Question

这是背景。我正在尝试将Spring Boot应用程序部署到Websphere Liberty Profile中。我已经在pom文件中进行了必要的更改

战争包
依赖冲突解决方案，以排除和标记为相关依赖项
将主应用程序类更改为扩展SpringBootServletInitializer并实施WebApplicationInitializer。

此时我的期望是应用程序部署并初始化上下文，并准备好为其获取的任何http请求提供服务。

但是我会在日志中看到以下内容

[AUDIT   ] CWWKT0016I: Web application available (default_host): http://localhost:9082/sringbootapp/
[AUDIT   ] CWWKZ0001I: Application sringbootapp started in 8,197 seconds.

这意味着服务器已检测并部署了该应用程序。当我在应用程序中请求服务时，只显示以下日志：

现在这意味着，春天上下文仅在部署应用程序后的第一个请求期间才初始化。

有没有人遇到过这个问题？我错过了什么吗？

Answer 1

我遇到了同样的问题。答案是指定：

<webContainer deferServletLoad="false"/>

请参阅： http://www.ibm.com/support/knowledgecenter/SSCKBL_8.5.5/com.ibm.websphere.wlp.doc/ae/twlp_servlet_load.html

Answer 2

容器中的Spring Boot需要Servlet-3.0。由于您没有在server.xml中明确命名该功能，因此可能就是这种情况。添加它，如下所述： https://www.ibm.com/support/knowledgecenter/was_beta_liberty/com.ibm.websphere.wlp.nd.multiplatform.doc/ae/twlp_setup_feat.html

<featureManager> <feature>servlet-3.0</feature> ... </featureManager>

接下来，我会尝试将WAR添加为应用程序条目，而不是通过dropins目录删除，如下所述： https://www.ibm.com/support/knowledgecenter/was_beta_liberty/com.ibm.websphere.wlp.nd.multiplatform.doc/ae/twlp_dep_war.html

<application context-root="helloworld" type="war" id="helloworld" location="helloworld.war" name="helloworld"/>

location 必须指向你的战争。

在Websphere Liberty Profile中部署时，Spring Boot仅在第一个请求中初始化上下文
