运行单作业,SERIALIZED隔离级别时,无法序列化对此事务的访问

如何为整个批次设置一个隔离级别?

实际上,我在设置IsolationLevel,如下所示:

*更新配置类*

@Configuration

@EnableBatchProcessing

public class ApplicationBatchConfig {



                private static final Logger LOGGER = LoggerFactory.getLogger(ApplicationBatchConfig.class);



                @Autowired

                private Environment environment;



                /**

                */
                @Bean(name = "dataSource")

                @ConfigurationProperties(prefix = "spring.datasource")

                public DataSource dataSource() {
                  return DataSourceBuilder.create().build();
                }


                /**

                */

                @Bean(name = "jobRepository")

                public JobRepository jobRepository(final DataSource dataSource, final PlatformTransactionManager transactionManager) throws Exception {

                               final JobRepositoryFactoryBean rc = new JobRepositoryFactoryBean();

                               rc.setDatabaseType("ORACLE");

                               rc.setDataSource(dataSource);

                               rc.setTransactionManager(transactionManager);

                               rc.setIsolationLevelForCreate("ISOLATION_READ_COMMITTED");

                               String location = System.getProperty("ext.properties.dir");

                               if (!StringUtils.hasText(location)) {

                                               }

                                               ppc.setLocations(new Resource[] { new ClassPathResource(propertiesBatchLocation), new ClassPathResource(propertiesLogLocation),

                                                                              new ClassPathResource(propertiesAppliLocation) });

                                               ppc.setLocations(new Resource[] { new FileSystemResource(propertiesBatchLocation), new FileSystemResource(propertiesLogLocation),

                                                                              new FileSystemResource(propertiesAppliLocation) });



                               }

                               ppc.setIgnoreResourceNotFound(true);

                               ppc.setFileEncoding(IConstantBatch.PROPERTIES_ENCODING);

                               ppc.setOrder(1);

                               ppc.setIgnoreUnresolvablePlaceholders(true);

                               LOGGER.info(" repertoire de configuration batch utilisé : {}", propertiesLocation);



                               return ppc;



                }
}

但是在运行期间,当Spring Batch要使用其技术参数表时,隔离级别从2切换到8-请参见下面的日志

这会触发“无法序列化”异常。

答案 0 :(得分:2)

在当前配置下,您在Spring应用程序上下文中声明的JobRepository类型的Bean将不是Spring Batch所选择的。实际上,它是将要使用的默认值(由@EnableBatchProcessing创建),默认情况下使用SERIALIZABLE隔离级别。

如参考文档的Configuring a JobRepository部分中所述,您需要实现BatchConfigurer接口并在您的配置中提供该类型的Bean,或使您的配置类扩展{{1} }并覆盖DefaultBatchConfigurer
