我最近将应用程序从java 1.7升级到1.8.其余的库版本保持不变.升级后我收到以下错误:

Hibernate配置:

<hibernate-configuration>
    <session-factory>
        <property name="hibernate.connection.driver_class">oracle.jdbc.driver.OracleDriver</property>
        <property name="hibernate.connection.url">jdbc:oracle:thin:@ldaps://XXXX,cn=OOOO,dc=WWW</property>
        <property name="hibernate.connection.username">YYYY</property>
        <property name="hibernate.statement_cache.size">0</property>
        <property name="hibernate.connection.password">ZZZZZ</property>
        <property name="hibernate.c3p0.min_size">5</property>
        <property name="hibernate.c3p0.max_size">20</property>

我如何在默认情况下显示Bootstrap的折叠,也就是"汉堡"菜单,但是将它放在浏览器的左侧？

我猜这是在折叠的菜单上,我只是将其更改为如下所示？

<!-- the collapsing menu -->
    <div class="collapse navbar-collapse navbar-left" id="navbar-collapse-1">
      <ul class="nav navbar-nav">
        <li class="active"><a href="#">Home</a></li>
        <li><a href="#">About</a></li>
        <li><a href="#">Contact</a></li>
      </ul>
    </div>
    <!--/.nav-collapse -->
