Error message:

Solution:
1. First add: &allowMultiQueries=true after the database connection string

jdbc:mysql://127.0.0.1:3306/test?useUnicode=true&characterEncoding=utf-8&useSSL=true&serverTimezone=GMT%2B8&allowMultiQueries=true

2. If there is still error, add a file

@Configuration
public class DruidConfig {   
     
     @Bean
     @ConfigurationProperties(prefix="spring.datasource")
     public DataSource druidPrimary(){
          DruidDataSource druidDataSource = new  DruidDataSource();
          List<Filter> filterList = new ArrayList<>();
          filterList.add(wallFilter());
          druidDataSource.setProxyFilters(filterList);
          return new DruidDataSource();     
     }    
     
     @Bean
    public WallFilter wallFilter(){
        WallFilter wallFilter = new WallFilter();
        wallFilter.setConfig(wallConfig());
        return wallFilter;
    }
