Welche Ursachen und welche Unterschiede bestehen zwischen NoClassDefFoundError und ClassNotFoundException? 15 answers

Ich habe ein mit Spring-Annotationen versehenes Scheduler-Programm geschrieben, aber wenn ich es ausführe, wird die Fehlermeldung im Post-Titel angezeigt.

SchedulerConfig.java

import java.util.concurrent.Executor;
import java.util.concurrent.Executors;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.scheduling.annotation.EnableScheduling;
import org.springframework.scheduling.annotation.SchedulingConfigurer;
import org.springframework.scheduling.config.ScheduledTaskRegistrar;

import com.fwd.pmap.scheduler.SchedulerApp;

@Configuration
@EnableScheduling
public class SchedulerConfig implements SchedulingConfigurer {

    @Bean
    public SchedulerApp bean() {
        return new SchedulerApp();
    }

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

    @Bean(destroyMethod="shutdown")
    public Executor taskExecutor() {
        return Executors.newScheduledThreadPool(4);
    }
}

SchedulerApp.java

import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;

import com.fwd.pmap.memberInterfaceFile.CsvReader;
import com.fwd.pmap.memberInterfaceFile.CsvWriter;;

@Component
public class SchedulerApp
{
    @Scheduled(cron="0 0 17 * ? *")
    public void importInterfaceFile()
    {
        CsvReader reader = new CsvReader();
        try {
            reader.importInterfaceFile();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    @Scheduled(cron="0 0 6 * ? *")
    public void generateInterfaceFile()
    {
        CsvWriter writer = new CsvWriter();
        try {
            writer.generateInterfaceFile();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

Und die Hauptklasse zum Starten des Scheduler-Jobs

import org.springframework.context.annotation.AnnotationConfigApplicationContext;
import org.springframework.context.support.AbstractApplicationContext;

public class SchedulerMain
{
    @SuppressWarnings({ "unused", "resource" })
    public static void main(String[] args) {
        AbstractApplicationContext context = new AnnotationConfigApplicationContext(SchedulerConfig.class);
    }
}

Die Fehlermeldung lautet:

Es hat vor 2 Monaten gut funktioniert, bis ich den Code kürzlich überarbeitet habe und festgestellt habe, dass er defekt ist. Jeder kann einen Zeiger geben?
