1.使用MongoTemplate

/**
    * 存储文件
    * @param collectionName 集合名
    * @param file 文件
    * @param fileid 文件id
    * @param companyid 文件的公司id
    * @param filename 文件名称
    */
    public void SaveFile(String collectionName, File file, String fileid, String companyid, String filename) {
        try {
            DB db = mongoTemplate.getDb();
            // 存储fs的根节点
            GridFS gridFS = new GridFS(db, collectionName);
            GridFSInputFile gfs = gridFS.createFile(file);
            gfs.put("aliases", companyid);
            gfs.put("filename", fileid);
            gfs.put("contentType", filename.substring(filename.lastIndexOf(".")));
            gfs.save();
        } catch (Exception e) {
            e.printStackTrace();
            System.out.println("存储文件时发生错误!!!");
        }
    }
 
    // 取出文件
    public GridFSDBFile retrieveFileOne(String collectionName, String filename) {
        try {
            DB db = mongoTemplate.getDb();
            // 获取fs的根节点
            GridFS gridFS = new GridFS(db, collectionName);
            GridFSDBFile dbfile = gridFS.findOne(filename);
            if (dbfile != null) {
                return dbfile;
            }
        } catch (Exception e) {
            // TODO: handle exception
        }
        return null;
    }
//抱歉项目案例不能给你,不过这个是向mongodb存取文件的实现代码,,希望能帮助到你。
//由GridFSDBFile 可以得到inputStream,这样你就明白了吧。

2.使用GridFsTemplate

网上找到的第一种方法总结的非常的不好,Spring结合的感觉不够紧密。 谷歌了下参考了下网上的文章。

Spring 伪配置


     threads-allowed-to-block-for-connection-multiplier="100"
   connect-timeout="1000" max-wait-time="1500" auto-connect-retry="true"
   socket-keep-alive="true" socket-timeout="1500" slave-ok="true"
   write-number="1" write-timeout="0" write-fsync="true" />
 

   password="***" mongo-ref="mongo" />

   db-factory-ref="mongoDbFactory" />

 
 
 
 
 
 

              abstract="true">
       
           
       

       
           
       

   

Java 伪代码

 List files = this.getGridFsTemplate().find(null); //查询全部,查询方式和MongoTemplate一样
   
   System.out.println("-----------------");
   
      for (GridFSDBFile file: files) {
        System.out.println(file);
      }
