No.1
启动报错
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;
解决办法:启动类上加上 @SpringBootApplication(exclude = SecurityAutoConfiguration.class)即可;因为activiti-spring-boot-starter-basic中引用了spring-boot-starter-security(具体没研究)。
No.2
启动报错
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下没有找到processes文件夹;
解决办法:在resource目录下添加processes文件夹,并且文件夹不能为空 或是在application.yml文件中加上如下配置(注意是spring节点下)
activiti:
database-schema-update: true
# 自动部署验证设置:true-开启(默认)、false-关闭
check-process-definitions: false
;
No.3
启动报错
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.
解决办法:配置数据源时url前加上jdbc-;如:jdbc-url: jdbc:mysql://localhost:3306/activity?serverTimezone=UTC&useUnicode=true&characterEncoding=utf-8
