PersistenceUnit中的java多个类

Question

我有一个项目使用另一个项目作为库，两个项目上都有Spring和Hibernate，问题是我需要将第一个项目中的类映射到第二个项目中

这是我得到的一个例外：

Caused by: org.hibernate.hql.internal.ast.QuerySyntaxException: Usuario is not mapped [SELECT u FROM Usuario u WHERE usuario = 'abc' order by idUsuario desc]
    at org.hibernate.hql.internal.ast.util.SessionFactoryHelper.requireClassPersister(SessionFactoryHelper.java:180)

所以我尝试在持久性中映射类。xml，如下所示：

<?xml version="1.0" encoding="UTF-8"?>
<persistence version="1.0"
    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_1_0.xsd">
    <persistence-unit name="default">

    <class>com.planner.pov.model.Usuario</class>
    <class>com.planner.pov.model.LogWork</class>
    <class>com.planner.pov.model.Responsavel</class>
    <class>com.planner.pov.model.GrupoResponsavel</class>
    <class>com.planner.pov.model.Cargo</class>
    <class>com.planner.pov.model.TarefaBackLog</class>
    <class>com.planner.pov.model.ItemBackLog</class>
</persistence-unit>

但是有太多的类需要映射，它们都是链接的。。。 有更好的方法吗

@EDIT

应用程序上下文。xml
