Question

我有一个春季启动应用程序。打包为war文件，内容如下

static
org - springframework - boot -loader - SpringClasses
META-INF
    - MANIFEST.MF
    - maven -my.group.id - my-artifact-id - pom.xml & pom.properties
WEB-INF
    - lib (contains all jars)
    - classes (my main application's classes)
    - some other stuff
    - web.xml
    - main-servlet.xml

其中web.xml和main-servlet.xml是配置xml＆＃39;

我试过，从springBoot应用程序执行如下操作：

@EnableWebMvc
@EnableAutoConfiguration
@Configuration
@ImportResource({ "classpath:main-servlet.xml"})
public class FakeAppBooter {

    public static void main(String args[]) {
        SpringApplication.run(FakeAppBooter.class, args);
        System.out.println("Test");
    }

    public DispatcherServlet mvcDispatcherServlet() {
            XmlWebApplicationContext ctx = new XmlWebApplicationContext();
            ctx.setConfigLocation("classpath:main-servlet.xml");
            DispatcherServlet dispatcherServlet = new DispatcherServlet(ctx);
            return dispatcherServlet;
        }

        @Bean
        public ServletRegistrationBean mvcServletRegistrationBean() {
            ServletRegistrationBean bean = new ServletRegistrationBean();
            bean.setServlet(mvcDispatcherServlet());
            ArrayList<String> list = new ArrayList<>();
            list.add("/");
            bean.setUrlMappings(list);
            return bean;
        }
}

然而，在启动时，我得到：

Caused by: java.io.FileNotFoundException: class path resource [main-servlet.xml] cannot be opened because it does not exist
        at org.springframework.core.io.ClassPathResource.getInputStream(ClassPathResource.java:172)
        at org.springframework.beans.factory.xml.XmlBeanDefinitionReader.loadBeanDefinitions(XmlBeanDefinitionReader.java:329)
        ... 25 more

我需要这些来为我的应用程序定义servlet。

我该怎么办？

您的问题的解决方案：

当您使用SpringBoot时从不关心您的web.xml，因为SpringBoot本身将通过EmbeddedServletContainer初始化您的Web容器，最好是TomcatEmbeddedServletContainer。因此，忽略您的web.xml配置并解决您的第一个问题
您还没有将main-servlet.xml放在适当的类路径中。复制main-servlet.xml并将其粘贴到项目的 src文件夹中。

相应地更改您的代码

import java.util.ArrayList;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
//Place your Imports Appropriately

/**

  @EnableWebMvc
  @EnableAutoConfiguration(exclude=DataSourceAutoConfiguration.class)
  @ImportResource({ "classpath:main-servlet.xml"})
  @ComponentScan
  public class FakeAppBooter {
  private ApplicationContext ctx;
  public static void main(String[] args) {
  SpringApplication.run(FakeAppBooter.class, args);
  System.out.println("Test>>>>");
 }
  public DispatcherServlet mvcDispatcherServlet() {
     ctx = new ClassPathXmlApplicationContext();
     ((AbstractRefreshableConfigApplicationContext)                       ctx).setConfigLocation("classpath:main-servlet.xml");
     DispatcherServlet dispatcherServlet = new DispatcherServlet();
      return dispatcherServlet;
   }

  @Bean
    public ServletRegistrationBean mvcServletRegistrationBean() {
    ServletRegistrationBean bean = new ServletRegistrationBean();
    bean.setServlet(mvcDispatcherServlet());
    ArrayList<String> list = new ArrayList<>();
    list.add("/");
    bean.setUrlMappings(list); 
    return bean;
    }
  }

main-servlet.xml
我以非常简单的方式保存了main-servlet.xml。

main-servlet.xml file
