springboot项目引入工作流activiti启动报错

解决方式：

2.0的start中默认也有一个spring-boot-autoconfigure-2.0..RELEASE.jar，如果你还引用了activiti的activiti-spring-boot-starter-rest-api.jar包，需要将两个包中的 SecurityAutoConfiguration.class 都排除，

@SpringBootApplication(exclude={
  org.activiti.spring.boot.SecurityAutoConfiguration.class,
  SecurityAutoConfiguration.class
})
