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;注意第304行struts2注解配置;

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:

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;

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: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:

9:配置好上面的验证一下,将项目加载到tomcat中,然后启动tomcat看看是否报错,我这里不报错,就不做多叙述了;
至此,ssh注解版框架就搭建成功,接下来就可以进行简单测试了......
10:测试的话,先写一个index.jsp页面,页面代码如下所示:
代码语言:javascript复制 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 <%@ taglib prefix="s" uri="/struts-tags"%>
5 <%
6 //获取绝对路径路径 :路径path
7 String path = request.getContextPath();
8 //基本路径:http://localhost:8080/
9 String basePath = request.getScheme() "://"
10 request.getServerName()
11 ":" request.getServerPort() path "/";
12 //保存到session中
13 session.setAttribute("basePath", basePath);
14 %>
15
16 <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
17 <html>
18 <head>
19 <base href="<%=basePath %>" />
20 <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
21 <title>测试crm</title>
22 </head>
23 <body>
24
25 <a href="${basePath }user/queryById.action?userId=1">点击查看个人信息</a>
26 <h1>个人信息如下所示:</h1>
27 <ul>
28 <li>用户编号:${user.userId }</li>
29 <li>用户姓名:${user.userName }</li>
30 <li>用户账号:${user.userAccount }</li>
31 <li>用户密码:${user.userPwd }</li>
32 <li>用户部门:${user.dept.deptName }</li>
33 </ul>
34
35
36
37 </body>
38 </html>
11:页面点击超链接之后访问到struts2的action层,下面先给出action层的代码;
代码语言:javascript复制 1 package com.bie.action;
2
3 import org.apache.struts2.convention.annotation.Action;
4 import org.apache.struts2.convention.annotation.Namespace;
5 import org.apache.struts2.convention.annotation.ParentPackage;
6 import org.apache.struts2.convention.annotation.Result;
7 import org.springframework.beans.factory.annotation.Autowired;
8
9 import com.bie.po.User;
10 import com.bie.service.UserInfoService;
11 import com.opensymphony.xwork2.ActionContext;
12 import com.opensymphony.xwork2.ActionSupport;
13
14 /**
15 * @author 作者:别先生
16 * @version 创建时间:2017年6月8日 下午4:27:30
17 * 类说明
18 */
19 @ParentPackage("struts-default")
20 @Namespace("/user")
21 public class UserAction extends ActionSupport{
22
23 private static final long serialVersionUID = 1L;
24
25 //自动注入到ioc容器中
26 @Autowired
27 private UserInfoService userInfoService;
28
29 private int id;
30 public void setId(int id) {
31 this.id = id;
32 }
33 public int getId() {
34 return id;
35 }
36
37 @Action(
38 value = "queryById",
39 results = {
40 @Result(name="success",location="/index.jsp")
41 }
42 )
43 public String queryById(){
44
45 //调用service层的方法进行查询
46 User user = userInfoService.queryById(id);
47
48 //将查询的信息保存到session中
49 ActionContext.getContext().getSession().put("user", user);
50
51 return "success";
52 }
53
54
55 }
12:数据传输到action中,action对数据进行封装之后传到service层进行数据业务逻辑处理,这里写一下service层的代码;对service层的代码和dao层的代码先写接口,然后再写实现接口的类;
代码语言:javascript复制 1 package com.bie.service;
2
3 import com.bie.po.User;
4
5 /**
6 * @author 作者:别先生
7 * @version 创建时间:2017年6月8日 下午3:43:03
8 * 类说明
9 */
10
11 public interface UserInfoService {
12
13 /***
14 * 根据用户编号查询
15 * @param id
16 * @return
17 */
18 public User queryById(int id);
19 }
代码语言:javascript复制 1 package com.bie.service.impl;
2
3 import org.springframework.beans.factory.annotation.Autowired;
4 import org.springframework.stereotype.Service;
5
6 import com.bie.dao.UserInfoDao;
7 import com.bie.po.User;
8 import com.bie.service.UserInfoService;
9
10 /**
11 * @author 作者:别先生
12 * @version 创建时间:2017年6月8日 下午3:43:13
13 * 类说明
14 */
15 @Service
16 public class UserInfoServiceImpl implements UserInfoService{
17
18 //自动注入到ioc容器中
19 @Autowired
20 private UserInfoDao userInfoDao;
21
22 public User queryById(int id) {
23
24 //直接调用dao层的方法查询之后返回到action层
25 return userInfoDao.queryById(id);
26 }
27
28
29 }
13:数据传输到dao层之后开始和数据库里的数据表进行交互和操作;
代码语言:javascript复制 1 package com.bie.dao;
2
3 import com.bie.po.User;
4
5 /**
6 * @author 作者:别先生
7 * @version 创建时间:2017年6月8日 下午4:35:20
8 * 类说明
9 */
10
11 public interface UserInfoDao {
12
13 /**
14 * 根据用户编号进行查询
15 * @param userId
16 * @return
17 */
18 public User queryById(int userId);
19 }
代码语言:javascript复制 1 package com.bie.dao.impl;
2
3 import org.hibernate.SessionFactory;
4 import org.springframework.beans.factory.annotation.Autowired;
5 import org.springframework.stereotype.Repository;
6
7 import com.bie.dao.UserInfoDao;
8 import com.bie.po.User;
9
10 /**
11 * @author 作者:别先生
12 * @version 创建时间:2017年6月8日 下午4:35:46
13 * 类说明
14 */
15 @Repository
16 public class UserInfoDaoImpl implements UserInfoDao{
17
18 //自动注入到ioc容器中
19 @Autowired
20 private SessionFactory sessionFactory;
21
22 public User queryById(int id) {
23
24 User user = (User) sessionFactory.getCurrentSession().get(User.class, id);
25
26 return user;
27 }
28
29 }
演示效果如下所示:
ssh注解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......
