struts2+hibernate+spring注解版框架搭建以及简单测试(方便脑补)

2018-01-02 14:35:46 浏览数 (1)

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:

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">

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;

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:

7:配置好之后开始写实体类po下面的实体类;(注解方式配置实体类,配置如下所示):

代码语言:javascript复制
 1 package com.bie.po;
 2 
 3 import javax.persistence.Column;
 4 import javax.persistence.Entity;
 5 import javax.persistence.GeneratedValue;
 6 import javax.persistence.GenerationType;
 7 import javax.persistence.Id;
 8 import javax.persistence.Table;
 9 
10 /** 
11 * @author 作者:别先生
12 * @version 创建时间:2017年6月8日 上午11:55:43 
13 * 类说明 
14 *     1:使用注解完成实体类的配置
15 *     2:用户对应数据库的t_user表
16 */
17 @Entity
18 @Table(name = "t_user")
19 public class User {
20 
21     private Integer id;//主键编号
22     private String name;//姓名
23     private String account;//账号
24     private String password;//密码
25     
26     //设置主键,然后设置主键自增
27     @Id
28     @GeneratedValue(strategy=GenerationType.AUTO)
29     @Column(name="t_userId")
30     public Integer getId() {
31         return id;
32     }
33     public void setId(Integer id) {
34         this.id = id;
35     }
36     
37     @Column(name="t_userName")
38     public String getName() {
39         return name;
40     }
41     public void setName(String name) {
42         this.name = name;
43     }
44     
45     @Column(name="t_userAccount")
46     public String getAccount() {
47         return account;
48     }
49     public void setAccount(String account) {
50         this.account = account;
51     }
52     
53     @Column(name="t_userPwd")
54     public String getPassword() {
55         return password;
56     }
57     public void setPassword(String password) {
58         this.password = password;
59     }
60     
61 }

8:配置一下struts2的配置文件,配置如下所示:

代码语言:javascript复制
 1 <?xml version="1.0" encoding="UTF-8" ?>
 2 <!DOCTYPE struts PUBLIC
 3     "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
 4     "http://struts.apache.org/dtds/struts-2.0.dtd">
 5 
 6 <struts>
 7     <!-- struts2-core-2.3.8.jar ==》org.apache.struts2==》default.properties -->
 8     
 9     <!-- 表示struts2的action由spring来生成 -->
10     <constant name="struts.objectFactory" value="spring"></constant>
11   
12 
13 </struts>

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......
