从这开始进入文章相关的接口开发本章主要介绍定义文章分类接口和新增文章分类 建表语句和测试用例在SpringBoot专栏首页此处只涉及后端代码。 一、后端代码
1. CategoryController
package org.example.springboot3.bigevent.controller;import org.example.springboot3.bigevent.entity.Category;
import org.example.springboot3.bigevent.entity.Result;
import org.example.springboot3.bigevent.service.CategoryService;
import org.example.springboot3.bigevent.utils.ThreadLocalUtil;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.validation.annotation.Validated;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RestController;
import java.util.Map;/*** Create by zjg on 2024/5/26*/
RestController
public class CategoryController {AutowiredCategoryService categoryService;PostMapping(/category)public Result add(RequestBody Validated Category category){MapString, Object claims ThreadLocalUtil.get();Integer userId (Integer) claims.get(userId);category.setCreateUser(userId);int i categoryService.add(category);if(i!1){return Result.error(新增文章分类失败,请稍后重试!);}return Result.success(新增文章分类成功);}
}
2. service
package org.example.springboot3.bigevent.service;import org.example.springboot3.bigevent.entity.Category;/*** Create by zjg on 2024/5/26*/
public interface CategoryService {public int add(Category category);
}
package org.example.springboot3.bigevent.service;import org.example.springboot3.bigevent.entity.Category;
import org.example.springboot3.bigevent.mapper.CategoryMapper;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import java.time.LocalDateTime;/*** Create by zjg on 2024/5/26*/
Service
public class CategoryServiceImpl implements CategoryService{AutowiredCategoryMapper categoryMapper;Overridepublic int add(Category category) {category.setCreateTime(LocalDateTime.now());category.setUpdateTime(LocalDateTime.now());return categoryMapper.insert(category);}
}
3. CategoryMapper
package org.example.springboot3.bigevent.mapper;import com.baomidou.mybatisplus.core.mapper.BaseMapper;
import org.apache.ibatis.annotations.Mapper;
import org.example.springboot3.bigevent.entity.Category;/*** Create by zjg on 2024/5/26*/
Mapper
public interface CategoryMapper extends BaseMapperCategory {
}
4. Category
package org.example.springboot3.bigevent.entity;import jakarta.validation.constraints.NotEmpty;
import lombok.Getter;
import lombok.Setter;
import lombok.ToString;
import java.time.LocalDateTime;Getter
Setter
ToString
public class Category {TableId(type IdType.AUTO)private Integer id;//主键IDNotEmpty(message 分类名称不能为空)private String categoryName;//分类名称NotEmpty(message 分类别名不能为空)private String categoryAlias;//分类别名private Integer createUser;//创建人IDprivate LocalDateTime createTime;//创建时间private LocalDateTime updateTime;//更新时间
}
二、测试
1. 失败(校验) 2.正常 总结
