在Webase平台上部署好智能合约，并检查能够正常发交易实现增删查改后，我们还需要使其能够与java交互来实现一个可用于应用的系统。在项目中，我们需要新建四个文件夹，一个用于存放java类型文件，一个用来存放abi文件，一个用来存放bin文件，一个用来存放证书文件。本文使用的是maven方法！,文件夹名最好就按图中的来！

一.智能合约编译与虚拟机文件导入

        首先将我们的合约进行编译。

<code>bash sol2java.sh -p org.fisco.bcos.asset.contract

        然后从虚拟机导入我们需要的文件（用mobaxterm实现主机与虚拟机之间的连接,如果permission denied检查是否在有权限的文件夹下,，可以通过chmod 777 text修改文件权限以下载！）

java文件、bin文件、编译好的abi文件一般在 fisco/console/contracts/sdk文件夹下。

证书文件在webase-deploy/nodes/127.0.0.1/sdk文件夹下。

                将java文件移到fisco文件夹下

        将abi文件移到我们新建的abi文件夹下

        将bin文件移到我们新建的bin文件夹下

        将证书文件移到我们新建的config 文件夹下

        移动完之后的项目文件

        检查java文件，将包名改为自己的包名。

        发现仍有很多报错，原因是我们还没有注入fisco的依赖，这里演示如何在maven文件注入fisco依赖，注意这篇文章讲的不是gradle文件还是maven文件！ 

        在pom.xml下注入以下依赖。如果报错则等待一会，注入后刷新。

<code><dependency>

<groupId>org.fisco-bcos.java-sdk</groupId>

<artifactId>fisco-bcos-java-sdk</artifactId>

<version>2.9.1</version>

</dependency>

        报错解决

二.创建配置文件

        首先，在idea中新建config-example.toml文件，注意位置需与applictions.properties同级！

 在config-example.toml文件中写入以下内容：

<code>[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

找到

，将其中的ip地址改为虚拟机中的地址，配置文件修改完成。

三.调用测试类检查功能

       在idea中创建测试类。获取配置文件路径。

<code>public final String configFile = "src/main/resources/config-example.toml";

        初始准备工作： 

     三.1 初始化SDK

<code>// 初始化BcosSDK对象

BcosSDK sdk = BcosSDK.build(configFile);

// 获取Client对象，此处传入的群组ID为1

Client client = sdk.getClient(Integer.valueOf(1));

// 构造AssembleTransactionProcessor对象，需要传入client对象，CryptoKeyPair对象和abi、

binary文件存放的路径。abi和binary文件需要在上一步复制到定义的文件夹中。

CryptoKeyPair keyPair = client.getCryptoSuite().createKeyPair();

        三.2 初始化配置对象

AssembleTransactionProcessor transactionProcessor = TransactionProcessorFactory.createAssembleTransactionProcessor(client, keyPair, "src/main/resources/abi/", "");

        三.3 进行交易测试

        这里，交易测试以其中一个为例，其它交易操作步骤与例子相同。

        准备函数所需要的参数：

String keyword="2";code>

String date="0721";code>

String patient_name="xiaoming";code>

String sex = "nan";

String age="18";code>

String doctor_name="xiaohong";code>

String diagnosis="ganmao";code>

        创建参数列表并写入参数

List<Object> params = new ArrayList<>();

params.add(keyword);

params.add(date);

params.add(patient_name);

params.add(sex);

params.add(age);

params.add(date);

params.add(doctor_name);

params.add(diagnosis);

        调用合约:

TransactionResponse transactionResponse = transactionProcessor.sendTransactionAndGetResponseByContractLoader("HelloWorld", helloWorldAddrss, "set", params);

其中，调用合约时的第一个参数为自己编写的智能合约的名字，第二个参数为合约地址，第三个参数为所使用的自己编写的智能合约中的函数，第四个参数为刚刚创建的params参数数组。

合约地址可以在Webase平台中的合约列表找到：

,如果有返回值还需要打印返回值。
