没有从{classpath*:META-INF/persistence.xml}解析的持久性单元

Question

使用Spring Core 3.0.5,Hibernate 3.6.0.这个问题的标题是在使用我正在维护的应用程序启动Tomcat webserver(6.0.29)时引发的java.lang.IllegalStateException的消息.

applicationContext.xml说:

<bean id="emf" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean" scope="singleton">
   <property name="jpaVendorAdapter">
     <bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter" />
  </property>
</bean>

persistence.xml位于项目包含的jar文件的META-INF目录中.Expedissimo.web.war有一个带有.jar的WEB-INF/classes文件夹.

启动服务器时的完整异常回溯是:

persistence.xml说:

<persistence 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" version="2.0">
<persistence-unit name="serv2010pool" transaction-type="RESOURCE_LOCAL">
<provider>org.hibernate.ejb.HibernatePersistence</provider> 
    <properties>
        <property name="hibernate.show_sql" value="false" /> 
        <property name="hibernate.format_sql" value="true" /> 
        <property name="use_sql_comments" value="true" /> 
        <property name="hibernate.autocommit" value="false" /> 
        <property name="javax.persistence.jdbc.driver"     value="oracle.jdbc.OracleDriver"/>
        <property name="hibernate.dialect" value="org.hibernate.dialect.Oracle10gDialect"/>
        <property name="hibernate.connection.insee.poolName" value="serv2010pool" />
        <property name="hibernate.connection.provider_class" value=
            "fr.insee.config.hibernate.InseeConnectionProvider"/>           
    </properties>
</persistence-unit>

当在批处理兄弟项目中在Spring外部使用时,可以正确地找到并解析相同的持久性单元描述符

    emf = Persistence.createEntityManagerFactory("serv2010pool");

批处理项目与Web项目一样,包括Serv2010-1.0.jar,它具有META-INF/persistence.xml.所有带注释的类都在这个常见的jar中.

在Eclipse v3.6中部署会引发异常..war中的WEB-INF/classes /文件夹没有persistence.xml文件.手动添加它并重新启动服务器没有帮助.

任何的想法？我在这里没有技巧,谢谢你提供任何技巧.CChris

Answer 1

这通常意味着Spring无法找到persistence.xml.确保persistence.xml与您的类路径相关的META-INF.这可能意味着您必须将文件放在WEB-INF\classes\META-INF中,即使它看起来很奇怪.

Answer 2

如果您正在使用Maven,则应将META-INF文件夹放在其中src/main/resources,一旦文件存在,问题就会消失.
