public class SpecificationServiceImpl implements SpecificationService {
@Autowired
private SpecificationMapper specificationMapper;
@OverRide
public Specification queryById(Long id) {
return this.specificationMapper.selectByPrimaryKey(id);
}
@OverRide
public void saveSpecification(Specification specification) {
this.specificationMapper.insert(specification);

this.specificationMapper.updateByPrimaryKeySelective(specification);
}
@OverRide

例如delete这边,明明只需要根据id去删除就ok了。哪有直接传个对象进行删除的???
public void deleteSpecificationByCategoryId(Long id){ if (id == null || this.specificationMapper.selectByPrimaryKey(id) == null){ throw new LyException(ExceptionEnum.ID_DOES_NOT_EXIST); } this.specificationMapper.deleteByPrimaryKey(id); }
顺带你controller里面很多错,尽管编译器不一定会报错。然而。。你这逻辑不对十分尴尬
我见加载工程比较慢,原来是从国外下载jar包,我记得我本地maven配的是阿里的啊,原来pom.xml中有做配置,建议把pom中修改阿里的,或者删掉,用本地的
我从网上找的项目笔记不是这一个版本的。感谢
//如果pid的值为-1那么需要获取数据库中最后一条数据,(并没有发现这样能有什么意义)
if (pid == -1){
List last = this.categoryService.queryLast();
return ResponseEntity.ok(last);
}
查询数据库最后一个记录感觉没必要,问一下作者是怎么考虑的
大佬,能加个好友么,有些问题想请教你一下
跑elasticsearch服务的时候,测试类报错,请教这个zenmejiejue
缺少了两个表 tb_spec_group 和 tb_spec_param
再三检查了项目中给的SQL也没有这两个表
我用的后端页面不是你仓库中的,和这个有关系吗?
feign.FeignException: status 404 reading GoodsClient#querySpuDetailBySpuId(Long)
说吧 你是itcast多少期的吧

黑马的乐优商城代码更新了
提供的代码是您的GitHub提供的 但是和视频上提供的不一样 ,可以说出如有点大,例如gatway那块 resource文件中有zuul和ribbon的配置 ,而您提供的代码中没有啊,可不可以提供一份呢 ,网上老师这一批大概是2018年九月份讲的这个,迫切希望您可以答复 ,谢谢大神
