spring - 找不到该类型的属性 saveAll

Question

我最近开始在我们的一个项目中使用ReactiveCouchbaseRepository(spring-data-couchbase - 3.0.0.M2、spring-boot-starter-parent - 2.0.0.M2)。

我提到了unpublished doc from here并设置项目，但我收到以下错误。

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dummyRepository': Invocation of init method failed; nested exception is org.springframework.data.mapping.PropertyReferenceException: No property saveAll found for type Dummy!

这是有关设置我的项目的相关信息。

@Maven

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.0.0.M2</version>
    <relativePath/> <!-- lookup parent from repository -->
</parent>

...

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-test</artifactId>
        <scope>test</scope>
    </dependency>

    <dependency>
        <groupId>org.springframework.data</groupId>
        <artifactId>spring-data-couchbase</artifactId>
        <version>3.0.0.M2</version>
    </dependency>

@java

//Repository class
public interface DummyRepository extends ReactiveCouchbaseSortingRepository<Dummy, String> {
}

//Model class
public class Dummy {

@Id
private final String id;

@Field
private final String name;

@Field
private final String address;

...
}

//Java config class
@Configuration
@EnableReactiveCouchbaseRepositories
public class CouchbaseDatabaseConfig extends AbstractReactiveCouchbaseConfiguration {

...
}

现在，我确实经历了this和 this但这里我没有在 DummyRepository 类中编写自定义方法。

请注意当我从ReactiveCouchbaseSortingRepository更改为CouchbaseRepository时，一切正常。

感谢您提前提供的帮助。

看来我们只需要添加以下依赖项即可实现 saveAll。

<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-data-couchbase</artifactId> </dependency>
