工作问题记录

一、找不到Service

org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'xxxx.service.aaaService' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {}

.....

Description:

Parameter 3 of constructor in cn.cxipcc.tccrm2.activiti.to.camunda.utils.CamundaMigrateUtil required a bean of type 'cn.cxipcc.tccrm2.activiti.to.camunda.service.ActHiDetailService' that could not be found.

Action:

Consider defining a bean of type 'cn.cxipcc.tccrm2.activiti.to.camunda.service.ActHiDetailService' in your configuration.

原因： 在service属性注入时没有找到bean

分析：ServiceImpl没有实现该Service

例如

 正确如下

 

二、关于数据库切换问题

描述：@Transactional注解不能切换数据库，当访问其他数据库时，会出现null值

解决：需要将事务注解改为@DCTransactional
