使用ant从源码构建

ant clean package

使用maven从源码安装

mvn clean install

使用maven从jar文件安装

mvn install:install-file -DgroupId=org.csource -DartifactId=fastdfs-client-java -Dversion=${version} -Dpackaging=jar -Dfile=fastdfs-client-java-${version}.jar

.conf 配置文件、所在目录、加载优先顺序

配置文件名fdfs_client.conf(或使用其它文件名xxx_yyy.conf)

文件所在位置可以是项目classpath(或OS文件系统目录比如/opt/):
/opt/fdfs_client.conf
C:\Users\James\config\fdfs_client.conf

优先按OS文件系统路径读取,没有找到才查找项目classpath,尤其针对linux环境下的相对路径比如:
fdfs_client.conf
config/fdfs_client.conf
connect_timeout = 2
network_timeout = 30
charset = UTF-8
http.tracker_http_port = 80
http.anti_steal_token = no
http.secret_key = FastDFS1234567890

tracker_server = 10.0.11.247:22122
tracker_server = 10.0.11.248:22122
tracker_server = 10.0.11.249:22122
注1:tracker_server指向您自己IP地址和端口,1-n个
注2:除了tracker_server,其它配置项都是可选的

.properties 配置文件、所在目录、加载优先顺序

配置文件名 fastdfs-client.properties(或使用其它文件名 xxx-yyy.properties)

文件所在位置可以是项目classpath(或OS文件系统目录比如/opt/):
/opt/fastdfs-client.properties
C:\Users\James\config\fastdfs-client.properties

优先按OS文件系统路径读取,没有找到才查找项目classpath,尤其针对linux环境下的相对路径比如:
fastdfs-client.properties
config/fastdfs-client.properties
fastdfs.connect_timeout_in_seconds = 5
fastdfs.network_timeout_in_seconds = 30
fastdfs.charset = UTF-8
fastdfs.http_anti_steal_token = false
fastdfs.http_secret_key = FastDFS1234567890
fastdfs.http_tracker_http_port = 80

fastdfs.tracker_servers = 10.0.11.201:22122,10.0.11.202:22122,10.0.11.203:22122
注1:properties 配置文件中属性名跟 conf 配置文件不尽相同,并且统一加前缀"fastdfs.",便于整合到用户项目配置文件
注2:fastdfs.tracker_servers 配置项不能重复属性名,多个 tracker_server 用逗号","隔开
注3:除了fastdfs.tracker_servers,其它配置项都是可选的

加载配置示例

加载原 conf 格式文件配置:
ClientGlobal.init("fdfs_client.conf");
ClientGlobal.init("config/fdfs_client.conf");
ClientGlobal.init("/opt/fdfs_client.conf");
ClientGlobal.init("C:\\Users\\James\\config\\fdfs_client.conf");

加载 properties 格式文件配置:
ClientGlobal.initByProperties("fastdfs-client.properties");
ClientGlobal.initByProperties("config/fastdfs-client.properties");
ClientGlobal.initByProperties("/opt/fastdfs-client.properties");
ClientGlobal.initByProperties("C:\\Users\\James\\config\\fastdfs-client.properties");

加载 Properties 对象配置:
Properties props = new Properties();
props.put(ClientGlobal.PROP_KEY_TRACKER_SERVERS, "10.0.11.101:22122,10.0.11.102:22122");
ClientGlobal.initByProperties(props);

加载 trackerServers 字符串配置:
String trackerServers = "10.0.11.101:22122,10.0.11.102:22122";
ClientGlobal.initByTrackers(trackerServers);

检查加载配置结果:

System.out.println("ClientGlobal.configInfo(): " + ClientGlobal.configInfo());
ClientGlobal.configInfo(): {
  g_connect_timeout(ms) = 5000
  g_network_timeout(ms) = 30000
  g_charset = UTF-8
  g_anti_steal_token = false
  g_secret_key = FastDFS1234567890
  g_tracker_http_port = 80
  trackerServers = 10.0.11.101:22122,10.0.11.102:22122
}
