FastDFS实战（五）- Spring Boot集成FastDFS

源码下载地址：https://github.com/tobato/FastDFS_Client

一、 创建Spring Boot项目，并导入fastdfs依赖

<dependency>
    <groupId>com.github.tobatogroupId>
    <artifactId>fastdfs-clientartifactId>
    <version>1.25.2-RELEASEversion>
dependency>

二、配置

1. 入口类

   package com.baizhi;
   
   import com.github.tobato.fastdfs.FdfsClientConfig;
   import org.springframework.boot.SpringApplication;
   import org.springframework.boot.autoconfigure.SpringBootApplication;
   import org.springframework.context.annotation.EnableMBeanExport;
   import org.springframework.context.annotation.Import;
   import org.springframework.jmx.support.RegistrationPolicy;
   
   @Import(FdfsClientConfig.class)
   // 解决jmx重复注册bean的问题
   @EnableMBeanExport(registration = RegistrationPolicy.IGNORE_EXISTING)
   
   @SpringBootApplication
   public class FastdfsClientApplication {
   
       public static void main(String[] args) {
           SpringApplication.run(FastdfsClientApplication.class, args);
       }
   }

2. application.yml

   
   # =========================================================
   
   
   # 分布式文件系统FDFS配置
   
   
   # =========================================================
   
   fdfs:
     soTimeout: 30
     connectTimeout: 60
     thumbImage:             #缩略图生成参数
       width: 150
       height: 150
     trackerList:            #TrackerList参数,支持多个
       - 192.168.128.141:22122
     pool:
       max-total: 100
       max-wait-millis: 60

3. 测试
