Spring Java Config:不使用web.xml的Tomcat部署 [英] Spring Java Config: Tomcat deploy without web.xml

问题描述

我构建了一个没有任何XML的Java配置的Spring MVC应用程序.我可以在笔记本电脑上部署并启动该应用程序，而不会出现任何问题.但是，一旦我尝试在我的测试服务器(tomcat 7)上部署应用程序，就会收到以下消息:

I built a java configured Spring MVC application without any XML. I can deploy and start the application on my laptop without any problems. But as soon as I try to deploy my application on my testserver (tomcat 7), I receive following message:

HTTP Status 404 - The requested resource (/[application context]/) is not available.

我使用Eclipse Maven插件构建应用程序.是否可以在没有web.xml的情况下部署应用程序，如果没有，这是我真正需要的基本web.xml?

I build my applications using the Eclipse Maven plugin. Is it possible to deploy the application without the web.xml and if not, which is the basic web.xml I really need?

Maven WAR插件:

Maven WAR Plugin:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-war-plugin</artifactId>
    <version>${maven.war.plugin.version}</version>
    <configuration>
        <failOnMissingWebXml>false</failOnMissingWebXml>
    </configuration>
</plugin>

WebAppInitializer:

WebAppInitializer:

@Order(value = 1)
public class WebAppInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {

    @Override
    public void onStartup(ServletContext servletContext) throws ServletException {
        super.onStartup(servletContext);
    }

    @Override
    protected Class<?>[] getRootConfigClasses() {
        return new Class[] { HibernateConfig.class, SecurityConfig.class, HibernateDaoConfig.class };
    }

    @Override
    protected Class<?>[] getServletConfigClasses() {
        return new Class[] { WebAppConfig.class };
    }

    @Override
    protected String[] getServletMappings() {
        return new String[] { "/" };
    }

    @Override
    protected Filter[] getServletFilters() {
        return new Filter[]{};
    }
}

更新:catalina.out

Update: catalina.out

SEVERE: The web application [/[appname]] appears to have started a thread named [Abandoned connection cleanup thread] but has failed to stop it. This is very likely to create a memory leak.

推荐答案

我将升级到最新的Tomcat版本，然后查看它是否有效(以隔离您的问题).在较旧的Tocmat服务器上使用新的spring功能(例如:java config等)有很多问题.例如，请参见:

I'd upgrade to the latest Tomcat version and see if that works (to isolate your issue). There are many issues with using the new spring features (ex: java config, etc.) with older Tocmat servers. For example, see: http://docs.spring.io/autorepo/docs/spring-framework/3.1.x/javadoc-api/org/springframework/web/WebApplicationInitializer.html

在Tomcat下映射到'/'

Mapping to '/' under Tomcat

Apache Tomcat将其内部DefaultServlet映射为"/"，并且在Tomcat版本< = 7.0.14上，不能以编程方式覆盖此>> servlet映射. 7.0.15解决了此问题.覆盖"/" >> servlet映射也已在GlassFish 3.1下成功测试.

Apache Tomcat maps its internal DefaultServlet to "/", and on Tomcat versions <= 7.0.14, this >>servlet mapping cannot be overridden programmatically. 7.0.15 fixes this issue. Overriding the "/" >>servlet mapping has also been tested successfully under GlassFish 3.1.
