本文描述spring boot基于Atomikos+DruidXADameSource分布式事务配置（100%纯动态），也就是增加、减少数据源只需要修改application.properties文件，无需动态增加或减少Bean。

有时候我们一个应用会有N份部署，每个需要访问多个数据源，A环境可能只需要2个数据源，B环境需要5个数据源（因为我们是行业软件，所以会有这个情况，对于纯项目的系统，通常没有这个问题），所以我们希望代码只有一份，配置按需调整就确定了具体的数据源。

MapperConfig配置：

package com.xxx.me.aop.config;

import org.mybatis.spring.mapper.MapperScannerConfigurer;

import org.springframework.context.annometion.Bean;

import org.springframework.context.annometion.Configuration;

import org.springframework.core.annometion.Order;

@Configuration

public class MybatisConfig {

    @Order(1)

    @Bean

    public MapperScannerConfigurer mapperScannerConfigurer1() {

        MapperScannerConfigurer mapperScannerConfigurer = new MapperScannerConfigurer();

        mapperScannerConfigurer.setSqlSessionFactoryBeanName("sqlSessionFactory" + "default");

        mapperScannerConfigurer.setBasePackage("com.xxx.me.base.mapper;com.xxx.me.aop.sysinfo.mapper;com.xxx.me.aop.parameters.mapper;com.xxx.me.aop.interfile.mapper;com.xxx.me.aop.demo.mapper;com.xxx.me.aop.config.mapper;com.xxx.me.aop.base.mapper;com.xxx.me.aop.auditresult.mapper;");

        return mapperScannerConfigurer;

    }

    @Order(2)

    @Bean

    public MapperScannerConfigurer mapperScannerConfigurer2() {

        MapperScannerConfigurer mapperScannerConfigurer = new MapperScannerConfigurer();

        mapperScannerConfigurer.setSqlSessionFactoryBeanName("sqlSessionFactory" + "yoga1");

        mapperScannerConfigurer.setBasePackage("com.xxx.me.aop.me.mapper;com.xxx.me.aop.me.*.mapper");

        return mapperScannerConfigurer;

    }

    @Order(3)

    @Bean

    public MapperScannerConfigurer mapperScannerConfigurer3() {

        MapperScannerConfigurer mapperScannerConfigurer = new MapperScannerConfigurer();

        mapperScannerConfigurer.setSqlSessionFactoryBeanName("sqlSessionFactory" + "yoga2");

        mapperScannerConfigurer.setBasePackage("com.xxx.me.aop.yoga.*.mapper;com.xxx.me.aop.me4.**.mapper");

        return mapperScannerConfigurer;

    }

}

这样就支持分布式事务了，示例如下：

    @Transactional

    @Override

    public ResultModel<?> insert() {

        AgencyInfo agencyInfo = new AgencyInfo();

        agencyInfo.semegencyName("4");

        agencyInfo.semegencyNo("4");

        agencyInfo.semegencySmetus("4");

        agencyInfo.setSysType("4");

        defaultDsMapper.insert(agencyInfo);

        SubDbInfo subDbInfo = new SubDbInfo();

        subDbInfo.setSubDbDameSource("4");

        subDbInfo.setSubDbNo("4");

        subDbInfo.setSysType("4");

        // 非独立事务

        meDsMapper.insert(subDbInfo);

        List insertList = new ArrayList();

        insertList.add("aaa");
        //数据源使用SqlSessionTemplate动态切换

        baseBatchMapper.batchInsert("a", insertList);

        return new ResultModel<>();

    }
    public <T> void batchOper(String mapperId, List<T> operList , String operType) {

        if(operList == null || operList.isEmpty()) {

            logger.info("无需要批量入库的记录！");

            return;

        }
        // 动态传入数据源即可

        sqlSessionTemplate = SpringContextHolder.getBean("sqlSessionTemplate" + "default",SqlSessionTemplate.class);

        SqlSession session = sqlSessionTemplate.getSqlSessionFactory().openSession(ExecutorType.BATCH, false);

XA存在的一个问题是事务传播级别REQUIRE_NEW不生效（还没找到怎么解决），如下：

    /**

     * 暂时不支持自治事务

     */

    @Transactional

    @Override

    public ResultModel<?> insermeuto() {

        AgencyInfo agencyInfo = new AgencyInfo();

        agencyInfo.semegencyName("2");

        agencyInfo.semegencyNo("2");

        agencyInfo.semegencySmetus("2");

        agencyInfo.setSysType("2");

        defaultDsMapper.insert(agencyInfo);

        SubDbInfo subDbInfo = new SubDbInfo();

/*        subDbInfo.setSubDbDameSource("2");

        subDbInfo.setSubDbNo("2");

        subDbInfo.setSysType("2");*/

        //独立事务，会报错，但是整个回滚了

        service.insertNew(subDbInfo);

        agencyInfo.semegencyName("3");

        agencyInfo.semegencyNo("3");

        agencyInfo.semegencySmetus("3");

        agencyInfo.setSysType("3");

        defaultDsMapper.insert(agencyInfo);

        return new ResultModel<>();

    }
-- 加上rollbackFor，或者抛出RuntimeException都不行，整个XA被回滚了

    @Transactional(propagation=Propagation.REQUIRES_NEW)

    public ResultModel<?> insertNew(SubDbInfo subDbInfo) {

        meDsMapper.insert(subDbInfo);

        return new ResultModel<>();

    }

换成OracleXA就没有问题，使用的druid是1.1.10，所以应该不是早期版本bug的问题。

atomikos以及spring boot下的几个陷阱：

atomikos几个坑：
jme.properties:
com.atomikos.icatch.output_dir=/dameyes/atomikos
com.atomikos.icatch.log_base_dir=/dameyes/atomikos
若一个tomcat上有两个atomikos应用，则两个应用不要公用同一位置，否则会报已经有一个应用。

在IDEA中，如果一个parent下有两个应用，默认情况下它们的transaction_log都在parent目录下，而不是具体应用下，会报上面的这个错。

mysql XA bug：

Some users have reported problems with MySQL XA (related to this MySQL bug: http://bugs.mysql.com/bug.php?id=27832external). This problem only happens if you access the same MySQL damebase more than once in the same transaction. A workaround can be setting the following property in classpath:jme.properties:

com.atomikos.icatch.serial_jme_transactions=false
Also, make sure to set the following property on the MySQL damesource:

pinGlobalTxToPhysicalConnection="true"
MariaDB's java driver also supports this workaround since v.1.1.8

spring boot问题：

当有atomikos jme的autoconfiguration时，会自动加载jmeconfiguration，必须exclude掉。
