java传统框架ssh---struts、spring、hibernate框架的搭建

2017-04-02 23:40 525 查看

本文是对ssh框架的搭建的的整理。主要是整体框架的实现，具体细节概不细究。

各版本说明：struts：2.3.1.2

hibernate：3.6.1

spring：3.2

在这里，struts担当web层的一个Controller的角色，hibernate用于dao即持久层的实现。spring用于担当大管家的角色，用于实现bean的创建，以及依赖注入。

第一部分（xml方式的实现）

一、导入jar包

1、导入struts的jar包

以及用于和spring整合的插件： struts2-spring-plugin-2.3.15.3.jar

2、hibernate的jar包

以及slf4j-log4j12-1.7.2.jar日志整合jar包、c3p0连接池、数据库驱动包这里mysql。

3、导入spring的jar包

核心jar包

aop包：

以及和struts整合的jar包

说明：orm整合hibernate、test整合junit测试、tx，jdbc数据库的事物、web整合web服务

二、相关xml文件配置

1、web.xml文件的配置

<?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">
<display-name>day37_spring03</display-name>
<!-- 配置监听器 -->
<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>

<!-- 配置前端控制器 -->
<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>
<welcome-file-list>
<welcome-file>index.html</welcome-file>
<welcome-file>index.htm</welcome-file>
<welcome-file>index.jsp</welcome-file>
<welcome-file>default.html</welcome-file>
<welcome-file>default.htm</welcome-file>
<welcome-file>default.jsp</welcome-file>
</welcome-file-list>
</web-app>

2、applicationContext.xml的配置

<?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:tx="http://www.springframework.org/schema/tx" xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation=" http://www.springframework.org/schema/beans http:
dc83
//www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">
<context:annotation-config />
<context:component-scan base-package="cn.itcast.day37_spring03"></context:component-scan>

<context:property-placeholder location="classpath:jdbc.properties"/>
<!-- 配置spring默认的连接池 -->
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
<!-- 注入连接池的属性 -->
<property name="driverClass" value="${jdbc.driverClass}" />
<property name="jdbcUrl" value="${jdbc.url}" />
<property name="user" value="${jdbc.username}" />
<property name="password" value="${jdbc.password}" />
</bean>

<!-- 配置hibernate.cfg.xml -自动生成sessionFactory -->
<!-- <bean id="" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="configLocation" value="classpath:hibernate.cfg.xml"></property>
</bean> -->

<!-- 配置hibernate.cfg.xml文件的其他属性。 -->
<bean id="sessionFactory"
class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="dataSource" ref="dataSource"></property>
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</prop>
<prop key="hibernate.hbm2ddl.auto">update</prop>
<prop key="hibernate.show_sql">true</prop>
<prop key="hibernate.format_sql">true</prop>
</props>
</property>
<property name="mappingResources">
<list>
<value>cn/keyi/day37_spring03/domain/Customer.hbm.xml</value>
</list>
</property>
</bean>

<!-- 配置事务管理器 -->
<bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory"></property> </bean>

<!-- 定义一个加强 -->
<tx:advice id="myadvice" transaction-manager="transactionManager">
<tx:attributes>
<tx:method name="add*" />
<tx:method name="find*" read-only="true"/>
</tx:attributes>
</tx:advice>

<!-- 配置一个切面： -->
<aop:config> <aop:pointcut expression="bean(userService)" id="servicePointcut" 	/>
<aop:advisor advice-ref="myadvice" pointcut-ref="servicePointcut" />
</aop:config>

<!-- 将连接池注入到dao层中 -->
<bean id="customerDao" class="cn.keyi.spring03.dao.impl.CustomerDaoImpl">
<property name="sessionFactory" ref="sessionFactory"></property>
</bean>
<bean id="customerService" class="cn.keyi.spring03.service.impl.CustomerServiceImpl">
<property name="customerDao" ref="customerDao"></property>
</bean>
<bean id="customerAction" class="cn.keyi.spring03.action.CustomerAction" scope="prototype">
<property name="customerService" ref="customerService"></property>
</bean>
</beans>

3、struts.xml的配置

<?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="ssh" namespace="/" extends="struts-default">
<action name="customerAction_*" class="customerAction" method="{1}">
<result name="add" type="redirect">/index.jsp</result>
<result name="findAll">/list.jsp</result>
</action>
</package>

</struts>

4、jdbc.properties数据库连接数据

jdbc.driverClass=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql:///spring
jdbc.username=user
jdbc.password=user

5、hibernate映射文件实例

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">
<hibernate-mapping>
<class name="cn.keyi.spring03.domain.Customer" table="customers">
<id name="id">
<generator class="native"></generator>
</id>
<property name="name"/>
<property name="sex"/>
</class>
</hibernate-mapping>

第二部分：注解方式的实现ssh框架

1、导入jar包的相关说明

Ssh相关Jar

Struts2 注解开发必须导入 struts2-conversion.jar struts/lib126 jar / 项目需要ajax json序列化导入struts2-json-plugin.jar

Hibernate 注解开发/xml开发 jar一致!

Spring 注解开发和xml开发一致!

2、注解说明

struts所用到的注解主要有：@Action @Namespace @ParentPackage @Result @Results @Actions

//需要注意的是：struts注解的使用的类的包名，必须含有：struts、struts2、action、actions约定单词。

spring主要用到的注解：这里主要用到：@Controller @Service @Repository @Transactional 等注解。

Hibernate主要用到的是实体类的注解：

@Entity：class的name属性

@Table：class的table属性

@Id：相当于id标签

@GeneratedValue(strategy=GenerationType=”AUTO”)：主键生成策略，不写默认是native

@Colume(name=””)：属性表中的字段。

@Transient：忽略该字段。

3、相关的配置文件：

web.xml的配置和前述一致。

applicationContext.xml

<?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:tx="http://www.springframework.org/schema/tx" xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">
<context:annotation-config />
<context:component-scan base-package="cn.itcast.ssh.storemanager"></context:component-scan>

<context:property-placeholder location="classpath:jdbc.properties"/>

<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">

<property name="driverClass" value="${jdbc.driverClass}" />
<property name="jdbcUrl" value="${jdbc.url}" />
<property name="user" value="${jdbc.username}" />
<property name="password" value="${jdbc.password}" />
</bean>


<bean id="sessionFactory"
class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
<property name="dataSource" ref="dataSource"></property>
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</prop>
<prop key="hibernate.hbm2ddl.auto">update</prop>
<prop key="hibernate.show_sql">true</prop>
<prop key="hibernate.format_sql">true</prop>
</props>
</property>
<property name="packagesToScan">
<list>
<value>cn.keyi.ssh.storemanager.domain</value>
</list>
</property>
</bean>

<bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory"></property>
</bean>
<tx:annotation-driven transaction-manager="transactionManager"/>

</beans>

jdbc.properties、struts.xml的配置等和前述没有多大区别，视情况而定。
至此，ssh框架的基本架构都已经完成。

最后：ssh框架的maven工程的实例pom文件：
