LoginService.java代码
package com.ssh.service;

        return loginDao;

    public void setLoginDao(LoginDao loginDao) {
        this.loginDao = loginDao;
    }

User.java 代码
package com.ssh.pojo;

public class User {
   
    private int id;
   
    private String username;
   
    private String password;

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public String getUsername() {
        return username;
    }

    public void setUsername(String username) {
        this.username = username;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }
}
User.hbm.xml代码：
<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
    "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
    "http://hibernate.
<hibernate-mapping >
    <class name="com.ssh.pojo.User" table="user">
        <id name="id">
            <generator class="native"/>
        </id>
        <property name="username"/>
        <property name="password" />
    </class>
</hibernate-mapping>
LoginDao.java代码
package com.ssh.dao;

import java.util.List;

import org.springframework.context.ApplicationContext;
import org.springframework.orm.hibernate3.HibernateTemplate;



public class LoginDao {
   
    private HibernateTemplate hibernateTemplate;
    public List getUser(){
        
        List list = hibernateTemplate.find("from User");
        System.out.print(list);
        return list;
    }
    public HibernateTemplate getHibernateTemplate() {
        return hibernateTemplate;
    }

    public void setHibernateTemplate(HibernateTemplate hibernateTemplate) {
        this.hibernateTemplate = hibernateTemplate;
    }
}
其中的  List list = hibernateTemplate.find("from User");这一句报出空指针错误
