ibatis报错，很奇怪，求大神帮忙

Question

现在项目中用的是ibatis，第一次接触，这两天一直在报错，都要疯了，请大神帮忙看看吧。
配置如下：
resultMap="cpVoucherResultCheckIn"
parameterClass="elementCondition">
select master.* from cp_voucher master where
master.sum_cp_voucher_id is null
and master.is_valid='1'

master.PAY_PWD_STATE = #passwdStatus#

参数类中对应属性如下：

    private String passwdStatus;
public String getPasswdStatus() {
    return passwdStatus;
}

public void setPasswdStatus(String passwdStatus) {
    this.passwdStatus = passwdStatus;
}

报错信息如下：
