Springboot: start error reporting after introducing paging plug-in PageHelper

The main errors are as follows:

org.springframework.beans.factory.BeanCreationException: 
Error creating bean with name 'com.github.pagehelper.autoconfigure.PageHelperAutoConfiguration': 
Post-processing of merged bean definition failed; nested exception is java.lang.IllegalStateException: Failed to introspect Class [com.github.pagehelper.autoconfigure.PageHelperAutoConfiguration] from ClassLoader [sun.misc.Launcher$AppClassLoader@764c12b6]

The solution is to change the version of PageHelper to 1.2.3:1

	<dependency>
           <groupId>com.github.pagehelper</groupId>
           <artifactId>pagehelper-spring-boot-starter</artifactId>
           <version>1.2.3</version>
      </dependency>

Note: the spring boot used is version 2.1.2
