【中文标题】Spring Cloud 任务的 SimpleTaskConfiguration 和 Spring Batch 的 SimpleBatchConfiguration 防止 Spring Boot 自动配置 XA 事务【英文标题】:Spring cloud task's SimpleTaskConfiguration and spring batch's SimpleBatchConfiguration preventing spring boot auto configuration of XA transactions 【发布时间】:2016-11-21 13:56:46 【问题描述】:我正在尝试为配置了 Spring Boot 的 Spring Batch/Spring Cloud 任务应用程序配置 XA/分布式事务。
我添加了以下依赖项,希望依赖于spring boot自动配置:
compile("org.springframework.boot:spring-boot-starter-jta-atomikos")
但是,以下两个类会导致配置两个事务管理器:
org.springframework.cloud.task.configuration.SimpleTaskConfiguration
org.springframework.batch.core.configuration.annotation.SimpleBatchConfiguration
查看以下消息:
2016-07-18 21:46:19.952 INFO 18995 --- [ main] o.s.b.f.s.DefaultListableBeanFactory : Overriding bean definition for bean 'transactionManager' with a different definition: replacing [Root bean: class [null]; scope=; abstract=false; lazyInit=false; autowireMode=3; dependencyCheck=0; autowireCandidate=true; primary=false; factoryBeanName=org.springframework.batch.core.configuration.annotation.SimpleBatchConfiguration; factoryMethodName=transactionManager; initMethodName=null; destroyMethodName=(inferred); defined in class path resource [org/springframework/batch/core/configuration/annotation/SimpleBatchConfiguration.class]] with [Root bean: class [null]; scope=; abstract=false; lazyInit=false; autowireMode=3; dependencyCheck=0; autowireCandidate=true; primary=false; factoryBeanName=org.springframework.cloud.task.configuration.SimpleTaskConfiguration; factoryMethodName=transactionManager; initMethodName=null; destroyMethodName=(inferred); defined in org.springframework.cloud.task.configuration.SimpleTaskConfiguration]
然后因为配置了一个名为 transactionManager
的 PlatformTransactionManager
,所以我的 atomikos 自动配置没有被选中:
AtomikosJtaConfiguration did not match
- @ConditionalOnClass classes found: org.springframework.transaction.jta.JtaTransactionManager,com.atomikos.icatch.jta.UserTransactionManager (OnClassCondition)
- @ConditionalOnMissingBean (types: org.springframework.transaction.PlatformTransactionManager; SearchStrategy: all) found the following [transactionManager] (OnBeanCondition)
有人可以帮我防止上述两个类对 transactionManager
bean 的过度强制吗?
【问题讨论】:
您能否提供一个重现您的问题的可运行示例(build.gradle 和应用程序类)?因为,就像你之前的问题一样,没有它,我们所能做的就是把我们的猜测和假设扔给你,然后最终什么都不做。 我正在尝试组合一个示例应用程序来重现此内容。忍受我。 太棒了,谢谢,这应该很容易解决问题 这里是:github.com/balteo/atomikosIssue 唯一的要求是 Docker/Docker-compose 和 Java。 【参考方案1】:我遇到了同样的问题,我的解决方案是实现 BatchConfigurer(保留 @EnableBatchProcessing)并手动添加 atomikos bean。
工作配置:
@Configuration
@EnableBatchProcessing
public class JobConfig implements BatchConfigurer
@Autowired
private DataSource dataSource;
@Autowired
private JtaTransactionManager jtaTransactionManager;
// ... skipping some code
@Override
public JobRepository getJobRepository() throws Exception
JobRepositoryFactoryBean factory = new JobRepositoryFactoryBean();
factory.setDataSource(dataSource);
factory.setTransactionManager(jtaTransactionManager);
return factory.getObject();
@Override
public PlatformTransactionManager getTransactionManager() throws Exception
return jtaTransactionManager;
@Override
public JobLauncher getJobLauncher() throws Exception
SimpleJobLauncher launcher = new SimpleJobLauncher();
launcher.setJobRepository(getJobRepository());
launcher.setTaskExecutor(new SimpleAsyncTaskExecutor());
return launcher;
@Override
public JobExplorer getJobExplorer() throws Exception
JobExplorerFactoryBean jobExplorerFactoryBean = new JobExplorerFactoryBean();
jobExplorerFactoryBean.setDataSource(dataSource);
jobExplorerFactoryBean.afterPropertiesSet();
return jobExplorerFactoryBean.getObject();
AtomikosConfig:
@Configuration
public class AtomikosConfig extends AbstractJtaPlatform
@Bean(initMethod = "init", destroyMethod = "close")
@DependsOn("atomikosUserTransactionService")
public UserTransactionManager atomikosTransactionManager()
UserTransactionManager manager = new UserTransactionManager();
manager.setForceShutdown(false);
manager.setStartupTransactionService(false);
return manager;
@Bean(initMethod = "init", destroyMethod = "shutdownForce")
public UserTransactionServiceImp atomikosUserTransactionService()
Properties properties = new Properties();
return new UserTransactionServiceImp(properties);
@Bean
public UserTransactionImp atomikosUserTransaction() throws SystemException
UserTransactionImp transaction = new UserTransactionImp();
transaction.setTransactionTimeout(300);
return transaction;
@Primary
@Bean
public JtaTransactionManager jtaTransactionManager() throws Exception
JtaTransactionManager manager = new JtaTransactionManager();
manager.setTransactionManager(atomikosTransactionManager());
manager.setUserTransaction(atomikosUserTransaction());
manager.setAllowCustomIsolationLevels(true);
return manager;
@Bean
public ActiveMQXAConnectionFactory xaFactory()
ActiveMQXAConnectionFactory factory = new ActiveMQXAConnectionFactory();
factory.setBrokerURL("tcp://localhost:61616");
factory.setUserName("admin");
factory.setPassword("admin");
//factory.setTrustAllPackages(true);
factory.setTransactedIndividualAck(true);
return factory;
@Bean(initMethod = "init", destroyMethod = "close")
public AtomikosConnectionFactoryBean connectionFactory()
AtomikosConnectionFactoryBean factoryBean = new AtomikosConnectionFactoryBean();
factoryBean.setUniqueResourceName("amq1");
factoryBean.setXaConnectionFactory(xaFactory());
factoryBean.setMaxPoolSize(10);
return factoryBean;
@Bean
public AtomikosJtaPlatform springJtaPlatformAdapter() throws Exception
AtomikosJtaPlatform platform = new AtomikosJtaPlatform();
platform.setJtaTransactionManager(jtaTransactionManager());
platform.setTransactionManager(atomikosTransactionManager());
platform.setUserTransaction(atomikosUserTransaction());
return platform;
@Override
protected TransactionManager locateTransactionManager()
return atomikosTransactionManager();
@Override
protected UserTransaction locateUserTransaction()
return atomikosTransactionManager();
【讨论】:
【参考方案2】:看了你的例子后,我可以告诉你的是——没有办法让自动配置工作——即使你禁用了事务管理的自动配置,你确实尝试过,任务和批处理自动配置(由@EnableBatchProcessing
和@EnableTask
触发)仍将注册他们自己的事务管理器,从而阻止Atomikos 配置被触发。这样做的原因是因为@EnableBatchProcessing
包含BatchConfigurationSelector
配置类,而后者又包含SimpleBatchConfiguration
或ModularBatchConfiguration
,并且它们都将始终注册一个事务管理器——在任何一个bean 定义上都没有条件注释。 @EnableTask
做了一个非常相似的事情,只有SimpleTaskConfiguration
。
因此,我能看到的唯一解决方法是让您完全手动创建批处理和任务配置。
至于如何手动配置批处理和任务,我建议查看SimpleTaskConfiguration 和AbstractBatchConfiguration - 你可以看到所有需要注册的bean。
或者,您可以看到一个批处理示例on this Java Code Geeks page,您只需将 XML 配置转换为 Java 配置。
【讨论】:
这真的是唯一的方法吗?如果是这种情况,您能否提供有关如何创建批处理和任务配置的说明或文档指针? 是的,我在答案中添加了链接;基本上,只需参考 SimpleTaskConfiguration 和 AbstractBatchConfiguration 类,看看您需要手动定义哪些 bean。以上是关于Spring Cloud 任务的 SimpleTaskConfiguration 和 Spring Batch 的 SimpleBatchConfiguration 防止 Spring Boot 自动的主要内容,如果未能解决你的问题,请参考以下文章
