SpringBoot集成Atomikos提示transaction manager not running_spring

Atomikos TransactionsEssentials 是一个为Java平台提供增值服务的并且开源类事务管理器，以下是包括在这个开源版本中的一些功能：

l 全面崩溃 / 重启恢复

l 兼容标准的SUN公司JTA API

l 嵌套事务

l 为XA和非XA提供内置的JDBC适配器

注释：XA：XA协议由Tuxedo首先提出的，并交给X/Open组织，作为资源管理器（数据库）与事务管理器的接口标准。Oracle、Informix、DB2和Sybase等各大数据库厂家都提供对XA的支持。XA协议采用两阶段提交方式来管理分布式事务。XA接口提供资源管理器与事务管理器之间进行通信的标准接口。XA协议包括两套函数，以xa_开头的及以ax_开头的。

SpringBoot集成Atomikos提示transaction manager not running_springboot事务_02

使用SpringBoot集成Atomikos时出现一个问题，提示大量Warn：

15:03:01.118 [restartedMain] WARN  c.a.j.AtomikosConnectionProxy - [logWarning,24] - 
atomikos connection proxy for com.mysql.cj.jdbc.ConnectionImpl@3b8b4cb6: WARNING: transaction manager not running?
15:03:01.150 [restartedMain] WARN  c.a.j.AtomikosConnectionProxy - [logWarning,24] -

atomikos connection proxy for com.mysql.cj.jdbc.ConnectionImpl@3b8b4cb6: WARNING: transaction manager not running?
......

经过验证，多数据源事物正常使用，但是大量提示WARN，让我很不舒服。

它有个外国github的说法是这样的

SpringBoot集成Atomikos提示transaction manager not running_多数据源_03

但是我感觉不可能这么多年了还有这样的问题，最终找到答案，是因为我们在配置数据源时没有显示指定分布式事务管理器

如下代码，JTA 事务配置：

import javax.transaction.TransactionManager;
import javax.transaction.UserTransaction;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.DependsOn;
import org.springframework.transaction.PlatformTransactionManager;
import org.springframework.transaction.jta.JtaTransactionManager;
import com.atomikos.icatch.jta.UserTransactionImp;
import com.atomikos.icatch.jta.UserTransactionManager;

/**
 * JTA 事务配置
 */
@Configuration
public class AtomikosConfig {
    @Bean(name = "userTransaction")
    public UserTransaction userTransaction() throws Throwable {
        UserTransactionImp userTransactionImp = new UserTransactionImp();
        userTransactionImp.setTransactionTimeout(10000);
        return userTransactionImp;
    }

    @Bean(name = "atomikosTransactionManager", initMethod = "init", destroyMethod = "close")
    public TransactionManager atomikosTransactionManager() throws Throwable {
        UserTransactionManager userTransactionManager = new UserTransactionManager();
        userTransactionManager.setForceShutdown(false);
        return userTransactionManager;
    }

    @Bean(name = "transactionManager")
    @DependsOn({ "userTransaction", "atomikosTransactionManager" })
    public PlatformTransactionManager transactionManager() throws Throwable {
        UserTransaction userTransaction = userTransaction();
        TransactionManager atomikosTransactionManager = atomikosTransactionManager();
        return new JtaTransactionManager(userTransaction, atomikosTransactionManager);
    }
}

因为使用的是Druid，配置Druid多数据源：
