回滚无法使用hibernate

Question

我正在尝试使用hibernate的logback,看起来很简单,但我无法让它工作

的hibernate.cfg.xml

    <!-- DB Properties -->
    <property name="dialect">org.hibernate.dialect.MySQLDialect</property>
    <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
    <property name="hibernate.show_sql">true</property>
    <property name="hibernate.transaction.factory_class">org.hibernate.transaction.JDBCTransactionFactory</property>
    <property name="hibernate.current_session_context_class">thread</property>

    <!-- DB Connection -->
     <property name="hibernate.connection.url"> XXXXXXXXXXXXX</property>
    <property name="connection.username">XXXXXXXXXX</property>
    <property name="connection.password">XXXXXXXXXX</property>


    <!-- c3p0 config  -->

    <property name="connection.provider_class">org.hibernate.connection.C3P0ConnectionProvider</property>     
    <property name="hibernate.c3p0.acquire_increment">1</property>
    <property name="hibernate.c3p0.idle_test_period">100</property>
    <property name="hibernate.c3p0.min_size">10</property>
    <property name="hibernate.c3p0.max_statements">50</property>
    <property name="hibernate.c3p0.timeout">1800</property>


</session-factory>

Answer 1

您看到的控制台输出是因为您的休眠配置中有以下内容：

<property name="hibernate.show_sql">true</property>

这告诉 hibernate 将 sql 准备好的语句记录到控制台。

很难从你的问题中判断 logback 日志记录是否工作正常，否则，但如果不是，这里有一个非常好的（如果有点过时；只需更新版本号）教程来启动和运行它。

编辑

如果上述教程不起作用，那么您可能正在使用 Hibernate 4 版本。

在 hibernate 的更高版本中，日志记录框架从 slf4j 切换到 JBoss 日志记录。这意味着 slf4j 不再是 Hibernate 依赖项。

您需要将最新的 slf4j JAR 添加到类路径中。
