spring data mongo-未定义名为“mongo Template”的bean

Question

我有一个spring data 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 {

原因：org.springframework.beans.factory.nosuchbeandefinitionexception：在org.springframework.beans.factory.support.defaultlistablebeanfactory.getbeandefinition（defaultlistablebeanfactory.java:698)~[spring-beans-4.2.4.release.jar:4.2.4.release]在org.springframework.beanfactory.support.abstractbeanfactory.getmergedlocalbeandefinition（tory.support.abstractbeanFactory.dogetBean（abstractbeanFactory.java:284)~[spring-beans-4.2.4.release.jar:4.2.4.release]在org.springframework.beans.factory.support.abstractbeanFactory.getbean（abstractbeanFactory.197)~[spring-beans-4.2.4.release.jar]在org.springframework.beans.factory.1977)~[spring-beans-4.2.4.release.release]在org.springframework.beans.factory.support.beandefinition

@enablemongorepositories注释将在启动时触发存储库bean的创建，但您仍然需要注册MongoDB连接并创建注入这些存储库的MongoTemplate实例。请参阅Spring Data MongoDB文档。这里有一个例子：

@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);
    }

}
