为了之后学习的日子里加深对框架的理解和使用，这里将搭建步奏简单写一下，目的主要是方便以后自己回来脑补；
1:File--->New--->Other--->Maven--->Maven Project--->Next（之后界面如下所示：）
--->Next（点击next之后出现如下界面：选择最后一个 maven-archetype-webapp,然后点击next）
--->Next(点击next之后出现如下界面，然后选择好组织号，工程号，版本号即可)，最后点击Finish
2：maven项目创建好之后会报错，这里先在pom.xml中导入jar包，导入方式如下所示：这个pom配置好之后点击保存会将jar包下载到本地仓库，这个学习maven的时候都配置过，这个自己下去脑补吧；

3：web.xml里面的dtd默认是2.3的，不过2.3的不支持el表达式，所以这里修改为2.5的。配置如下所示：
1 <?xml version="1.0" encoding="UTF-8"?> 2 <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" version="2.5"> 3 <display-name>Archetype Created Web Application</display-name> 4 5 6 <display-name>Archetype Created Web Application</display-name> 7 8 </web-app>
4：项目配置好上面的，接下来开始写代码，首先从web.xml的配置开始，比如struts2的核心过滤器，spring核心配置文件，监听器；
1 <?xml version="1.0" encoding="UTF-8"?> 2 <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" version="2.5"> 3 <display-name>Archetype Created Web Application</display-name> 4 5 6 <display-name>Archetype Created Web Application</display-name> 7 8 <!-- 配置spring的监听器 ,加载本地的springp配置文件--> 9 <context-param> 10 <param-name>contextConfigLocation</param-name> 11 <param-value>classpath:bean-*.xml</param-value> 12 </context-param> 13 14 <!-- 15 spring的监听器 spring-web-3.2.4.RELEASE.jar ==》org.springframework 16 ==》context ==》ContextLoaderListener 17 --> 18 <listener> 19 <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> 20 </listener> 21 22 23 <!-- 24 struts2的核心过滤器 25 1:filter-class ==》 struts2-core-2.3.8.jar ==》org.apache.struts2 26 ==》 dispatcher ==》 ng ==》filter ==》StrutsPrepareAndExecuteFilter 27 --> 28 <filter> 29 <filter-name>struts2Filter</filter-name> 30 <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class> 31 </filter> 32 <filter-mapping> 33 <filter-name>struts2Filter</filter-name> 34 <url-pattern>/*</url-pattern> 35 </filter-mapping> 36 37 </web-app>
5：配置好之后就需要配置一下maven标准格式：在src/main下面创建一个java的文件夹，在src/下面创建一个test，在test下面创建java文件夹，配置如下所示：
6：简单测试一下，将项目发布到tomcat中，启动tomcat,运行之后tomcat不报错，说明项目正常；
7：将spring的配置文件bean-common.xml配置文件放到src/main/resources下面即可（src/main/resources也是根目录）：配置如下所示：
1 <?xml version="1.0" encoding="UTF-8"?> 2 <beans xmlns="http://www.springframework.org/schema/beans" 3 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 4 xmlns:p="http://www.springframework.org/schema/p" 5 xmlns:context="http://www.springframework.org/schema/context" 6 xmlns:aop="http://www.springframework.org/schema/aop" 7 xmlns:tx="http://www.springframework.org/schema/tx" 8 xsi:schemaLocation="http://www.springframework.org/schema/beans 9 http://www.springframework.org/schema/beans/spring-beans.xsd 10 http://www.springframework.org/schema/context 11 http://www.springframework.org/schema/context/spring-context.xsd 12 http://www.springframework.org/schema/aop 13 http://www.springframework.org/schema/aop/spring-aop.xsd 14 http://www.springframework.org/schema/tx 15 http://www.springframework.org/schema/tx/spring-tx.xsd"> 16 17 18 </beans>

8：将struts的配置文件struts.xml配置文件放到src/main/resources下面即可（src/main/resources也是根目录）：配置如下所示：
1 <?xml version="1.0" encoding="UTF-8" ?> 2 <!DOCTYPE struts PUBLIC 3 "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN" 4 "http://struts.apache.org/dtds/struts-2.3.dtd"> 5 6 <struts> 7 8 9 </struts>
1 <?xml version="1.0" encoding="UTF-8" ?>
2 <!DOCTYPE struts PUBLIC
3 "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
4 "http://struts.apache.org/dtds/struts-2.3.dtd">
5
6 <struts>
7
8 <package name="admin_package" extends="struts-default">
9
10 <!-- Ation实例交给spring容器创建 -->
11 <action name="select_*" class="adminAction" method="{1}">
12
13 <!-- 列表展示 -->
14 <result name="success">index.jsp</result>
15
16 </action>
17 </package>
18
19 </struts>
9：配置到第八步，基本结束，开始写代码，创建一个实体类Admin；如下所示：
1 package com.bie.po;
2
3 /**
4 * @author 作者:别先生
5 * @version 创建时间:2017年6月10日 下午2:08:17
6 * 类说明
7 */
8
9 public class Admin {
10
11 private Integer adminId;//管理员编号
12 private String adminName;//管理员姓名
13 private String adminPwd;//管理员密码
14
15 public Integer getAdminId() {
16 return adminId;
17 }
18 public void setAdminId(Integer adminId) {
19 this.adminId = adminId;
20 }
21 public String getAdminName() {
22 return adminName;
23 }
24 public void setAdminName(String adminName) {
25 this.adminName = adminName;
26 }
27 public String getAdminPwd() {
28 return adminPwd;
29 }
30 public void setAdminPwd(String adminPwd) {
31 this.adminPwd = adminPwd;
32 }
33 @Override
34 public String toString() {
35 return "Admin [adminId=" + adminId + ", adminName=" + adminName + ", adminPwd=" + adminPwd + "]";
36 }
37
38
39 }
10：创建好实体类之后配置一个hibernate的映射文件；Admin.hbm.xml,代码如下所示：
1 <?xml version="1.0" encoding="UTF-8" ?> 2 <!DOCTYPE hibernate-mapping PUBLIC 3 "-//Hibernate/Hibernate Mapping DTD 3.0//EN" 4 "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd"> 5 6 <!-- hibernate的实体类映射文件的配置，package包指出总包所在 --> 7 <hibernate-mapping package="com.bie.po"> 8 9 <!-- class的name是实体类的名字，table是数据表名 --> 10 <class name="Admin" table="admin"> 11 <id name="adminId"> 12 <!-- native设置自增 --> 13 <generator class="native"></generator> 14 </id> 15 16 <!-- 非主键的映射 --> 17 <property name="adminName" length="20"></property> 18 <property name="adminPwd" length="20"></property> 19 </class> 20 21 </hibernate-mapping> 22
11：创建好实体类之后开始创建dao层的接口和实现类，如AdminDao接口和AdminDaoImpl实现类；
1 package com.bie.dao;
2
3 import java.util.List;
4
5 import com.bie.po.Admin;
6
7 /**
8 * @author 作者:别先生
9 * @version 创建时间:2017年6月10日 下午2:25:01
10 * 类说明
11 */
12
13 public interface AdminDao {
14
15 /**
16 * 查询管理员的信息
17 * @param admin
18 * @return
19 */
20 public List<Admin> selectAdmin();
21 }
1 package com.bie.dao.impl;
2
3 import java.util.List;
4
5 import org.hibernate.SessionFactory;
6
7 import com.bie.dao.AdminDao;
8 import com.bie.po.Admin;
9
10 /**
11 * @author 作者:别先生
12 * @version 创建时间:2017年6月10日 下午2:25:15
13 * 类说明
14 */
15
16 public class AdminDaoImpl implements AdminDao{
17
18 //IOC容器注入sessionFactory对象
19 private SessionFactory sessionFactory;
20 public void setSessionFactory(SessionFactory sessionFactory) {
21 this.sessionFactory = sessionFactory;
22 }
23
24 public List<Admin> selectAdmin() {
25
26 List<Admin> list = sessionFactory.getCurrentSession().createQuery(" from Admin ").list();
27
28 return list;
29 }
30
31
32 }
12：创建好dao层接口和实现类之后开始创建service层的接口和实现类，如AdminService接口和AdminServiceImpl实现类；
1 package com.bie.service;
2
3 import java.util.List;
4
5 import com.bie.po.Admin;
6

13:当写好service层之后开始写action层AdminAction，这里传递前台页面的参数；代码如下所示：
1 package com.bie.action;
2
3 import java.util.List;
4 import java.util.Map;
5
6 import org.apache.struts2.interceptor.RequestAware;
7
8 import com.bie.po.Admin;
9 import com.bie.service.AdminService;
10 import com.opensymphony.xwork2.ActionSupport;
11
12 /**

17
18 public class AdminAction extends ActionSupport implements RequestAware{
19
20
21 private static final long serialVersionUID = 1L;
22
23 //ioc容器注入
24 private AdminService adminService;
25 public void setAdminService(AdminService adminService) {
26 this.adminService = adminService;
27 }
28
29 // 接收框架运行时候传入的代表request对象的map
30 private Map<String, Object> request;
31 public void setRequest(Map<String, Object> request) {
32 this.request = request;
33 }
34
35
36 //ioc容器注入
37 private Admin admin;
38 public void setAdmin(Admin admin) {
39 this.admin = admin;
40 }
41 public Admin getAdmin() {
42 return admin;
43 }
44
45 public String selectAdmin(){
46
47 List<Admin> list = adminService.selectAdmin();
48
49 //将信息保存到request中
50 request.put("list", list);
51
52 return "success";
53 }
54
55
56 }
14:当后台写完之后开始写前台测试页面：页面如下所示
1 <%@ page language="java" contentType="text/html; charset=UTF-8"
2 pageEncoding="UTF-8"%>
3 <%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
4 <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
5 <html>
6 <head>
7 <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
8 <title>主页显示管理员的信息</title>
9 </head>
10 <body>
11
12 <a href="select_selectAdmin.action">查询所有用户信息</a>
13
14 <center>
15 <table cellspacing="20" cellpadding="20">
16 <tr>
17 <th>管理员编号</th>
18 <th>管理员姓名</th>
19 <th>管理员密码</th>
20 </tr>
21 <c:forEach items="${list }" var="list">
22 <tr>
23 <td>${list.adminId}</td>
24 <td>${list.adminName}</td>
25 <td>${list.adminPwd }</td>
26 </tr>
27 </c:forEach>
28 </table>
29 </center>
30
31 </body>
32 </html>
直接访问index.jsp页面，测试结果如下所示：
ssh配置版框架搭建先到这吧，以后有机会再深学吧。时间过的挺快的，马上就该出去找工作了......
增删改查功能日后有时间再写吧......
