我创建了一个简单的休眠应用程序,并在运行时遇到上述异常(我使用的是hibernate 5.4.0.Final
版本)。如果我使用版本4.3.5.Final
而不是5.4.0.Final
hibernate.cfg.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory>
<property name="connection.driver_class">oracle.jdbc.driver.OracleDriver</property>
<property name="connection.url">jdbc:oracle:thin:@192.168.0.998:1522:TEST</property>
<property name="connection.username">test</property>
<property name="connection.password">test</property>
<property name="hbm2ddl.auto">update</property>
<property name="show_sql">true</property>
<mapping class="com.mahipal.model.WsdlMst"/>
</session-factory>
</hibernate-configuration>
踪迹:
Exception in thread "main"

答案 0 :(得分:0)
检查必须定义实体类的Hibernate配置文件:
例如
或者您必须使用以下方式将类显式添加到配置中
例如 configuration.addClass(annotations.Users.class) 读取映射作为应用程序resourceName addResource用于以声明方式添加hbml.xml文件 configuration.addResource(“ myFile.hbm.xml”); //不是hibernateAnnotations.cfg.xml
