Java 无法在行号-1处执行解组

我只想使用hibernate创建一个简单的java程序。我已经为此创建了一个maven项目

我创建了两个文件，一个是hibernate配置文件，另一个是app.java文件

两个文件都在下面

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration SYSTEM "https://www.hibernate-org/dtd/hibernate-configuration-3.0.dtd">

<hibernate-configuration>
  <session-factory>
    <properties name="connection.driver_class">com.mysql.jdbc.Driver</properties>
    <properties name="connection.url">jdbc:mysql://localhost:3306/myhiber</properties>
    <properties name="connection.username">root</properties>
    <properties name="connection.password">root</properties>
    <properties name="dialect">org.hibernate.dialect.MySQLDialect</properties>
    <properties name="hbm2ddl">update</properties>
    <properties name="show_sql">true</properties> 
  </session-factory>    
</hibernate-configuration>

这是我的app.java文件

现在，当我构建并运行app.java时，我遇到了这样一个异常。我是hibernate的初学者，所以不知道如何解决这个问题

我不知道我在这里犯了什么错误。

看起来应该是使用

属性而不是
属性
您需要使用
属性
这是否回答了您的问题？
