版本信息：
Activiti：6.0.0
tknybatis：1.1.4
spring boot：2.0.5.RELEASE
报错：
mybatis和activiti集成时不会报错，但是mapper和activiti集成到一起时启动就会报错，错误信息如上。
JpaProcessEngineAutoConfiguration部分代码：
public class JpaProcessEngineAutoConfiguration { public JpaProcessEngineAutoConfiguration() { } @Configuration @ConditionalOnClass(name = {"javax.persistence.EntityManagerFactory"}) @EnableConfigurationProperties({ActivitiProperties.class}) public static class JpaConfiguration extends AbstractProcessEngineAutoConfiguration { public JpaConfiguration() { } } }
可以看到EntityManagerFactory是被@ConditionlOnClass所注解的。而EntityManagerFactory是来自于JPA相关的接口。其实这里是Activiti所做的判断，如果项目使用了JPA，那走JPA，如果没有，则走Mybatis。所以只引入Mybatis和Activiti的话项目不会报错。继续看mapper的源码，其实mapper并没有实现EntityManagerFactory接口，而是自己写了一套，而在Activiti中则认为当前项目使用的是JPA，找不到EntityManagerFactory的实现类。
我的解决办法是引入jar：
<!--没有会引起mybaits plus通用mapper和activity的冲突--> <dependency> <groupId>org.activiti</groupId> <artifactId>activiti-spring-boot-starter-jpa</artifactId> <version>${activiti.version}</version> </dependency>
