运行项目，得到这个异常。 Http 响应 503。仅在产品环境中找到。开发或预发布（数据库同产品）环境都可以。
历史代码版本可以部署成功。主要的变化是用 spring-boot 2.0.0.RELEASE.

导入一个我自己的 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）试图在 Jetty 中初始化。

org.eclipse.jetty.websocket.jsr356.server.ServerContainer 无法转换为 org.apache.tom cat.websocket.server.WsServerContaine

org.eclipse.jetty.websocket.jsr356.server.ServerContainer cannot be cast to org.apache.tom cat.websocket.server.WsServerContaine
