Error creating document instance. and byte 1 of the UTF-8 sequence of bytes is invalid

For the study of MyBatis, I encountered many inexplicable bugs from the very beginning! After going through google, it didn't solve it. Later, I changed it inexplicably. Look at the bug first:

Process finished with exit code -1

First of all, for reading bugs. In idea, you should read backwards, from bottom to top. Just look at the cause by line. For the above error, you only need to remove the Chinese comments in the interface mapping file and configuration file of mybatis, or you can change the encoding method to utf8.

About the priority of the .properties file (additional)

We knew before that we can implement the reference configuration file through the properties property: the reference configuration file code given in the official Mybatis document is:

 <!--include config file-->
   <properties resource="db.properties">
       <property name="username" value="root"/>
       <property name="pwd" value="123123"/>
   </properties>

We can also write the code to import the configuration file as:

<properties resource="db.properties"/>

The premise of this is that our resource file contains the name and pwd attributes! When we use the official method of importing configuration files but write the name and pwd attributes in the external configuration file, idea will automatically execute the code based on the external file as the standard.
