整合SSH框架实现简单登录

SSH整合的大体结构：我们将Struts2和hibernate交给spring来管理

  

 

创建好web项目之后，首先当然是先引入需要的pom节点，需要的pom的节点可以在Maven官方仓库中下载https://mvnrepository.com/

  当然以下是我自己准备好的一份pom节点，复制进去下载完即可使用

在src下创建resource目录，并在创建好的目录中创建相应的XML文件

hibernate.cfg.xml(当applicationtext.xml中出现Hibernate相关配置时，就可以不需要此文件。。当然此时的applicationtext.xml中文件是存在Hibernate配置)

 

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

创建Java包，创建实体类以及相关的xml文件

  

Pojo层

package cn.ssh.pojo;


import javax.persistence.*;

public class User {

  private Integer id;

  private String name;

  private String password;

  public Integer getId() {
    return id;
  }

  public void setId(Integer id) {
    this.id = id;
  }
  public String getName() {
    return name;
  }

  public void setName(String name) {
    this.name = name;
  }


  public String getPassword() {
    return password;
  }

  public void setPassword(String password) {
    this.password = password;
  }
}

xml version="1.0" encoding="UTF-8"?>
DOCTYPE hibernate-mapping PUBLIC
        "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
        "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">
<hibernate-mapping package="cn.ssh.pojo">
    <class name="User" table="`User`">
        <id name="id" type="java.lang.Integer" >

        id>
        <property name="name" type="java.lang.String" />
        <property name="password" type="java.lang.String">
            <column name="`password`">column>
        property>
    class>
hibernate-mapping>

dao层

 

public interface UserDao {
   public  User findUser(String name,String password);
}

 在实现类中我们继承HibernateDaoSupport类，这个类主要给我们提供了一些增删改的方法

package cn.ssh.dao;

import cn.ssh.pojo.User;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;
import org.springframework.stereotype.Repository;

import java.util.List;

/**
 * @author: wmj
 * @Data: 2018-10-30 14:44
 **/

public class UserDaoImpl extends HibernateDaoSupport implements  UserDao {
    @Override
    public User findUser(String name, String password) {
        List users = (List) this.getHibernateTemplate()
                .find("from User u WHERE u.name=? AND u.password=?", name, password);
        if (users.size()>0){
            return  users.get(0);
        }else{
            return null;
        }
    }
}

service层

  

 

 action层

  UserAction继承ActionSupport 

package cn.ssh.action;

import cn.ssh.pojo.User;
import cn.ssh.service.UserService;
import com.opensymphony.xwork2.ActionContext;
import com.opensymphony.xwork2.ActionSupport;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.stereotype.Controller;

import java.util.Map;

/**
 * @author: wmj
 * @Data: 2018-10-30 15:25
 **/
@Controller
public class UserAction extends ActionSupport {
    @Autowired

    private UserService userService;

    private  String name;  //名称
    private  String password;   //密码
    private  String message;   //信息提示  
    public  String login(){
        User user = userService.findUser(name, password);
        ActionContext context=ActionContext.getContext();
　　　　　　//用户名为空
        if (name==null || name.equals("")){
            this.setMessage("请输入名称");
            return  "login";
        }
　　　　　　　　//密码为空
        if (password==null || password.equals("")){
            this.setMessage("请输入密码");
            return  "login";
        }
　　　　　　//将登陆的用户保存在session集合中

        Map session = context.getSession();
        if (null!=user){
            session.put("user",user);
            return "index";
        }
        this.setMessage("登录失败");
        return "login";
    }



  //要有getter和setter方法，否则映射不到
    public UserService getUserService() {
        return userService;
    }

    public void setUserService(UserService userService) {
        this.userService = userService;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }

    public String getMessage() {
        return message;
    }

    public void setMessage(String message) {
        this.message = message;
    }
}

创建相应的JSP页面

  创建login.jsp 登陆页面

<%--
  Created by IntelliJ IDEA.
  User: wumengjie
  Date: 2018/10/30
  Time: 15:32
  To change this template use File | Settings | File Templates.

<%@ page contentType="text/html;charset=UTF-8" language="java" %>

    密码:<s:password name="password"/>
    <s:submit value="提交"/>
s:form>
<s:property value="message">s:property>
body>
html>

这时配置Struts.xml文件

xml version="1.0" encoding="UTF-8" ?>
DOCTYPE struts PUBLIC
        "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
        "http://struts.apache.org/dtds/struts-2.3.dtd">
<struts>
    <constant name="struts.ui.theme" value="simple"/>
    <constant name="struts.i18n.encoding" value="UTF-8"/>
  <package name="default" namespace="/" extends="struts-default">
      <action name="login" class="cn.ssh.action.UserAction" method="login">
          <result name="login">/login.jspresult>
          <result name="index">/index.jspresult>
      action>
  package>
struts>

登录成功页面：index.jsp

成功<s:property value="#session.user.name">s:property>

 

配置TomCat

点击Edit Configurations....

  

 

点击加号，找到Tomcat Server，配置本地tomcat

 

 配置相关信息

 

点击带有exploded的即可，把tomcat集成到项目中

也可以点击 Deployment------点击加号-----artifact 

 

 

什么都不需要改，点击apply即可

 

启动tomcat，测试

当没有输入密码或输入错误密码会进行提示，因为在UserAction中有message字段，对字段进行赋值，在页面获取即可
