SSH框架搭建demo

SSH框架搭建demo
1、新建Java Web工程

2、添加Struts2.1框架支持

去除冲突包：antlr-2.7.2.jar

一般项目加上这三个包足够，后期可以视项目需求增加支持包：

2.1配置web.xml文件
增加struts2的配置，增加容器对struts2的初始化。增加代码如下：这些配置代码对于struts2是不变的，直接复制到web.xml即可。
1. 
2. <filter>
3. <filter-name>struts2</filter-name>
4. <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
5. </filter>
6. <filter-mapping>
7. <filter-name>struts2</filter-name>
8. <url-pattern>/*</url-pattern>
9. </filter-mapping>
2.2配置struts.xml文件
1. <?xml version="1.0" encoding="UTF-8" ?>
2. <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd">
3. <struts>
5. </struts>
3、添加Spring框架支持

一般添加这6个支持包

效果图：

3.1配置web.xml文件
初始化加载spring资源配置文件
1. 
2. <context-param>
3. <param-name>contextConfigLocation</param-name>
4. <param-value>
5. /WEB-INF/applicationContext.xml
6. </param-value>
7. </context-param>
9. 
10. <listener>
11. <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
12. </listener>
13. <listener>
14. <listener-class>org.springframework.web.context.request.RequestContextListener</listener-class>
15. </listener>
4、配置数据源
此处用oracle数据库作为数据源：
1. create user ssh identified by 1234;
3. grant dba to ssh with admin option;
5. create table people (
6. id varchar2(32) primary key,
7. username varchar2(32),
8. password varchar2(32)
9. );
11. insert into PEOPLE (ID, USERNAME, PASSWORD) values ('1', 'John', '1234');
12. insert into PEOPLE (ID, USERNAME, PASSWORD) values ('2', 'Tom', '1234');
驱动包直接用oracle自带的jdbc驱动包即可，路径如上图所示。
5、添加Hibernate框架支持

删除冲突包：asm.jar和cglib-2.1.3.jar

0%

切换到MyEclipse Database Explorer视图：

选择我们建立的链接SSH，点开，找到对应的table，people，右键

6、代码设计
为了方便管理代码，先建立四个package，如下图：

在com.ssh.dao下建立一个接口，IPeopleDAO.java
1. package com.ssh.dao;
3. import java.util.List;
5. import com.ssh.people.People;
7. public interface IPeopleDAO {
9. public People findById(String id);
11. public List findByUsername(Object username);
13. public void save(People people);
15. }
把PeopleDAO拖到com.ssh.dao.impl下

PeopleDAO.java里要加implements IPeopleDAO

修改后：

在com.ssh.service下建立IPeopleService.java
1. package com.ssh.service;
3. import com.ssh.people.People;
5. public interface IPeopleService {
7. public People getPeopleById(String id);
9. public People getPeopleByUsername(String username);
11. public void addPeople(People people);
13. }
在com.ssh.service.impl下建立PeopleService.java
1. package com.ssh.service.impl;
3. import java.util.List;
5. import com.ssh.dao.IPeopleDAO;
6. import com.ssh.people.People;
7. import com.ssh.service.IPeopleService;
9. public class PeopleService implements IPeopleService{
11. private IPeopleDAO peopleDAO;
13. public People getPeopleById(String id) {
14. return peopleDAO.findById(id);
15. }
17. public People getPeopleByUsername(String username) {
18. List list = peopleDAO.findByUsername(username);
19. if(list.size() == 0){
20. return null;
21. }else{
22. return (People)list.get(0);
23. }
24. }
26. public void addPeople(People people) {
27. peopleDAO.save(people);
28. }
30. public IPeopleDAO getPeopleDAO() {
31. return peopleDAO;
32. }
34. public void setPeopleDAO(IPeopleDAO peopleDAO) {
35. this.peopleDAO = peopleDAO;
36. }
37. }
效果图：

接着要在applicationContext.xml中添加一个bean的信息
1. <bean id="peopleService" class="com.ssh.service.impl.PeopleService">
2. <property name="peopleDAO">
3. <ref bean="PeopleDAO"></ref>
4. </property>
5. </bean>
整个applicationContext.xml的全部内容
1. <?xml version="1.0" encoding="UTF-8"?>
2. <beans
3. xmlns="http://www.springframework.org/schema/beans"
4. xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
5. xmlns:p="http://www.springframework.org/schema/p"
6. xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">
9. <bean id="dataSource"
10. class="org.apache.commons.dbcp.BasicDataSource">
11. <property name="driverClassName"
12. value="oracle.jdbc.OracleDriver">
13. </property>
14. <property name="url"
15. value="jdbc:oracle:thin:@localhost:1521/orcl">
16. </property>
17. <property name="username" value="ssh"></property>
18. <property name="password" value="1234"></property>
19. </bean>
20. <bean id="sessionFactory"
21. class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
22. <property name="dataSource">
23. <ref bean="dataSource" />
24. </property>
25. <property name="hibernateProperties">
26. <props>
27. <prop key="hibernate.dialect">
28. org.hibernate.dialect.Oracle9Dialect
29. </prop>
30. </props>
31. </property>
32. <property name="mappingResources">
33. <list>
34. <value>com/ssh/people/People.hbm.xml</value></list>
35. </property>
36. </bean>
38. <bean id="PeopleDAO" class="com.ssh.dao.impl.PeopleDAO">
39. <property name="sessionFactory">
40. <ref bean="sessionFactory" />
41. </property>
42. </bean>
44. <bean id="peopleService" class="com.ssh.service.impl.PeopleService">
45. <property name="peopleDAO">
46. <ref bean="PeopleDAO"></ref>
47. </property>
48. </bean>
50. </beans>
创建处理action的文件，新建com.ssh.action包，新建LoginAction.java文件
1. package com.ssh.action;
3. import com.opensymphony.xwork2.ActionSupport;
4. import com.ssh.people.People;
5. import com.ssh.service.IPeopleService;
7. public class LoginAction extends ActionSupport{
9. private String username;
10. private String password;
11. private IPeopleService peopleService;
12. public String getUsername() {
13. return username;
14. }
15. public void setUsername(String username) {
16. this.username = username;
17. }
18. public String getPassword() {
19. return password;
20. }
21. public void setPassword(String password) {
22. this.password = password;
23. }
24. public IPeopleService getPeopleService() {
25. return peopleService;
26. }
27. public void setPeopleService(IPeopleService peopleService) {
28. this.peopleService = peopleService;
29. }
31. public String execute(){
32. People people = peopleService.getPeopleByUsername(username);
33. if(people == null) return "error";
34. if(people.getPassword().equals(password))
35. return "success";
36. else return "error";
37. }
39. public void validate(){
40. if(username == null || username.length() == 0){
41. super.addActionError("用户名不能为空");
42. }
43. if(password == null || password.length() == 0){
44. super.addActionError("密码不能为空");
45. }
46. }
47. }
配置applicationContext.xml文件：
1. <bean id="loginAction" class="com.ssh.action.LoginAction" scope="prototype">
2. <property name="peopleService" ref="peopleService"></property>
3. </bean>
配置struts.xml文件：
1. <?xml version="1.0" encoding="UTF-8" ?>
2. <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd">
3. <struts>
4. <package name="com" extends="struts-default" namespace="/">
5. <action name="login" class="loginAction">
6. <result name="success">/index.jsp</result>
7. <result name="input">/login.jsp</result>
8. <result name="error">/login.jsp</result>
9. </action>
10. </package>
11. </struts>
新增login.jsp文件：
1. <%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
2. <%@taglib prefix="s" uri="/struts-tags"%>
3. <%
4. String path = request.getContextPath();
5. String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
6. %>
7. <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
8. <html>
9. <head>
10. <base href="<%=basePath%>">
11. <title>登录页面</title>
12. </head>
13. <body>
14. <s:form name="form" action="login.action" method="post">
15. <s:textfield name="username" label="username"></s:textfield>
16. <s:password name="password" label="password"></s:password>
17. <s:submit label="submit"></s:submit>

7、部署运行

7.1Tomcat服务器

7.2去除antlr-2.7.2.jar冲突包

apache-tomcat-7.0.54webappsSSH_DemoWEB-INFlib目录下

7.3整理jar包

把apache-tomcat-7.0.54webappsSSH_DemoWEB-INFlib目录下的jar包全部复制出来，这个就是SSH框架所需的jar包。

然后把jar.zip中的jar包导入即可。

7.4运行访问

http://localhost:8080/SSH_Demo/login.jsp

8、常见问题

1）关于 myeclipse 里面没有 add struts capabilities 问题解决方法

高版本的 myeclipse 里面的 add struts capabilities 在如下路径中：（当你加载过一次之后，这个 add struts capabilities就不会出现。

解决方法：把 .project 文件的关于struts的配置删除掉即可
