手动整合实现SSH项目开发02

Posted 2020-09-24 注定要成为攻城狮的男人

在bean包下建立User类和User.hbm.xml文件，实现User类和数据库表User的映射关系，具体User类不多说，User.hbm.xml如下：

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE hibernate-mapping PUBLIC
        "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
        "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">


<hibernate-mapping>
　　　//实现User类和表的映射
    <class name="com.whl.bean.User">
        <id name="id" type="java.lang.Integer" column="id">
            <generator class="increment"/>
        </id>
        <property name="username" />
        <property name="userpass"  column="userpass"/>
    </class>
</hibernate-mapping>

7.applicationContext.xml文件中实现前面所有需要注入的对象

 1 <?xml version="1.0" encoding="UTF-8"?>

8 在action类中实现真实的操作，并根据其结果做出相应的应答

package com.whl.action;

import com.opensymphony.xwork2.ActionContext;
import com.opensymphony.xwork2.ActionSupport;
import com.opensymphony.xwork2.ModelDriven;
import com.whl.bean.User;
import com.whl.service.IUserService;

public class UserLoginAction extends ActionSupport implements ModelDriven<User> {

    /**
     * 
     */
    private static final long serialVersionUID = 1L;
    private User user=new User();
    private IUserService userService;

    
    public String userLongin(){
        User u = userService.getUserByNamePass(user.getUsername(), user.getUserpass());
        if (u!=null) {
            ActionContext ac = ActionContext.getContext();
            ac.put("user", u.getUsername());
            return SUCCESS;
        }
        
        return INPUT;
        
    }
    
    public void setUserService(IUserService userService) {
        this.userService = userService;
    }


    @Override
    public User getModel() {
        
        return user;
    }
    

}
