Error:
Error starting ApplicationContext. To display the conditions report re-run your application with 'debug' enabled.
2021-06-28 14:27:13.827 ERROR 7512 --- [ restartedMain] o.s.boot.SpringApplication : Application run failed
Background
It’s time to review. The teacher asked me to write a springboot project, but I couldn’t run it. Running application shows that application cannot be run
some errors were encountered in the process. I searched Baidu, and the result is as follows:
in the annotation of application, there is @ springbootapplication , which should be replaced by @ springbootapplication (exclude = datasourceautoconfiguration. Class) , but the result still doesn’t work.
Exclude to exclude such autoconfig, that is, to prohibit springboot from automatically injecting data source configuration. In this case, the automatic injection of mybits is excluded. As a result, there is a problem in the mapper layer.
Let the teacher have a look today. There is something wrong with the YML file.
Forget to write spring keywords, which I don’t understand.
server:
port: 5050 # tomcat port
servlet:
context-path: /UserModel
spring:# I forgot to write it here, so that datesource belongs to the server
datasource:
type: com.alibaba.druid.pool.DruidDataSource
driver-class-name: com.mysql.cj.jdbc.Driver
url: jdbc:mysql://localhost:3306/1202?useSSL=false&serverTimezone=Asia/Shanghai&characterEncoding=utf-8
username: root
password: root
An error occurred while accessing the controller
The error reported is the same as this:
would dispatch back to the current handler URL [/UserModel/queryUserById]
The difference between @Controller and @RestController is actually confusing
@Controller, @RestController?
Forgot the difference between get and post
Written by.
