[英]Hibernate Exception : Could not parse configuration: hibernate.cfg.xml
[英]Exception:Could not parse configuration: hibernate.cfg.xml
其實我正在嘗試做hibernate日志記錄。 這是我的hibernate.cfg.xml文件
<?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="hbm2ddl.auto">update</property>
<property name="dialect">org.hibernate.dialect.MySQLDialect</property>
<property name="connection.url">jdbc:mysql://localhost:3306/temp</property>
<property name="connection.username">root</property>
<property name="connection.password">root</property>
<property name="connection.driver_class">com.mysql.jdbc.Driver</property>
<mapping resource="employee.hbm.xml"/>
</session-factory>
</hibernate-configuration>
這是例外......
log4j:WARN No appenders could be found for logger (org.hibernate.cfg.Environment).
log4j:WARN Please initialize the log4j system properly.

這是employee.hbm.xml
<?xml version='1.0' encoding='UTF-8'?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping>
<class name="com.subhas.mypackage.Employee" table="emp1000">
<id name="id">
<generator class="assigned"></generator>
</id>
<property name="firstName"></property>
<property name="lastName"></property>
</class>
</hibernate-mapping>
這是我的主要課程
public class StoreData {
public static void main(String[] args) {
//creating configuration object
Configuration cfg=new Configuration();
cfg.configure("hibernate.cfg.xml");
//creating session factory object
SessionFactory factory=cfg.buildSessionFactory();
//creating session object
Session session=factory.openSession();
//creating transaction object
Transaction transaction=session.beginTransaction();
Employee employee=new Employee();
employee.setId(5000);
employee.setfName("Subhas");
employee.setlName("Gupta");
//persisting the object
session.persist(employee);
//commit the transaction object
transaction.commit();
session.close();
System.out.println("Data Saved Successfully");
}
}
我無法找到完美的解決方案。 有人能幫助我嗎? 謝謝。
嘗試將DOCTYPE更改為:
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
我不確定,但我認為你缺少一些log4J配置的BasicConfiguration.configure(),那么你就不會遇到log4J初始化異常。
我的朋友錯誤只是導致選擇了不正確的方言。 請確保它是正確的,您還需要在映射文件中添加列屬性。
<class name="Employee" table="EMPLOYEE">
<id name="id" column="ID">
<generator class="assigned"></generator>
</id>
<property name="name" column="NAME"></property>
<property name="mobile" column="MOBILE"></property>
<property name="email" column="EMAIL"></property>
</class>
我相信你的錯誤會得到解決......
