persistencecontext使查询为空

我最近改变了我的JPA设计：

的persistence.xml 

<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.0"
    xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd">
    <persistence-unit name="flightfaq" transaction-type="JTA">
        <provider>org.hibernate.ejb.HibernatePersistence</provider>
        <properties>
            <property name="hibernate.archive.autodetection" value="class, hbm" />
            <property name="hibernate.connection.username" value="root" />
            <property name="hibernate.connection.password" value="password" />
            <property name="hibernate.connection.url" value="jdbc:mysql://localhost:3306/flightfaq" />
            <property name="hibernate.connection.driver_class" value="com.mysql.jdbc.Driver" />
            <property name="hibernate.hbm2ddl.auto" value="update" />
            <property name="hibernate.c3p0.min_size" value="5" />
            <property name="hibernate.c3p0.max_size" value="20" />
            <property name="hibernate.c3p0.timeout" value="300" />
            <property name="hibernate.c3p0.max_statements" value="50" />
            <property name="hibernate.c3p0.idle_test_period" value="3000" />
            <property name="hibernate.show_sql" value="true" />
            <property name="hibernate.format_sql" value="true" />
            <property name="hibernate.dialect" value="org.hibernate.dialect.MySQLInnoDBDialect"/>
            <property name="use_sql_comments" value="true" />
            <property name="jadira.usertype.autoRegisterUserTypes"
                value="true" />
        </properties>
    </persistence-unit>
</persistence>

道的

@Singleton
@LocalBean
@Startup
public class AircraftTypeDaoImpl implements AircraftTypeDao {

    @PersistenceContext
    private EntityManager em;

    /** JPQL query to find a {@link AircraftType} given its OACI name */
    private static final String JPQL_FIND_BY_TYPE = "SELECT a FROM AircraftType a WHERE a.typeOACI=:typeOACI";

    /** JPQL query to find all {@link AircraftType} */
    private static final String JPQL_FIND_ALL = "SELECT a FROM AircraftType a";

    public AircraftType find(String typeOACI) throws DAOException {
        AircraftType aircraftType = null;
        Query findQuery = em.createQuery(JPQL_FIND_BY_TYPE).setParameter(
                "typeOACI", typeOACI);
        aircraftType = (AircraftType) findQuery.getSingleResult();
        return aircraftType;
    }

    @SuppressWarnings("unchecked")
    public List<AircraftType> findAll() throws DAOException {
        return em.createQuery("SELECT a FROM AircraftType a").getResultList();
    }

}

托管bean简化

@ManagedBean
@ViewScoped
public class MissionHandler implements Serializable {

    private static final long serialVersionUID = 2462652101518266609L;

    private Mission mission;

    private List<FlightFeasibilityException> exceptions;

    @EJB
    private AircraftTypeDaoImpl aircraftTypeDao;

    public MissionHandler() {
    }

    @PostConstruct
    public void init() {
        /** Create an empty mission */
        mission = new Mission();
        /** Create an empty list of exceptions */
        exceptions = new ArrayList<FlightFeasibilityException>();
        /** get aircraft types from the database */
        aircraftTypes = aircraftTypeDao.findAll();
        System.out.println("dump types");
        for (AircraftType type : aircraftTypes) {
            System.out.println(type.getTypeOACI());
        }
        System.out.println("init done");
    }

}

与我的other post相反，Web服务器加载完美。 （我关闭另一个，我不知道发生了什么） 但是在我的托管bean的@PostConstruct方法中（在加载应用程序的第一个xhtml页面时称为direclty），aircraftTypes列表为空！ 我知道JPQL查询是可以的，因为它非常简单，并且在此设计更改之前可以正常工作。我的猜测是创建的实体管理器不在我的“flightfaq”数据库上查询。我真的不明白，因为我只有一个持久单元。

以下是TomEE在启动时显示的日志 在查询飞机类型时，您将看到休眠日志，但在打印列表内容时不会发生任何事情

您是否尝试过为持久性单元提供显式名称？有人告诉我，即使你只有一个由TomEE的开发人员David Blevins提供的名字，最好提供这个名字; - ）

虽然我确实怀疑它会解决你的问题。

顺便说一句，如果您将查询的创建更改为添加结果类型的类，则可以省略强制转换

em.createQuery("SELECT a FROM AircraftType a", AircraftType.class).getResultList();

这些方法始终返回TypedQuery<AircraftType>

然后你可以避免警告信息。

我发现了问题。 它与我的TomEE Web服务器配置有关。 我需要在tomee.xml文件中描述我的dataSource（我做了）并将这些定义复制到部署在TomEE部署webapps和其他东西的硬盘目录中的openejb.xml文件中。 我认为这个副本是自动完成的（从tomee.xml到openejb.xml）

中的所有内容都非常详细

请注意，现在可以使用以下方式执行此操作：

  • @ ManagedBean / @ ViewScoped
  • @ Singleton / @ Startup / @ LocalBean
