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;

// }

}
