Springboot 应用程序启动后报错

如何解决Springboot 应用程序启动后报错

我编写了一个 springboot 应用程序，但它在运行方法执行之前出错。我通过调试观察到它进入 main 方法，但之后立即出错。我检查了 pom.xml 文件，但我没有发现任何依赖关系问题。

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

你有什么想法吗？

我的应用类是：

@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

解决方法

删除 "status":"success","postcode":"BR1","postcode_type":"outcode","url":"https:\/\/propertydata.co.uk\/draw?input=BR1","data":[ [ null,null,"3.5" ],[ null,"5.6" ],"6.3" ] ],"process_time":"0.26" 注释

我建议将带有 main() 函数的类与另一个类分开。

基本上创建一个内部只有 main() 函数的类和另一个 CommandLineRunner 类。

示例：

@SpringBootApplication
@EnableAsync
public class SpringApp{

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

还有一个单独的 Runner 类：

@Component
public class ARunner implements ApplicationRunner {

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