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

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)

</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
