Java Camel：从同一目录读取和写入

我有一条骆驼路线：

final String URI_FILE = "file:{{PATH}}";
final String POOLER = "&scheduler=quartz2&scheduler.cron=0+0/10+*+*+*+?";

from(URI_FILE + POOLER)
.pollEnrich().simple("{{URL_CHECKER}}",String.class).aggregationStrategy(new myEstratey())
.choice()
    .when(exchangeProperty("CONTINUE").isEqualTo(true))
        .log("Condition was met")
        .to(URI_DIRECT) //To another route
     .endChoice()
     .otherwise()
        .log("I'll try again later")
        .to(URI_FILE) 
.endChoice();

我想从路径中读取文件，每次10分钟，然后使用轮询器检查条件。如果满足条件，则路线将继续。在另一种情况下，我希望将文件返回到同一目录（路径）

此路由工作正常，甚至会显示日志消息“我稍后再试”，但之后，该文件将消失，并且不会返回到路径

发生了什么事？骆驼是不允许这样做的

谢谢

该文件很可能在目标目录中被覆盖，但完成后，它将被移动到

.camel

目录

final String URI_FILE = "file:{{PATH}}";
final String POOLER = "&scheduler=quartz2&scheduler.cron=0+0/10+*+*+*+?";

from(URI_FILE + POOLER)
.pollEnrich().simple("{{URL_CHECKER}}",String.class).aggregationStrategy(new myEstratey())
.choice()
    .when(exchangeProperty("CONTINUE").isEqualTo(true))
        .log("Condition was met")
        .to(URI_DIRECT) //To another route
     .endChoice()
     .otherwise()
        .log("I'll try again later")
        .rollback() // rollback processing and keep file in original directory
.endChoice();

这是预期的行为，请参见：

在（post命令）布线完成后执行任何移动或删除操作

更好地回滚您的路由，默认情况下它会将文件保留在源目录中

final String URI_FILE = "file:{{PATH}}";
final String POOLER = "&scheduler=quartz2&scheduler.cron=0+0/10+*+*+*+?";

from(URI_FILE + POOLER)
.pollEnrich().simple("{{URL_CHECKER}}",String.class).aggregationStrategy(new myEstratey())
.choice()
    .when(exchangeProperty("CONTINUE").isEqualTo(true))
        .log("Condition was met")
        .to(URI_DIRECT) //To another route
     .endChoice()
     .otherwise()
        .log("I'll try again later")
        .rollback() // rollback processing and keep file in original directory
.endChoice();
