为什么WsSessionListener.sessionCreated()在嵌入tomcat 9中发出`AbstractMethodError`?

时间:2019-01-21 08:52:57

标签: tomcat

我将springboot 2.1.2.RELEASE用于包含嵌入式tomcat 9版本的Web应用程序。

创建新会话时,它在下面的行中发出AbstractMethodError: null异常

https://github.com/apache/tomcat/blob/trunk/java/org/apache/catalina/session/StandardSession.java#L388

  

有问题的侦听器是WsSessionListener

从tomcat 9开始,WsSessionListener删除了sessionCreated()实现,它仅调用父接口HttpSessionListener的默认sessionCreated()方法。这似乎根本不是问题。 (tomcat-embed-core,tomcat-embed-websocket与9.0.14版本相同)


WsSessionListener在tomcat9中:https://github.com/apache/tomcat/blob/trunk/java/org/apache/tomcat/websocket/server/WsSessionListener.java#L22

HttpSessionListener在tomcat9中: https://github.com/apache/tomcat/blob/trunk/java/javax/servlet/http/HttpSessionListener.java#L30


WsSessionListener在tomcat8中: https://github.com/apache/tomcat/blob/TOMCAT_8_0_0/java/org/apache/tomcat/websocket/server/WsSessionListener.java#L22

HttpSessionListener在tomcat8中: https://github.com/apache/tomcat/blob/TOMCAT_8_0_0/java/javax/servlet/http/HttpSessionListener.java#L30


当我使用tomcat 8(springboot 2.0.x)时,不会发生所有问题。有人知道吗? 请给我一些帮助或推荐...

提前谢谢。

2 个答案:

答案 0 :(得分:2)

只是为了更加清晰。问题似乎是类WsSessionListener实现了方法HttpSessionListener#sessionCreated()。 javax.servlet-api 4.X版本中的此方法是默认方法。 Java抱怨有一个对该方法的调用,如果您比较这两种实现,则可以检查出第9版不再实现上述方法:

您的部署环境中可能有3.1.0 javax.servlet-api jar。排除这种依赖性(如@feckless pauper所指出的)应该可以解决该问题。

我重现了该问题,在我的情况下,spring-boot-starter-web 2.2.4.RELEASE取决于spring-boot-starter-tomcat,这取决于tomcat-embed-websocket 9.0.30(Tomcat 9支持Java 8和更高版本,其中的默认方法是接口)。

答案 1 :(得分:0)

我注意到与Spring Boot 2.1.2.RELEASE(嵌入式Tomcat 9.0.14)非常类似的错误。它似乎并没有影响应用程序的运行能力,但是在日志中看到它确实很烦人。

我可以通过从依赖项配置中删除compile(group: 'javax.servlet', name: 'javax.servlet-api', version: '3.1.0')来消除该错误。我相信这与Tomcat提供的servlet API副本引起冲突。
