Question

比方说，我有一个Spring Boot Web应用程序-它可以通过gradle（嵌入式tomcat）运行。但我还需要以标准方式将战争部署到应用服务器中。该应用程序应如何配置？标准的web.xml和xml配置？

目前我有类似的东西

@SpringBootApplication

公共类MyApplication扩展了SpringBootServletInitializer {

public static void main(String[] args) {
    System.setProperty("spring.profiles.active", "dev");
    SpringApplication.run(MyApplication.class, args);
}

@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
    return application.sources(MyApplication.class);
}

@Configuration
@ConditionalOnWebApplication
public static class WebConfiguration {

    @Bean
    public ServletListenerRegistrationBean<ServletContextListener> registerClientCookieConfigListener () {
        ServletListenerRegistrationBean<ServletContextListener> srb =
                new ServletListenerRegistrationBean<>();
        srb.setListener(new MyConfigListener());
        return srb;
    }

    @Bean
    public ServletListenerRegistrationBean<HttpSessionListener> registerMySessionConfigListener () {
        ServletListenerRegistrationBean<HttpSessionListener> srb =
                new ServletListenerRegistrationBean<>();
        srb.setListener(new MySessionConfigListener());
        return srb;
    }


    @Bean
    public FilterRegistrationBean registerLoginFilter() {
        FilterRegistrationBean filter = new FilterRegistrationBean(new MyFilter());
        filter.setUrlPatterns(Collections.singletonList("/*"));
        return filter;
    }

    @Bean
    public ServletRegistrationBean registerSAMLDispatcherServlet() {
        ServletRegistrationBean bean = new ServletRegistrationBean(
                new DispatcherServlet(), "/test/*");
        bean.setLoadOnStartup(1);
        return bean;
    }
}

}

，即1：1映射到web.xml。甚至可以在没有web.xml的情况下将其部署到应用服务器？

Answer 1

您不需要web.xml即可将Spring Boot部署到独立的tomcat服务器或任何其他Web服务器。

spring boot不依赖xml配置，它会自动配置与分派器servlet等效的对象。

要将Spring Boot应用程序部署到另一台服务器，您需要更新包装以在Maven中发动战争

 <packaging>war</packaging>

并告诉Maven，Web服务器将在运行时可用，并且不要将其与范围provided一起打包

<dependency>
   <groupId>org.springframework.boot</groupId>
   <artifactId>spring-boot-starter-tomcat</artifactId>
   <scope>provided</scope>
</dependency>

Spring Boot-可执行的战争也可以部署到应用服务器
