在Spring Boot/Spring批處理應用程序上配置Atomikos問題

Question

我想讓Atomikos與我的Spring Boot/Spring批處理應用程序一起工作。

這裏是我的代碼的相關部分：

數據源配置：

@Configuration 
public class DatasourceConfiguration extends AbstractCloudConfig { 

    @Bean 
    @Qualifier("batch_database") 
    public DataSource batchDatasource() { 
     return connectionFactory().dataSource("batch_database"); 
    } 

    @Bean 
    public PlatformTransactionManager transactionManager(){ 
     return new JtaTransactionManager(); 
    } 

    @Bean 
    public TaskConfigurer configurer(){ 
     return new DefaultTaskConfigurer(batchDatasource()); 
    } 
} 

Atomikos公司自動配置依賴性：

compile("org.springframework.boot:spring-boot-starter-jta-atomikos") 

我application.properties：

spring.datasource.application.driver-class-name=org.postgresql.xa.PGXADataSource 
spring.datasource.batch.driver-class-name=org.postgresql.xa.PGXADataSource 

下面是自動配置報告：

DataSourceTransactionManagerAutoConfiguration matched 
     - @ConditionalOnClass classes found: org.springframework.jdbc.core.JdbcTemplate,org.springframework.transaction.PlatformTransactionManager (OnClassCondition) 

    DataSourceTransactionManagerAutoConfiguration.DataSourceTransactionManagerConfiguration matched 
     - @ConditionalOnBean (types: javax.sql.DataSource; SearchStrategy: all) found the following [batchDatasource, applicationDatasource, batch_database, application_database, database] (OnBeanCondition) 

    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) 

    AtomikosJtaConfiguration.AtomikosJtaJmsConfiguration did not match 
     - required @ConditionalOnClass classes not found: javax.jms.Message (OnClassCondition) 
     - Ancestor 'org.springframework.boot.autoconfigure.transaction.jta.AtomikosJtaConfiguration' did not match (ConditionEvaluationReport.AncestorsMatchedCondition) 

我不知道爲什麼Atomikos公司是不是自動配置...任何人都可以請幫助？

編輯：我註釋掉中的JTA TransactionManager豆，我現在得到以下自動配置報告：

DataSourceTransactionManagerAutoConfiguration matched 
     - @ConditionalOnClass classes found: org.springframework.jdbc.core.JdbcTemplate,org.springframework.transaction.PlatformTransactionManager (OnClassCondition) 

    DataSourceTransactionManagerAutoConfiguration.DataSourceTransactionManagerConfiguration matched 
      - @ConditionalOnBean (types: javax.sql.DataSource; SearchStrategy: all) found the following [batchDatasource, applicationDatasource, batch_database, application_database, database] (OnBeanCondition) 

    TransactionAutoConfiguration matched 
     - @ConditionalOnClass classes found: org.springframework.transaction.support.TransactionTemplate,org.springframework.transaction.PlatformTransactionManager (OnClassCondition) 
     - @ConditionalOnSingleCandidate (types: org.springframework.transaction.PlatformTransactionManager; SearchStrategy: all) found a primary candidate amongst the following [transactionManager] (OnBeanCondition) 

    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) 

    AtomikosJtaConfiguration.AtomikosJtaJmsConfiguration did not match 
     - required @ConditionalOnClass classes not found: javax.jms.Message (OnClassCondition) 
     - Ancestor 'org.springframework.boot.autoconfigure.transaction.jta.AtomikosJtaConfiguration' did not match (ConditionEvaluationReport.AncestorsMatchedCondition) 

我怎樣才能確保Atomikos公司事務管理器拾取？

編輯2：我已經排除TransactionManager類如下：

@EnableAutoConfiguration(exclude = {DataSourceTransactionManagerAutoConfiguration.class, TransactionAutoConfiguration.class}) 

，但我似乎SimpleBatchConfiguration和SimpleTaskConfiguration仍然迫使一些TransactionManager類（ES）的一個對我道：

2016-07-12 11:27:57.846 INFO 4851 --- [   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] 

導致AtomikosJtaConfiguration不匹配...

有人可以建議一個最佳實踐，以使Atomikos自動配置工作嗎？

您不需要添加Atomikos或Bitronix來爲您的數據源指定PlatformTransactionManager。請參閱Entities not persisting. Are RepositoryItemWriter & SimpleJpaWriter thread-safe?。
