出错地方：

package com.lottery.model.lottery;



public class DateDataModel2

{

privateString poscode; // 玩法ID

privateLong salmoney; // 当天销售金额

privateLong cashmoney; // 当前兑奖金额



publiclong getSalmoney()

{

returnsalmoney;

}



publicvoid setSalmoney(long salmoney)

{

this.salmoney= salmoney;

}



publicString getPoscode()

{

returnposcode;

}



publicvoid setPoscode(String poscode)

{

this.poscode= poscode;

}



publicvoid setSalmoney(Long salmoney)

{

this.salmoney= salmoney;

}



publicvoid setCashmoney(Long cashmoney)

{

this.cashmoney= cashmoney;

}



publiclong getCashmoney()

{

returncashmoney;

}



publicvoid setCashmoney(long cashmoney)

{

this.cashmoney= cashmoney;

}



}





原因：

setSalmoney()和setCashmoney各2个。



解决：

setSalmoney()和setCashmoney各去掉1个即可。



如下即可解决：

package com.lottery.model.lottery;

publicclass DateDataModel
{
private String
poscode;
// 玩法ID
private Long
salmoney;
// 当天销售金额
private Long
cashmoney;
// 当前兑奖金额

// public long getSalmoney()
// {
// return salmoney;
// }
//
// public void setSalmoney(long salmoney)
// {
// this.salmoney = salmoney;
// }

public String getPoscode()
{
returnposcode;
}

publicvoid setPoscode(String poscode)
{
this.poscode = poscode;
}

public Long getSalmoney() {
returnsalmoney;
}

publicvoid setSalmoney(Long salmoney)
{
this.salmoney = salmoney;
}

publicvoid setCashmoney(Long cashmoney)
{
this.cashmoney = cashmoney;
}

public Long getCashmoney() {
returncashmoney;
}

// public long getCashmoney()
// {
// return cashmoney;
// }
//
// public void setCashmoney(long cashmoney)
// {
// this.cashmoney = cashmoney;
// }

}
