现在请大家看看Dept的实体类和对应的映射信息:
Dept实体类
package org.entity;
import java.util.HashSet;
import java.util.Set;
/**
* Dept entity. @author MyEclipse Persistence Tools
*/
public class Dept implements java.io.Serializable {
// Fields
private Integer deptno;
private String dname;
private String loc;
private Set emps = new HashSet(0);
// Constructors
/** default constructor */
public Dept() {
}
/** full constructor */
public Dept(String dname, String loc, Set emps) {
this.dname = dname;
this.loc = loc;
this.emps = emps;
}
// Property accessors
public Integer getDeptno() {
return this.deptno;
}
public void setDeptno(Integer deptno) {
this.deptno = deptno;
}
public String getDname() {
return this.dname;
}
public void setDname(String dname) {
this.dname = dname;
}
public String getLoc() {
return this.loc;
}
public void setLoc(String loc) {
this.loc = loc;
}
public Set getEmps() {
return this.emps;
}
public void setEmps(Set emps) {
this.emps = emps;
}
}
对应的是Dept.hbm信息
