请帮忙看看是哪写错了`。谢谢
package com.pojo;

public class Myproject {
private int id;
private String username;
private String password;
private String email;
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}

}
我写了 getusername方法啊

Answer 1

原因可能是你的工程里，Myproject类中的userName这个成员变量没有getter方法，所以Hibernate就没有办法取得userName的值，当然就不能存入数据库，因此报错

Answer 2

你的Myproject类里没有getUserName()这个方法。

Answer 3

你xml里面有空格
