This article mainly shows you "SpringBoot how to use GTS", the content is easy to understand, clear, hope to help you solve your doubts, the following let the editor lead you to study and learn "SpringBoot how to use GTS" this article.

1. Dependent class libraries txc-client.jar, txt-client-spring-cloud-2.0.1.jar

two。 Use TxcDataSource proxy source data source [Note: dbcp2.BasicDataSource does not support it, you can use DruidDataSource]

3. Add automatic configuration class file

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 {@ Autowired private TxcSpringBootProperties txcSpringBootProperties; @ Autowired private ApplicationContext applicationContext; private static boolean isEmpty (String str) {return str = = null | | str.length () = = 0 } @ Bean (name = "txcScanner") @ ConditionalOnProperty (prefix = "spring.boot.txc", name = {"txcServerGroup"}) / / define declarative transactions. To make the transaction annotation aware, define 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. Add GTS configuration

Spring: boot: txc: txcAppName: demo txcServerGroup: txc_test_public.1129361738553704.QD # Private transaction packet for public network testing url: https://test-cs-gts.aliyuncs.com # Public network test url accessKey: xxx # provide secretKey: xxxx # for non-testing

5. When sending a rest request, request to add 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 = restTemplate.exchange (restUrl, HttpMethod.GET, entity, String.class); return restData.toString ();}

6. Initiating a global transaction using the annotation @ TxcTransaction
