带有两个数据源的Spring引导批处理导致javax.persistence.TransactionRequiredException:执行更新/删除查询

我有一个

springbootbatch

项目，有两个数据源，一个用于批处理表，一个用于业务表。从业务数据库读取数据时，它工作良好

我的配置看起来像

@Configuration
@EnableBatchProcessing
public class DataSourceConfiguration {

    @Bean
    @Primary
    @ConfigurationProperties(prefix = "spring.datasource")
    public DataSource dataSource() {
        return DataSourceBuilder.create().build();
    }

    @Bean
    @ConfigurationProperties(prefix = "spring.sybasedatasource")
    public DataSource sybaseDataSource() {
        return DataSourceBuilder.create().build();
    }

    @Bean
    BatchConfigurer batchConfigurer(DataSource dataSource) {
        return new DefaultBatchConfigurer(dataSource);
    }

    @Bean
    TaskConfigurer taskConfigurer(DataSource dataSource) {
        return new DefaultTaskConfigurer(dataSource);
    }
}

但是当我执行更新时

public interface DocumentRepository extends JpaRepository<DocumentDescriptor, Integer> {

    @Modifying
    @Query(value = "update document set process_status = :status where process_status = 10001 and document_id = :documentId")
    int updateDocumentStatus(Integer status, Integer documentId);
}

使用了

@Transaction（“tm2”）

，但例外情况仍然相同

你知道怎么做才能得到一笔合适的交易吗？

我用

@Configuration
@EnableTransactionManagement
@EnableJpaRepositories(
    basePackages = 
"...",
    entityManagerFactoryRef = "sybaseEntityManagerFactory",
    transactionManagerRef = "sybaseTransactionManager"
)
public class DataSourceConfiguration {

@Bean
@Primary
@ConfigurationProperties(prefix = "spring.datasource")
public DataSource dataSource() {
    return DataSourceBuilder.create().build();
}

@Bean
@ConfigurationProperties(prefix = "spring.sybasedatasource")
public DataSource sybaseDataSource() {
    return DataSourceBuilder.create().build();
}

@Bean
public LocalContainerEntityManagerFactoryBean sybaseEntityManagerFactory() {
    return new EntityManagerFactoryBuilder(new HibernateJpaVendorAdapter(), Collections.emptyMap(), null)
            .dataSource(sybaseDataSource())
            .packages("...")
            .persistenceUnit(DataSourceConfiguration.class.getSimpleName())
            .build();
}

@Bean
@Primary
public DataSourceTransactionManager postgresTransactionManager(@Qualifier("dataSource") DataSource datasource) {
    return new DataSourceTransactionManager(datasource);
}

@Bean
public JpaTransactionManager sybaseTransactionManager(EntityManagerFactory entityManagerFactory) {
    return new JpaTransactionManager(entityManagerFactory);
}
}

和

@Transactional（“sybaseTransactionManager”）

您如何设置crud回购的实体管理器？以某种方式检查事务是否被某些库禁用。我没有设置任何实体管理器，也没有扫描repo类。我使用的是

spring boot starter数据jpa

您应该设置entityManager并进行扫描，看看这样做后它是否正常工作。谢谢@sonus21。它把我推向了正确的方向。我用solution.done@MahmoudBenHassine更新了我的帖子

@Configuration
@EnableTransactionManagement
@EnableJpaRepositories(
    basePackages = 
"...",
    entityManagerFactoryRef = "sybaseEntityManagerFactory",
    transactionManagerRef = "sybaseTransactionManager"
)
public class DataSourceConfiguration {

@Bean
@Primary
@ConfigurationProperties(prefix = "spring.datasource")
public DataSource dataSource() {
    return DataSourceBuilder.create().build();
}

@Bean
@ConfigurationProperties(prefix = "spring.sybasedatasource")
public DataSource sybaseDataSource() {
    return DataSourceBuilder.create().build();
}

@Bean
public LocalContainerEntityManagerFactoryBean sybaseEntityManagerFactory() {
    return new EntityManagerFactoryBuilder(new HibernateJpaVendorAdapter(), Collections.emptyMap(), null)
            .dataSource(sybaseDataSource())
            .packages("...")
            .persistenceUnit(DataSourceConfiguration.class.getSimpleName())
            .build();
}

@Bean
@Primary
public DataSourceTransactionManager postgresTransactionManager(@Qualifier("dataSource") DataSource datasource) {
    return new DataSourceTransactionManager(datasource);
}

@Bean
public JpaTransactionManager sybaseTransactionManager(EntityManagerFactory entityManagerFactory) {
    return new JpaTransactionManager(entityManagerFactory);
}
}
