主要错误原因在这里：

Error creating bean with name 'activitiModelServer': Unsatisfied dependency expressed through field 'repositoryService'; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'repositoryServiceBean' defined in class path resource [org/activiti/spring/boot/JpaProcessEngineAutoConfiguration$JpaConfiguration.class]: Unsatisfied dependency expressed through method 'repositoryServiceBean' 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.NullPointerException

问题解决：

大致查了一下。我这里的问题是 act_ge_property 这张表没有数据。

于是从其他地方拷贝了数据过来。 

INSERT INTO `act_ge_property` (`NAME_`, `VALUE_`, `REV_`) VALUES ('next.dbid', '15152501', '6062');
INSERT INTO `act_ge_property` (`NAME_`, `VALUE_`, `REV_`) VALUES ('schema.history', 'create(5.17.0.2)', '1');
INSERT INTO `act_ge_property` (`NAME_`, `VALUE_`, `REV_`) VALUES ('schema.version', '5.17.0.2', '1');

Error crea ting bea n with name ‘ process Engine ‘: Factory Bea n threw exception on object creation；错误解决
spring 注入不小心就会出现这种问题。 2.我在某个service的实现类中 给方法加了个@Async（异步）注解就包错了 Error crea ting bea n with name “****” 3.从这张图可以推算应该是这三个类循环了，但其实不是 他包错的原因是 一个高手写的好代码，他竟然自己注入自己。在没有异步方法的时候运气好没有包错 添加了异步方法就包依赖循环错误了。
