1. 使用Eclipse创建Maven项目

2. 配置pom.xml引入需要的依赖包

<dependencies>
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>3.8.1</version>
<scope>test</scope>
</dependency> <!-- struts2 -->
<dependency>

<version>2.5.20</version>
</dependency> <!-- spring -->

</dependency> <!-- hibernate -->
<dependency>

<version>2.5.20</version>
</dependency> <!-- 数据库 -->
<dependency>

</dependency>
<!-- log4j-core -->
<dependency>
<groupId>org.apache.logging.log4j</groupId>
<artifactId>log4j-core</artifactId>
<version>2.11.2</version>
</dependency>
</dependencies>

3. 在源码路径下配置hibernate.cfg.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory>
<property name="hibernate.c3p0.max_size">10</property>
<property name="hibernate.dialect">org.hibernate.dialect.SQLServerDialect</property>
<property name="hibernate.hbm2ddl.auto">update</property>
<property name="hibernate.show_sql">true</property>
</session-factory>
</hibernate-configuration>

数据源依赖的数据可以放入spring配置中

4. 在源码路径下配置Spring配置文件 我这里为Spring.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:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:tx="http://www.springframework.org/schema/tx"
xmlns:aop="http://www.springframework.org/schema/aop"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.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 "> <context:component-scan base-package="com.hugh.ssh.dao" /> <!-- 配置数据源 -->
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
<property name="driverClassName" value="com.microsoft.sqlserver.jdbc.SQLServerDriver" />
<property name="url" value="jdbc:sqlserver://IP地址:1433;DatabaseName=pz_test;" />
<property name="username" value="sa"/>
<property name="password" value="密码"/>
</bean> <!-- 配置session工厂 -->
<bean id="sessionFactory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean" lazy-init="false">
<property name="dataSource" ref="dataSource" />
<property name="configLocation" value="classpath:hibernate.cfg.xml"></property>
<!-- //加载实体类的映射文件位置及名称 -->
<property name="mappingLocations" value="classpath:com/hugh/ssh/domain/*.hbm.xml"></property>
</bean> <!-- 配置Spring声明式事务 -->
<bean id="transactionManager" class="org.springframework.orm.hibernate5.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory"></property>
</bean> <!-- 配置事务事务属性 -->
<tx:advice id="txAdvice" transaction-manager="transactionManager">
<tx:attributes>
<tx:method name="get*" read-only="true"/>
<tx:method name="*"/>
</tx:attributes>
</tx:advice> <!-- 配置事务切点，并把切点和事务属性关联起来 -->
<aop:config>
<aop:pointcut expression="execution(* com.hugh.ssh.dao.impl.*.*(..))" id="txPointcut"/>
<aop:advisor advice-ref="txAdvice" pointcut-ref="txPointcut"/>
</aop:config></beans>

5. 在源码路径下配置struts.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.5//EN"
"http://struts.apache.org/dtds/struts-2.5.dtd"><struts> <!-- 指定由spring负责action对象的创建 -->
<constant name="struts.objectFactory" value="spring" /> <!-- 所有匹配*.action的请求都由struts2处理 -->
<constant name="struts.action.extension" value="action," />
<!-- 是否启用开发模式 -->
<constant name="struts.devMode" value="true" />
<!-- struts配置文件改动后，是否重新加载 -->
<constant name="struts.configuration.xml.reload" value="true" />
<!-- 设置浏览器是否缓存静态内容 -->
<constant name="struts.serve.static.browserCache" value="false" />
<!-- 请求参数的编码方式 -->
<constant name="struts.i18n.encoding" value="UTF-8" />
<!-- 每次HTTP请求系统都重新加载资源文件，有助于开发 -->
<constant name="struts.i18n.reload" value="true" />
<!-- 文件上传最大值 -->
<constant name="struts.multipart.maxSize" value="104857600" />
<!-- 让struts2支持动态方法调用 -->
<constant name="struts.enable.DynamicMethodInvocation" value="true" />
<!-- Action名称中是否还是用斜线 -->
<constant name="struts.enable.SlashesInActionNames" value="false" />
<!-- 允许标签中使用表达式语法 -->
<constant name="struts.tag.altSyntax" value="true" />
<!-- 对于WebLogic,Orion,OC4J此属性应该设置成true -->
<constant name="struts.dispatcher.parametersWorkaround" value="false" /> <package name="basicstruts2" extends="struts-default">
<action name="index">
<result>/index.jsp</result>
</action>
</package></struts>

6. 配置项目的web.xml

<?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" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
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" metadata-complete="true"> <display-name>ssh</display-name> <!-- 整合Spring -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:Spring.xml</param-value>
</context-param> <!-- 整合Struts2 -->
<filter>
<filter-name>struts2</filter-name>
<filter-class>org.apache.struts2.dispatcher.filter.StrutsPrepareAndExecuteFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
</web-app>

7. 源码路径下配置 log4j2.xml

<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="WARN">
<Appenders>
<Console name="Console" target="SYSTEM_OUT">
<PatternLayout pattern="%d{YYYY-MM-dd HH:mm:ss} [%t] %-5p %c{1}:%L - %msg%n" />
</Console> <RollingFile name="RollingFile" filename="log/test.log"
filepattern="${logPath}/%d{YYYYMMddHHmmss}-fargo.log">
<PatternLayout pattern="%d{YYYY-MM-dd HH:mm:ss} [%t] %-5p %c{1}:%L - %msg%n" />
<Policies>
<SizeBasedTriggeringPolicy size="10 MB" />
</Policies>
<DefaultRolloverStrategy max="20" />
</RollingFile> </Appenders>
<Loggers>
<Root level="info">
<AppenderRef ref="Console" />
<AppenderRef ref="RollingFile" />
</Root>
</Loggers>
</Configuration>

spring5不支持log4j.properties

8.   说明

  • 整合中主要是通过web.xml配置为项目设定spring的监听器进行自动装配
  • 通过web.xml配置过滤器拦截请求使用struts2作为MVC框架
  • struts2配置文件指定spring为其生成action对象，如果不指定，action中就无法自动注入
  • Spring整合hibernate主要是把hibernate的session工厂配置成bean
  • log4j.properties是spring报错时候需要用到的

整合后系统的一个运行大概是：请求先被spring进行监听，启动spring容器进行加载各种bean，然后处理完毕后通过struts2的拦截器拦截到请求，根据配置执行action得到结果返回前端，而hibernate的sessionFactory则通过spring直接注入
