在这里插入图片描述

新建categorycontroller类

@RestController
@RequestMapping("/category")
public class CategoryController {@Autowiredprivate CategoryService categoryService;@PostMappingpublic Result add(@RequestBody @Validated Category category){categoryService.add(category);return Result.success("添加文章成功");}
}

然后建立service接口和serviceimpl实现类

package com.itheima.service;import com.itheima.pojo.Category;public interface CategoryService {//新增分类void add(Category category);
}

@Servicepublic class CategoryServiceImpl implements CategoryService {@Autowiredprivate CategoryMapper categoryMapper;@Overridepublic void add(Category category) {//补充属性值category.setCreateTime(LocalDateTime.now());category.setUpdateTime(LocalDateTime.now());Map<String,Object> map = ThreadLocalUtil.get();Integer userId=(Integer) map.get("id");category.setCreateUser(userId);categoryMapper.add(category);}
}

然后新增mapper接口

@Mapper
public interface CategoryMapper {//新增@Insert("insert into category(category_name,category_alias,create_user,create_time,update_time) " +"values(#{categoryName},#{categoryAlias},#{createUser},#{createTime},#{updateTime})")void add(Category category);
}
