Question

我创建了一个Spring Boot 2（2.1.6.RELEASE）项目，该项目依赖于spring-boot-starter-data-jpa和spring spring-boot-starter-jta-bitronix，并为Mysql DB配置了XA数据源（ 8.0.16）。

应用程序属性文件（为与<>之间的占位符值相关而修剪）包含以下配置：

spring:
  datasource:
    url: jdbc:mysql://<host>:<port>/<dbName>
    username: <username>
    password: <password>
    driver-class-name: com.mysql.cj.jdbc.Driver
  jpa:
    database-platform: org.hibernate.dialect.MySQL8Dialect
    hibernate:
      ddl-auto: none
  jta:
    bitronix:
      properties:
        server-id: <serverid>

在启动spring boot应用程序时，我收到以下错误stacktrace：

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'entityManagerFactory' defined in class path resource [org/springframework/boot/autoconfigure/orm/jpa/HibernateJpaConfiguration.class]: Unsatisfied dependency expressed through method 'entityManagerFactory' parameter 0; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'entityManagerFactoryBuilder' defined in class path resource [org/springframework/boot/autoconfigure/orm/jpa/HibernateJpaConfiguration.class]: Unsatisfied dependency expressed through method 'entityManagerFactoryBuilder' parameter 0; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'jpaVendorAdapter' defined in class path resource [org/springframework/boot/autoconfigure/orm/jpa/HibernateJpaConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.orm.jpa.JpaVendorAdapter]: Factory method 'jpaVendorAdapter' threw exception; nested exception is bitronix.tm.resource.ResourceConfigurationException: cannot create JDBC datasource named dataSource

免责声明：我正在自我记录自己的问题，希望能够帮助其他人，因为令人惊讶的是这个问题/问题很难解决。

通过验证github https://github.com/bitronix/btm/issues/100上的bitronix问题跟踪器，即使问题已经关闭且没有直接答案，解决方案也不是很明显。

阅读https://github.com/bitronix/btm/wiki/FAQ上的bitronix常见问题解答，尽管与Oracle有关，但暗示了该问题，该问题指的是缺少用户特权。

进一步的调查导致获得关于特权https://dev.mysql.com/doc/refman/8.0/en/privileges-provided.html的MySQL 8文档页面，并在以下部分中突出显示了这一点。

在MySQL 8.0之前，任何用户都可以执行XA RECOVER语句来发现未完成的准备好的XA交易的XID值，可能导致用户提交或回滚XA事务除了启动它的人。 在MySQL 8.0中，XA RECOVER是仅允许具有XA_RECOVER_ADMIN特权的用户使用，预期仅授予有需要的管理用户 。例如，对于 XA应用程序（如果已崩溃且有必要查找）由应用程序启动的未完成交易，因此它们可以回滚。此特权要求可防止用户发现未完成的XA事务的XID值除了自己的。它不会影响正常的提交或回滚 XA交易，因为启动它的用户知道其XID。

因此，我通过MySQL中的以下命令为数据源用户添加了所需的特权（相应地替换用户名和主机部分）。

GRANT XA_RECOVER_ADMIN ON *.* TO 'username'@'%';
FLUSH PRIVILEGES;

进行此更改后，spring boot应用程序将启动，没有任何问题。

使用spring-boot和bitronix JTA管理器将XA数据源配置为mysql 8 DB失败，并出现SqlException XAERR_RMERR
