如何将 Tapestry 5 demo(tapestry-hotel-booking) 的数据库更改为 mysql

Question

我将 hibernate.cfg.xml 更改如下：

<!DOCTYPE hibernate-configuration PUBLIC
        "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
        "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
    <session-factory>
        <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
        <property name="hibernate.connection.url">jdbc:mysql://localhost:3306/quickstart</property>
        <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
        <property name="hibernate.connection.username">root</property>
        <property name="hibernate.connection.password">aaa</property>
        <property name="hbm2ddl.auto">update</property>
        <property name="hibernate.show_sql">true</property>
        <property name="hibernate.format_sql">true</property>
    </session-factory>
</hibernate-configuration>

但无法运行并出现以下错误：

[ERROR] ioc.Registry Error invoking constructor public org.apache.tapestry5.internal.hibernate.HibernateSessionSourceImpl(org.slf4j.Logger,java.util.List): org.slf4j.helpers.MessageFormatter.format(Ljava/lang/String;Ljava/lang/Object;)Ljava/lang/String;

等等。

这看起来像是一个类路径问题；您应该验证类路径上是否有所有必需的 JAR，并且没有不必要的 JAR。我相信您的 SLF4J（日志框架）JAR 版本可能不匹配。
