解決方案無效persistence.xml

Question

我正在使用eclipse中的spring jpa hibernate項目。我有一個錯誤在我的persistence.xml文件，但我不知道確切位置：

我的persistence.xml

<?xml version="1.0" encoding="UTF-8"?> 
<persistence xmlns="http://java.sun.com/xml/ns/persistence" version="2.0"> 
    <persistence-unit name="hibernatePersistenceUnit" transaction-type="RESOURCE_LOCAL"> 
     <properties> 
      <property name="hibernate.hbm2ddl.auto" value="update" /> 
      <property name="show_sql">true</property> 
      <property name="hibernate.dialect" value="org.hibernate.dialect.MySQL5InnoDBDialect" /> 
     </properties> 
     <mapping-file>META-INF/orm.xml</mapping-file> 

     </persistence-unit> 
</persistence> 

我得到錯誤像這樣：

javax.persistence.PersistenceException: Invalid persistence.xml. 
Error parsing XML (line-1 : column -1): cvc-complex-type.4: Attribute 'value' must appear on element 'property'. 
Error parsing XML (line-1 : column -1): cvc-complex-type.2.1: Element 'property' must have no character or element information item [children], because the type's content type is empty. 
Error parsing XML (line-1 : column -1): cvc-complex-type.2.4.d: Invalid content was found starting with element 'mapping-file'. No child element is expected at this point.

嘗試把映射文件屬性之前：

<?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="hibernatePersistenceUnit" transaction-type="RESOURCE_LOCAL"> 
     <mapping-file>META-INF/orm.xml</mapping-file> 
     <properties> 
      <property name="hibernate.hbm2ddl.auto" value="update" /> 
      <property name="show_sql" value="true"/> 
      <property name="hibernate.dialect" value="org.hibernate.dialect.MySQL5InnoDBDialect" /> 
     </properties> 
     </persistence-unit> 
</persistence>
