SpringBoot+activiti 6.0io.FileNotFoundException: class path resource [processes/] cannot be exist

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'actModelController': 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$JpaConfiguration.class]: Unsatisfied dependency expressed through method 'repositoryServiceBean' parameter 0; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'processEngine' defined in class path resource [org/activiti/spring/boot/JpaProcessEngineAutoConfiguration$JpaConfiguration.class]: Unsatisfied dependency expressed through method 'processEngine' parameter 0; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'springProcessEngineConfiguration' defined in class path resource [org/activiti/spring/boot/JpaProcessEngineAutoConfiguration$JpaConfiguration.class]: 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

解决方式

第一步：

1. 如果是单模块的项目，需要在resources目录下新建一个空的文件夹 【processes】

2. 如果是多模块的项目需要将 【processes】添加到启动项目的 resources 下。

第二步：

在配置文件yml 或者 properties 中添加如下配置

# 解决启动报错：class path resource [processes/] cannot be resolved to URL because it does not exist
  activiti:
    check-process-definitions: false
    # 检测身份信息表是否存在
    db-identity-used: false

第三步：

在springboot的启动类中添加如下配置，排除SecurityAutoConfiguration这个类

@SpringBootApplication(exclude = {
      DataSourceAutoConfiguration.class, SecurityAutoConfiguration.class })

第四步：

在yml或者properties中的数据配置的url中添加
&nullCatalogMeansCurrent=true

url: jdbc:mysql://localhost:3306/xxx?useUnicode=true&characterEncoding=utf8&zeroDateTimeBehavior=convertToNull&useSSL=true&serverTimezone=GMT%2B8&nullCatalogMeansCurrent=true

第五步：

解决javax.persistence 类冲突的方式
