在Spring Boot/Spring批处理应用程序上配置Atomikos的问题

Question

我试图让原子与我的Spring Boot/Spring Batch应用程序一起工作。

以下是我代码的相关部分：

数据源配置：

@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自动配置依赖项：

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

我的application.properties代码：

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

这是自动配置报告：

   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)

我不知道为什么Atomikos没有自动配置。。。谁能帮忙吗？

编辑：我已经注释掉了JTA transactionManager bean，现在我得到了以下自动配置报告：

   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)

如何确保Atomikos事务管理器已启动？

编辑2：我排除了TransactionManager类，如下所示：

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

但是我似乎SimpleBatchConfiguration和SimpleTaskConfiguration仍然将几个TransactionManager类中的一个强加于我：

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]

导致AtomikosJtaConfiguration不匹配。。。

有人能建议一个最佳实践，以使原子自动配置工作？

您不需要添加原子或Bitronix即可为您的数据源指定PlatformTransactionManager。请参阅实体未持久化。是RepositoryItemWriter
