springcloud 集成 activiti 工作流 报错调试（二）

springcloud 集成 activiti 工作流 报错调试（二）

1. 项目开始启动后，就开始各种报错了。
2. 报错一：[processes/] 不存在
   解决方式：
   spring配置文件添加：spring.activiti.check-process-definitions=false
3. 报错二：Activiti6 use spring-boot-starter-web meet requestMappingHandlerMapping error
   解决方式：
   启动类上添加：

@SpringBootApplication(exclude = SecurityAutoConfiguration.class)

4. 报错三：java.sql.SQLException: The server time zone value 'Öйú±ê׼ʱ¼ä' is unrecognized or represents more than one time zone.
   解决方式：

mysql数据库连接url后添加参数：serverTimezone=GMT%2B8 

5. 报错四：mysql-connector-mysql 8.0 (spring-boot-starter-parent 管理的版本) + Activiti 6.x 自动建表失败
   解决方式：

mysql数据库连接url后添加参数：nullCatalogMeansCurrent=true 

6. 报错五：

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'actIdGroupController': Unsatisfied dependency expressed through field 'identityService'; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'identityServiceBean' defined in class path resource [org/activiti/spring/boot/DataSourceProcessEngineAutoConfiguration$DataSourceProcessEngineConfiguration.class]: Unsatisfied dependency expressed through method 'identityServiceBean' 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 com.baomidou.dynamic.datasource.exception.CannotFindDataSourceException: dynamic-datasource can not find primary datasource

解决方式：检查mysql-connector-java jar包依赖，同时检查 yml中配置的seata中的group是否修改为项目名了。
好了，本文就讲到这，下章继续报错调试。
