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
applicationContext.xml全局配置文件

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"?> <!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd"> <hibernate-configuration> <session-factory> <!--jdbc连接四要素--> <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property> <property name="hibernate.connection.url">jdbc:mysql:///hibernate</property> <property name="hibernate.connection.username">root</property> <property name="hibernate.connection.password">0000</property> <!--在控制台上展示sql--> <property name="show_sql">true</property> <!--格式化sql--> <property name="format_sql">true</property> <property name="hbm2ddl.auto">update</property> <property name="current_session_context_class">thread</property> <!--加载的配置文件--> <mapping resource="cn/ssh/pojo/User.hbm.xml"></mapping> </session-factory> </hibernate-configuration>
至于Struts.xml文件我们等到需要的时候在进行配置
web.xml(需要修改web.xml的头部)
<?xml version="1.0" encoding="UTF-8"?> <web-app id="WebApp_9" version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"> <display-name>Archetype Created Web Application</display-name> <!--配置环境参数--> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:applicationContext.xml</param-value> </context-param> <!--配置监听器--> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!--过滤器--> <filter> <filter-name>OpenSessionInViewFilter</filter-name> <filter-class>org.springframework.orm.hibernate3.support.OpenSessionInViewFilter</filter-class> </filter> <filter-mapping> <filter-name>OpenSessionInViewFilter</filter-name> <url-pattern>*.action</url-pattern> </filter-mapping> <filter> <filter-name>struts2</filter-name> <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class> </filter> <filter-mapping> <filter-name>struts2</filter-name> <url-pattern>/*</url-pattern> </filter-mapping>
指定项目启动后的首页面，如果不是index.jsp页面需要添加 <welcome-file-list> <welcome-file>login.jsp</welcome-file> </welcome-file-list> </web-app>
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" > <generator class="identity"/><!--主键生成策略--> </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<User> users = (List<User>) 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" %> <%@taglib uri="/struts-tags" prefix="s"%> <html> <head> <title>Title</title> </head> <body> <s:form action="login.action" method="post"> 用户名:<s:textfield name="name"/> <br/> 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.jsp</result> <result name="index">/index.jsp</result> </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
