Azure Functions TimerTrigger 计划在特定时间不起作用

Question

我正在使用 TimerTrigger 使用 Azure Functions，并且遇到了一个问题：间隔计划运行良好（例如，每分钟、每 5 分钟），但特定计划未按预期触发。

@FunctionName("MyFunction")
    public void run(
        @TimerTrigger(name = "timerInfo", schedule = "0 * * * * *") // Executes every minute
        // Cron expression for every hour
            String timerInfo, 
            final ExecutionContext context) {

        context.getLogger().info("Java Timer trigger function executed at: " + Instant.now());
    // Function logic...
}

我尝试使用不同的 UTC 格式为 TimerTrigger 设置各种时间表，例如：

0 30 5 * * * (expected to trigger at 5:30 AM UTC daily)
0 15 12 * * * (expected to trigger at 12:15 PM UTC daily)

运行这些计划后，该函数成功执行，终端中没有任何错误。但是，我注意到没有任何日志表明计时器触发功能已启动，例如“计时器触发功能开始于：...”。

Answer 1

我已经创建了一个 Java 计时器触发器 azure 函数，并且能够按预期在指定的时间表触发该函数。

代码片段：

 @FunctionName("TimerTriggerJava1")
    public void run(
        @TimerTrigger(name = "timerInfo", schedule = "<cronexpression>") String timerInfo,
        final ExecutionContext context
    ) {
        context.getLogger().info("Java Timer trigger function executed at: " + LocalDateTime.now());
    }

修改函数代码中的CRON表达式后运行

mvn clean install

，然后运行

mvn azure-functions:run

。
