配置
Java sdk主要包括五个配置选项,分别是
- 证书配置(必须)
- 网络连接配置 (必须)
- AMOP配置(非必须)
- 账户配置(非必须,不配置则使用默认配置值)
- 线程池配置(非必须,不配置则使用默认配置值)
支持的配置格式,包括
- toml(默认)
- properties
- yml
- xml
其中properties
、yml
和xml
格式的配置文件示例及使用方法详见4. 其它格式的配置
-
在您的应用的主目录下新建一个
conf
目录。 -
从节点
nodes/${ip}/sdk/
目录下的证书拷贝到新建的conf
目录。 -
将配置文件config-example.toml, 存放在应用的主目录下。
-
修改config-example.toml中节点的IP和端口,与您要连接的节点所匹配。
[network] peers=["127.0.0.1:20200", "127.0.0.1:20201"]
-
在您的应用中使用该配置文件初始化Java SDK,您就可以开发区块链应用了。
String configFile = "config-example.toml"; BcosSDK sdk = BcosSDK.build(configFile);
关于如何在业务项目中引入以及配置Java SDK的进一步详细说明,可参考例子。对一项目,完成Java SDK引入、配置文件及证书放置、编译后,项目的dist目录结构如下:

│ └── XXXXX.jar

Java sdk主要包括五个配置选项,分别是
- 证书配置(必须)
- 网络连接配置 (必须)
- AMOP配置(非必须)
- 账户配置(非必须,不配置则使用默认配置值)
- 线程池配置(非必须,不配置则使用默认配置值)
基于安全考虑,Java SDK与节点间采用SSL加密通信,目前同时支持非国密SSL连接以及国密SSL连接,[cryptoMaterial]
配置SSL连接的证书信息,具体包括如下配置项:
-
certPath
: 证书存放路径,默认是conf
目录; -
caCert
: CA证书路径,默认注释该配置项,该配置项注释时,当SDK与节点间采用非国密SSL连接时,默认的CA证书路径为${certPath}/ca.crt
,当SDK与节点采用国密SSL连接时,默认的CA证书路径为${certPath}/gm/gmca.crt
;开启该配置项时,从配置指定的路径加载CA证书; -
sslCert
: SDK证书路径,默认注释该配置项,该配置项注释时,当SDK与节点间采用非国密SSL连接时,从${certPath}/sdk.crt
加载SDK证书,当SDK与节点间采用国密SSL连接时,从${certPath}/gm/gmsdk.crt
加载SDK证书;开启该配置选项时,从配置指定的路径加载SDK证书; -
sslKey
: SDK私钥路径,默认注释该配置项,当该配置项注释时,当SDK与节点间采用非国密SSL连接时,从${certPath}/sdk.key
加载SDK私钥,SDK与节点采用国密SSL连接时,从${certPaht}/gm/gmsdk.key
加载SDK私钥;开启该配置项时,直接从配置项指定的路径加载SDK私钥; -
enSslCert
: 国密SSL加密证书路径,仅当SDK与节点间采用国密SSL连接时,需要配置该配置项,默认从${certPath}/gm/gmensdk.crt
加载国密SSL加密证书;当开启该配置项时,从配置项指定的路径加载国密SSL加密证书; -
enSslKey
: 国密SSL加密私钥路径,仅当SDK与节点间采用国密SSL连接时,需配置该配置项,默认从${certPath}/gm/gmensdk.key
加载国密SSL加密私钥;当卡其该配置项时,从配置项指定的路径加载国密SSL加密私钥。
.. note::
- 大部分场景仅需要配置 `certPath` 配置项即可,其他配置项不需额外配置;
- SDK证书获取:若参考 `安装 <../../installation.html>`_ 搭建区块链,则参考 `这里 <../../installation.html#id7>`_ 将 `nodes/${ip}/sdk/` 目录下的证书拷贝到 `certPath` 指定的路径;若区块链节点参考 `运维部署工具 <../../enterprise_tools/index.html>`_ 搭建,则参考 `这里 <../../enterprise_tools/tutorial_one_click.html#id15>`_ 将 `generator/meta` 文件夹下的SDK证书拷贝到 `certPath`指定路径;
- SDK与节点间SSL连接方式,可通过节点配置项 `sm_crypto_channel` 判断,该配置项详细说明请参考 `FISCO BCOS配置文件与配置项说明 <../../manual/configuration.html#id10>`_ .
SDK证书配置示例如下:
[cryptoMaterial]
certPath = "conf" # The certification path
# The following configurations take the certPath by default if commented
# caCert = "conf/ca.crt" # CA cert file path
# If connect to the GM node, default CA cert path is ${certPath}/gm/gmca.crt
# sslCert = "conf/sdk.crt" # SSL cert file path
# If connect to the GM node, the default SDK cert path is ${certPath}/gm/gmsdk.crt
# sslKey = "conf/sdk.key" # SSL key file path
# If connect to the GM node, the default SDK privateKey path is ${certPath}/gm/gmsdk.key
# enSslCert = "conf/gm/gmensdk.crt" # GM encryption cert file path
# default load the GM SSL encryption cert from ${certPath}/gm/gmensdk.crt
# enSslKey = "conf/gm/gmensdk.key" # GM ssl cert file path
# default load the GM SSL encryption privateKey from ${certPath}/gm/gmensdk.key
SDK与FISCO BCOS节点通信,必须配置SDK连接的节点的IP
和Port
,[network]
配置了Java SDK连接的节点信息,具体包括如下配置项:
- peers:SDK连接的节点的
IP:Port
信息,可配置多个连接。
.. note::
节点与网络之间的连接信息
SDK与节点间通过 `ChannelServer` 进行通信,SDK需要连接 `ChannelServer` 的监听端口,该端口可通过节点 `config.ini` 的 `rpc.channel_listen_port` 获取,具体请参考 `这里 <../../manual/configuration.html#rpc>`_
SDK与节点间的网络配置示例如下:
[network]
peers=["127.0.0.1:20200", "127.0.0.1:20201"] # The peer list to connect
AMOP支持私有话题的功能,配置文件中提供了AMOP
相关配置项于 [[amop]]
中。
AMOP私有话题订阅者需要配置私钥用于进行私有话题认证,具体配置项包括:
topicName
: 私有话题名称;privateKey
: 私有话题订阅者的私钥路径,用于证明订阅房身份信息;password
: 访问私钥文件的口令。
AMOP订阅私有话题的配置项示例如下:
# Configure a private topic as a topic subscriber.
[[amop]]
topicName = "PrivateTopic"
privateKey = "conf/amop/consumer_private_key.p12" # Your private key that used to subscriber verification.
password = "123456"
AMOP私有话题认证成功后,消息发布方可向订阅方发送私有话题消息,发布私有话题消息的配置包括:
topicName
: 私有话题名称;publicKeys
: 消息订阅方的公钥列表。
AMOP发布私有话题消息的配置示例如下:
# Configure a private topic as a topic message sender.
[[amop]]
topicName = "PrivateTopic"
publicKeys = [ "conf/amop/consumer_public_key_1.pem" ] # Public keys of the nodes that you want to send AMOP message of this topic to.
账户配置主要用于设置SDK向节点发交易的账户信息,SDK初始化client时,默认读取[account]
配置项加载账户信息,具体如下:
-
keyStoreDir
: 加载/保存账户文件的路径,默认为account
; -
accountFileFormat
: 账户文件格式,默认为pem
,目前仅支持pem
和p12
,pem
格式的账户文件不需要口令加载,加载p12
格式的账户文件时需要口令; -
accountAddress
: 加载的账户地址,默认为空 -
accountFilePath
: 加载的账户文件路径,默认注释该配置项,注释该配置项时,当SDK连接非国密区块链时,默认从${keyStoreDir}/ecdsa/${accountAddress}.${accountFileFormat}
路径加载账户文件,当SDK连接国密区块链时,默认从${keyStoreDir}/gm/${accountAddress}.${accountFileFormat}
路径加载账户;当开启该配置项时,从该配置项指定的目录加载账户; -
password
: 加载p12
类型账户文件的口令。
.. note::
当没有配置 `accountAddress` 和 `accountFilePath` 时,SDK会生成随机的账户向节点交易,生成的账户信息均保存在 `keyStoreDir` 配置项指定的目录下:当SDK连接节点是非国密节点时,生成的临时账户以 `pem` 的格式保存在 `${keyStoreDir}/ecdsa/` 目录下;当SDK连接的节点时国密节点时,生成的临时账户以 `p12` 的格式保存在 `${keyStoreDir}/gm` 目录下
账户配置文件示例如下:
[account]
keyStoreDir = "account" # The directory to load/store the account file, default is "account"
# accountFilePath = "" # The account file path (default load from the path specified by the keyStoreDir)
accountFileFormat = "pem" # The storage format of account file (Default is "pem", "p12" as an option)
# accountAddress = "" # The transactions sending account address
# Default is a randomly generated account
# The randomly generated account is stored in the path specified by the keyStoreDir
# password = "" # The password used to load the account file
为了方便业务根据机器实际负载调整SDK的处理线程,Java SDK将其线程配置项暴露在配置中,[threadPool]
是线程池相关配置,具体包括:
-
channelProcessorThreadSize
: 处理网络回调的线程数目,默认注释该配置项,注释该配置项时,其默认值为机器的CPU数目;开启该配置项时,根据配置的值创建处理网络回调的线程数目; -
receiptProcessorThreadSize
: 接收交易的线程数目,默认注释该配置项,注释该配置项时,默认值为机器的CPU数目;开启该配置项时,根据配置的值创建接收交易的线程数目; -
maxBlockingQueueSize
: 线程池队列等待被处理的最大任务数目,默认为102400。
.. note::
大多数场景下,不需要手工配置线程池配置;压测场景下,可将 `maxBlockingQueueSize` 配置大一些。
线程池配置示例如下:
[threadPool]
# channelProcessorThreadSize = "16" # The size of the thread pool to process channel callback
# Default is the number of cpu cores
# receiptProcessorThreadSize = "16" # The size of the thread pool to process transaction receipt notification
# Default is the number of cpu cores
maxBlockingQueueSize = "102400" # The max blocking queue size of the thread pool
config-example.toml
[cryptoMaterial]
certPath = "conf" # The certification path
# The following configurations take the certPath by default if commented
# caCert = "conf/ca.crt" # CA cert file path
# If connect to the GM node, default CA cert path is ${certPath}/gm/gmca.crt
# sslCert = "conf/sdk.crt" # SSL cert file path
# If connect to the GM node, the default SDK cert path is ${certPath}/gm/gmsdk.crt
# sslKey = "conf/sdk.key" # SSL key file path
# If connect to the GM node, the default SDK privateKey path is ${certPath}/gm/gmsdk.key
# enSslCert = "conf/gm/gmensdk.crt" # GM encryption cert file path
# default load the GM SSL encryption cert from ${certPath}/gm/gmensdk.crt
# enSslKey = "conf/gm/gmensdk.key" # GM ssl cert file path
# default load the GM SSL encryption privateKey from ${certPath}/gm/gmensdk.key
[network]
peers=["127.0.0.1:20200", "127.0.0.1:20201"] # The peer list to connect
# AMOP configuration
# You can use following two methods to configure as a private topic message sender or subscriber.
# Usually, the public key and private key is generated by subscriber.
# Message sender receive public key from topic subscriber then make configuration.
# But, please do not config as both the message sender and the subscriber of one private topic, or you may send the message to yourself.
# Configure a private topic as a topic message sender.
# [[amop]]
# topicName = "PrivateTopic"
# publicKeys = [ "conf/amop/consumer_public_key_1.pem" ] # Public keys of the nodes that you want to send AMOP message of this topic to.
# Configure a private topic as a topic subscriber.
# [[amop]]
# topicName = "PrivateTopic"
# privateKey = "conf/amop/consumer_private_key.p12" # Your private key that used to subscriber verification.
# password = "123456"
[account]
keyStoreDir = "account" # The directory to load/store the account file, default is "account"
# accountFilePath = "" # The account file path (default load from the path specified by the keyStoreDir)
accountFileFormat = "pem" # The storage format of account file (Default is "pem", "p12" as an option)
# accountAddress = "" # The transactions sending account address
# Default is a randomly generated account
# The randomly generated account is stored in the path specified by the keyStoreDir
# password = "" # The password used to load the account file
[threadPool]
# channelProcessorThreadSize = "16" # The size of the thread pool to process channel callback
# Default is the number of cpu cores
# receiptProcessorThreadSize = "16" # The size of the thread pool to process transaction receipt notification
# Default is the number of cpu cores
maxBlockingQueueSize = "102400" # The max blocking queue size of the thread pool
Java SDK还支持properties
