闪耀的瞬间-SpringBoot Mongodb文件存储服务器
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
