java.lang.IllegalArgumentException: No bean specified

今天使用Struts1.x + Hibernate3.2集成的時候出了個以下錯誤：No bean specified

 

不能保存外鍵！！！！找不到相對應得formbean！但是formbean中有對應得類！

 

EmployeeForm類

  private Employee employee = new Employee();

public Employee getEmployee() {
return employee;
}


public void setEmployee(Employee employee) {
this.employee = employee;
}
 

Employee.java

public class Employee implements java.io.Serializable {


// Fields


private Integer empno;
private Dept dept = new Dept();  //隨後發現問題出在這裏，此處沒有實例化
private String username;
private String realname;
private String pass;
private Date createdate;
private Integer isdel;

//省略setter/getter方法

 

 

Hibernate: select dept0_.deptno as deptno0_, dept0_.dname as dname0_, dept0_.isdel as isdel0_ from FinancialDB.dbo.dept dept0_ where dept0_.isdel = 0
