java - org.hibernate.MappingException : java. lang.ClassNotFoundException:员工

Question

我是 hibernate 新手，正在使用 hibernate 版本 4.3.4 JAR 文件。我正在尝试使用 intelliJ 社区版中的 mySQL 服务器执行简单的 Hibernate 程序。以下是我的文件。

POJO 文件

package TestPackage;
public class Employee {
private int id;
private String firstName;
private String lastName;
private int salary;

public Employee() {}
public Employee(String fname, String lname, int salary) {
    this.firstName = fname;
    this.lastName = lname;
    this.salary = salary;
}
public int getId() {
    return id;
}
public void setId( int id ) {
    this.id = id;
}
public String getFirstName() {
    return firstName;
}
public void setFirstName( String first_name ) {
    this.firstName = first_name;
}
public String getLastName() {
    return lastName;
}
public void setLastName( String last_name ) {
    this.lastName = last_name;
}
public int getSalary() {
    return salary;
}
public void setSalary( int salary ) {
    this.salary = salary;
}
}

请帮忙。

在 hibernate 映射文件和 check.use 中使用完整的类路径: class name="TestPackage.Employee"

<class name="TestPackage.Employee" table="EMPLOYEE">
