Question

我遇到了一些问题。我正在使用所有基于Java的配置，减去logback.xml，因为我没有找到一个很好的例子来说明如何在没有XML的情况下配置它。

无论如何我的问题是我什么时候

mvn clean build

失败，因为找不到web.xml。这是一个问题，因为我正在使用具有Maven插件的QueryDSL来生成它需要的类。所以我需要能够在没有web.xml的情况下进行Maven构建，或者我需要能够在没有Maven的情况下生成QueryDSL元类。

我的web.xml已替换为此代码。

import org.springframework.web.WebApplicationInitializer;
import org.springframework.web.context.ContextLoaderListener;
import org.springframework.web.context.support.AnnotationConfigWebApplicationContext;
import org.springframework.web.servlet.DispatcherServlet;

import javax.servlet.ServletContext;
import javax.servlet.ServletException;
import javax.servlet.ServletRegistration;

public class ApplicationInitializer implements WebApplicationInitializer {

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

        /**
         * If no active profile is set via -Dspring.profiles.active then the application
         * will default to development mode
         */
         container.setInitParameter("spring.profiles.default", "dev");

        /**
         * create the root Spring application context
         */
        AnnotationConfigWebApplicationContext rootContext = new AnnotationConfigWebApplicationContext();
        rootContext.setDisplayName("IGDb");
        rootContext.register(AppConfig.class);

        /**
         * manage the lifecycle of the root application context
         */
        container.addListener(new ContextLoaderListener(rootContext));

        /**
         * register and map the dispatcher servlet
         */
        ServletRegistration.Dynamic dispatcher = container.addServlet("dispatcher", new DispatcherServlet(rootContext));
        dispatcher.setLoadOnStartup(1);
        dispatcher.addMapping("/");
    }
}

试试这个：

<plugin>
 <groupId>org.apache.maven.plugins</groupId>
 <artifactId>maven-war-plugin</artifactId>
 <version>2.1.1</version>
 <configuration>
    <failOnMissingWebXml>false</failOnMissingWebXml>
 </configuration>
</plugin>

使用WebApplicationInitializer而不是web.xml构建Maven
