SpringBoot使用GTS的示例详解 SpringBoot使用GTS的示例详解

1. 依赖类库txc-client.jar, txt-client-spring-cloud-2.0.1.jar
【SpringBoot使用GTS的示例详解】2. 使用TxcDataSource代理源数据源【注意：dbcp2.BasicDataSource不支持，可以使用DruidDataSource】
3. 添加自动配置类文件

package com.bodytrack.restapi; import com.taobao.txc.client.aop.TxcTransactionScaner; import com.taobao.txc.client.boot.TxcSpringBootProperties; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.boot.autoconfigure.condition.ConditionalOnProperty; import org.springframework.boot.context.properties.EnableConfigurationProperties; import org.springframework.context.ApplicationContext; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.context.annotation.DependsOn; @Configuration@EnableConfigurationProperties({TxcSpringBootProperties.class})public class TxcSpringBootAutoConfiguration {@Autowiredprivate TxcSpringBootProperties txcSpringBootProperties; @Autowiredprivate ApplicationContext applicationContext; private static boolean isEmpty(String str) {return str == null || str.length() == 0; } @Bean(name = "txcScanner")@ConditionalOnProperty(prefix = "spring.boot.txc",name = {"txcServerGroup"})//定义声明式事务，要想让事务annotation感知的话，要在这里定义一下public TxcTransactionScaner txcTransactionScaner() {String appName = this.txcSpringBootProperties.getTxcAppName() == null ? this.applicationContext.getEnvironment().getProperty("spring.application.name") : this.txcSpringBootProperties.getTxcAppName(); String txServiceGroup = this.txcSpringBootProperties.getTxcServerGroup(); int mode = this.txcSpringBootProperties.getMode() == 0 ? 1 : this.txcSpringBootProperties.getMode(); TxcTransactionScaner txcTransactionScanner = new TxcTransactionScaner(appName, txServiceGroup, mode, this.txcSpringBootProperties.getUrl()); if (!isEmpty(this.txcSpringBootProperties.getAccessKey())) {txcTransactionScanner.setAccessKey(this.txcSpringBootProperties.getAccessKey()); } if (!isEmpty(this.txcSpringBootProperties.getSecretKey())) {txcTransactionScanner.setSecretKey(this.txcSpringBootProperties.getSecretKey()); } return txcTransactionScanner; }}

4. 添加GTS配置

spring:boot:txc:txcAppName: demotxcServerGroup: txc_test_public.1129361738553704.QD #公网测试的专用事务分组url: https://test-cs-gts.aliyuncs.com #公网测试urlaccessKey: xxx #非测试时需提供secretKey: xxxx #非测试时需提供

5. 发送rest请求时，请求添加header(TXC_XID,BEGIN_COUNT,COMMIT_COUNT)

public String callTestTxc() {HttpHeaders requestHeaders = new HttpHeaders(); requestHeaders.set("TXC_XID", String.valueOf(TxcContext.getCurrentXid())); requestHeaders.set("BEGIN_COUNT", String.valueOf(TxcContext.getBeginCount())); requestHeaders.set("COMMIT_COUNT", String.valueOf(TxcContext.getCommitCount())); HttpEntity entity = new HttpEntity<>("parameters", requestHeaders); String restUrl = String.format("%s/api/scoreService/testTxc", "http://10.0.0.5:8762"); ResponseEntity restData = https://www.it610.com/article/restTemplate.exchange(restUrl, HttpMethod.GET, entity,String.class); return restData.toString(); }

6. 发起全局事务使用注解@TxcTransaction
