我写了一个springboot应用程序，但它在执行run方法之前给出了错误。我通过debug观察到它进入了main方法，但之后它立即给出了错误。我检查了pom.xml文件，但没有发现依赖项有任何问题。
错误是： org.springframework.boot.context.config.ConfigFileApplicationListener.supportsSourceType(Ljava/lang/Class;)Z 你知道吗？
我的应用程序类是：

@Configuration
@SpringBootApplication
public class ProcessesApplication implements CommandLineRunner {    

private static Logger logger = LoggerFactory.getLogger(ProcessesApplication.class);

@Autowired
private BatchManager batchManager;

public static void main(String[] args) {
    SpringApplication.run(ProcessesApplication.class, args);

}

@Override
public void run(String... args) throws Exception {
    Integer threadCount = 5;        
    try {        
        if (args.length > 1 && args[1] != null && !args[1].trim().isEmpty()) {
            try {
                threadCount = Integer.valueOf(args[1].trim());
            } catch (Exception e) {
               e.getStackTrace(e));
            }
        }

        this.batchManager.setThreadCount(threadCount);
        this.batchManager.setProcessName("Process");
        this.batchManager.start();
    } catch (Exception e) {
        e.getStackTrace(e);
    }
}

}
我的pom.xml是

我建议把班级和学生分开 main() 其他类的函数。
基本上创建一个只有 main() 函数的内部和另一个类 CommandLineRunner .
例子：

@SpringBootApplication
@EnableAsync
public class SpringApp{

    public static void main(String[] args) {
        SpringApplication.run(SpringApp.class, args);
    }
}

还有一个单独的班级 Runner :

@Component
public class ARunner implements ApplicationRunner {

    @Override
    public void run(ApplicationArguments args) throws Exception
    {
        // Your code...
    }
}
