springboot整合activiti7 启动报错。

springboot整合activiti7
出现以下问题。
不知道问题出再哪。


APPLICATION FAILED TO START


Description:

Parameter 2 of method processExtensionService in org.activiti.spring.process.autoconfigure.ProcessExtensionsAutoConfiguration required a bean of type 'com.fasterxml.jackson.databind.ObjectMapper' that could not be found.

The following candidates were found but could not be injected:
- Bean method 'objectMapper' in 'ConnectorAutoConfiguration' not loaded because @ConditionalOnMissingClass found unwanted class 'org.springframework.http.converter.json.Jackson2ObjectMapperBuilder'

Action:

Consider revisiting the entries above or defining a bean of type 'com.fasterxml.jackson.databind.ObjectMapper' in your configuration.

我这里有springboot整合activiti5的,不知是否对你有帮助。

1、查一下activiti7 支持的springboot 的版本
2、排查一下是否有依赖冲突。
3、com.fasterxml.jackson.databind.ObjectMapper 这个存不存在。
