这是我在 stackoverflow 中的第一篇文章：我是 hibernate 的新手，事实上下面是我在 hibernate 中的第一个代码：当我运行我的主类时，我反复收到“无法解析映射文档”错误。以下是供您参考的代码，请帮我解决这个问题。
配置文件：
<?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>
映射文件：
<?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="Employee" table="EMPLOYEE"/>
<id name="emp_id" type="int" column="emp_id"/>
<property name="emp_name">

<property name="emp_branch">
<column name="emp_branch"/>
</property>
<property name="emp_Salary">
<column name="emp_salary"/>
</property>
<property name="emp_fav_dgt">
<column name="emp_fav_dgt"/>
</property>
</hibernate-mapping>
Pojo类：
public class Employee {
private int emp_id;
private String emp_name;
private String emp_branch;
private int emp_Salary;
private int emp_fav_dgt;
public int getEmp_Salary() {
return emp_Salary;
}
public void setEmp_Salary(int emp_Salary) {
this.emp_Salary = emp_Salary;
}
public String getEmp_branch() {
return emp_branch;
}
public void setEmp_branch(String emp_branch) {
this.emp_branch = emp_branch;
}
public int getEmp_fav_dgt() {
return emp_fav_dgt;
}
public void setEmp_fav_dgt(int emp_fav_dgt) {
this.emp_fav_dgt = emp_fav_dgt;
}
public int getEmp_id() {
return emp_id;
}
public void setEmp_id(int emp_id) {
this.emp_id = emp_id;
}
public String getEmp_name() {
return emp_name;
}
public void setEmp_name(String emp_name) {
this.emp_name = emp_name;
}
}
主类：
public class Main {
public static void main(String[] args) {
System.out.println("asdf");
SessionFactory sessionFactory = null;
Transaction ts = null;
Session session = null;
Configuration conf = null;
try{
conf = new org.hibernate.cfg.Configuration().configure();
sessionFactory = conf.buildSessionFactory();
session =sessionFactory.openSession();
Employee customer = new Employee();
customer.setEmp_id(1);
customer.setEmp_name("one");
customer.setEmp_branch("old");
customer.setEmp_Salary(1000);
customer.setEmp_fav_dgt(2);
session.save(customer);
ts.commit();
}
catch(Exception e){
e.printStackTrace();;
}
finally{
session.close();
}
}
}
