报错信息:
Description:
The bean 'beanNameViewResolver', defined in class path resource [cn/afterturn/easypoi/configuration/EasyPoiAutoConfiguration.class], could not be registered. A bean with that name has already been defined in class path resource [org/springframework/boot/autoconfigure/web/servlet/error/ErrorMvcAutoConfiguration$Whitela belErrorViewConfiguration.class] and overriding is disabled.
Action:
Consider renaming one of the beans or enabling overriding by setting spring.main.allow- bean-definition-overriding=true Disconnected from the target VM, transport: 'socket' Process finished with exit code 0
大致内容:
在类路径资源[cn / afterturn / easypoi / configuration / EasyPoiAutoConfiguration.class]中定义的bean“beanNameViewResolver”无法注册。 具有该名称的bean已在类路径资源[org / springframework / boot / autoconfigure / web / servlet / error / ErrorMvcAutoConfiguration $ WhitelabelErrorViewConfiguration.class]中定义,并且已禁用覆盖。
解决方案:
考虑通过设置spring.main.allow-bean-definition-overriding = true来重命名其中一个bean或启用覆盖,在spring boot项目的配置文件中添加下面这句话就可以了
application.yml
spring: main: allow-bean-definition-overriding: true
application.properties
spring.main.allow-bean-definition-overriding = true
