8. 使用ueditor添加文章
ueditor是一个很好用的html编辑器，不仅提供了格式化编辑文本的功能，还提供了自动上传图片的功能，现在就使用该编辑器来实现博客文章的编辑功能。
1. 使用ueditor过程中会请求一个后台js文件作为语言文件，不加处理的话中文会乱码，所以要修改http的编码方式，即在application.properties中添加如下配置：
spring.http.encoding.force=true
spring.http.encoding.charset=UTF-8
spring.http.encoding.enabled=true
server.tomcat.uri-encoding=UTF-8
2. 将ueditor的整个资源放在static目录下；
3. 因为下载的时jsp版本的ueditor，而这个版本是依赖一个jsp文件运行的，所以这儿需要对ueditor的ueditor.config.js文件做修改，以使请求指向到指定的动作上，修改如下
//, serverUrl: URL + "jsp/controller.jsp"
, serverUrl:"/admin/config"
4. 在AdminController中添加config动作
1 @RequestMapping(value="/config") 2 @ResponseBody 3 public String config(String action, HttpServletRequest request, HttpServletResponse response) throws Exception { 4 if("config".equals(action)) { 5 File resource = ResourceUtils.getFile("classpath:config.json"); 6 String str = StringUtil.ReadFile(resource, "GB2312"); 7 return str; 8 } else if("uploadimage".equals(action)) { 9 StandardMultipartHttpServletRequest multipartRequest = (StandardMultipartHttpServletRequest)request; 10 if(multipartRequest != null) { 11 MultipartFile file = multipartRequest.getFile("upfile"); 12 UploadState state = new UploadState(); 13 String url = UploadUtil.imgUpLoad(file); 14 state.setUrl(url); 15 state.setState("SUCCESS"); 16 state.setOriginal(file.getName()); 17 state.setType(url.substring(url.lastIndexOf('.'))); 18 return JsonUtil.toJson(state); 19 } 20 } 21 return ""; 22 }
因为这儿主要是用到了ueditor的图片上传功能，而这样也就只用关心ueditor的配置请求和上传图片请求，所以根据action参数的值，如果是config就表示ueditor请求获取配置信息，这样就直接从后台读取config.json的内容返回给前台即可；如果是uploadimage，则是上传请求，这样就要处理文件的上传，然后返回UploadState对象对应的json即可，如此就完成了ueditor的配置和上传图片的功能；
5. 添加ArticleController，响应文件上传：
1 package com.lvniao.blog.admin.controller; 2 3 import java.util.Date; 4 5 import javax.servlet.http.HttpSession; 6 7 import org.springframework.beans.factory.annotation.Autowired; 8 import org.springframework.stereotype.Controller; 9 import org.springframework.ui.Model; 10 import org.springframework.web.bind.annotation.RequestMapping; 11 import org.springframework.web.bind.annotation.ResponseBody; 12 13 import com.lvniao.blog.mapper.ArticleMapper; 14 import com.lvniao.blog.model.Article; 15 import com.lvniao.blog.model.User; 16 import com.lvniao.blog.util.Constant; 17 import com.lvniao.blog.util.JsonUtil; 18 19 @Controller 20 @RequestMapping("/article") 21 public class ArticleController { 22 23 @Autowired 24 private ArticleMapper articleMapper; 25 26 @RequestMapping("/") 27 public String index(Model model) { 28 return "article/index"; 29 } 30 31 @RequestMapping("/add") 32 public String add() { 33 return "article/add"; 34 } 35 36 @RequestMapping("/addarticle") 37 public String addArticle(Article article, HttpSession session) { 38 article.setCreateTime(new Date()); 39 article.setAuthor((User)session.getAttribute(Constant.CurrentUser)); 40 articleMapper.insertArticle(article); 41 return "article/add"; 42 } 43 44 @RequestMapping(value="/category", produces="application/json;charset=utf-8") 45 @ResponseBody 46 public String category() { 47 return JsonUtil.toJson(articleMapper.getCategorys()); 48 } 49 }
6 添加文件上传页面
