如果你已经引入了MongoDB的依赖,但是不想连接MongoDB,可以使用MongoDB的内存数据库模拟一个MongoDB实例。具体步骤如下:
1.在pom.xml文件中添加以下依赖:
```xml
<dependency>
<groupId>de.flapdoodle.embed</groupId>
<artifactId>de.flapdoodle.embed.mongo</artifactId>
<version>2.2.0</version>
<scope>test</scope>
</dependency>
```
2.在测试类中使用EmbeddedMongoFactoryBean创建一个内存MongoDB实例:
```java
import com.mongodb.MongoClient;
import cz.jirutka.spring.embedmongo.EmbeddedMongoFactoryBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.mongodb.core.MongoTemplate;
@Configuration
public class MongoConfig {
private static final String MONGO_DB_URL = "localhost";
private static final String MONGO_DB_NAME = "test";
@Bean
public MongoTemplate mongoTemplate() throws Exception {
EmbeddedMongoFactoryBean mongo = new EmbeddedMongoFactoryBean();
mongo.setBindIp(MONGO_DB_URL);
MongoClient mongoClient = mongo.getObject();
MongoTemplate mongoTemplate = new MongoTemplate(mongoClient, MONGO_DB_NAME);
return mongoTemplate;
}
}
```
3.在测试类中使用@ContextConfiguration注解引入MongoConfig配置类,并使用@Autowired注解注入MongoTemplate实例即可。
