springboot集成activiti工作流時容易出現的問題
No.1
啟動報錯
org.springframework.beans.factory.BeanCreationException: Error creating bean with name ‘org.activiti.spring.boot.SecurityAutoConfiguration‘: Initialization of bean failed; nested exception is java.lang.ArrayStoreException: sun.reflect.annotation.TypeNotPresentExceptionProxy；
解決辦法：啟動類上加上 @SpringBootApplication(exclude = SecurityAutoConfiguration.class)即可；因為
No.2
啟動報錯
org.springframework.beans.factory.BeanCreationException: Error creating bean with name ‘springProcessEngineConfiguration‘ defined in class path resource [xxxxx/xxxx/xxx.java]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.activiti.spring.SpringProcessEngineConfiguration]: Factory method ‘springProcessEngineConfiguration‘ threw exception; nested exception is java.io.FileNotFoundException: class path resource [processes/] cannot be resolved to URL because it does not exist；
意思是在resource下沒有找到processes文件夾；
解決辦法：在resource目錄下添加processes文件夾，並且文件夾不能為空 或是在application.yml文件中加上如下配置（註意是spring節點下）
activiti:
database-schema-update: true
# 自動部署驗證設置:true-開啟（默認）、false-關閉
check-process-definitions: false
；
No.3
啟動報錯
org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name ‘runtimeServiceBean‘ defined in class path resource [com/example/config/ActivitiConfig.class]: Unsatisfied dependency expressed through method ‘runtimeServiceBean‘ parameter 0; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name ‘processEngine‘: FactoryBean threw exception on object creation; nested exception is java.lang.IllegalArgumentException: jdbcUrl is required with driverClassName.
解決辦法：配置數據源時url前加上jdbc-；如：jdbc-url: jdbc:mysql://localhost:3306/activity?serverTimezone=UTC&useUnicode=true&characterEncoding=utf-8
