activiti与spring集成（maven）

在pom.xml中添加以下依赖：

[java] view
plaincopy





<dependency>

<groupId>org.activiti</groupId>

<artifactId>activiti-engine</artifactId>

<version>${activiti.version}</version>

</dependency>

<dependency>

<groupId>org.activiti</groupId>

<artifactId>activiti-spring</artifactId>

<version>${activiti.version}</version>

</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。
