添加Processes目錄

SpringBoot集成activiti默認會從classpath下的processes目錄下讀取流程定義文件，所以需要在src/main/resources目錄下添加processes目錄，並在目錄中創建流程文件，添加目錄后，目錄結構變為：

 

如果沒有processes目錄，則需要修改配置spring.activiti.process-definition-location-prefix，指定流程文件存放目錄。

Spring集成Activiti6默認支持**.bpmn20.xml和**.bpmn格式的流程定義文件，修改支持的文件格式，通過配置spring.activiti.process-definition-location-suffixes修改

如：

   
   
  
  
          
 
           
 
            
 
             
 
            
 
            
 
             

               spring: 
             
 
            
 
           
 
            
 
             
 
            
 
            
 
             

               activiti: 
             
 
            
 
           
 
            
 
             
 
            
 
            
 
             

               check-process-definitions: 
              true #自動檢查、部署流程定義文件 
             
 
            
 
           
 
            
 
             
 
            
 
            
 
             

               database-schema-update: 
              true #自動更新數據庫結構 
             
 
            
 
           
 
            
 
             
 
            
 
            
 
             

               process-definition-location-prefix: classpath:/processes/ #流程定義文件存放目錄 
             
 
            
 
           
 
            
 
             
 
            
 
            
 
             

               #process-definition-location-suffixes: #流程文件格式 
             
 
            
 
           
 
            
 
             
 
            
 
            
 
             

               # - **.bpmn20.xml 
             
 
            
 
           
 
            
 
             
 
            
 
            
 
             

               # - **.bpmn 
             
 
            
 
          
  
  
 
 
         

啟動項目時，如果沒有流程部署，就不能通過自動注入，使用RuntimeService等API，依賴注入時后報錯。

ActivitiProperties中定義了activiti的自動配置項，其他配置請查看ActivitiProperties屬性。

添加數據源

添加數據源，項目中添加數據源，初始化數據庫結構，后續保存流程數據，

查看activiti-spring-boot-starter-basic-6.0.0.jar發現，org.activiti.spring.boot.SecurityAutoConfiguration編譯報錯，這時候將SecurityAutoConfiguration排除到SpringBoot啟動之外，即@SpringBootApplication注解添加exclude = SecurityAutoConfiguration.class屬性

   
   
  
  
          
 
           
 
            
 
             
 
            
 
            
 
             
 
              @SpringBootApplication(scanBasePackages = 
              "com.legao.server", exclude = SecurityAutoConfiguration.class)

              public 
              class WorkflowServer {

               SpringApplication.run(WorkflowServer.class, args); 
             
 
            
 
           
 
            
 
             
 
            
 
            
 
             

               } 
             
 
            
 
           
 
            
 
             
 
            
 
            
 
             

               } 
             
 
            
 
          
  
  
 
 
         

再啟動發現啟動正常，這時候SpringBoot集成activiti已經啟動成功，查看數據庫，Activiti6運行所需的28張表也已經創建成功。
