Question

我的服务方法是用Transnational（org.springframework.transaction.annotation）注解的但是在对表 Persons 进行更新时仍然会发生“TransactionRequiredException”。同一张桌子上的选择工作正常。

@Transactional
public String myMethod(String contractNo){
    myRepository.resetValues(contractNo);
}

@Repository
public interface MyRepository extends JpaRepository<Persons, Long> {

    @Modifying
    @Query(value = "UPDATE PERSONS SET status = 0 WHERE LOGIN_NAME like :contractNo", nativeQuery = true)
    void resetValues(@Param("contractNo") String contractNo);
}



@Configuration
@EnableTransactionManagement
@EnableJpaRepositories(
        entityManagerFactoryRef = "entityManagerFactory",
        transactionManagerRef = "transactionManager",
        basePackages = { "com.mypackage.repositories" }
)
public class EBankingDBConfig {

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

    @Bean(name = "entityManagerFactory")
    public LocalContainerEntityManagerFactoryBean entityManagerFactory(
            EntityManagerFactoryBuilder builder,
            @Qualifier("dataSource") DataSource dataSource) {
        return builder.dataSource(dataSource)
                        .packages("com.mypackage.model")
                        .persistenceUnit("myPersistenceUnit")
                        .build();
    }

    @Bean(name = "transactionManager")
    public PlatformTransactionManager transactionManager(
            @Qualifier("entityManagerFactory") EntityManagerFactory
                    entityManagerFactory) {
        return new JpaTransactionManager(entityManagerFactory);
    }
}

因为项目中定义了多个TransactionManagers bean，所以非主TransactionaManagers的事务必须用它们的名字来注释。例如，在我上面的配置中，TransactionManager 名称被定义为“transactionManager”。因此，方法上的事务注释应该看起来像这样：@Transactional("transactionManager")

Spring-boot TransactionRequiredException：执行更新/删除查询
