Springboot应用程序启动后出现错误

Question

我写了一个springboot应用程序，但是它在run方法执行之前给出了错误。我通过调试观察到它进入主方法，但之后它立即给出错误。我检查了pom.xml文件，但没有发现依赖关系有任何问题。

错误是:org.springframework.boot.context.config.ConfigFileApplicationListener.supportsSourceType(Ljava/lang/Class;)Z

你知道吗?

我的app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

Answer 1

删除@Configuration注释

Answer 2

我建议将具有main()函数的类与其他类分开。

基本上创建一个类，里面只有main()函数，另一个类为CommandLineRunner。

的例子:

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

和Runner的单独Class:

@Component
public class ARunner implements ApplicationRunner {
@Override
public void run(ApplicationArguments args) throws Exception
{
// Your code...
}
}
