技术组件简介

JTA (Java Transaction API)：Java 提供的分布式事务处理标准接口
Atomikos：第三方实现的 JTA 事务管理器，支持跨多个数据源的分布式事务
MyBatis-Plus：基于 MyBatis 的增强工具，在本项目中用于数据访问层

添加 Maven 依赖

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-jta-atomikos</artifactId>
</dependency>

application.yml配置Atomikos数据源：

# Atomikos JTA配置
spring:
  jta:
    atomikos:
      datasource:
        custom:
          unique-resource-name: customDS
          xa-data-source-class-name: com.alibaba.druid.pool.xa.DruidXADataSource
          xa-properties:
            url: ${spring.datasource.custom.url}
            username: ${spring.datasource.custom.username}
            password: ${spring.datasource.custom.password}
          max-pool-size: 10
          min-pool-size: 2
          max-lifetime: 30000
          borrow-connection-timeout: 60
        ccod:
          unique-resource-name: ccodDS
          xa-data-source-class-name: com.alibaba.druid.pool.xa.DruidXADataSource
          xa-properties:
            url: ${spring.datasource.ccod.url}
            username: ${spring.datasource.ccod.username}
            password: ${spring.datasource.ccod.password}
          max-pool-size: 10
          min-pool-size: 2
          max-lifetime: 30000
          borrow-connection-timeout: 60

创建JTA配置类

JtaConfig 是一个基于 Atomikos 的分布式事务配置，支持 XA 数据源和 JTA 事务管理：

package com.hworld.custom.config;

import com.atomikos.icatch.jta.UserTransactionImp;
import com.atomikos.icatch.jta.UserTransactionManager;
import com.atomikos.jdbc.AtomikosDataSourceBean;
import com.baomidou.mybatisplus.spring.MybatisSqlSessionFactoryBean;
import java.util.HashMap;
import java.util.Map;
import javax.sql.DataSource;
import javax.transaction.TransactionManager;
import javax.transaction.UserTransaction;
import net.icsoc.ark.api.config.DynamicDataSource;
import net.icsoc.ark.api.constants.DataSourceType;
import org.apache.ibatis.session.SqlSessionFactory;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.DependsOn;
import org.springframework.context.annotation.Primary;
import org.springframework.core.env.Environment;
import org.springframework.core.io.support.PathMatchingResourcePatternResolver;
import org.springframework.transaction.PlatformTransactionManager;
import org.springframework.transaction.jta.JtaTransactionManager;

@Configuration
@MapperScan({"com.hworld.custom.dao.mapper.*"})
public class JtaConfig {

  private final Environment environment;

  public JtaConfig(Environment environment) {
    this.environment = environment;
  }

  /**
   * 共用MyBatis-Plus数据源
   *
   * @return
   */
  /*@Bean(name = "customXaDataSource")
  public DataSource customXaDataSource() {
    return createXaDataSource("spring.datasource.custom.url",
