标签： spring-boot gwt

我有一个GWT应用程序（gwt 2.8），我想添加Spring-Boot依赖项（1.5.3.RELEASE）。我想要一个独立的可执行战争应用程序

这是我的web.xml：

其中FonemsWebappApplication是我的spring-boot入口点类。

package com.mycompany.fonems.webapp.server;

@Slf4j
@Configuration
@ComponentScan(basePackages = { "com.mycompany.fonems" })
@EnableAutoConfiguration(exclude = { DataSourceAutoConfiguration.class, HibernateJpaAutoConfiguration.class,
        ValidationAutoConfiguration.class })
public class FonemsWebappApplication {

    @Inject
    private Environment env;

    public static void main(String[] args) throws UnknownHostException {
        log.info("-------------------------------\tApplication is starting ...");

        SpringApplicationBuilder app = new SpringApplicationBuilder(FonemsWebappApplication.class);
        Environment env = app.run(args).getEnvironment();
        String portNumber = env.getProperty("server.port");
        log.info("\n----------------------------------------------------------\n\t"
                + "Application '{}' is running! Access URLs:\n\t" + "Local: \t\thttp://127.0.0.1:{}\n\t"
                + "External: \thttp://{}:{}\n----------------------------------------------------------",
                env.getProperty("spring.application.name"), portNumber, InetAddress.getLocalHost().getHostAddress(), portNumber);

        log.info("-------------------------------\tApplication is running");

    }
}

我启动了我的应用程序。它似乎从没有错误开始。尽管如此，在我的网络浏览器中，我有这样的错误：
访问/fonemswebapp/FONEMSWebMessageService.rpc 时出现问题 找不到路径

这里有日志：

为什么在日志中我们看到ServletDispatcher出现了？ 在我的应用程序中，我应该定义一个ServletDispatcher吗？如果是这种情况，如何定义我的5个web.xml servlet并过滤以考虑？ 奇怪的是，当我从GWT开发模式（eclipse插件）启动它时，应用程序运行并正常响应。

谢谢
