闪耀的瞬间-SpringBoot Mongodb文件存储服务器

源码下载-mongo-upload

1.依賴

<!--        mongodb-->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-mongodb</artifactId>
</dependency>

2.配置

spring:
  # mongodb
  data:
    mongodb:
#      uri: mongodb://127.0.0.1:27017/commentdb  # 或者使用这种方式
      database: test
      host: 127.0.0.1
      port: 27017
      password:
# 文件大小
  servlet:
    multipart:
      max-file-size: 50MB
      max-request-size: 50MB

3.文件实体类

import lombok.Data;
import lombok.EqualsAndHashCode;
import lombok.ToString;
import org.springframework.data.annotation.Id;
import org.springframework.data.mongodb.core.mapping.Document;

import java.util.Date;

@Document
@Data
@ToString
@EqualsAndHashCode
public class FileDocument {

    @Id  // 主键
    private String id;
    private String name;        // 文件名称
    private long size;          // 文件大小
    private Date uploadDate;    // 上传时间
    private String md5;         // 文件MD5值
    private byte[] content;     // 文件内容
    private String contentType; // 文件类型
    private String suffix;      // 文件后缀名
    private String description; // 文件描述
    private String gridfsId;    // 大文件管理GridFS的ID

}
