Encountered invalid @Scheduled method 'processNotifications': Cron expression must consist of 6 fields (found 1 in "#{@getConfigRetryValue}")
问题
我正在将 Ant 构建转换为 Gradle 构建。突然之间，之前从 XML 配置的 @schedule 不再起作用。我正在尝试初始化一个方法以从 XML 中获取值。我尝试了以下 XML 配置：
<interface name="appnotification">
<property name="retry_interval" value="0 0/5 * * * ?" /> <!-- 每 5 分钟一次 -->
</interface>
Java 文件如下：
@Component
@EnableScheduling
public class Task {
private static final String INTERFACE_NAME = "appnotification";
@Bean
public String getConfigRetryValue() {
Map interfaceProps = Config.getInterfaceProperties(INTERFACE_NAME);
return (String) interfaceProps.getOrDefault("retry_interval", DELAY_TIME_IN_MINS);
}
@Scheduled(cron = "#{@getConfigRetryValue}")
public void processNoti() {}
}
错误如下：
Caused by: org.springframework.beans.factory.BeanCreationException: 在 URL [jar:file:abc.jar!/abc/report/Task.class] 中定义的名为 'Task' 的 bean 创建错误：bean 初始化失败；嵌套异常是 java.lang.IllegalStateException: 遇到无效的 @Scheduled 方法 'processNotifications'：Cron 表达式必须包含 6 个字段（在 "#{@getConfigRetryValue}" 中找到 1 个字段）
