gridfs + nginx + mongodb 实现图片服务器

项目预览网址 : http://trans.waibaobao.cn/file/pics

安装:前提安装mongodb 作为文件储存库

1)nginx-gridfs安装

a、安装所用依赖包 yum -y install pcre-devel openssl-devel zlib-devel git gcc gcc-c++

b、下载nginx-gridfs 源代码 git clone https://github.com/mdirolf/nginx-gridfs.git(前提安装git)

进入nginx-gridfs 后

git checkout v0.8

git branch

git submodule init

git submodule update

2)a、nginx 下载安装 
wget http://nginx.org/download/nginx-1.14.2.tar.gz      解压 tar -zxvf nginx-1.14.2.tar.gz

b、进入nginx-1.14.2后
./configure --prefix=/usr/local/nginx   --with-openssl=/usr/include/openssl --add-module=../nginx-mongodb/nginx-gridf

c、make -j8 && make install -j8 (此时会多个nginx目录)

我的报错了

d、vi objs/Makefile  把第3行的-Werror错误去后  make -j8 && make install -j8

e、进入nginx的配置文件更改

    server {
        listen       10010;
        server_name  localhost;

          location /pics/ {
            gridfs zrdb
            field=filename
            type=string;
            mongo 127.0.0.1:27017;
        }

    }

test 代表mongodb 数据库名

pics 为配置java 访问mongodb的访问路径

mongodb.url=http://47.106.32.125/pics/
ivs.mongodb.host=47.106.32.125
ivs.mongodb.port=27017
ivs.mongodb.database=test

ok！！！

下面说下java 怎么实现连接mongodb 数据库

话不多说上代码：

1）配置类 加载mongodb dev 的配置文件

package com.fyun.tewebcore.config;

import com.fasterxml.jackson.core.JsonGenerator;
import com.fasterxml.jackson.core.JsonProcessingException;
import com.fasterxml.jackson.databind.JsonSerializer;
import com.fasterxml.jackson.databind.SerializerProvider;
import com.mongodb.MongoClientOptions;
import org.apache.commons.lang3.StringUtils;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.PropertySource;
import org.springframework.stereotype.Component;

import java.io.IOException;

@Component
@PropertySource("classpath:/config/mongodb-${spring.profiles.active:dev}.properties")
@Configuration
public class MongoConfig extends JsonSerializer<String> {
    public static String mongodbUrl;

    public static String urlKey = "mongodbUrl";

    @Override
    public void serialize(String String, JsonGenerator jsonGenerator, SerializerProvider serializerProvider) throws IOException, JsonProcessingException {
        if (StringUtils.isNotEmpty(String))
            jsonGenerator.writeString(mongodbUrl + String);
        else
            jsonGenerator.writeString(" ");
    }

    @Value("${mongodb.url}")
    public void setMongodbUrl(String mongodbUrl) {
        MongoConfig.mongodbUrl = mongodbUrl;
    }

    @Bean
    public MongoClientOptions mongoOptions(){
        return MongoClientOptions.builder().maxConnectionIdleTime(3000).build();
    }
}

2）写一个文件上传controller

package com.fyun.tewebcore.Controller.file;
import com.fyun.common.model.base.CommonResponse;
import com.fyun.common.model.base.SystemCode;
import com.fyun.common.utils.file.MongoGridfsServiceImpl;
import com.fyun.common.utils.util.StringUtils;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.*;
import org.springframework.web.multipart.MultipartFile;
import org.springframework.web.multipart.commons.CommonsMultipartFile;
import javax.servlet.http.HttpServletResponse;
/**
 * @author zhourui
 * @create 2019/12/31
 */
@Api("文件上传处理器")
@RestController
@RequestMapping("/file")
public class FileController {
    private static final Logger logger= LoggerFactory.getLogger(FileController.class);
    @Autowired
    private MongoGridfsServiceImpl mongoGridfsService;
    @ApiOperation(value = "文件上传")
    @RequestMapping(value = "/upload", method = RequestMethod.POST)
    @ResponseBody
    public CommonResponse upload(@RequestParam(value = "file",required = false) MultipartFile commonsMultipartFile, HttpServletResponse responses) {
        responses.addHeader("Access-Control-Allow-Origin", "*");
        CommonResponse response = new CommonResponse();
        logger.info("#commonsMultipartFile==getOriginalFilename入参" +commonsMultipartFile.getOriginalFilename());
        logger.info("#commonsMultipartFile==入参" +commonsMultipartFile);
        logger.info("#commonsMultipartFile入参" +commonsMultipartFile.getContentType());
        try {
            String fileName = StringUtils.getFileName(commonsMultipartFile.getOriginalFilename().substring(commonsMultipartFile.getOriginalFilename().lastIndexOf(".")));
            logger.info("#文件名称=="+fileName);
            mongoGridfsService.save(commonsMultipartFile.getInputStream(),fileName);
            response.setCode(SystemCode.SYSTEM_SUCCESS.getCode());
            response.setMessage(SystemCode.SYSTEM_SUCCESS.getMessage());
            response.setData(fileName);
            return response;
        } catch (Exception e) {
            logger.error("未知异常");
            response.setCode(SystemCode.FILE_UPLOAD_EXCEPTION.getCode());
            response.setMessage(SystemCode.FILE_UPLOAD_EXCEPTION.getMessage()+e.getMessage());
            return response;
        }
    }
}

3）调服务接口对gridfs实现增删改查

package com.fyun.common.utils.file;
import com.mongodb.BasicDBObject;
import com.mongodb.DB;
import com.mongodb.DBObject;
import com.mongodb.MongoClient;
import com.mongodb.gridfs.GridFS;
import com.mongodb.gridfs.GridFSDBFile;
import com.mongodb.gridfs.GridFSInputFile;
import org.apache.commons.lang3.StringUtils;
import org.apache.log4j.Logger;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.PropertySource;
import org.springframework.stereotype.Service;

import javax.annotation.PostConstruct;
import java.io.*;
import java.util.List;

/**

            gridFS = new GridFS(db);
        } catch (Exception e) {
