IDEA Maven ：第一个Maven 小项目

艾玛！有点小激动！

排除了各种小错误，调出来了第一个Maven 小项目；

虽然功能简单，但是还是好想记录一下，哈哈~

参考博客

若新建项目后，没有出现src文件夹，是因为缺失 pom.xml 文件，

如果没有，就新建一个

<?xml version="1.0" encoding="UTF-8"?>

划重点！！！

      <scope>test</scope>

    <dependency>
      <groupId>mysql</groupId>

      <version>4.12</version>
    </dependency>

    <dependency>
      <groupId>org.hibernate</groupId>
      <artifactId>hibernate-core</artifactId>
      <version>5.2.6.Final</version>
    </dependency>

hibernate.cfg.xml 文件也略有区别

<?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>
  <session-factory>
    <!--  mysql驱动  -->
    <property name="connection.driver_class">com.mysql.jdbc.Driver</property>
    <!--  mysql连接URL  -->
    <property name="connection.url">jdbc:mysql://localhost:3306/test?charset=UTF-8</property>

    <property name="connection.username">root</property>
    <property name="connection.password">root</property>

    <!--  数据库方言  -->
    <property name="dialect">org.hibernate.dialect.MySQLDialect</property>

    <!--  显示sql语句  -->
    <property name="show_sql">true</property>

    <!--  格式化sql语句  -->
    <property name="format_sql">true</property>

    <!--  根据需要创建数据库  -->
    <property name="hbm2ddl.auto">create</property>

    <mapping class="com.xubaifu.GoodsEntity"/>
  </session-factory>
</hibernate-configuration>

锵锵锵！就这样成功啦！
