activiti与spring集成（maven）

在pom.xml中添加以下依赖：

[java] view plaincopy

1. <dependency>  
2.     <groupId>org.activiti</groupId>  
3.     <artifactId>activiti-engine</artifactId>  
4.     <version>${activiti.version}</version>  
5. </dependency>  
6.   
7. <dependency>  
8.     <groupId>org.activiti</groupId>  
9.     <artifactId>activiti-spring</artifactId>  
10.     <version>${activiti.version}</version>  
11. </dependency>  

        此处忽略了spring的依赖，请自行配置。

        在src下添加spring-activiti.xml文件，内容如下：

[java] view plaincopy

        注意：

        1. 不要使用default-autowire="byName"，否则会报空指针异常；

        2. dataSource、transactionManager、jpaEntityManagerFactory请自行配置；

        3. ${jpa.datasource.name}为配置文件中的项，请查询资料自行配置；

        4. deploymentResources配置的是流程文件所在位置，本文中为src的diagrams目录下的所有。
