springBoot整合FastDFS

1、maven配置

<dependency>
            <groupId>net.oschina.zcx7878</groupId>
            <artifactId>fastdfs-client-java</artifactId>
            <version>1.27.0.0</version>
</dependency>

2、resource 中新增文件 fdfs.properties

　　

# connect timeout in seconds
# default value is 30s
connect_timeout=30

# network timeout in seconds
# default value is 30s
network_timeout=60

# the base path to store log files
base_path=/usr/local/fastdfs/client

# tracker_server can ocur more than once, and tracker_server format is
#  "host:port", host can be hostname or ip address
tracker_server=192.168.0.44:22122
#tracker_server=192.168.0.5:22122

#standard log level as syslog, case insensitive, value list:
### emerg for emergency
### alert
### crit for critical
### error
### warn for warning
### notice
### info
### debug
log_level=info

# if use connection pool
# default value is false
# since V4.05
use_connection_pool = false

# connections whose the idle time exceeds this time will be closed
# unit: second
# default value is 3600
# since V4.05
connection_pool_max_idle_time = 3600

# if load FastDFS parameters from tracker server
# since V4.05
# default value is false
load_fdfs_parameters_from_tracker=false

# if use storage ID instead of IP address
# same as tracker.conf
# valid only when load_fdfs_parameters_from_tracker is false
# default value is false
# since V4.05
use_storage_id = false

# specify storage ids filename, can use relative or absolute path
# same as tracker.conf
# valid only when load_fdfs_parameters_from_tracker is false
# since V4.05
storage_ids_filename = storage_ids.conf

#HTTP settings
http.tracker_server_port=8080

#use "#include" directive to include HTTP other settiongs
##include http.conf

 3、application.yml配置

#fdfs 配置信息 tracker IP端口
httpUrl: http://192.168.0.44:8080/
#fdfs 配置文件名称
fdfsPropertiesName: fdfs.properties

 

4、代码

public class FileController {

    @Value("${httpUrl}")
    private String HTTP_URL;

    @Value("${fdfsPropertiesName}")
    private String CONF_FILENME;

    @ApiOperation("上传图片")

            //参数一为文件所在的路径（不要有中文）

            //upload_file 存储着访问路径
            for (String s : upload_file) {
                System.out.println(s);
            }
            imageUrl.append(upload_file[0] + "/" + upload_file[1]);
