可以在分页插件PageHelperAutoConfiguration注入的时候，注入日志打印插件

public void afterPropertiesSet() {PageInterceptor interceptor = new PageInterceptor(this.helperProperties);interceptor.setProperties(this.helperProperties.getProperties());for (SqlSessionFactory sqlSessionFactory : sqlSessionFactoryList) {org.apache.ibatis.session.Configuration configuration = sqlSessionFactory.getConfiguration();if (!containsInterceptor(configuration, interceptor)) {logger.warn("加载分页插件");configuration.addInterceptor(interceptor);}//日志插件configuration.addInterceptor(new SqlLoggingInterceptor());}
}
