我们尝试开发cron批处理。我配置了一个@schedulerlock anotion,但这些都不起作用。此代码可能用于多个节点。我在github中读到,@schedulerlock可以与这些实现一起工作,但不能工作。我也试过了,但也没用。我需要帮助来运行这些代码,因为我不知道代码中的失败是什么。谢谢!
@SpringBootApplication
@EnableAutoConfiguration
@EnableCaching
public class AppExportacionDatos {
public static void main(String[] args) {
SpringApplication.run(AppExportacionDatos.class, args);
}
}
@Configuration
@EnableScheduling
@EnableSchedulerLock(defaultLockAtMostFor = "540m")
public class CommonConfig {
@Bean
public LockProvider lockProvider(DataSource dataSource) {
return new JdbcTemplateLockProvider(
JdbcTemplateLockProvider.Configuration.builder()
.withJdbcTemplate(new JdbcTemplate(dataSource))
.usingDbTime() // Works on Postgres, MySQL, MariaDb, MS SQL, Oracle, DB2, HSQL and H2
.build()
);
}
@Bean
public MessageSource messageSource() {
ReloadableResourceBundleMessageSource messageSource = new ReloadableResourceBundleMessageSource();
messageSource.setBasename("classpath:i18n/messages");
messageSource.setDefaultEncoding("ISO-8859-1");
return messageSource;
}
@Bean
public LocalValidatorFactoryBean getValidator() {
LocalValidatorFactoryBean bean = new LocalValidatorFactoryBean();
bean.setValidationMessageSource(messageSource());
return bean;
