spring 启动 atomikos 多数据源连接池耗尽 jdbc
spring boot atomikos multiple datasource connection pool exhausted plain jdbc
我有一个 Spring 引导应用程序，它使用 Atomikos 进行 JTA 托管事务。它使用多个数据源连接多个数据库。
第一个请求 returns 预期结果，但第二个请求失败并出现 'Pool exhausted' 异常。
我用普通 JDBC 和 JdbcTemplate 尝试过，但没有结果。是一样的。
这是我的 Spring 引导版本 1.5 的代码。8.RELEASE
@SpringBootApplication
@EnableAutoConfiguration(exclude = {
DataSourceAutoConfiguration.class,
HibernateJpaAutoConfiguration.class, //if you are using Hibernate
DataSourceTransactionManagerAutoConfiguration.class
})
@EnableTransactionManagement
public class App {
public static void main(String[] arg) {
SpringApplication.run(App.class, arg);
}
}
第一种方法'index()'是普通的JDBC。第二个 'a()' 是 JdbcTemplate。

我自己找到了解决方案。
Atomikos 事务管理器只是有一个错误 - 我切换到 Bitronix，现在一切正常。
这是 4.0.4 中的已知问题 - 将在 TransactionsEssentials 的 4.0.5 中修复。
我有一个 Spring 引导应用程序，它使用 Atomikos 进行 JTA 托管事务。它使用多个数据源连接多个数据库。

Atomikos 事务管理器只是有一个错误 - 我切换到 Bitronix，现在一切正常。
这是 4.0.4 中的已知问题 - 将在 TransactionsEssentials 的 4.0.5 中修复。
