DataAccessService的使用

@Repository

public class DataAccessService
{
    private static final Logger LOGGER = Logger.getLogger(DataAccessService.class);

    private static final String DEFAULT_HOSTNAME = "localhost";

    @PersistenceContext(unitName="SIRCCPersistenceUnit")
    private EntityManager entityManager;

@Configuration
public class A{
@Autowired
private ApplicationContext context = null;
public static DataAccessService dataAccessService;
 private static void init(boolean isHttps)
    {
  dataAccessService = (DataAccessService) context .getBean("DataAccessService");
   }
}

另一个位置是使用@autowire自动连接的

xml依赖关系层次结构

我找不到这个错误的确切原因。我是否遗漏了pom.xml中的任何内容，或者是版本问题？ 请提出解决办法

persistence.xml

<persistence-unit name="SIRCCPersistenceUnit" transaction-type="RESOURCE_LOCAL">
        <provider>org.apache.openjpa.persistence.PersistenceProviderImpl</provider>
        <mapping-file>META-INF/queries.xml</mapping-file> 
        <class></class>        
        <exclude-unlisted-classes>true</exclude-unlisted-classes>
        <properties>
            <property name="openjpa.Log" value="DefaultLevel=ERROR, Tool=ERROR" />
            <property name="openjpa.jdbc.DBDictionary" value="sybase" />
            <property name="openjpa.DataCache" value="true" />
        </properties>
    </persistence-unit>

</persistence>

org.apache.openjpa.persistence.PersistenceProviderImpl
META-INF/querys.xml
真的

您是否有任何服务类名DataAccessService？查看由以下原因引起的错误

：org.springframework.beans.factory.BeanCreationException:创建名为“dataAccessService”的bean时出错

是的。注释为@repository您是否在其他任何地方使用过此类，我的意思是您是否在任何地方使用了

自动连线

公共静态dataAccessService dataAccessService；dataAccessService=（dataAccessService）localDataAccessContext.getBean（“dataAccessService”）；像这样使用，您可以将该类和调用的其他类发布到

dataAccessService
