java调用fastdfs

在github.com中查找fastdfs （官方不支持连接池而这个是支持连接池的）

在pom中加入依赖（由于阿里云中央仓库没有这个依赖需要配置新的私服仓库）

引入私服地址

<repositories>
        <repository>
            <id>sn</id>
            <name>sn</name>
            <url>http://oss.sonatype.org/content/repositories/releases</url>
        </repository>
    </repositories>

添加fastdfs依赖

<dependency>
            <groupId>com.luhuiguo</groupId>
            <artifactId>fastdfs-spring-boot-starter</artifactId>
            <version>0.2.0</version>
        </dependency>

pom配置文件如图

application.yml配置：

server:
  port: 8899
fdfs:
  #超时时间
  connect-timeout: 1000
  #响应的超时时间
  so-timeout: 3000
  tracker-list:
    - 192.168.63.133:22122
spring:
  datasource:
    url: jdbc:mysql://localhost/factory
    password: 123456
    driver-class-name: com.mysql.jdbc.Driver
    username: root
    #上传的文件大小
  http:
    multipart:
      max-file-size: 10485760

        byte[] bt=storageClient.downloadFile(groupName,pathName);
