Activiti + Spring开发环境搭建

Spring + Spring MVC + Activiti + MyBatis

开发环境

• Eclipse Luna (4.4.2)
• JDK 1.7.0_68
• Maven 3.3.3
• Tomcat 7.0
• Activiti 5.17.0
• 其他
  • eclipse插件: activiti designer(activiti流程设计工具)

使用maven搭建web工程

(略)

编写pom.xml

编写web.xml

    Servlet 3.0 Web Application

    
        contextConfigLocation
        classpath*:applicationContext-spring.xml
    

    
        org.springframework.web.context.ContextLoaderListener
    

    
        encodingFilter
        org.springframework.web.filter.CharacterEncodingFilter
        
            encoding
            UTF-8
        
        
            forceEncoding
            true
        
    
    
        encodingFilter
        /*
    

    
        dispatcher
        org.springframework.web.servlet.DispatcherServlet
        
            contextConfigLocation
            classpath*:spring-mvc.xml
        
        1
    
    
        dispatcher
        *.action
    

编写spring相关的配置文件

applicationContext-spring.xml

applicationContext-activiti.xml

applicationContext-mybatis.xml

spring-mvc.xml

mybatis-config.xml

db.properties

db.driver=org.h2.Driver
db.url=jdbc:h2:mem:activiti;DB_CLOSE_DELAY=1000
db.username=sa
db.password=

使用activiti designer绘制流程图

Eclipse安装activiti designer
help >> install new sofeware >> add 
name: Activiti BPMN 2.0 designer , location:  http://activiti.org/designer/update/

demo.process.test.png

  
    
    
    
    
    
    
    
    
      
        PT5S
