引起错误的原因

request.setAttribute("user",user);

user.java

package com.min.test;

public class User {
    private String Name;
    private String Password;


    public User(String name, String password) {
        Name = name;
        Password = password;
    }

    public String getName() {
        return Name;
    }
    public void setName(String name) {
        Name = name;
    }
    public String getPassword() {
        return Password;
    }
    public void setPassword(String password) {
        Password = password;
    }

}
