SpringFox Swagger在IBM Liberty 19.0.0.1上没有按预期工作

Question

附在下面（Swagger on Tomcat）（点击放大） - 我的应用程序在Tomcat 9上的Swagger UI

附加（Swagger on Liberty）（点击放大） - 我的应用程序在Liberty 19.0.0.1上的Swagger UI

在Tomcat中，可以看出，200响应主体被清楚地显示出来，并且“试一试”选项的执行是完美无缺的。

但是，在Liberty中，未显示200响应正文，并且“试一试”执行会导致响应主体填充错误，如下所示（截断）：

<H1>Error Page Exception</H1>
<H4>SRVE0260E: The server cannot use the error page specified for your application to handle the Original Exception printed below.</H4>

同时，Liberty控制台有以下错误（向右滚动以获取更多信息）：

Error reported: 406

[ERROR   ] Error Page Exception:
                                                                                                               0-0

                                                                                                               Error Page Exception
                                                                                                               com.ibm.ws.webcontainer.webapp.WebAppErrorReport: SRVE0295E

我的Liberty的server.xml如下：

<?xml version="1.0" encoding="UTF-8"?>
<server description="new server">

    <!-- Enable features -->
    <featureManager>
        <feature>webProfile-8.0</feature>
        <feature>springBoot-2.0</feature>
        <feature>servlet-4.0</feature>
    </featureManager>

    <basicRegistry/>

    <!-- To access this server from a remote client add a host attribute to the following element, e.g. host="*" -->
    <httpEndpoint id="defaultHttpEndpoint"
                  httpPort="9090"
                  httpsPort="9443" />

    <!-- Automatically expand WAR files and EAR files -->
    <applicationManager autoExpand="true"/>

</server>

我的应用程序使用Java 8，Spring Boot（2.1.3）与Spring Integration，Spring Security，Spring REST Docs，Springfox 3.0.0-SNAPSHOT和Log4j 2。

有人可以帮助指出Liberty无法显示Swagger响应或提供“试用”功能背后的根本原因吗？就像我说的那样，在Tomcat 9上也能顺利运行。

真诚的，巴拉特

Answer 1

此问题可能是由于在Liberty 19.0.0.1上部署SpringBoot 2.1.3应用程序，该应用程序支持SpringBoot 1.5和2.0应用程序，但缺乏thin embedded server dependencies from Spring Boot 2.1应用程序的功能。此功能已被添加到Liberty 19.0.0.2。请更新到Liberty 19.0.0.2并重试您的方案。如果更新无法解决问题，我已打开open-liberty issue 6870进行进一步讨论和发现。
