导入activiti相应的jar包 使用用maven，在pox.xml中配置
<dependency> <groupId>org.activiti</groupId> <artifactId>activiti-engine</artifactId> <version>5.21.0</version> </dependency> <dependency> <groupId>org.activiti</groupId> <artifactId>activiti-spring</artifactId> <version>5.21.0</version> </dependency> <dependency> <groupId>org.activiti</groupId> <artifactId>activiti-rest</artifactId> <version>5.21.0</version> </dependency>在spring.xml中配置
<!-- Activiti配置 Start --> <!-- 单例json对象 --> <bean id="objectMapper" class="com.fasterxml.jackson.databind.ObjectMapper"/> <!-- 自定义用户模块 --> <bean id="customUserEntityManager" class="cn.com.agree.aweb.springmvc.activiti.CustomUserEntityManager"> </bean> <bean id="customGroupEntityManager" class="cn.com.agree.aweb.springmvc.activiti.CustomGroupEntityManager"> </bean> <!-- Activiti引擎配置 --> <bean id="processEngineConfiguration" class="org.activiti.spring.SpringProcessEngineConfiguration"> <property name="processEngineName" value="spring"></property> <property name="dataSource" ref="jndiDataSource" /> <property name="transactionManager" ref="transactionManager" /> <property name="databaseSchemaUpdate" value="true" /> <property name="jobExecutorActivate" value="false" /> <!-- web服务重启时自动部署流程文件，自动部署引擎数据库中不存在或修改过的流程定义 --> <!-- <property name="deploymentResources"> <list> <value>bpmn/*.bpmn</value> </list> </property> --> <!-- 自定义用户模块 --> <property name="customSessionFactories"> <list> <bean class="cn.com.agree.aweb.springmvc.activiti.CustomUserEntityManagerFactory"></bean> <bean class="cn.com.agree.aweb.springmvc.activiti.CustomGroupEntityManagerFactory"></bean> </list> </property> </bean> <!-- Activiti引擎工厂 --> <bean id="processEngine" class="org.activiti.spring.ProcessEngineFactoryBean"> <property name="processEngineConfiguration" ref="processEngineConfiguration" /> </bean> <!-- Activiti的7个Service --> <bean id="repositoryService" factory-bean="processEngine" factory-method="getRepositoryService" /> <bean id="runtimeService" factory-bean="processEngine" factory-method="getRuntimeService" /> <bean id="formService" factory-bean="processEngine" factory-method="getFormService" /> <bean id="identityService" factory-bean="processEngine" factory-method="getIdentityService" /> <bean id="taskService" factory-bean="processEngine" factory-method="getTaskService" /> <bean id="historyService" factory-bean="processEngine" factory-method="getHistoryService" /> <bean id="managementService" factory-bean="processEngine" factory-method="getManagementService" /> <!-- 集成REST服务需要的bean --> <bean id="restResponseFactory" class="org.activiti.rest.service.api.RestResponseFactory" /> <bean id="contentTypeResolver" class="org.activiti.rest.common.application.DefaultContentTypeResolver" /> <!-- Activiti配置 End -->使用7个service，实现工作流的全部操作。 数据源使用项目已配置的数据源。 自定义用户模块（使用项目中的用户管理模块，放弃使用activiti的用户表），重写相应的类，对应配置中customSessionFactories的属性值，示例用户自定义如下：
package cn.com.agree.aweb.springmvc.activiti; import org.activiti.engine.impl.interceptor.Session; import org.activiti.engine.impl.interceptor.SessionFactory; import org.activiti.engine.impl.persistence.entity.UserIdentityManager; import org.springframework.beans.factory.annotation.Autowired; /** * @Description: 自定义用户 * @author chenrui chenrui@agree.com.cn * @date 2016年8月2日 * */ public class CustomUserEntityManagerFactory implements SessionFactory{ @Autowired private CustomUserEntityManager customUserEntityManager; @Override public Class<?> getSessionType() { return UserIdentityManager.class; } @Override public Session openSession() { return customUserEntityManager; } }该类继承UserEntityManager，重写对应方法
