Springboot整合jta+atomikos解决单jvm多数据源事务问题

1、依赖

	org.springframework.boot
	spring-boot-starter-jta-atomikos

2、配置

@Configuration
// basePackages 最好分开配置 如果放在同一个文件夹可能会报错
@MapperScan(basePackages = "com.wangcj.test01", sqlSessionTemplateRef = "testSqlSessionTemplate")
public class MyBatisConfig1 {

	// 配置数据源
	@Primary
	@Bean(name = "testDataSource")
	public DataSource testDataSource(DBConfig1 testConfig) throws SQLException {
		MysqlXADataSource mysqlXaDataSource = new MysqlXADataSource();
		mysqlXaDataSource.setUrl(testConfig.getUrl());
		mysqlXaDataSource.setPinGlobalTxToPhysicalConnection(true);
		mysqlXaDataSource.setPassword(testConfig.getPassword());
		mysqlXaDataSource.setUser(testConfig.getUsername());
		mysqlXaDataSource.setPinGlobalTxToPhysicalConnection(true);

		AtomikosDataSourceBean xaDataSource = new AtomikosDataSourceBean();
		xaDataSource.setXaDataSource(mysqlXaDataSource);
		xaDataSource.setUniqueResourceName("testDataSource");

		xaDataSource.setMinPoolSize(testConfig.getMinPoolSize());
		xaDataSource.setMaxPoolSize(testConfig.getMaxPoolSize());
		xaDataSource.setMaxLifetime(testConfig.getMaxLifetime());
		xaDataSource.setBorrowConnectionTimeout(testConfig.getBorrowConnectionTimeout());
		xaDataSource.setLoginTimeout(testConfig.getLoginTimeout());
		xaDataSource.setMaintenanceInterval(testConfig.getMaintenanceInterval());
		xaDataSource.setMaxIdleTime(testConfig.getMaxIdleTime());
		xaDataSource.setTestQuery(testConfig.getTestQuery());
		return xaDataSource;
	}

	@Bean(name = "testSqlSessionFactory")
	public SqlSessionFactory testSqlSessionFactory(@Qualifier("testDataSource") DataSource dataSource)
			throws Exception {
		SqlSessionFactoryBean bean = new SqlSessionFactoryBean();
		bean.setDataSource(dataSource);
		return bean.getObject();
	}

	@Bean(name = "testSqlSessionTemplate")
	public SqlSessionTemplate testSqlSessionTemplate(
			@Qualifier("testSqlSessionFactory") SqlSessionFactory sqlSessionFactory) throws Exception {
		return new SqlSessionTemplate(sqlSessionFactory);
	}
}
