Question

我知道StackOverflow中有关于此主题的其他问题，我读过它们但我无法摆脱这个错误。

我在JBoss-as-7.1.1 Final中部署我的Web应用程序。这是一个Maven项目。

当我进入sapo-ear，rigth click，run as，maven install，它说＆＃34; buildsufulfull＆＃34;。然后我尝试在JBoss中完整发布它，然后它说：

23:59:26,009 ERROR [org.jboss.msc.service.fail] (MSC service thread 1-1) MSC00001: Failed to start service jboss.persistenceunit."SAPo-ear.ear/SAPo-ejb.jar#sapo": org.jboss.msc.service.StartException in service jboss.persistenceunit."SAPo-ear.ear/SAPo-ejb.jar#sapo": Failed to start service

据我所知，这可能是由persistence.xml和Adminstrador类之间的不一致引起的。

这是我的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="sapo">
    <jta-data-source>java:jboss/datasources/sapo</jta-data-source>
    <class>sapo.entities.Administrador</class>
    <class>sapo.entities.Almacen</class>
    <class>sapo.entities.AtributoValor</class>
    <class>sapo.entities.Comentario</class>
    <class>sapo.entities.Estandar</class>
    <class>sapo.entities.Mensaje</class>
    <class>sapo.entities.Producto</class>
    <class>sapo.entities.RolEnAlmacen</class>
    <class>sapo.entities.CatCompleja</class>
    <class>sapo.entities.ProductoGenerico</class>
    <class>sapo.entities.TransaccionInterna</class>
    <class>sapo.entities.TransaccionExterna</class>


    <properties>
        <!-- Properties for Hibernate -->
        <property name="hibernate.hbm2ddl.auto" value="update" />
        <property name="hibernate.show_sql" value="false" />
        <property name="hibernate.dialect" value="org.hibernate.dialect.MySQLDialect" />
    </properties>
</persistence-unit>

这是我的Administrador类

@Entity
public class Administrador extends Usuario {

public Administrador(){
}

public Administrador(String nick, String password, String nombre,
        String mail, String direccion, Date fechaNacimiento,
        String linkImagen) {
    super(nick, password, nombre, mail, direccion, fechaNacimiento, linkImagen);
    // TODO Auto-generated constructor stub
}


}

Usuario是一个抽象类

@Entity
@Inheritance(strategy=InheritanceType.TABLE_PER_CLASS)
public abstract class Usuario {
    @Id
    @GeneratedValue(strategy=GenerationType.TABLE)
    @Basic(optional = false)
    private Long id;
    //attribs, Getters setters and other methods
}

最奇怪的是来自jboss堆栈跟踪的这一行

java.lang.ClassNotFoundException: uy.edu.fing.tsi2.sapo.entities.Administrador

此目录全部更改为sapo.entities.Administrador，长路径来自旧版本。我删除了这个旧项目并从git再次克隆它，我还删除了C：\ Program Files \ jboss-as-7.1.1.Final \ standalone \ deployments中的所有文件，但堆栈跟踪一直在抛弃这条旧路径。

我的队友正在使用相同的配置，从同一个git存储库克隆而没有任何问题，而我已经堆积了这个。

Answer 1

最后我解决了它，这是pom.xml中maven项目配置中的一个问题，我们遇到了来自artefact和parent的组ID的问题。

我没有确切的答案，因为我的队友是谁解决了它，我会问她并稍后更详细地更新这个答案。

Answer 2

如果您的xml文件中有条目以及相应类的注释，那么有时它会导致问题。尝试删除相应类的注释或xml条目之一，然后再次运行。希望这会有所帮助。
