今天使用Struts1.x + Hibernate3.2集成的时候出了个以下错误：No bean specified
不能保存外键！！！！找不到相对应得formbean！但是formbean中有对应得类！
EmployeeForm类
| private Employee employee = new Employee(); public Employee getEmployee() { return employee; } public void setEmployee(Employee employee) { this.employee = employee; } |
| public class Employee implements java.io.Serializable { // Fields private Integer empno;private Dept dept = new Dept(); //随后发现问题出在这里，此处没有实例化 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
