Hibernate 抛出 org.hibernate.persister.entity.SingleTableEntityPersister

Question

我正在将 JBoss AS 7 与 H2 数据库一起使用。
我有一个独立的应用程序，它尝试像这样连接到这个数据库。

我的配置文件:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
                                         "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
 <session-factory name="Test">
  <property name="hibernate.connection.driver_class">org.h2.Driver</property>
  <property name="hibernate.connection.url">jdbc:h2:mem:test</property>
  <property name="hibernate.dialect">org.hibernate.dialect.H2Dialect</property>
  <mapping class="Kunde" resource="Kunde.hbm.xml"/>
  <mapping class="Mitarbeiter" resource="Mitarbeiter.hbm.xml"/>
 </session-factory>
</hibernate-configuration>

我的映射文件是:

<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">

            <column name="NACHNAME" />
        </property>
    </class>
</hibernate-mapping>

我的实体类:

public class Kunde {
    long id;
    String vorname;
    String nachname;
    String firma;

    public long getId() {
        return id;
    }

    public void setId(long id) {
        this.id = id;
    }

    public String getVorname() {
        return vorname;
    }

    public void setVorname(String vorname) {
        this.vorname = vorname;
    }

    public String getNachname() {
        return nachname;
    }

    public void setNachname(String nachname) {
        this.nachname = nachname;
    }

    public String getFirma() {
        return firma;
    }

    public void setFirma(String firma) {
        this.firma = firma;
    }
}

(另一个看起来相似)。

我的测试代码:

public static void main(String[] args) {
    try {
        // This step will read hibernate.cfg.xml and prepare hibernate for
        // use
        Configuration configuration = new Configuration();
        configuration.configure();
        ServiceRegistry serviceRegistry = new ServiceRegistryBuilder()
                .applySettings(configuration.getProperties())
                .buildServiceRegistry();
        SessionFactory sessionFactory = configuration
                .buildSessionFactory(serviceRegistry);

        Session session = sessionFactory.openSession();

        // Create new instance of Kinde and set values in it by reading them
        // from form object
        System.out.println("Inserting Record");
        Kunde kunde = new Kunde();
        kunde.setId(1);
        kunde.setVorname("A");
        kunde.setNachname("N");
        kunde.setFirma("Privat");
        session.save(kunde);
        System.out.println("Done");

        // Actual insertion will happen at this step
        session.flush();
        session.close();
    } catch (Exception e) {
        System.out.println(e.getMessage());
    }
}

异常(exception):

任何的想法？

更新:

愚蠢的我 :)

我打印了整个堆栈跟踪，这表明我的类路径不完整:

Caused by: java.lang.ClassNotFoundException: javassist.util.proxy.MethodFilter

我添加了 javaassist JAR，现在工作正常。

对不起。

Answer 1

可能你需要使用 javassistjar 文件；我使用了 javassist-3.10.0.GA.jar 并且这个错误消失了
