springboot项目集成activiti7

Question

springboot项目整合activiti7后报错，但数据库的表可以生成，求各位看看
尝试过降版本和改配置文件，都不可以
使用的springboot版本是2.7.15，activiti版本是7.1.0

检查 Activiti Starter：确保为 Spring Boot 使用正确的 Activiti Starter。pom.xml你的或文件中应该有类似于以下内容的依赖项build.gradle

<dependency>
    <groupId>org.activiti</groupId>
    <artifactId>activiti-spring-boot-starter</artifactId>
    <version>7.1.0.M6</version>
</dependency>
