一、开发环境:
(1) OS:Windows 7
(2) DB:MySql 5.1.6
(3) JDK:1.8.0_17
(4) Server:Apache Tomcat 8.0.26
(5) IDE:Eclipse
二、SSH框架版本:
(1) Struts2.3.2
(2) Spring4.0.2
(3) Hibernate5.2.5
注意:我根据需要并没有导入所有JAR 包;
三、配置Sturts2框架:
1.在eclipse新建一个项目news;
2.导入Sturts2.X的jar包;
3.然后配置在WebContext/WEB-INF/web.xml:
<display-name>news</display-name>
<welcome-file-list>
<welcome-file>default.jsp</welcome-file>
</welcome-file-list>
<filter>
<filter-name>struts2</filter-name>
<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
注意:default.jsp代表一个默认首页;
注意:/*代表过滤所有;
注意:struts2的入口是一个过滤器,所以可以把struts2当过滤器来配置;
4.然后配置src/struts.xml
<!-- 第1步:先定义一个包 -->
<package name="mypck001" extends="struts-default">
<!-- myNewsAction用于spring注入 -->
<action name="NewsAction_*" class="myNewsAction" method="{1}">
<result name="success">/WEB-INF/jsp/index.jsp</result>
<result name="deleteOK">/WEB-INF/jsp/ok.jsp</result>
<result name="deleteFailed">/WEB-INF/jsp/error_delete.jsp</result>
</action>
</package>
注意:NewsAction_*代表所有以NewsAction_开头的地址;
注意:{1}代表方法名跟NewsAction_*中*的值一样;
5.然后创建4个jsp文件:default.jsp、Index.jsp、ok.jsp、error.jsp
default.jsp文件放在WEBContext目录下,很方便的跳转运行项目;
<%@ page language=”java” contentType=”text/html; charset=UTF-8″
pageEncoding=”UTF-8″%>
<!DOCTYPE html PUBLIC “-//W3C//DTD HTML 4.01 Transitional//EN” “http://www.w3.org/TR/html4/loose.dtd”>
<html>
<head>
<meta http-equiv=”Content-Type” content=”text/html; charset=UTF-8″>
<title>Insert title here</title>
</head>
<body>
<% response.sendRedirect(“myNews2Action_getMyNewsAll.action”); %>
</body>
</html>
其他三个,为了防止用户直接访问JSP页面把它们放在WEB-INF下;
6.然后再src目录myNews2.action包下创建MyNews2Action.action;
四、配置spring框架:
1.添加spring jar包;
注意:spring框架需要通过struts2-spring-plugin-2.3.30 jar 以struts插件的形式连接struts;
2.然后配置web.xml
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
注意:spring以监听器的形式监听所有实例的创建;
注意:applicationcontext.xml是spring的配置文件,因为它的默认查找路径在WEB—INF/classses下,而我们要把它放到src下就在这配置一下;
3.然后在src目录下创建jdbc.properties文件,目的是希望防止不该碰applicationContext.xml文件的人碰它;
jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/news
jdbc.user=root
jdbc.password=123456
4.然后配置applicationContext.xml:
<context:component-scan base-package="myNews2" />
注意:它是spring注解解析器,用注解可以各种<Bean>的创建;
<context:property-placeholder location="classpath:jdbc.properties" />
!引入jdbc.properties;
5.然后对各个类进行IOC的注入:
@Repository
@Scope("prototype")
public class MyNewsDaoImpl implements MyNewsDao { @Resource
private SessionFactory sf;
注意:@Repository代表这个类的实例交给spring来管理;
@Controller
@Scope("prototype")
public class MyNews2Action extends ActionSupport{ @Resource
private MyNewsService ms;
注意:@Scope(“prototype”)代表这个类的作用范围;
@Service
@Scope("prototype")
public class MyNews2ServiceImpl implements MyNewsService { @Resource
private MyNewsDao mn;
注意:模型层用@Service,控制层用@Controller,数据层用@Repository;
注意:@Resource是JDK 解析器;spring的是@Autowired和Qualifier;
五、配置Hibernate框架:
1.添加Hibernate jar包;
2.配置applicationContext.xml文件:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"

xmlns:jee="http://www.springframework.org/schema/jee" xmlns:tx="http://www.springframework.org/schema/tx"
xsi:schemaLocation="

class="org.springframework.orm.hibernate5.LocalSessionFactoryBean"
scope="prototype">
<property name="dataSource" ref="dataSource"></property> <property name="hibernateProperties">

<prop key="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</prop>
<prop key="hibernate.show_sql">true</prop>
<prop key="hibernate.format_sql">true</prop>
<!-- 禁用自动提交,保护事务的完整性 -->
<prop key="hibernate.connection.autocommit">false</prop>
<!-- 开机自动生成表 -->
<prop key="hibernate.hbm2ddl.auto">update</prop>
</props>
</property>
<property name="mappingResources">

<value>News.hbm.xml</value>
</list>
</property>
</bean> <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" >
<property name="driverClass" value="${jdbc.driver}" />
<property name="jdbcUrl" value="${jdbc.url}" />
<property name="user" value="${jdbc.user}" />
<property name="password" value="${jdbc.password}" />
<!-- 每300秒检查所有连接池中的空闲连接 -->
<property name="idleConnectionTestPeriod" value="300"></property>
<!-- 最大空闲时间,900秒内未使用则连接被丢弃。若为0则永不丢弃 -->
<property name="maxIdleTime" value="900"></property>
<!-- 最大连接数 -->
<property name="maxPoolSize" value="2"></property>
</bean></beans>
3.配置News.hbm.xml文件:
<?xml version="1.0" encoding="UTF-8"?>
<hibernate-mapping xmlns="http://www.hibernate.org/xsd/hibernate-mapping">
<class name="myNews2.entity.News" table="news">
<id name="id" column="id">
<generator class="native"/>
</id>
<!-- 属性对应字段 -->
<property name="title" type="string" length="50" column="title" not-null="true"></property>
<property name="content" type="text" length="50000" column="content" not-null="true"></property>
<property name="begintime" type="date" column="begintime" not-null="true"></property>
<property name="username" type="string" length="20" column="username" not-null="true"></property>
</class>
</hibernate-mapping>
