Question

这是我的配置：

<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
    "-//Hibernate/Hibernate Configuration DTD//EN"
    "http://www.hibernate.org/dtd/hibernate-configuration-5.0.dtd">
<hibernate-configuration
        xmlns="http://www.hibernate.org/xsd/hibernate-configuration"
        xsi:schemaLocation="http://www.hibernate.org/xsd/hibernate-configuration hibernate-configuration-4.0.xsd"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <session-factory>
    <!-- Database connection settings -->
    <property name="connection.driver_class">com.mysql.jdbc.Driver</property>
    <property name="connection.url">jdbc:mysql://localhost:3306/test</property>
    <property name="connection.username">root</property>
    <property name="connection.password"></property>

    <!-- JDBC connection pool (use the built-in) -->
    <property name="connection.pool_size">1</property>

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

    <!-- Enable Hibernate's automatic session context management -->
    <property name="current_session_context_class">thread</property>

    <!-- Disable the second-level cache  -->
    <property name="cache.provider_class">org.hibernate.cache.internal.NoCacheProvider</property>

    <!-- Echo all executed SQL to stdout -->
    <property name="show_sql">true</property>

    <!-- Drop and re-create the database schema on startup -->
    <property name="hbm2ddl.auto">update</property>
    <mapping resource="org/hibernate/tutorial/domain/Event.hbm.xml"/>

    <mapping class="Mapping.AccountMap"
  </session-factory>
</hibernate-configuration>

我读到我应该更改＆＃34; Doctype＆＃34;我从我找到的其他答案中做到了，但是这个错误发生了：

无法在RESOURCE hibernate.cfg.xml中的第8行和第63行执行解组。消息：cvc-elt.1：无法找到元素声明＆＃39; hibernate-configuration＆＃39;。

Answer 1

你的dtd url是假的...好像hibernate-configuration-5.0.dtd不存在...使用这个：

http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd

更改整个标题：

<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
    "-//Hibernate/Hibernate Configuration DTD//EN"
    "http://www.hibernate.org/dtd/hibernate-configuration-5.0.dtd">
<hibernate-configuration
        xmlns="http://www.hibernate.org/xsd/hibernate-configuration"
        xsi:schemaLocation="http://www.hibernate.org/xsd/hibernate-configuration hibernate-configuration-4.0.xsd"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

以

<?xml version='1.0' encoding='utf-8'?> <!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD//EN" "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd"> <hibernate-configuration>

Answer 2

尝试添加此标头块。它适用于我，还检查XML文件中的解析错误。

<?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">

这里我发布一些示例xml文件可能会对你有帮助。

<hibernate-configuration>

    <session-factory>

    <!-- Database connection settings -->
    <property name="connection.driver_class">com.mysql.jdbc.Driver</property>
    <property name="connection.url">jdbc:mysql://localhost:3306/hibernate</property>
    <property name="connection.username">root</property>
    <property name="connection.password">root</property>

    <!-- JDBC connection pool (use the built-in) -->
    <property name="connection.pool_size">1</property>

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

    <!-- Disable the second-level cache  -->
    <property name="cache.provider_class">org.hibernate.cache.internal.NoCacheProvider</property>

    <!-- Echo all executed SQL to stdout -->
    <property name="show_sql">true</property>

    <!-- Drop and re-create the database schema on startup -->
    <property name="hbm2ddl.auto">create</property>

    <!-- Names the annotated entity class -->
    <mapping class="org.java.dto.UserDetails"/>


</session-factory>

</hibernate-configuration>

找不到元素的声明＆＃39; hibernate-configuration＆＃39;但它存在
