测试环境
Windows
STS
Mysql5
Jdk1.8
Tomcat8
Maven3
Struts2 + Spring4 + Hibernate3 + Activiti5.17
一、整合Spring与Hibernate3
配置DataSource
application-config.xml内容：
<!-- 加载数据库配置文件 -->
<context:property-placeholder location="classpath:db.properties"/>
<!-- 配置数据源c3p0的方式 -->
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close">
<!-- =========== 数据库连接信息 =========== -->
<property name="driverClass" value="${driverClass}"/>
<property name="jdbcUrl" value="${jdbcUrl}"/>
<property name="user" value="${user}"/>
<property name="password" value="${password}"/>
<!-- =========== 连接池的管理配置 =========== -->
<!--初始化时获取三个连接，取值应在minPoolSize与maxPoolSize之间。Default: 3 -->
<property name="initialPoolSize" value="3"></property>
<!--连接池中保留的最小连接数。Default: 3 -->
<property name="minPoolSize" value="3"></property>
<!--连接池中保留的最大连接数。Default: 15 -->
<property name="maxPoolSize" value="5"></property>
<!--当连接池中的连接耗尽的时候c3p0一次同时获取的连接数。Default: 3 -->
<property name="acquireIncrement" value="3"></property>
<!-- 控制数据源内加载的PreparedStatements数量。如果maxStatements与maxStatementsPerConnection均为0，则缓存被关闭。Default: 0 -->
<property name="maxStatements" value="8"></property>
<!--maxStatementsPerConnection定义了连接池内单个连接所拥有的最大缓存statements数。Default: 0 -->
<property name="maxStatementsPerConnection" value="5"></property>
<!--最大空闲时间,1800秒内未使用则连接被丢弃。若为0则永不丢弃。Default: 0 -->
<property name="maxIdleTime" value="1800"></property>
</bean>
db.properties配置文件的内容
driverClass=com.mysql.jdbc.Driver
jdbcUrl=jdbc:mysql://localhost:3306/activiti?autoReconnect=true
user=root
password=root
配置hibernate3的SessionFactory
<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<!-- 注入dataSource -->
<property name="dataSource" ref="dataSource"/>
<!-- 引入hibernate.cfg.xml， 指定hibernate的配置文件的位置 -->
<property name="configLocation" value="classpath:hibernate.cfg.xml"/>
</bean>
测试SessionFactory
// 测试SessionFactory
@Test
public void testSessionFactory() throws Exception {
SessionFactory sessionFactory = (SessionFactory) ctx.getBean("sessionFactory");
Assert.assertNotNull(sessionFactory.openSession());
ctx.destroy();
}
配置声明式事务管理（使用基于注解的方式）
<!-- 开启基于注解的事务管理 -->
<tx:annotation-driven transaction-manager="transactionManager"/>
<!-- 设置hibernate3的事务管理 -->
<bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory"/>
</bean>
在web.xml中配置OpenSessionInView
Spring 的 OpenSessionInView 过滤器（解决抛LazyInitializationException异常的问题）
<!-- 配置 spring 的 OpenSessionInView 过滤器 -->
<filter>
<filter-name>OpenSessionInView</filter-name>
<filter-class>org.springframework.orm.hibernate3.support.OpenSessionInViewFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>OpenSessionInView</filter-name>
<url-pattern>*.do</url-pattern>
</filter-mapping>
LazyInitializationException异常说明
1，对于集合属性，默认是lazy=”true”的，在第一次使用时才加载。
2，但在加载时，如果Session已经关掉了就会抛LazyInitializationException异常
二、整合 Spring 与 Struts2
在web.xml中配置
<!-- 配置Spring的用于初始化ApplicationContext对象的监听器 -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:application-config.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<!-- 配置Struts2的核心的过滤器 -->
<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>
在struts.xml中配置Action
<struts>
<constant name="struts.action.extension" value="do"></constant>
<package name="dengfengdecao" namespace="/" extends="struts-default">
<action name="user_*" class="userAction" method="{1}">
<result name="success">/index.jsp</result>
</action>
</package>
</struts>
引入struts2-spring-plugin-2.3.20.jar插件
当引入这个插件后，原先所struts创建的action类，交给了spring创建。在struts2-spring-plugin.jar中有一个struts-plugin.xml，里面声明了action类由spring工厂创建。
这个插件重写了struts的对象工厂，当创建一个action类时，它会根据struts的配置文件的class属性的值与spring配置文件中的id属性的值相匹配。如果没有与之想匹配，将会像没有使用这个插件前一样创建，然后由spring自动装配。
说明：
1，在写Action时要指定 @Controller 与 @Scope(“prototype”)；
2，在struts.xml中配置action时，在class属性中写bean的名称。
部署到Tomcat中并访问测试
在pom.xml中添加一下内容
<!-- 设置虚拟路径，并自动启动tomcat -->
<build>
<!-- 如果发布到根目录则改为ROOT -->
<finalName>activiti-ssh</finalName>
<plugins>
<plugin>
<!-- org.codehaus.cargo插件依赖 -->
<groupId>org.codehaus.cargo</groupId>
<artifactId>cargo-maven2-plugin</artifactId>
<version>1.4.15</version>
<configuration>
<container>
<containerId>tomcat8x</containerId>
<home>D:/Dev/Tomcat8</home>
</container>
<configuration>
<type>existing</type>
<home>D:/Dev/Tomcat8</home>
</configuration>
</configuration>
<executions>
<execution>
<id>cargo-run</id>
<phase>install</phase>
<goals>
<goal>run</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
</build>
在~/.m2/setting.xml 中添加org.codehaus.cargo插件支持
<pluginGroup>org.codehaus.cargo</pluginGroup>
右键pom.xml 》maven install 启动tomcat后，在地址栏输入
http://localhost:8080/activiti-ssh 即可访问首页。
三、整合Spring与Activiti5
在activiti-context.xml中配置
<!-- 配置activiti引擎 -->
<bean id="processEngineConfiguration" class="org.activiti.spring.SpringProcessEngineConfiguration">
<property name="dataSource" ref="dataSource" />
<property name="transactionManager" ref="transactionManager" />
<property name="databaseSchemaUpdate" value="true" />
<property name="jobExecutorActivate" value="false" />
</bean>
<!-- 加载activiti引擎 -->
<bean id="processEngine" class="org.activiti.spring.ProcessEngineFactoryBean">
<property name="processEngineConfiguration" ref="processEngineConfiguration" />
</bean>
<!-- activiti的各种服务接口 -->
<bean id="repositoryService" factory-bean="processEngine" factory-method="getRepositoryService" />
<bean id="runtimeService" factory-bean="processEngine" factory-method="getRuntimeService" />
<bean id="taskService" factory-bean="processEngine" factory-method="getTaskService" />
<bean id="formService" factory-bean="processEngine" factory-method="getFormService" />
<bean id="historyService" factory-bean="processEngine" factory-method="getHistoryService" />
<bean id="managementService" factory-bean="processEngine" factory-method="getManagementService" />
<bean id="identityService" factory-bean="processEngine" factory-method="getIdentityService" />
在application-config.xml中配置
<!-- 引入activiti的配置文件 -->
<import resource="activiti-context.xml"/>
测试
// 测试ProcessEngine
@Test
public void testProcessEngine() {
ProcessEngine processEngine = (ProcessEngine) ac.getBean("processEngine");
Assert.assertNotNull(processEngine);
}
