Spring Boot启动的报错 Stopping service [Tomcat]

我遇到的问题是项目中使用java_websocket的WebSocketClient，由于性能要求，需要再Controller直接继承WebSocketClient，

在项目启动过程中调试进入springboot框架，大概意思说onClose被识别为内部方法，造循环依赖等问题，具体没去深究，相关错误关键字如下

Eagerly caching bean to allow for resolving potential circular references

Invalid destruction signature

@Controller
@Slf4j
public class ASR2Controller extends WebSocketClient {

    static String asrUrl = "ws://xxx.yyy.zzz.111:8888/client/ws/speech?content-type=content-type=audio/x-raw,+layout=(string)interleaved,+rate(int)8000,+format=(string)S16LE,+channels=(int)1";

    public ConcurrentLinkedQueue<ASRRecognizedResponse> recognized = new ConcurrentLinkedQueue<ASRRecognizedResponse>();
    public ConcurrentLinkedQueue<ASRRecognizedResponse> cached = new ConcurrentLinkedQueue<ASRRecognizedResponse>();

    public ASR2Controller() throws URISyntaxException {

        this(new URI(asrUrl));
    }

    public ASR2Controller(URI serverUri) {
        super(serverUri,new Draft_6455());
    }

故障排除思路：

降低日志调试级别到info，甚至是debug，trace让其输出更多的日志，如果有能力，追踪框架或者tomcat容器最好不过。

本文最终解决办法：

编译成jar文件运行，然后控制台就出现错误日志了。

mvn package -Dmaven.test.skip=true

java -jar web-01.jar

Error starting ApplicationContext. To display the conditions report re-run yourapplication with 'debug' enabled.

===============================后续解决方法=======================================

后来和同事交流他推荐我使用logback，logback这个框架比较优秀，很早之前用过，大家可以自行搜索一下。

对于日志配置好奇的看官可以打开这个类看看

org.springframework.boot.context.logging.LoggingApplicationListener

修改yaml（application.yml）中的日志级别增加配置文件解决问题。

application.yml

logging:
  level:
    root: debug
  path: C:\\logs

logback-spring.xml

<?xml version="1.0" encoding="UTF-8"?>
<configuration  scan="true" scanPeriod="60 seconds" debug="false">

     <springProperty scope="context" name="applicationName" source="spring.application.name"/>
