使用的Shareding-JDBC包：

<!--引入 Sharding-JDBC，引入後，即可配置讀寫分離-->
		<dependency>
			<groupId>org.apache.shardingsphere</groupId>
			<artifactId>sharding-jdbc-spring-boot-starter</artifactId>
			<version>4.0.0-RC1</version>
		</dependency>
		<!-- 使用 Sharding-JDBC 下的 XA 事務 -->
		<!-- 因爲使用Sharding-JDBC配置讀寫分離數據源後，Spring自帶的事務會失效，需配合使用 -->
		<dependency>
			<groupId>org.apache.shardingsphere</groupId>
			<artifactId>sharding-transaction-xa-core</artifactId>
			<version>4.0.0-RC1</version>
		</dependency>

 復現方式

使用多線程批量插入數據的方式來複現：

AServiceImpl.a()-->BService.insert()

AServiceImpl.a():

@Override
    public boolean testMultiThreadTransaction() {
        boolean isOk=true;
        try {
            ThreadPoolExecutor threadPoolExecutor = new ThreadPoolExecutor(100, 300, 600,
                    TimeUnit.SECONDS, new ArrayBlockingQueue<>(300), new ThreadPoolExecutor.CallerRunsPolicy());
            for (int j = 0; j < 4000; j++) {
                System.out.println("執行第"+j);
                threadPoolExecutor.execute(()->{
                    try {
                        testTwoService.saveIn();
                    } catch (Exception e) {
                        log.error("testTransaction,for (int j = 0; j < 200; j++)異常，詳情：{}",e);
                        e.printStackTrace();
                    }
                });
            }
            threadPoolExecutor.shutdown();
            threadPoolExecutor.awaitTermination(Long.MAX_VALUE, TimeUnit.DAYS);
        } catch (Exception e) {
            log.error("testTransaction,異常，詳情：{}",e);
            e.printStackTrace();
        }
        return isOk;
    }

BService.insert():

@Override
    @Transactional(rollbackFor = Exception.class)
    public boolean saveIn(){
        boolean isOk=true;
        try{
            TransactionTypeHolder.set(TransactionType.XA);
            long flag = Math.round(Math.random()*100);
            testMapper.insertDataModel(UUIDUtils.getUUID(),flag);
        }catch (Exception ex){
            log.error("事務異常：{}",ex);
            ex.printStackTrace();
            isOk=false;
            System.out.println("異常："+ex.getMessage());
            TransactionAspectSupport.currentTransactionStatus().setRollbackOnly();
        }
        return isOk;

    }

解決方法

配置PlatformTransactionManager和JdbcTemplate

 

package net.cnki.author.remuneration.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.jdbc.core.JdbcTemplate;
import org.springframework.jdbc.datasource.DataSourceTransactionManager;
import org.springframework.transaction.PlatformTransactionManager;
import org.springframework.transaction.annotation.EnableTransactionManagement;

import javax.sql.DataSource;

@Configuration
@EnableTransactionManagement
public class TransactionConfiguration {

    @Bean
    public PlatformTransactionManager txManager(final DataSource dataSource) {
        return new DataSourceTransactionManager(dataSource);
    }

    @Bean
    public JdbcTemplate jdbcTemplate(final DataSource dataSource) {
        return new JdbcTemplate(dataSource);
    }
}
