我正在将一个web-app部署到一个连接到mysql容器的tomcat容器中。当我部署战争时，在创建MySQL数据库（通过hibernate.cfg.xml插入）之后，一切正常。
但是，如果我想将我的网络应用程序连接到我将战争部署到webapps /文件夹后创建的新数据库，我有以下几行：

我该如何解决这个问题？
这是我的hibernate.cfg.xml文件：
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC^M
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"^M
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">^M
<hibernate-configuration>^M
<session-factory>^M
<property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>^M
<property name="hibernate.connection.password">pass</property>^M
<property name="hibernate.connection.url">jdbc:mysql://172.19.0.3:3306/shine</property>^M
<property name="hibernate.connection.username">root</property>^M
<property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
<property name="hibernate.current_session_context_class">thread</property>
<mapping class="entities.Responsabile"/>
<mapping class="entities.Utente"/>
<!-- <mapping class="entities.Prodotti"/> -->
</session-factory>
</hibernate-configuration>
我的目标是从我最初的.war创建一个新的（复制的）网络应用程序。所以，我已经重命名了我的战争，将其部署到webapps /，并编辑了hibernate.cfg.xml。如果我重命名我的战争并将其指向初始数据库，那就没关系了。当我指向另一个数据库时出现此问题。实际上，在日志中，存在初始Web应用程序（/ ShoppingAT）的“上下文路径”。
