SpringBoot整合FastDFS
SpringBoot 整合FastDFS(附工具类，和源码地址)
源码地址： https://github.com/Lijun54321/fastdfs-test
1. 利用idea 创建一个 Springboot 项目
这里就不介绍了这个步骤了
2. 导入 maven 依赖
<dependency>
<groupId>com.github.tobatogroupId>
<artifactId>fastdfs-clientartifactId>
<version>1.26.7version>
dependency>
3. 引入配置
启动类上直接加就行了，没必要去写一个配置类
package com.test.fastdfs;
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;
/**
* EnableMBeanExport 解决Jmx重复注册bean的问题
*
* @author 16634
*/
@Import(FdfsClientConfig.class)
@EnableMBeanExport(registration = RegistrationPolicy.IGNORE_EXISTING)
@SpringBootApplication
public class FastdfsApplication {
public static void main(String[] args) {
SpringApplication.run(FastdfsApplication.class, args);
}
}
4. 配置文件
我这是yml 文件，如果需要些properties文件的话，可以自己转换下(btw：idea 有yml转pro pro转yml 插件哟)
spring:
servlet:
multipart:
# 开启文件上传功能
enabled: true
max-file-size: 100MB
max-request-size: 100MB
# fastDFS 配置
fdfs:
# 连接超时
connect-timeout: 60
# 读取时间
so-timeout: 15000
# 生成缩略图参数
thumb-image:
width: 150
height: 150
# 支持配置多个
tracker-list:
- 192.168.1.1:22122
- ip1:port
- ip2:port

6. FastDfsUtils 工具类
btw 这只是测试的，一般我们正常开发的时候，做好异常捕捉操作哦!
package com.test.fastdfs.utils;
import com.github.tobato.fastdfs.domain.fdfs.StorePath;
import com.github.tobato.fastdfs.domain.proto.storage.DownloadByteArray;

import org.springframework.web.multipart.MultipartFile;
import java.io.*;
import java.nio.charset.StandardCharsets;

}

public byte[] downloadFile(String fileUrl) {

String path = fileUrl.substring(fileUrl.indexOf("/") + 1);
DownloadByteArray downloadByteArray = new DownloadByteArray();
return fastFileStorageClient.downloadFile(group, path, downloadByteArray);
}
public void deleteFile(String fileUrl) {
if (StringUtils.isBlank(fileUrl)) {
return;
}
try {
