Unable to locate appropriate constructor on class 。。。各路英雄快看看

软件环境hibernate3.2 Spring2.5

Unable to locate appropriate constructor on class

DAO代码如下：

String selectHql = "select new TUser(user.userId,user.TOrganization,user.userName,user.gender, user.duty, user.phone,user.address,user.createdDate,user.remark) from TUser as user ";

//取得当前页的数据
List datas = getSession().createQuery(selectHql)
.setFirstResult(offset)
.setMaxResults(pagesize)
.list();
实体类
TUser含有对应的构造参数。

public TUser(Integer userId, TOrganization TOrganization, String userName,
Integer gender, String duty, String phone, String address,
Timestamp createdDate, String remark) {
this.userId = userId;
this.TOrganization = TOrganization;
this.userName = userName;
this.gender = gender;
this.duty = duty;
this.phone = phone;
this.address = address;
this.createdDate = createdDate;
this.remark = remark;

}

到底是什么原因？？？？无参构造，属性方法齐全。

大家支招！

把默认构造函数写上试试.

public TUser(){
}

看看你的参数类型是否都是匹配

private Integer userId;
private TOrganization TOrganization;
private String userName;
private Integer gender;
private String duty;
private String phone;
private String address;
private String remark;
private Integer modifyCount;
private Timestamp createdDate;
private String createdBy;
private String createdPrgName;
private Timestamp lastModifyDate;
private String updatedPrgName;
private String updatedBy;
private Integer flgCount;

还真没找出不匹配的。无参构造函数是有的。

还是没辙呀！

望楼主将这句代码:

String selectHql = "select new TUser(user.userId,user.TOrganization,user.userName,user.gender, user.duty, user.phone,user.address,user.createdDate,user.remark) from TUser as user "; 

打印出来看看是否有问题~~

建议楼主把Integer 都换成 Long试一下。Hibernate3.2整数返回的好像都是Long类型

[jerryForever]

还有确定一下Timestamp 类型是否正确，是不是应该使用java.util.Date

要写默认的构造函数，把默认构造函数写上试试.



public TUser(){ }

同意。
