Spring 3.2"@Scheduled"注释的异常处理

如果要使用Java Config,则需要创建实现SchedulingConfigurer的配置

@EnableScheduling
@Configuration
class SchedulingConfiguration implements SchedulingConfigurer {
    private final Logger logger = LoggerFactory.getLogger(getClass());
    private final ThreadPoolTaskScheduler taskScheduler;

    SchedulingConfiguration() {
        taskScheduler = new ThreadPoolTaskScheduler();
        taskScheduler.setErrorHandler(t -> logger.error("Exception in @Scheduled task. ", t));
        taskScheduler.setThreadNamePrefix("@scheduled-");

        taskScheduler.initialize();
    }

    @Override
    public void configureTasks(ScheduledTaskRegistrar taskRegistrar) {
        taskRegistrar.setScheduler(taskScheduler);
    }
}

您可以根据需要修改错误处理程序.这里我只记录一条消息.

别忘了调用taskScheduler.initialize(); .没有它你会得到:

java.lang.IllegalStateException: ThreadPoolTaskScheduler not initialized
