其中lombok不是必须的

# 数据库与配置 #

![在这里插入图片描述][20210115143857106.png]  
就id 标题名 作者 主体内容

mybaits 和映射之类的就不说了 就一个插入语句

没有弄service 处于方便直接用dao来调用了

**application.yml**

server:
      port: 8081
    
    spring:
      datasource:
        driver-class-name: com.mysql.cj.jdbc.Driver
        url: jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=utf-8&useSSL=false&serverTimezone=UTC&allowPublicKeyRetrieval=true
        username: root
        password: 123456
    
    mybatis:
      mapper-locations: classpath:/mapper/*.xml

# 静态资源过滤 #

如果不过滤 映射的地址将会出错 这里选择了用java代码的方式来实现

@Configuration
    public class MyMvcConfig implements WebMvcConfigurer { 
    
        @Override
        public void addResourceHandlers(ResourceHandlerRegistry registry) { 
            //过滤静态资源 会到这个目录里 为markdown图片上传做准备
            registry.addResourceHandler("/upload/**")
                    .addResourceLocations("file:" + FileUtil.PATH);
        }
    
    }

**注意 这里用到了工具类 下面会有他的实现**

关于静态过滤的小知识 给大家贴出来

![在这里插入图片描述][20210115144308107.png_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDM1MzUwNw_size_16_color_FFFFFF_t_70]

# 工具类 #

public class FileUtil { 
        //文件存放的路径 若没有 会自动创建
        public static final String PATH=System.getProperty("user.dir")+"/src/main/resources/static/upload/";
        /** * 上传文件 如果上传错误 会返回空的地址 注意 返回的地址是用来回显的 所以不要返回布尔类型 */
        public static String upload(MultipartFile multipartFile) { 
            if(multipartFile.isEmpty()) { 
                return "";
            }
            String filename = multipartFile.getOriginalFilename();
            File file = new File(PATH);
            if (!file.exists()) { 
                //使用mkdirs 若某个目录不存在 也会一起创建
                file.mkdirs();
            }
            //为了不使得图片名字重复 使用uuid拼接
            int i = filename.lastIndexOf(".");
            String suffix = filename.substring(i-1);
            String newFileName = UUID.randomUUID().toString() + suffix;
            try { 
                multipartFile.transferTo(new File(PATH+newFileName));
            } catch (IOException e) { 
                e.printStackTrace();
                return "";
            }
            return newFileName;
        }
    }

# controller #

![在这里插入图片描述][20210115144524742.png]  
这里用到的articleDAO 只实现了一个插入的方法(用的插件实现 一键生成)

@Controller
    public class ArticleController { 
    
        @Autowired
        private ArticleDAO articleDAO;
    
        @GetMapping("edit")
        public String edit() { 
            return "edit";
        }
    
        @PostMapping("edit/upload")
        @ResponseBody
        public JSONObject fileUpload(@RequestParam(value = "editormd-image-file", required = true) MultipartFile file, HttpServletRequest request) throws IOException { 
            String uploadname = FileUtil.upload(file);
            //给editormd进行回调
            JSONObject res = new JSONObject();
            res.put("url", "/upload/" + uploadname);
            res.put("success", 1);
            res.put("message", "upload success!");
            return res;
        }
    
        @PostMapping("save")
        @ResponseBody
        public String save(Article article) { 
            System.out.println(article);
            int i = articleDAO.insertSelective(article);
            if (i == 1) { 
                System.out.println(1111);
                return "发布成功";
            } else { 
                System.out.println(2222);
                return "失败了....";
            }
    
        }
    }

# editormd #

这里直接给出整理好的文件夹 因为一个个的引入太麻烦了 直接用就好了

目录结构是这样的

注意 我对文件进行了修改操作 若是用原版的 则可能出现  
`Uncaught SyntaxError: Unexpected token in JSON at position 0` 之类的错误

这是因为第三方插件导致的 **非常坑**

具体解决看这里 我给的文件已经修改过了

# 前端页面 #

需要引入editormd.css jq和editormd.js
