Embedded Redis for Spring Boot
提问by Gurinder
I run my Integration Test cases with Spring Boot with the help of my local Redis server on my machine.
我在我机器上的本地 Redis 服务器的帮助下使用 Spring Boot 运行我的集成测试用例。
But I want an embedded Redis server which is not dependent on any server and can run on any environment, like the H2 in-memory database. How can I do it?
但是我想要一个不依赖于任何服务器并且可以在任何环境中运行的嵌入式 Redis 服务器，例如 H2 内存数据库。我该怎么做？
@RunWith(SpringJUnit4ClassRunner.class)
@WebAppConfiguration
@IntegrationTest("server.port:0")
@SpringApplicationConfiguration(classes = Application.class)
@DirtiesContext(classMode = DirtiesContext.ClassMode.AFTER_CLASS)
public class MasterIntegrationTest {
}

You can use an embedded Redis like https://github.com/kstyrc/embedded-redis
您可以使用嵌入式 Redis，如https://github.com/kstyrc/embedded-redis
- Add the dependency to your pom.xml
Adjust the properties for your integration test to point to your embedded redis, for example :
spring: redis: host: localhost port: 6379Instanciate the embedded redis server in a component that is defined in your tests only :
@Component public class EmbededRedis { @Value("${spring.redis.port}") private int redisPort; private RedisServer redisServer; @PostConstruct public void startRedis() throws IOException { redisServer = new RedisServer(redisPort); redisServer.start(); } @PreDestroy public void stopRedis() { redisServer.stop(); } }
- 将依赖项添加到您的 pom.xml
调整集成测试的属性以指向嵌入式 redis，例如：
spring: redis: host: localhost port: 6379在仅在测试中定义的组件中实例化嵌入式 redis 服务器：
@Component public class EmbededRedis { @Value("${spring.redis.port}") private int redisPort; private RedisServer redisServer; @PostConstruct public void startRedis() throws IOException { redisServer = new RedisServer(redisPort); redisServer.start(); } @PreDestroy public void stopRedis() { redisServer.stop(); } }

You can use ozimov/embedded-redisas a Maven(-test)-dependency (this is the successor of kstyrc/embedded-redis).
您可以使用ozimov/embedded-redis作为 Maven(-test) 依赖项（这是kstyrc/embedded-redis的继承者）。
Add the dependency to your pom.xml
<dependencies> ... <dependency> <groupId>it.ozimov</groupId> <artifactId>embedded-redis</artifactId> <version>0.7.1</version> <scope>test</scope> </dependency>Adjust your application properties for your integration test
spring.redis.host=localhost spring.redis.port=6379Use the embedded redis server in a test configuration
@TestConfiguration public static class EmbededRedisTestConfiguration { private final redis.embedded.RedisServer redisServer; public EmbededRedisTestConfiguration(@Value("${spring.redis.port}") final int redisPort) throws IOException { this.redisServer = new redis.embedded.RedisServer(redisPort); } @PostConstruct public void startRedis() { this.redisServer.start(); } @PreDestroy public void stopRedis() { this.redisServer.stop(); } }
将依赖项添加到您的 pom.xml
<dependencies> ... <dependency> <groupId>it.ozimov</groupId> <artifactId>embedded-redis</artifactId> <version>0.7.1</version> <scope>test</scope> </dependency>为集成测试调整应用程序属性
spring.redis.host=localhost spring.redis.port=6379在测试配置中使用嵌入式 redis 服务器
@TestConfiguration public static class EmbededRedisTestConfiguration { private final redis.embedded.RedisServer redisServer; public EmbededRedisTestConfiguration(@Value("${spring.redis.port}") final int redisPort) throws IOException { this.redisServer = new redis.embedded.RedisServer(redisPort); } @PostConstruct public void startRedis() { this.redisServer.start(); } @PreDestroy public void stopRedis() { this.redisServer.stop(); } }

you can see this repository: https://github.com/caryyu/spring-embedded-redis-server, fully integrated with Spring and Spring Boot
你可以看到这个仓库：https: //github.com/caryyu/spring-embedded-redis-server，与 Spring 和 Spring Boot 完全集成
maven dependency
Maven 依赖
<dependency>
<groupId>com.github.caryyu</groupId>
<artifactId>spring-embedded-redis-server</artifactId>
<version>1.1</version>
</dependency>
spring boot annotation
弹簧靴注解
@Bean
public RedisServerConfiguration redisServerConfiguration() {
return new RedisServerConfiguration();
}
usage of application.yml
application.yml 的使用
spring:
redis:
port: 6379
embedded: true

Another neat way is to use the testcontainerslibrary which can run any type of application that can in a Docker container and Redis is no exception. What I like best is that it is lightly coupled with the Spring Test ecosystem.
另一个巧妙的方法是使用testcontainers可以在 Docker 容器中运行任何类型的应用程序的库，Redis 也不例外。我最喜欢的是它与 Spring Test 生态系统的结合。
maven's dependency:
maven 的依赖：
<dependency>
<groupId>org.testcontainers</groupId>
<artifactId>testcontainers</artifactId>
<version>${testcontainers.version}</version>
</dependency>
simple integration test:
简单的集成测试：
@RunWith(SpringRunner.class)
@SpringBootTest(webEnvironment = WebEnvironment.RANDOM_PORT, properties = {"management.port=0"})
@ContextConfiguration(initializers = AbstractIntegrationTest.Initializer.class)
@DirtiesContext
public abstract class AbstractIntegrationTest {
private static int REDIS_PORT = 6379;
@ClassRule
public static GenericContainer redis = new GenericContainer("redis:3.0.6").withExposedPorts(REDIS_PORT);
public static class Initializer implements ApplicationContextInitializer<ConfigurableApplicationContext> {
@Override
public void initialize(ConfigurableApplicationContext ctx) {
// Spring Boot 1.5.x
TestPropertySourceUtils.addInlinedPropertiesToEnvironment(ctx,
"spring.redis.host=" + redis.getContainerIpAddress(),
"spring.redis.port=" + redis.getMappedPort(REDIS_PORT));
// Spring Boot 2.x.
TestPropertyValues.of(
"spring.redis.host:" + redis.getContainerIpAddress(),
"spring.redis.port:" + redis.getMappedPort(REDIS_PORT))
.applyTo(ctx);
}
}
}
