The errors encountered in writing as service items today are shown below. I only know that the creation of error creating bean with name ‘servletendpointregistrar’ defined in class path resource failed. I also found some solutions on the Internet. The most common solutions are that there is a lack of JDBC dependency, or that the database configuration file is wrong. I also compared the database, There is no lack of JDBC dependency, which shows that my database and dependency are correct. I compared other service services and found that more configuration files were introduced into the configuration file

This configuration file defines the user IP and access path, as well as some configuration files related to service monitoring, management and operation and maintenance. However, the remote call is not used in the service, but I introduced this configuration file. The reason for my error is this, so I recorded it

I commented out the import file and the project started. Record it again, and I hope it will be helpful to you. Comment out the following import file
