spring data mongo - 没有定义名为'mongoTemplate'的bean

我有一个spring数据mongo存储库类

public interface MyRepository extends MongoRepository<FeedbackDTO, String> {
}

在测试配置中，我使用EnableMongoRepositories注释

@EnableMongoRepositories(basePackages={"com.mypackage.repository.mongodb"})
public class ServiceTestConfiguration {

当我尝试测试使用此存储库的服务类时，它会抛出异常

引起：org.springframework.beans.factory.NoSuchBeanDefinitionException：在org.springframework.beans.factory.support.DefaultListableBeanFactory.getBeanDefinition（DefaultListableBeanFactory.java:698）〜[spring-beans-4.2}中没有定义名为'mongoTemplate'的bean .4.RELEASE.jar：4.2.4.RELEASE] at org.springframework.beans.factory.support.AbstractBeanFactory.getMergedLocalBeanDefinition（AbstractBeanFactory.java:1175)~ [spring-beans-4.2.4.RELEASE.jar：4.2 . 4.RELEASE] org.springframework上的org.springframework.beans.factory.support.AbstractBeanFactory.doGetBean（AbstractBeanFactory.java:284）〜[spring-beans-4.2.4.RELEASE.jar：4.2.4.RELEASE] . org.springframework.beans.factory.support.BeanDefinitionValueResolver.resolveReference中的beans.factory.support.AbstractBeanFactory.getBean（AbstractBeanFactory.java:197）〜[spring-beans-4.2.4.RELEASE.jar：4.2.4.RELEASE] （BeanDefinitionValueResolver.java:351）〜[spring-beans-4.2.4.RELEASE.jar：4.2.4.RELEASE] ...省略了57个常用帧

    @EnableMongoRepositories 注释将在启动时触发存储库bean的创建，但您仍需要注册MongoDB连接并创建注入这些存储库的 MongoTemplate 实例 . 见Spring Data MongoDB documentation . 这是一个例子：

    @Configuration
@PropertySource({ "classpath:mongodb-data-source.properties" })
public class MongodbDataSourceConfig extends AbstractMongoConfiguration {

    @Autowired Environment env;

    @Override
    public String getDatabaseName(){
        return env.getRequiredProperty("mongo.name");
    }

    @Override
    @Bean
    public Mongo mongo() throws Exception {

        ServerAddress serverAddress = new ServerAddress(env.getRequiredProperty("mongo.host"));
        List<MongoCredential> credentials = new ArrayList<>();
        credentials.add(MongoCredential.createScramSha1Credential(
                env.getRequiredProperty("mongo.username"),
                env.getRequiredProperty("mongo.name"),
                env.getRequiredProperty("mongo.password").toCharArray()
        ));
        MongoClientOptions options = new MongoClientOptions.Builder()
            .build();
        return new MongoClient(serverAddress, credentials, options);
    }

}
