[GitHub] [shardingsphere-elasticjob] TeslaCN opened a new issue #1551: Using lambda implementation of interface SimpleJob may cause job conflict exception

TeslaCN opened a new issue #1551:
URL: https://github.com/apache/shardingsphere-elasticjob/issues/1551


   ## Bug Report
   
   ### Actual behavior
   
   ```
   Exception in thread "main" org.apache.shardingsphere.elasticjob.infra.exception.JobConfigurationException: Job conflict with register center. The job 'lambda-simple' in register center's class is 'org.apache.shardingsphere.elasticjob.lite.example.once.LambdaMain$$Lambda$7/542365801', your job class is 'org.apache.shardingsphere.elasticjob.lite.example.once.LambdaMain$$Lambda$8/542365801'
   	at org.apache.shardingsphere.elasticjob.lite.internal.config.ConfigurationService.checkConflictJob(ConfigurationService.java:86)
   	at org.apache.shardingsphere.elasticjob.lite.internal.config.ConfigurationService.setUpJobConfiguration(ConfigurationService.java:70)
   	at org.apache.shardingsphere.elasticjob.lite.internal.setup.SetUpFacade.setUpJobConfiguration(SetUpFacade.java:66)
   	at org.apache.shardingsphere.elasticjob.lite.internal.schedule.JobScheduler.<init>(JobScheduler.java:87)
   	at org.apache.shardingsphere.elasticjob.lite.api.bootstrap.impl.ScheduleJobBootstrap.<init>(ScheduleJobBootstrap.java:41)
   	at org.apache.shardingsphere.elasticjob.lite.example.once.LambdaMain.main(LambdaMain.java:47)
   ```
   
   ### Example codes for reproduce this issue (such as a github link).
   ```java
           SimpleJob simpleJob = System.out::println;
           new ScheduleJobBootstrap(REGISTRY_CENTER, simpleJob,
                   JobConfiguration.newBuilder("lambda-simple", 3)
                           .cron("0/5 * * * * ?")
                           .shardingItemParameters("0=Beijing,1=Shanghai,2=Guangzhou")
                           .jobErrorHandlerType("log")
                           .overwrite(true)
                           .build(),
                   TRACING_CONFIGURATION)
                   .schedule();
   ```
   
   ### Reason analyze (If you can)
   Lambda expression will be converted to a synthetic class. The class name is not fixed and it may be different each startup.
