Question

我已阅读：org.xml.sax.SAXParseException; lineNumber: 17; columnNumber: 61; Attribute "value" must be declared for element type "property"并且我已在每个标记上添加了value属性，但仍然会发生异常。当我尝试从Configuration.configure()方法配置hibernate配置文件时会发生这种情况。

hibernate.cfg.xml中：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory>
    <property name="hibernate.dialect" value="org.hibernate.dialect.MySQLDialect"/>
    <property name="hibernate.connection.driver_class" value="com.mysql.jdbc.Driver"/>
    <property name="hibernate.connection.url" value="jdbc:mysql://localhost:3306/team_db?zeroDateTimeBehavior=convertToNull"/>
    <property name="hibernate.connection.username" value="root"/>
    <property name="hibernate.connection.password" value=""/>
    <property name="hibernate.cache.use_second_level_cache" value="true"/>
    <property name="hibernate.cache.use_query_cache" value="true"/>
    <property name="hibernate.cache.provider_class" value="org.hibernate.cache.ehcache.EhCacheRegionFactory"/>
    <property name="hibernate.cache.region.factory_class" value="org.hibernate.cache.ehcache.EhCacheRegionFactory"/>
    <property name="hibernate.show_sql" value="true"/>
    <property name="hibernate.hbm2ddl.auto" value="create"/>
    <property name="hibernate.connection.isolation" value="4"/>
    <property name="hibernate.jdbc.batch_size" value="100"/>

    <!--Mappings-->
    <mapping class = "com.gmail.physicistsarah.test.TestObject"/>
</session-factory>

例外：

元素属性没有属性值

尝试从标记中删除值。

<property name="hibernate.dialect" value="org.hibernate.dialect.MySQLDialect"/>

到

<property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>

此外，发布的cfg.xml不会关闭<hibernate-configuration>，也会关闭此内容。

必须为元素类型属性声明属性值
