解决方案

自定义一个Configuration类，实现ProcessEngineConfigurationConfigurer类，重写configure方法，设置数据库类型为Oracle，代码如下:

package cn.xxx.configuration;  import org.activiti.spring.SpringProcessEngineConfiguration; import org.activiti.spring.boot.ProcessEngineConfigurationConfigurer; import org.springframework.context.annotation.Configuration;  @Configuration public class MyActivitiConfig implements ProcessEngineConfigurationConfigurer {      @Override     public void configure(SpringProcessEngineConfiguration springProcessEngineConfiguration) {         springProcessEngineConfiguration.setDatabaseType("oracle");     } }
