我们正在将一些批处理作业从 Spring XD M5 移至 1.0.0 版本。

在创建和部署作业时，我们在自动装配 Spring Data 存储库（在本例中为 Neo4J）时遇到了 cglib 代理功能的问题。

堆栈跟踪的尾部：

Spring Data repository 接口注释@Repository如下：

@Repository
public interface DatasetRepository extends GraphRepository<Dataset> 
{
    public Dataset findOneById(String id);
    public Dataset findOneByName(String name);
}

以及触发异常的 bean 类中相应的 autowired 属性：

    @Autowired
    private DatasetRepository datasetRepo;

bean 本身在我们的 XD 作业 XML 中定义如下：

<bean id="myBean" class="com.mycompany.MyBean"/>

以及配置 bean（在作业 cfg XML 中扫描的组件）：

@Configuration
@EnableNeo4jRepositories({ "com.mycompany.repositories" })
public class CustomNeo4jConfiguration implements InitializingBean

我们部署到 XD lib 文件夹中的 Spring Data Neo4J 版本如下：

spring-data-neo4j      : 3.2.0.RELEASE
spring-data-neo4j-rest : 3.2.0.RELEASE

设置全部在开发 PC 上（目前），XD 在分布式模式下运行：

  • redis 服务器
  • Zookeeper 服务器 (1x)
  • Oracle 作业存储库（目前为本地 XE 实例）
  • 1x 管理员和 1x 容器

任何有关作业配置、Spring Data 存储库或 XD 容器的帮助将不胜感激。

谢谢

删除 GraphRepository 上的 @Repository 注释，你应该没问题。不要忘记启用组件扫描。
