当前mybaits-plus版本为3.5.3
springboot启动报错Bean named ‘ddlApplicationRunner’ is expected to be of type ‘org.springframework.boot.Runner’ but was actually of type ‘org.springframework.beans.factory.support.NullBean’
解决：在启动类加上方法
public static void main(String[] args) {
SpringApplication.run(SpringbootApplication.class, args);
}
/**
* 解决：Bean named 'ddlApplicationRunner' is expected 的报错
* @param ddlList
* @return
*/
@Bean
public DdlApplicationRunner ddlApplicationRunner(@Autowired(required = false) List ddlList) {
return new DdlApplicationRunner(ddlList);
}
