一个简单的SSH框架程序

1. 加入Spring 1) 加入jar包 2) 配置web.xml文件 <?xml version="1.0" encoding="UTF-8"?> <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" id="WebApp_ID" version="2.5"> <!-- 配置Spring配置文件的名称和位置 --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:applicationContext.xml</param-value> </context-param> <!-- 启动IOC容器的ServletContextListener --> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> </web-app> 3) 加入Spring的配置文件 <?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:aop="http://www.springframework.org/schema/aop" xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd"> </beans> 2. 加入Hibernate 1) 同时建立持久化类，和其对应的.hbm.xml文件，生成对应的数据表 2) Spring整合hibernate 3) 步骤： ① 加入jar包 ② 在类路径下加入hibernate.cfg.xml文件，在其中配置hibernate的基本属性 <hibernate-configuration> <session-factory> <!-- 配置hibernate的基本属性 --> <!-- 方言 --> <property name="hibernate.dialect"></property> <!-- 是否显示及格式化SQL --> <property name="hibernate.format_sql">true</property> <property name="hibernate.show_sql">true</property> <!-- 生成数据表的策略 --> <property name="hibernate.hbm2ddl.auto">update</property> <!-- 二级缓存相关 --> <!-- ... --> </session-factory> </hibernate-configuration> ③ 建立持久化类，和其对应的.hbm.xml文件 Department.hbm.xml： <hibernate-mapping> <class name="com.cf.ssh.entities.Department" table="department" schema="dbo" catalog="ssh"> <id name="id" type="java.lang.Integer"> <column name="ID" /> <generator class="native"></generator> </id> <property name="departmentName" type="java.lang.String"> <column name="DEPARTMENT_NAME" not-null="true" /> </property> <!-- 映射单向1-n的关联关系 --> <set name="employees" inverse="true"> <key> <column name="DEPT_ID" not-null="true" /> </key> <one-to-many class="com.cf.ssh.entities.Employee" /> </set> </class> </hibernate-mapping> ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Employee.hbm.xml： <hibernate-mapping> <class name="com.cf.ssh.entities.Employee" table="employee" schema="dbo" catalog="ssh"> <id name="id" type="java.lang.Integer"> <column name="ID" /> <generator class="native"></generator> </id> <!-- 映射单向n-1的关联关系 --> <many-to-one name="department" class="com.cf.ssh.entities.Department"> <column name="DEPT_ID" not-null="true" /> </many-to-one> <property name="lastName" type="java.lang.String"> <column name="LAST_NAME" not-null="true" /> </property> <property name="email" type="java.lang.String"> <column name="EMAIL" not-null="true" /> </property> <property name="birth" type="java.lang.String"> <column name="BIRTH" not-null="true" /> </property> <property name="createTime" type="java.sql.Timestamp"> <column name="CREATE_TIME" length="23" not-null="true" /> </property> </class> </hibernate-mapping> ④ 和Spring进行整合 i. 加入c3p0和sqlserver的驱动 ii. 创建db.properties user=sa password=123123 driverclass=com.microsoft.sqlserver.jdbc.SQLServerDriver jdbcurl=jdbc\:sqlserver\://127.0.0.1\:1433;databaseName\=ssh jdbc.initialPoolSize =5 jdbc.maxPoolSize =10 iii. 在Spring的配置文件中配置：数据源，SessionFactory，声明式事务 <!-- 导入资源文件db.properties --> <context:property-placeholder location="classpath:db.properties"/> <!-- 配置C3P0数据源 --> <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"> <property name="user" value="${user}"></property> <property name="password" value="${password}"></property> <property name="jdbcUrl" value="${jdbcurl}"></property> <property name="driverClass" value="${driverclass}"></property> <property name="initialPoolSize" value="${jdbc.initialPoolSize}"></property> <property name="maxPoolSize" value="${jdbc.maxPoolSize}"></property> </bean> <!-- 配置SessionFactory --> <bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean"> <!-- 配置数据源属性 --> <property name="dataSource" ref="dataSource"></property> <!-- 配置hibernate配置文件的位置及名称 --> <property name="configLocation" value="classpath:hibernate.cfg.xml"></property> <!-- 配置hibernate映射文件的位置及名称.可以使用通配符 --> <property name="mappingLocations" value="classpath:com/cf/ssh/entities/*.hbm.xml"></property> </bean> <!-- 配置Spring的声明式事务 --> <!-- 1. 配置hibernate的事务管理器 --> <bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager"> <property name="sessionFactory" ref="sessionFactory"></property> </bean> <!-- 2. 配置事务属性 --> <tx:advice id="txAdvice" transaction-manager="transactionManager"> <tx:attributes> <tx:method name="get*" read-only="true"/> <tx:method name="*"/> </tx:attributes> </tx:advice> <!-- 3. 配置事务切入点，再把事务属性和事务切入点关联起来 --> <aop:config> <aop:pointcut expression="execution(* com.cf.ssh.service.*.*(..))" id="txPointcut"/> <aop:advisor advice-ref="txAdvice" pointcut-ref="txPointcut"/> </aop:config> 3. 加入Struts2 1) 加入jar包：若有重复的jar包，则需要删除版本较低的jar包。 2) 在web.xml文件中配置Struts2的Filter <!-- 加入Struts2的Filter --> <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> 3) 加入Struts2的配置文件 <?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN" "http://struts.apache.org/dtds/struts-2.3.dtd"> <struts> <constant name="struts.enable.DynamicMethodInvocation" value="false" /> <constant name="struts.devMode" value="true" /> <package name="default" namespace="/" extends="struts-default"> </package> </struts> 4) 整合Spring ① 加入Struts2的Spring插件的jar包：struts2-spring-plugin-2.3.24.jar ② 在Spring的配置文件中正常配置Action，注意Action的scope为prototype <bean id="employeeAction" class="com.cf.ssh.actions.EmployeeAction" scope="prototype"> </bean> ③ 在Struts2的配置文件中配置Action时，class属性指向该Action在IOC中的id
