运行项目，出现此异常。 HTTP响应503。仅在产品环境中找到。开发或预发布(数据库与产品相同)环境即可。
历史代码版本可以部署成功。主要变化是使用 spring-boot 2.0.0.RELEASE 导入我自己的 jar。

    <dependency>
        <groupId>org.eclipse.jetty</groupId>
        <artifactId>jetty-servlet</artifactId>
        <version>9.2.6.v20141205</version>
    </dependency>

Answer 1

您有混合代码。

java.lang.ClassCastException: 
  org.eclipse.jetty.websocket.jsr356.server.ServerContainer 
    cannot be cast to 
  org.apache.tomcat.websocket.server.WsServerContainer
    at org.apache.tomcat.websocket.server.WsFilter.init(WsFilter.java:40)

这表示您有一个 tomcat 依赖项(tomcat websocket 服务器)尝试在 Jetty 内初始化。
