数据访问服务

@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;

数据访问服务的使用

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

另一个地方是使用@autowire 自动接线的

pom.xml 依赖层次结构

我找不到这个错误的确切原因。我错过了 pom.xml 中的任何内容，还是版本问题？请提出解决方案

持久性.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>
