private Integer eno; //员工编号和empno有啥区别？为什么不直接写empno？

这个项目用的就是struts1，几年前的架构了，我就学习struts1，在项目上就做了一个练习。Emp类：
package com.surekam.emp.model;
import java.util.Date;
/**
* 员工类
* @author Administrator
*
*/
public class Emp {
private Integer eno; //员工编号
private String ename; //员工姓名
private String job; //职位
private Integer mgr;
private Date hiredate; //入职日期
private Double sal; //工资
private Double comm; //奖金
private Dept dept; //部门级联属性
///////////////查询条件/////////////////
private Date startTime; //开始时间
private Date endTime; //结束时间
private Double maxSal; //最高工资
private Double minSal; //最低工资
public Emp(Integer empno, String ename, String job, int mgr, Date hiredate,
Double sal, Double comm) {
super();
this.eno = empno;
this.ename = ename;
this.job = job;
this.mgr = mgr;
this.hiredate = hiredate;
this.sal = sal;
this.comm = comm;
}
public Emp() {
super();
// TODO Auto-generated constructor stub
}
public String getEname() {
return ename;
}
public void setEname(String ename) {
this.ename = ename;
}
public String getJob() {
return job;
}
public void setJob(String job) {
this.job = job;
}
public Date getHiredate() {
return hiredate;
}
public void setHiredate(Date hiredate) {
this.hiredate = hiredate;
}
public Double getSal() {
return sal;
}
public void setSal(Double sal) {
this.sal = sal;
}
public Double getComm() {
return comm;
}
public void setComm(Double comm) {
this.comm = comm;
}
public Dept getDept() {
return dept;
}
public void setDept(Dept dept) {
this.dept = dept;
}
public Date getStartTime() {
return startTime;
}
public void setStartTime(Date startTime) {
this.startTime = startTime;
}
public Date getEndTime() {
return endTime;
}
public void setEndTime(Date endTime) {
this.endTime = endTime;
}
public Double getMaxSal() {
return maxSal;
}
public void setMaxSal(Double maxSal) {
this.maxSal = maxSal;
}
public Double getMinSal() {
return minSal;
}
public void setMinSal(Double minSal) {
this.minSal = minSal;
}
public Integer getMgr() {
return mgr;
}
public void setMgr(Integer mgr) {
this.mgr = mgr;
}
public Integer getEmpno() {
return eno;
}
public void setEmpno(Integer empno) {
this.eno = empno;
}
public Integer getEno() {
return eno;
}
public void setEno(Integer eno) {
this.eno = eno;
}
}

No getter method for property: "empno" of bean: "emp"
emp这个类中没有empno的get方法
