
public class ServiceTest extends BaseDataServiceTest {

@Value("classpath:enter/enter_file.pdf")
private Resource enterPdf;
@Value("classpath:enter/expected.json")
private Resource enterExpectedJson;

@Test
public void testEnterDemoDocument() {
    testHelper(enterPdf, enterExpectedJson);
}


    如何调查it的瓶颈是什么?

    启动如此缓慢的原因是什么?

    弹簧靴具有开箱即用的支持 embedded MongoDB . 还有 embedmongo-spring 似乎已经过时了,因为已经三年没碰过了。

    对嵌入式MongoDB使用开箱即用的支持,而不是试图围绕它包装其他东西。

    您还可以删除 <version> 

    <dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-mongodb</artifactId>
</dependency>
<dependency>
    <groupId>de.flapdoodle.embed</groupId>
    <artifactId>de.flapdoodle.embed.mongo</artifactId>
    <scope>test</scope>
</dependency>
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-test</artifactId>
    <scope>test</scope>
</dependency>

    这些依赖项应该是您所需要的全部。

            InetAddress ret = InetAddress.getLocalHost();

    这就是解决办法 InetAddress.getLocalHost() slow to run (30+ seconds)
