在没有web.xml的情况下标记应用程序可分发用于Tomcat会话复制 [英] Marking application without web.xml distributable for Tomcat session replication

问题描述

我有基于Spring的应用程序并使用编程方法（ AbstractAnnotationConfigDispatcherServletInitializer ）进行应用程序配置。

I have Spring based application and using programmatic approach (AbstractAnnotationConfigDispatcherServletInitializer) for app configuration.

要使tomcat会话复制工作，我需要'标记'app distributable 使用 web.xml中的< distributable /> 标记，但正如我所提到的，我正在使用程序化风格，例如

To make tomcat session replication work I need to 'mark' app distributable using <distributable/> tag in web.xml, however as I mentioned I am using programmatic style, e.g.

public class WebInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {

    @Override
    public void onStartup(ServletContext servletContext) throws ServletException {

            String activeProfile = activeProfile();

            if (isNotEmpty(activeProfile)) {
                servletContext.setInitParameter("spring.profiles.active", activeProfile);
            }

            super.onStartup(servletContext);

        }
    }

我找不到任何文档关于如何使用Spring配置来实现它，所以我的问题是，是否有可能在没有web.xml的情况下拥有可分发的应用程序？我无法将所有配置移动到web.xml，所以任何帮助都表示赞赏。

I can't find any docs about how to do it using Spring configs, so my question here is that, Is it possible to have distributable app without having web.xml? I can't move all configs to the web.xml, so any help is appreciated.

推荐答案

有几个选项你不能从基于Java的配置设置，其中一个是< distributable /> 另一个是错误页面。

There are several option you cannot set from Java based configuration, one of them is <distributable /> another is the error-pages.

为此你还需要 web.xml ，只需创建一个尽可能为空的 web.xml ，仅包含< distributable /> 。其他所有内容都可以保留在基于Java的配置中。

For that you still need a web.xml, just create an as empty as possible web.xml and only include <distributable />. Everything else can remain in Java based configuration.

<web-app
        version="3.0"
        xmlns="http://java.sun.com/xml/ns/javaee"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">

    <distributable />

</web-app>
