spring boot 实现fisco bcos最基础案例
- 一、基于国密搭建的4个节点联盟链
- 1.1 依赖文件
- 1.2 config.toml配置文件
- 1.3 用工具编译Helloworld.sol生成Hellolworld.java文件
- 1.4 调用合约方法
- 二、注意的点
- 2.1 spring-boot版本不宜过高
- 2.2 读取项目根路径
- 三、spring boot接口搭建
- 3.1 去掉数据库配置
- 3.2 tomcat正常启动,localhost访问不到接口
- 3.3 lombok不起作用

1.3 用工具编译Helloworld.sol生成Hellolworld.java文件
- 注意Helloworld所在包的目录

}1.4 调用合约方法
import org.com.fisco.HelloWorld;
import org.fisco.bcos.sdk.BcosSDK;
import org.fisco.bcos.sdk.client.Client;
import org.fisco.bcos.sdk.client.protocol.response.BlockNumber;
import org.fisco.bcos.sdk.config.exceptions.ConfigException;
import org.fisco.bcos.sdk.crypto.keypair.CryptoKeyPair;
import org.fisco.bcos.sdk.model.TransactionReceipt;
import org.fisco.bcos.sdk.transaction.model.exception.ContractException;
import org.junit.Test;public class BcosSDKTest {// 获取配置文件路径//static String path1 = System.getProperty("user.dir");//static String configFile = path1 + "/conf.toml";static String configFile = "/home/ybx/fisco/console/conf/config.toml";//public final String configFile = BcosSDKTest.class.getClassLoader().getResource("config.toml").getPath();@Testpublic void getPath(){System.out.println(configFile);BcosSDK sdk = BcosSDK.build(configFile);System.out.println(sdk);}@Testpublic void testClient() throws ConfigException, ContractException {// 初始化BcosSDKBcosSDK sdk = BcosSDK.build(configFile);//System.out.println(sdk);// 为群组1初始化clientClient client = sdk.getClient(Integer.valueOf(1));// 获取群组1的块高BlockNumber blockNumber = client.getBlockNumber();System.out.println(blockNumber);// 向群组1部署HelloWorld合约CryptoKeyPair cryptoKeyPair = client.getCryptoSuite().getCryptoKeyPair();HelloWorld helloWorld = HelloWorld.deploy(client, cryptoKeyPair);// 调用HelloWorld合约的get接口String getValue = helloWorld.get();System.out.println("getValue的值是:"+getValue);// 调用HelloWorld合约的set接口TransactionReceipt receipt = helloWorld.set("Hello, fisco");}}二、注意的点
2.1 spring-boot版本不宜过高
- 高了会出错
<parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>2.4.2</version><relativePath/> <!-- lookup parent from repository --></parent>
2.2 读取项目根路径
static String path1 = System.getProperty("user.dir");
三、spring boot接口搭建
3.1 去掉数据库配置
- 不去掉数据库配置会报错
@SpringBootApplication(exclude= {DataSourceAutoConfiguration.class})
public class DemoApplication {public static void main(String[] args) {SpringApplication.run(DemoApplication.class, args);}
}
3.2 tomcat正常启动,localhost访问不到接口
- 原因:controller类和主类不在同一个包下
- 在main函数启动类上加注解：@SpringBootApplication(scanBasePackages = “com”) 问题即可解决。
3.3 lombok不起作用
- 添加lombok依赖后，还需要idea安装lombok插件
- 配置Annotation
