运行后，表建出来了，但出现了上面的错误！

Answer 1

你能确定所有的表都建好了吗?org.jbpm.identity.User, jbpm中有一个User类, 映射的表是jbpm_id_user, 下面是这个JBPM的user类的映射文件, 如果你自己的类库中也有一个类User, 那么你在HQL中使用User的时候, 就需要使用带包的全名.<hibernate-mapping default-access="field">  <class name="org.jbpm.identity.User" 
         table="JBPM_ID_USER"
         discriminator-value="U">
    <id name="id" column="ID_"><generator class="native" /></id>
    <discriminator type="char" column="CLASS_"/>
    <property name="name" column="NAME_"/>
    <property name="email" column="EMAIL_"/>
    <property name="password" column="PASSWORD_"/>
    <set name="memberships" cascade="all">
      <key column="USER_" />
      <one-to-many class="org.jbpm.identity.Membership" />
    </set>
    <set name="permissions" cascade="all" table="JBPM_ID_PERMISSIONS">
      <key column="ENTITY_" foreign-key="none" />
      <element type="org.jbpm.identity.hibernate.PermissionUserType">
        <column name="CLASS_"/>
        <column name="NAME_"/>
        <column name="ACTION_"/>
      </element>
    </set>
  </class></hibernate-mapping>

Answer 2

配置文件时拷贝过来的吗？
<property name="hibernate.cache.provider_class">org.hibernate.cache.HashtableCacheProvider</property>
看看配置这个没？没有的话加上看看

Answer 3

 org.hibernate.cache.NoCachingEnabledException 我也出了这个异常 正在解决中
